2 Personal Identity Gender Attraction Pheromones Body Image Eating Disorders
3 Gender Identity Sex differences = biological Gender differences = thinking
4 Sexual differentiation How identify sexually What call self (male-female)
5 Sexual differentiation Sexual differentiation begins with chromosomes Female = XX chromosome Males = XY
6 Sexual differentiation Prenatal Start with same anatomy Müllerian ducts Lead to female internals Wolffian ducts Lead to male internals
7 Sexual differentiation Male (XY) Y Chromosome SRY (sex-determining region) Causing primitive gonads to become testes
8 Sexual differentiation Male (XY) Testes Sperm-producing organs Produce androgens (male hormone)
9 Sexual differentiation Male (XY) Wolffian ducts develop into: seminal vesicles store semen
10 Sexual differentiation Male (XY) Wolffian ducts develop into: seminal vesicles store semen vas deferens duct from testes into penis
11 Sexual differentiation Male (XY) Müllerian inhibiting hormone Peptide hormone Müllerian ducts degenerate
12 Sexual differentiation Male (XY) Testosterone Development of penis & scrotum
13 Sexual differentiation Females (XX) More estrogen than androgens Primitive gonads become ovaries (egg-producing organs)
14 Sexual differentiation Females (XX) Wolffian ducts degenerate Müllerian ducts develop Estrogen
15 Sexual differentiation Steroid Hormones four carbon rings derived from cholesterol
16 Sexual differentiation Steroid Hormones 3 effects: 1. bind to chromosomes activate or inactivate genes 2. bind to membrane receptors like protein or peptide hormones
17 Sexual differentiation Steroid Hormones 3 effects: 3. enter cells activate proteins in cytoplasm
18 Sexual differentiation Steroid Hormones Androgens and Estrogens Not a specific chemical itself Androgens promote masculine features (hair) estrogens promote female features (breasts)
19 Sexual differentiation Steroid Hormones Testosterone most widely known androgen
20 Sexual differentiation Steroid Hormones Estradiol most prominent type of estrogen higher levels in women
21 Sexual differentiation Steroid Hormones Progesterone Predominantly female Prepares uterus implantation Maintains pregnancy
22 Sexual differentiation Steroid Hormones Organizing effects mostly during critical stage determine develop as male or female
23 Sexual differentiation Steroid Hormones Activating effects Temporary Only when hormone present Can occur at any time in life
24 Sexual differentiation Steroid Hormones Sensitive period When event has long-lasting effect Testosterone impacts external genitalia in 3 rd - 4 th month of pregnancy
25 Sexual differentiation In Hypothalamus Sexually dimorphic nucleus Part of medial preoptic hypothalamus Larger in male than female Linked to male sexual behavior
26 Sexual differentiation In Hypothalamus Females can generate cyclic pattern of hormone release Males can t
27 Sexual differentiation Alpha-fetoprotein Protein that binds with estrogen Present in early sensitive period Prevents females being masculinized by their own estrogen
28 Sexual differentiation Childhood Behavior 3-8 months old Show preference for toys Girls look at dolls more Boys look at dolls & trucks equally
29 Sexual differentiation Childhood Behavior Male monkeys lay with trucks and balls more Female monkeys play with dolls
30 Sexual differentiation Childhood Behavior Female monkeys prenatal injections of testosterone After born, play more like boys
31 Sexual differentiation Activating Effects of Hormones Change behav. by enhancing $ Testosterone need for male sexual arousal Estrogens increase sensitivity of pudendal nerve
32 Sexual differentiation Brain (rat studies) Low concentrations of dopamine facilitate penile erection sexually receptive postures in female
33 Sexual differentiation Brain (rat studies) High concentrations of dopamine orgasm
34 Sexual differentiation Brain (rat studies) Males prefer cage where previously had sex Female rats find sex reinforcing only if they get to decide when it occurs -- how know?
35 Sexual differentiation Humans High Testosterone seek more sexual partners even after marry or have longterm relationship
36 Sexual differentiation Humans Low Testosterone decrease sexual activity
37 Sexual differentiation Humans Testosterone levels don t change after marriage Low T more likely to marry
38 Sexual differentiation Humans Single women high T Long-term partner have low T either homosexual or heterosexual
39 Impotence Men Inability to have erection not usually caused by low T Treated by increasing blood circulation in penis & hypothalamus
40 Gender Identity Intersexes Male & female characteristics
41 Intersexes Hermaphrodites Genitals-genetic sex mismatch Some normal testicular tissue plus ovarian tissue
42 Intersexes Congenital adrenal hyperplasia Overdeveloped adrenals Excess release of testosterone
43 Intersexes Congenital adrenal hyperplasia In genetic males extra testosterone little effect
44 Intersexes Congenital adrenal hyperplasia In genetic females Masculine physical char. clitoris may resemble penis Treated different by teachers
45 Intersexes Congenital adrenal hyperplasia In genetic females Differ in childhood interests More interested in rough sports More aggressive as adults Less interested in infants
46 Intersexes Congenital adrenal hyperplasia Create or lengthened vagina Significant sexual difficulties No romantic attraction to men Little or no interest in sex Lack of orgasm
47 Intersexes Testicular Feminization Androgen insensitivity Not bind to genes in nucleus Genetic male Appearance of female
48 Intersexes Testicular Feminization Small penis Considered female until puberty Don t menstruate
49 Intersexes Gender Assignment In 1950s Most intersexed reared as girls Surgery easier to look like girl
50 Intersexes Gender Assignment In 1950s Most developed male interests Demanded reassignment as males
51 Intersexes Gender Assignment Now Recommend honesty No bias toward female Use predominant external appearance as gender
52 Intersexes Gender Assignment Now No surgery now Change sexual orientation later?
53 Sexual Appearance Genetic males Enzyme (5 -reductase 2) converts testosterone to dihydrotestosterone
54 Sexual Appearance Genetic males Enzyme (5 -reductase 2) Inbreeding genetic disorder blocks enzyme penis not develop until puberty identified as female as birth
55 Sexual Appearance Genetic males Enzyme (5 -reductase 2) Inbreeding Boys usually want to switch to male gender identity
56 Sexual Appearance Genetic males Reassignment when teen common if: born without penis lost penis through accident
57 Personal Identity Gender roles 3-8 months old Girls look at dolls more often Boys dolls & trucks equally
58 Personal Identity Gender roles Monkeys Girl play more w/ dolls Boys play with trucks & balls
59 Personal Identity Gender roles Testosterone injected prenatal Girl monkey more masculinetype play after born
60 Personal Identity Single women Have higher testosterone levels than have long-term partner (homosexual or heterosexual)
61 Personal Identity Multiple Mates Men more interested in short-term sexual relationships with many partners
62 Personal Identity Multiple Mates Evolutionarily, both work for men: One-mate strategies Multiple-mate strategy
63 Personal Identity Multiple Mates Women have less to gain Limited number of pregnancies But can upgrade to better mate
64 Personal Identity Mate Seeking Both men & women prefer Healthy Intelligent Honest Attractive
65 Personal Identity Mate Seeking Women prefer: Good providers strongest when no $ of own Strong commitment
66 Personal Identity Mate Seeking Body odor Women prefer differ from hers immune genes dissimilar Men strongly prefer younger
67 Personal Identity Mate Seeking Differences in Jealousy Men upset by sex infidelity Women upset by emotional infidelity Evolved or Learned
68 Sexual Orientation Anatomical Differences Longer arms, legs & hands In heterosexual men In homosexual women
