Puberty - period of maturation during which sexual organs mature
-menarche is the 1st menstruation > for females, which is the production of ova
-spermarche=1st ejaculation for males >ejaculation signifies the sperm production
gonads - paired sex glands in M/F (testes/ovaries) which produce sex hormones
and gametes
androgens - male sex hormones (Testosterone)
-have female hormones but produce more male
-organize immature reproductive system which is suppressed until pubertal
development begins (hormonal changes begin in hypothalamus) -beneath cortex
estrogen - female sex hormones(estradiol)
-have male hormones but produce more female
,HPA axis - ***CALLED THE HYPOTHALAMUS PITURITARY ADRENAL axis
-the hypothalamus stimulates the pituritary gland >>>>>which stimulates the
adrenal glands>>>>>which releases androgens (typically
testosterone)>>>feedback loop
- triggers pituitary gland to trigger release of androgens in adrenal glands
-pituitary glands responds to signals from hypothalamus
-hypothalamus increases production of gonadotropins (folic stimulating
hormonic ) and (lureinzeing hormones)
****there is a set level to stop producing androgens when they have enough
made

has growth of a cm or so taller than the previous generation
-stopped in developing nations
a change occurring several generations
-onset of puberty becoming earlier
-biological limit
-puberty is unlikely to get younger in developed nations
earlymaturation - -early maturing of women will target unwanted sexual attention
from others
-reaching puberty early may be associated with depression, low self esteem poor
body image deliquincy, aggression, and early sexual behavior

**increase adolescent vulnerability to stress
body image - perception of one's body shape and size
