When is there more sexual interest in women
What does 5-alpha reductase do?
Converts testosterone to 5-alpha dihydrotestosterone
What activates sexual behavior in women?
Maybe testosterone but no other species exhibits that. Need more research on ovarian hormones (estrogen)
Characteristics of kleinfelter syndrome
Tall stature, some female secondary sex characteristics such as wide hips and breast growth. Show signs of a female puberty
When are females more accurately able to guess male sexual orientation?
Close to ovulation
How do hormones and sex differences play a role in health?
Many psychological disorders affect males and females at different rates
When does puberty really start?
When gonadotropins are first released in large amounts
Sex monosomie. 45 X0
Stable pattern of attraction to members of a particular sex that isn't the same as sexual behavior or fantasy and isn't purely dichotomous
What does insulin do and where is it produced?
Blood glucose produced in pancreas
What do estrogens do and where are they produced
Breast development and menarche in females produced in ovaries and testes and adrenal glands
Blood levels of LH and FSH pituitary hormones during human menstrual cycle
Higher LH than FSH
What do OAEs presumably indicate?
The influence of prenatal testosterone levels
Three steps of puberty
1.) Hypothalamus releases gonadotropin-releasing hormone (GnRH) to pituitary glad
2.) Pituitary gland releases gonadotropins
3.) Secretion of sex hormones from the glands
Gonads in AIS and 5ARD
Neither in AIS and undescended testes in 5ARD
What happens at puberty
Sexual maturation and the development of secondary sex characteristics
Premenstrual mood changes are usually severe affecting cognition and daily life
Premenstrual dysphoric disorder (PMDD)
New mothers experience feelings of depression due to rapidly changing hormonal environment
Postpartum depression (and anxiety and psychosis)
What does progesterone do and where is it produced
Preparation of uterus for implantation of fertilized egg produced in ovaries and testes and adrenal glands
What causes androgen insensitivity syndrome?
Abnormal androgen receptors disrupt normal development of the Wolffian system, though testosterone and anti-mullerian hormone are released in normal manner. Non-functional androgen receptors
What do testosterone levels correlate with?
Activation during spatial tasks
Female sexual interest stability
Not as stable as men
What do all sex hormones come from?
What do androgens do and where are they produced
male secondary sex characteristics, sexual arousal in males and females and produced in testes as well as ovaries and adrenal glands
Phenotype of turner syndrome
What does every fetus have at 6 weeks?
Both a wollfian and mullerian duct
A type of hormone that causes a defeminizing effect that prevents the mullerian system from developing
External genitalia of turner syndrome
Females preferences of males for casual sexual encounters and long term partners
Masculine men for casual and less masculine men for long term
