Testes

• seminiferous tubules

  • spermatogenesis

  • FSH (anterior pituitary)

• sertoli

  • nourish

• interstitial cells

  • testosterone

  • LH (pituitary)

• scrotum holds testes

  • below body temperature (sperm won’t produce if body temp is too high)

Epididymis

sperm matures

Vas deferens

• pathway

• vasectomy (blocking the pathway)

• seminal fluid (prostate, cowpers, seminal vesicle)

Prostate

• alkaline buffer against vagina acidity

Cowpers

• mucus buffer against urine

Seminal vesicle

• fructose for energy to swim

• prostaglandins

Urethra

• semen/urine exit

Ovary

• gonad (oogenesis)

• ovum

• estrogen/progestrogen

Fimbrae

• bring egg to oviduct

Oviduct

• fertilization (sperm + egg)

Uterus

• implantation

• myometrium muscle, endometrium

• blood vessel layer

Cervix

Vagina

• birth canal
