Q

what happens in pubertal development

A

➜Hypothalamus synthesizes and releases gonadotropin-releasing hormone (GnRH), ➜which then triggers the anterior pituitary to release follicle-stimulating hormone (FSH) and luteinizing hormone (LH)

17
Q

give 3 roles of androgen

A

✅muscular development,
✅physical growth
✅increase in sebaceous gland secretions that cause typical acne in both boys and girls during adolescence

18
Q

when is androgen low in males

A

low in males until puberty (ages 12 -14 years)

19
Q

what happens when androgen rises in males

5

A
  1. pubertal changes: ✅testes ✅scrotum ✅penis ✅prostate ✅seminal vesicles
  2. the appearance of male pubic, axillary, and facial hair
  3. laryngeal enlargement with its accompanying voice change
  4. maturation of spermatozoa
  5. (adrenarche)
20
Q

what happens when androgen rises in females

A

testosterone influences
✅enlargement of the labia majora and clitoris
✅formation of axillary and pubic hair.

21
Q
