As added by P.L , SEC.10. Amended by P.L , SEC.1.

5. C. Gender identity M F
Transgender – “People who were assigned a gender, usually at birth and based on their genitals, but who feel that this is a false or incomplete description of themselves.”
Transsexual – “Transsexual people are people who desire to have, or have achieved, a different physical sex from that which they were assigned at birth”
FTM
MTF
Genderqueer – “A genderqueer person is part of a group of people who do not think that they fit into the traditional two-gender or gender-binary system.”

8. II. Hormones and sexuality
Hormones are directly involved in all aspects of sexuality: Desire, Excitement, Intimacy etc…
Testosterone
Positive relationship between testosterone levels and masturbation but not intercourse frequency
Positive relationship between testosterone levels and sexual interest among adolescents, but found that peer relationships were a more important determinant of sexual behavior.
Estrogen
Estrogen deficiency, as occurs with menopause, causes a decrease in genital vasocongestion and lubrication and atrophy of the vaginal epithelium

9. Hormones continued: Progesterone Prolactin Oxytocin Pheromones
Certain oral contraceptives that increase progesterone levels throughout the female cycle have been associated with decreased sexual interest and desire
Prolactin
Oxytocin
Pheromones

10. Neurotransmitters also play integral part
Nitric oxide
Sexual stimulation leads to NO production that in turn stimulates the release of
Guanylate cyclase converts guanosine triphosphate to cGMP and cGMP produces relaxation of the smooth muscles of the penile arteries and corpus cavernosum resulting in increased blood flow in the clitoris
Sildenafil, a drug designed to treat erectile difficulties, prolongs the action of cGMP by inhibiting the metabolism of cGMP
Epinepherine
epinephrine and norepinephrine metabolite, vanillylmandelic acid, increases prior to intercourse and continues to be elevated over baseline up to 23 hours following sexual activity

13. B. People learn to be sexual

14. IV. The female sexual response

15. Overview of the female sexual response cycle:
Physiological sexual arousal in women begins with increased clitoral length and diameter, and vasocongestion of the vagina, vulva, clitoris, uterus, and possibly the urethra.
Engorgement of the genital vascular network increases pressure inside the vaginal capillaries and results in lubrication of the epithelial surface of the vaginal wall.
Orgasm is characterized by a peak in sexual pleasure that is accompanied by rhythmic contractions of the genital and reproductive organs, cardiovascular and respiratory changes, and a release of sexual tension
The body returns to its pre-aroused state

16. A. Excitement Phase
Women are less likely than men to pick up on the physiological cues of their own sexual arousal…
Heart rate
Vasocongestion –
Clitoris begins to swell - the corpora cavernosa of the clitoris consist of a fibroelastic network and bundles of smooth muscle. Pelvic nerve stimulation results in clitoral smooth muscle relaxation and arterial smooth muscle dilation.
With sexual arousal, there is an increase in clitoral cavernosal artery inflow and an increase in clitoral intracavernous pressure that leads to tumescence and extrusion of the clitoris. \

18. B. Plateau phase
Outer third of the vagina wall becomes swollen with blood
Labia minora also become engorged with blood
Breasts become somewhat engorged, nipple erection maintained

19. C. Orgasm Orgasm – at which time the pulse rate reaches its peak
Suffusion of warmth spreads from pelvis throughout the body
Initial contraction, followed by 3 or 4 rhytmic contractions

20. D. Resolution
Body gradually returns to its unexcited state following the orgasm
Glans emerges from the foreskin and returns to its usual size within minutes
Respiration, pulse and blood pressure return to normal
Muscles relax

22. Multiple orgasms in Women
Most, if not all women have the potential for more than one orgasm
May depend on the type of sexual stimulation involved

23. In 1997, Whipple and Brash-McGreer proposed a circular sexual response pattern for women.
comprises four stages Seduction (encompassing desire), sensations (excitement and plateau), surrender (orgasm), and reflection (resolution).
pleasant and satisfying sexual experiences may have a reinforcing effect on a woman, leading to the seduction phase of the next sexual experience.

24. V. Female Sexual Dysfunction
1) Sexual desire disorders, 2) sexual arousal disorders, 3) orgasmic disorder, 4) sexual pain disorders
1999 survey found that sexual dysfunction of some form was reported more commonly among females (43%) as compared to males (31%)

26. A. Mechanisms of sexual dysfunction
Psychogenic
Relationship issues, depression, anxiety, self-esteem, body issues, personal loss, abuse, etc.
Iatrogenic
Medications, gynecologic surgery
Vascular
Cardiovascular disease, diabetes, hypertension, smoking…
Neurogenic
Spinal cord injury, disease of CNS, neurotransmitter dysfunction
Hormonal
Hypothalamatic-pituitary axis dysfunction, premature ovarian failure, androgen deficiency
Musculogenic
Hypertonic pelvic floor muscles, hypotonic pelvic floor muscles

27. B. FSD Treatment Nonphparmacologic Pharmacologic Hormone therapy
Antidepressants
The Eros Therapy

28. VI. Effects of drugs on sexuality
Dosage and timing important
