List of Illustrations
Chapter 2: Physical Aspects of Sexual Development
Figure 2.1 Male testosterone levels
Figure 2.2 Female testosterone levels
Chapter 3: Anatomy and Physiology in the Male
Figure 3.1 A schematic sagittal diagram of the adult male genitourinary tract (not to scale)
Figure 3.2 A schematic representation of an erect circumcised penis. The paired corpora cavernosa run parallel along the shaft surrounded by the membranous tunica albuginea while underneath the corpora spongiosum is fitted around the urethra and starting as the penile bulb (not shown but see Figure 3.4) and terminates as the penile glans
Figure 3.3 A diagrammatic illustration of the corpora cavernosal mechanism of erection of the penis (see text for details). The size of the arrows is an indication of the amount of blood flow into and from the vessels involved
Figure 3.4 Schematic diagrams of the medial (A) and ventral (B) aspects of the penis. The course of the corpus spongiosum is shown in (A) while the dispositions of the ischiocavernosus and bulbocavernosus striated muscles are shown in (B). The latter is a bipennate structure with its medial raphe and two rows of muscle fibers facing in opposite diagonal directions; this gives forceful contractions for ejaculation but with restricted movement. The frenulum and coronal edge of the glans are illustrated (see text for details)
Figure 3.5 A graphic ‘cusp’ representation of the sexual response cycle in the male during two serial sexual scenarios. Cusp systems have a sudden change caused by a smooth acceleration characterized mathematically by Catastrophe theory. Orgasm is an example of a ‘cusp catastrophe’ where behaviour is smooth up to the cusp the system then trips over into a completely different behaviour and orgasm occurs. In the first scenario (A) a desire phase (1) precedes the excitement phase (2) and the increasing central sexual arousal reaches a cusp that initiates ejaculation and orgasm. There is then a subsequent resolution (3) back to the basal level. During this resolution phase (3) there is a refractory period (post orgasmic refractory time, PERT) when an immediate further erection/orgasm cannot occur. A subsequent sexual arousal (B), after the ending of the PERT, has the same sequences as the previous but as shown in the diagram the central sexual arousal, thus pleasure, is usually less than the first (see text for details)
Chapter 4: Anatomy and Physiology in the Female
Figure 4.1 A highly schematic diagram of the female pudenda with the labia majora and minora removed for clarity. The periurethral glans area of the vaginal vestibule stretches from underneath the clitoris to the top of the introitus
Figure 4.2 A graphic representation of the female sexual response cycles for two scenarios. The first (A) is represented by a cusp system. Cusp systems have a sudden change caused by a smooth acceleration characterized mathematically by Catastrophe theory. Orgasm is an example of a ‘cusp catastrophe’ where behaviour is smooth up to the cusp, the system then trips over into a completely different behaviour and orgasm occurs. In A (solid line), a desire phase (1) precedes the excitement phase (2) created by sexual stimulation. The rising central sexual arousal reaches a cusp that initiates orgasm and then a partial resolution (3) of the arousal until a further bout of stimulation (2) in B arrests the resolution and a second central arousal reaches the cusp and the induction of a further orgasm. This then induces the subsequent resolution phase (3) that returns the central arousal back to near basal levels. The second scenario (C, dotted line) again has an initial desire phase (1) preceding the excitement phase (2) but this time the central sexual arousal does not reach the level required to activate the orgasm cusp, orgasm does not occur, so the resolution phase (3) takes a considerably longer time to resolve back to basal level
Figure 4.3 A highly schematic sagittal view of the female genitalia (labia majora and minora not shown). The septum between the anterior wall of the vagina and the urethra contains Halban's fascia (see text). A possible site for the controversial G-spot is shown just around the junction of the bladder and urethra

Figure 15.2 Treatment diagram to illustrate the recommended steps for intervention. After initial assessment, if medical problems are found, further medical examination and treatment are warranted. If psychological or couple issues are first detected, client may benefit from treatment focusing on cognitive processing, mindfulness skills and behavioural changes. In some cases, couple therapy is needed. Psychoeducation is imperative to overcome unfavourable beliefs and to define and adjust expectations. If there are little or no motivations to be sexual, sexual stimuli are not satisfactory, thoughts content is distracting or disturbing, mindfulness integrated CBT is recommended. Address sexual scripts and develop alternatives as needed. Address pleasure. Off-label medications are indicated only if previous steps were unsuccessful, after the client received full explanation on the limitations of medical treatment.

Figure 19.1 Pain assessment algorithm. A thorough pain history and physical exam are required to determine whether pain is idiopathic or due to a known disease. It is notable that treatments may fail to relieve pain and associated symptoms, and when no cause of pain can be found, a patient is considered to have an idiopathic pelvic pain syndrome. If no organ-specific symptoms are found, referrals for pain management may be made. When specific organs are implicated, it is recommended that a comprehensive phenotypic assessment be conducted to determine the respective contributions of urological/gynaecological, psychosocial, organ-specific, infectious, neurological, pelvic floor tenderness and sexual factors. Positive domains can further direct the referral and treatment process.

Series Foreword
Why do we need an ABC of Sexual Health? The answer is straightforward; the subject is important, which is often not advised about and often not taught in medical school or at the post graduate level. When questioned as to what is important in a happy marriage, sexual relationships were considered very important and when patients had concerns they wanted more information and healthcare professionals to initiate discussion. Far too often healthcare professionals wait for the patient to raise the subject, whereas they need to be more proactive. In a recent survey, of more than 450 cardiologists, 70% gave no advice, 54% saying there was a lack of patient initiative and 43% saying they didn't have the time. In this vacuum, ABC of Sexual Health is clearly needed so that healthcare professionals can know more about this unmet need.
In 1970, the World Health Organization summarised the right to sexual health, including it as part of the fundamental rights of an individual.
A capacity to enjoy and control sexual health and reproductive behaviour in accordance with social and personal ethics
Freedom from fear, shame, guilt, false beliefs and other factors inhibiting sexual response and impairing sexual relationships
Freedom from organic disorders, diseases and deficiencies that interfere with sexual and reproductive function
So nearly 50 years later it is right that we ask ourselves “how are we doing?” The short answer is: not well enough. There are many disciplines involved and access to these should become routine, and this book forms an essential beginning.
Dr. Graham Jackson Cardiologist and Chairman of the Sexual Advice Association

Chapter 1Psychosexual Development

Overview
Psychosexual development is not limited to childhood and adolescence but extends through adult life
Early psychoanalytic views of the process are still influential but more recent ideas such as consumerist and feminist perspectives offer a more societal emphasis
It is important to consider the impact of the aspects of law and culture that relate to psychosexual development
Clinicians need to be aware of the implications of these issues and the various factors impacting on development in their consultations with patients.
Introduction
Interest in psychosexual development has tended to focus around managing problems, particularly those associated with risks and their management. These areas include sexual abuse in childhood and early adolescence, unwanted pregnancy and sexually transmitted diseases (STDs) in adolescence and early adulthood and functional sexual difficulties in adults. In contrast, the interest, for example of adolescents has been shown to be more in the rite of passage and recreational aspects of sexual activity. There has also been a concentration on childhood and adolescence, with adult psychosexual development being a poor relation and any emphasis for older people being on dysfunctions and disorders rather than the expected course of development. Development through the life cycle involves important areas such as sexual identity, couple relationship issues, fertility and ageing.
Psychoanalytic views
Probably, the most familiar schema of sexual development in childhood and adolescence is that proposed by Freud (Table 1.1). This still has currency in many modern textbooks despite having long been superseded, not only outside of the world of psychoanalysis, but also generally among psychotherapists. A primary criticism is that it pathologizes variations in sexual development, in particular gay and lesbian relationships. With the passage of time, Freud's emphasis on instinct and drive was replaced by highlighting the importance of relating and relationship and then broadened to recognize the importance of learning and culture. Freud's theories assume that children are caught in hidden conflicts between their fears and their desires, whereas the environmental learning view is of identification through observation and imitation. Modern psychoanalytic views include a wide range of innovative ideas such as that the various dynamics in childhood produce a psychosexual core which is unstable, elusive and never felt to be really owned.
Table 1.1 Freud on psychosexual development
Oral stage 0–2 years
Desires are focussed on the lips and mouth. The mother becomes the first love-object, a displacement from the earliest object of desire, the breast
Anal stage 2–4 years of age
In this stage, the anus is the new auto-erotic object with pleasure being obtained from controlling bladder and bowel movement
Phallic stage 4–7 years of age
In this third stage, awareness of and touching the genitals is the primary source of pleasure
Latency period 7–12 years of age
During this time, sexual development is more or less suspended and sexual urges are repressed
Genital phase 13 years + (or from puberty on)
In this final phase, sexual urges are direct onto opposite sex peers with the primary focus of pleasure of the genitals
Consumerist view
At the other end of the spectrum are ideas that take a societal perspective, such as consumer culture bringing sexuality into the world of commerce. Sex is used to sell products through sexiness and physical attractiveness being closely connected with the goods we buy and are seen to own. This aspect of sex and consumerism is particularly directed towards girls and women. A further development is when sex itself is marketed as pleasure or the idea of sexual self-expression is promoted. The world is sexualized, and there is a seduction into the world of responding to sexual impulse. On the Internet in particular, representations of the body become products to buy. This becomes the world into which children and adolescents are socialized and encouraged to participate. As we grow up, sexuality becomes increasingly focussed on technique and performance with a tendency for it to come to resemble work risking the loss of much of its intimate and caring qualities.
Feminist views
The feminist perspective is that gender shapes our personality and social life and that our sexual desires, feelings and preferences are deeply rooted by our gender status. The identification between mothers and daughters leads girls to become very relationship-orientated. This promotes the connection of sex with intimacy and the valuing of its caring and sharing aspects. It develops as a means of communication and intimacy rather than a source of erotic pleasure. In contrast, boys develop a more detached relationship with their mothers and do not have the same kind of identification with their fathers and this leads them to be more goal-orientated around sexuality. There is more of an emphasis on pleasure and on performance. It is also argued that girls' identification with their mothers makes their heterosexual identification weaker than that of boys.
Definition of childhood and adolescence
The nature of childhood and adolescence has been subject to debate and controversy. Whilst all acknowledge that the nature of both has changed in Western culture over the centuries, there is some dispute about when the idea of childhood as a distinctive phase began, and it has been suggested that the idea we have currently of adolescence did not exist before the beginning of the twentieth century. It has also been argued that the concept of childhood makes children more vulnerable including to sexual exploitation and abuse. The idealization of childhood may also contribute to the sexual attraction of children to certain adults.
The impact of law and culture
Aspects of the definitions of childhood and adolescent become enshrined in law particularly in defining the age of consent for sex and what kinds of sexual practices are legal. It also defines a framework for marriage, and alongside this are cultural issues about the acceptability of sexual relationships outside of this. In different countries, the age of consent varies from 12 to 21 for heterosexual, gay and lesbian relationships, but in many countries same-sex relationships are still illegal. The position is complicated by the fact that these arrangements are often subject to review and potential change.
Although it is clearly interwoven, law is only one of the forces at work here as family, religion, culture and mass media also influence teenage attitudes and behaviour. All these forces work together in ways that overlap, support and sometimes contradict one another in the emergence of a normative version of teenage sexuality.
Childhood development
Young children show behaviours that indicate awareness of sexual organs and pleasuring very early and preschoolers are often puzzled by sexual anatomical differences. By the age of 2 or 3, they become aware of their gender and aspects of gender role. Children often have a need for the validation and correction of their sexual learning, but adults often do not feel well-informed about childhood sexuality and, as a consequence, are not confident about how to respond in their care of children. Play such as doctors and nurses and looking at genitals are all common during the preschool and early school years and as many as half of all adults remember this kind of childhood sexual play. The discovery of such activities can give parents and caregivers an opportunity to educate and share values. An example of this would be that another person should not touch them in a way that makes them feel afraid, confused or uncomfortable. Activities between children such as those involving pain, simulated or real penetration or oral–genital contact should raise concerns and may be related to exposure to inappropriate adult entertainment or indicate sexual abuse. School-age children are usually able to understand basic information about sexuality and sexual development and may look to various sources for information, such as friends and the Internet.
Adolescent development
Early teenage development can be characterized by concerns about normality, appearance and attractiveness. As girls' physical development is usually more advanced than that of boys of the same age, they may experience sexual feelings earlier and be attracted to older, more physically mature boys. Those who have early intercourse have been found to have lower self-esteem than virgins, unlike boys for whom intercourse is more socially acceptable. For boys, there is evidence that both peers and families can potentially either support or undermine sexual development and that health care providers may have more influence than they presume. The middle phase sees the exploration of gender roles and an awareness of sexual orientation. Fantasies are idealistic and romanticized, and sexual experimentation and activity often begin in relationships that are often brief and self-serving. Online communication is used for relationship formation and sexual self-exploration but also carries risks of unwanted or inappropriate sexual solicitation.
In late adolescence, there is an acceptance of sexual identity and intimate relationships are based more on giving and sharing, rather than the earlier exploration and romanticism. Research among students has suggested that first experiences of intercourse in late adolescence lead males to be more satisfied with their appearance, whereas females became slightly less satisfied. In all this, it is important to bear in mind the wide variability in individual adolescent development which is evident to all who work with this age group.
Factors impacting on development
Impairment or delay in psychosexual development can be caused by a number of factors including:
physical developmental disorders
some chronic illnesses and treatments
lack of appropriate educational opportunities
absent or poor role models
Promoters of early sexualization include
inappropriate comments and attention from adults
sexual abuse
viewing pornography
sexual experiences with peers at a young age
The effects of early puberty in girls can include early sexual behaviour and an increased number of lifetime sexual partners. Research has confirmed that both early puberty and late puberty in girls are associated with low self-esteem. Disruption in development can also be brought about by:
education into misleading or inaccurate information about sex
experiencing or witnessing sexually abusive or violent acts
sexual humiliations or rejections
Adult development
The main developmental tasks for young adults are completing the development of adequate sexual confidence and functioning and establishing the potential for desired couple relationships. The latter may range through a spectrum of possible arrangements from marriage to one-night stands as lifestyle choices. Over the period of fertility, decisions about children are taken either as choices or responses to physical limitations. This is followed by more marked accommodation in response to ageing. The decrease in frequency of sexual activity at this point is thought to involve relational as well as physical factors. Social attitudes tend to claim sex as the province of the young and fit and that there is something distasteful about interest in sex and sexual activity beyond young adulthood, particularly in the elderly. Later in life, but potentially at any point, adjustments to illness or disability may have to be made (Table 1.2 and 1.3).
Table 1.2 Adult psychosexual development tasks
Consolidating sexual identity and orientation (teens and twenties)
Developing adequate sexual confidence and functioning (late teens and twenties)
Establishing the potential for desired couple relationships (late teens and twenties)
Managing issues around fertility (twenties, thirties and forties)
Adjusting to the effects of ageing (forties onwards)
Facing and dealing with loss (forties or fifties onwards)
Adjusting to illness and disability (at any point but particularly in the elderly)
Table 1.3 Learning points for clinicians
Expressions of sexuality in childhood need to be carefully assessed to avoid missing situations that need intervention or pathologizing expression that fall within the range of normal development
Developmental issues and adolescent needs should not to be obscured by preoccupations about risk
Care needs to be taken that valid developments in sexual orientation and preferences are not pathologized
There needs to be an awareness of the relevance of developmental issues throughout the life cycle
Problems related to sexuality may be partly a result of a difficulty in transition through a developmental stage or of a past stage that was not successfully negotiated
It is important to be aware of the assumptions and values that underlay ideas about normal development and the potential conflict between societal concerns and individual aspirations

Overview
This chapter focuses on the nature aspects of female–male development and differences
Step 1 takes place at the conception when the genotypic sex is determined by XX or XY
Step 2 starts 7 weeks later with the development of the gonadal sex. Without interference of testosterone, the default is female. With testosterone, the gonads, the genitals and the brain will ‘grow male’
From birth to puberty, there is no activity of gonadal hormones
Puberty is the last phase of differentiation and preparation for adult life and reproduction
After puberty, the gonadal hormones have only activational function and no more organizational function.
Introduction
Talking about sexuality is also talking about female/male differences, a major topic in the history of our human race. Depending on time and culture more or less value has been attributed to the biological, the psychological or the social influences, sometimes denying the importance of specific elements. A striking example of that nurture–nature debate happened three decades ago in Western culture. Then, the predominant idea was that education (=nurture) was the major reason for the difference between the sexes, and the biological influence was nearly completely denied. So, the toys for children were adjusted. Girls were given Dinky Toys and boys got dolls. But nature proved stronger than education. The dolls were used as the enemy and the Dinky Toys were sometimes pampered by the girls. One cannot simply erase millions of years of evolution.
Talking female–male differences is very tricky, as it easily can be seen as discriminating one group. However, one cannot educate well without understanding the differences. Two important aspects of wisdom are needed to properly deal with that: Judgement and relative value. Judgement: male is not better than female, female not better than male. Relative value: Take the size of people. Men tend to be taller than women. But some women are taller than some men. So, it is not in 100% true. Or take sexual desire (for which testosterone is the major fuel). The man, having a much higher level of testosterone, will have more sexual desire than his female partner. But that stands not 100% of the time, and not in 100% of the couples.
The very first moment of difference takes place at conception when the genotypic sex is settled. The karyotype (with chromosomal constitution XX or XY) harbours the genetic information for the next step. There is no sexual dimorphism in the first 6 weeks of development or in the primordial gonads. The next important step is the development of gonadal sex. The default is female. Without interfering, the gonads, the genitals and the brain will ‘grow female’. However, in the presence of the Y chromosome, the primordial gonads will develop into testes and then emit hormones that will steer the genitals and the brain in the male direction. When orchestrating this development of the genitals and the brain, the sex hormones have an organizational function, whereas in later life, after the development is complete, they have an activational function, guiding sexual and reproductive behaviour. The hormonal influence results in the phenotypic sex, defined by the primary and secondary sexual characteristics of that individual. Hormones play also an important role in the formation of a person's gender identity, but they are only part of the total picture as many rearing and environmental factors add spice to that development.
Next to the mainstream, there are many sideways in this process of sexual differentiation with changes in genotypic sex, gonadal sex, phenotypic sex and/or gender identity. Inconsistencies in the biological indicators of sex, traditionally known as intersex or intersex disorders, are nowadays called ‘disorders of sex development (DSD)’. Inconsistencies in gender identity without involvement of the genital tract usually are called ‘Gender Identity Disorder (GID)’. See Chapter 26 (gender dysphoria section).
In this chapter, we deal only with the mainstream development, starting with intrauterine development, then the period between birth and puberty and then puberty.
Intrauterine development
The four relevant anatomical structures for sexuality development are the gonads, the Wolffian system, the Müllerian system and the brain. In the first 6 weeks after conception, male and female developments are the same. Becoming female is in a way the ‘default process’. Without the Y chromosome, the development will continue towards female. Then the primordial gonads will develop into female gonads (ovaries), with atrophy of the Wolffian system and development of the Müllerian system into female internal genitalia. Intrauterine female development is independent of ovarian hormones!
The default system of becoming female happens also in the brain. The foetal brain grows very fast and especially in the period between 6 and 18 weeks of pregnancy, the layout for many important and permanent structures is settled. The ‘undisturbed’ (i.e. without testicular hormones) wiring in the brain ‘grows female’, giving a strong base for the later typical female behaviour. This process is not the result of oestrogens. Although oestrogens are abundantly present in both female and male foetuses, they are so strongly bound to alpha-foetoproteins that they cannot enter the foetal brain compartment.
What about male development? With chromosomal pattern XY, a gene on the Y chromosome (SRY or Sex determining Region of the Y chromosome) causes a complex cascade of steps, bending this process towards male development. This SRY contains the code for the production of a testis-determining protein, which in turn causes the primitive gonads to become testes.
Then, three very relevant processes deserve to be mentioned, all beginning at around 6 weeks after conception:
The Leydig cells of the testes start producing hormones. Testosterone (T) is responsible for stimulation of the Wolffian system to develop into male internal genitalia. Later in the foetal life, Dihydrotestosterone (DHT) is responsible for development of the male external genitalia, and INSL3 for the testicular descent.
The Sertoli cells of the testes start producing MIS (Müllerian Inhibiting Substance, also called AMH or anti-Müllerian Hormone), by which the Müllerian tubes are suppressed and disappear, preventing the development of female genitalia.
The foetal brain becomes bathed in these two hormones T and MIS, by which the wiring in the brain ‘grows male’.
This supposed ‘dimorphic wiring’ can be seen at a macroscopic level in some brain areas. At 26 weeks of pregnancy, the corpus callosum (connecting the left and the right side of the brain) is bigger in the female foetus. The sexual dimorphic nucleus of the preoptic area (SDN-POA) of the amygdala (responsible for sexual behaviour) is in the human male twice as big as in the female.
As the construction of human beings is not like in a factory assembly line, there is much variety in intrauterine development. We know for instance about the variety in intrauterine exposure to testosterone. This shows in later life in the 2D/4D ratio (the difference between the length of the second and that of the fourth finger). A higher 2D/4D ratio is an expression of lower intrauterine T-exposition. So, females have a higher 2D/4D ratio than males. Women with higher 2D/4D ratios have more verbal skills, whereas women with lower ratios have a better sense of spatial direction. On such basis, many relations are found with toy preference, personality characteristics, sexual orientation and cognitive profile (spatial, verbal and mathematical abilities). Males generally outperform females on math and spatial tasks, whereas women outperform males on verbal fluency and fine motor skills.
As mentioned earlier, talking sex differences is a sensitive topic. In stark contrast to the differences model stands the gender similarities hypothesis. This states that males and females are alike on most – but not all – psychological variables. With her meta-analyses of research on gender differences, Janet Hyde supported this gender similarities hypothesis with as few notable exceptions some motor behaviours and some aspects of sexuality, which show large gender differences and aggression showing a gender difference moderate in magnitude. What is the reason behind those differences? They are the result of thousands of generations of evolution. All geared to preservation of the species. After all that is what we have to do and what nature dictates us. This chapter concludes with a small hint in that direction. Several times a day, the male foetus has erections (from 26 weeks of pregnancy), preparing him for his evolutionary task of reproduction. Although not yet shown in ultrasound examination, the female foetus most probably will have the corresponding perivaginal hypercirculation, preparing her as well for her reproductive future.
