1. Sex Chromosomes Gonads (reproduction) Hormones
External genitalia (penis, vagina)
Internal organs (ovaries, seminal vesicle)
Secondary sex characteristics (breasts, hair)

3. Sexual Organ Development
Undifferentiated gonads until week 6
Mullerian system
Turns into fallopian tubes, uterus, vagina if no anti-Mullerian hormone present
Wolffian system
Turns into vas deferens, seminal vesicles if androgens (testosterone and dihydrotestosterone) present

5. Sex Development Hormones present in the womb determine:
Internal reproductive organs (ovaries or testes)
External genitalia (vagina or penis)
Brain organization

6. Intersexual
Congenital Adrenal Hyperplasia: XX w/androgens, ambiguous gen.
Testosterone biosynthetic defects: XY no d.test., ext. XX genitalia
Persistent Mullerian duct syndrome: XY w/o anti-Mull = both int
Turner’s syndrome: XO = no testes or ovaries, XX int & ext
Androgen insensitivity syndrome: XY w/int. testes, ext. XX gen.
Gonadal dysgenesis: XY w/o androgens= XY ducts, XX genitalia
Micropenis: XY w/o 2nd androgen stage; testos at puberty can fix
Sry gene translocation: XX males, sry gene moves to X chromo.
Partial androgen insensitivity syndrome: XY w/ambiguous genitalia
5-Alpha reductase deficiency: XY testos. dis.=XY body, XX gen
Klinefelter syndrome: XXY = small penis/testes, low andro, breasts
Timing defect: XY w/ambiguous external genitalia

10. Sexual Attraction Automatic NS reaction Sexual orientation and:
Brain: hypothalamus, rams
Genetics: 52% Id twins, 22% fraternal, 11% adopted; region of x chromosome related to increased sexuality focused on males
Womb hormones: stress, rats mounting, multiple boys

11. Normal Sexual Response

Phase Two: Plateau
Phase Three: Orgasm
Phase Four: Resolution
Refractory period
