Male Flashcards
(29 cards)
gonads
testes in males, ovaries in females, produce sex hormones
goands produce
testosterone in males
▪E&P in females
function of male reproductive system
make sperm, mature, and exit, male sex hormones
testes
-produce sperm + testosterone
- in seminiferous tubes
male gamete
sperm
seminiferous tubule
produce sperm & testosterone
sertoli cell
support sperm development
interstitial cell
secrete testosterone
epididymis
-where sperm matures & gets tail and move
- stored until needed
vas deferens
Conducts sperm from testes to prostate gland (connects to urethra) during ejaculation.
seminal vesicle
provides fructose and prostaglandins
fructose
source of energy for sperm cells
prostaglandins
assists sperm movement
ejaculatory duct
mixes sperm and saminal fluid
prostate gland
Basic fluid to neutralize vaginal acidity, aids sperm survival. urethra closed during ej
cowpers gland
Mucus-rich, alkaline fluid that neutralizes urethral acidity.
urethra
Conducts sperm/semen and urine out of the body.
difference between sperm and semen
Sperm are male reproductive cells, while semen is the fluid that carries and protects them.
3 main glands
seminal vesicles
prostate gland
cowpers gland
Hormonal Control in Males
Hypo releases GnRH, stimulating the pituitary to make FSH and LH
FSH in males
Promotes spermatogenesis in seminiferous tubules., produces sperm
LH in males
Stimulates interstitial cells to LH to produce testosterone.
testosterone
secondary sex characteristics (facial hair, muscle growth).
Increases sex drive & sperm production.
inhibin
Produced by Sertoli cells to regulate FSH
