Testis: sperm production

Epididymis: sperm maturation

Vas Deferens: sperm transport

Prostate gland: alkaline secretion

for semen

Seminal vesicle: fructose,

prostaglandins for semen

Bulbourethral gland: mucoid fluid

for semen

Penis: erectile organ

Urethra: exit tube for semen

Scrotum: suspends testes

Sperm FormationSperm FormationSite of sperm

production within testis

Contains enzymes for digesting

through the egg’s protective coat For movement

Contains chromosomes

Has mitochondria for energy release

SystemSystem

Ovary: egg production

Fallopian tube: egg transport, site of

fertilization

Uterus: site of fetal development

Vagina: birth canal, exit for menstrual flow, site of sexual

intercourse

Clitoris: erectile organ

immature egg

Ovarian CycleOvarian Cycle

1. Primary follicles containoocyte and begin producingthe sex hormone estrogen

Stimulates Pituitary to

release FSH, LHFollicle Stimulating Hormone:

development of follicle, containing egg

Luteinizing Hormone: controls

ovulation, development of corpus luteum

Estrogen: produced in ovary, stimulates

thickening and vascularization of

uterine lining

Female sex characteristics

Progesterone: produced in ovary,

stimulates increased thickening of uterine

lining

Estrogen and Progesterone exert negative feedback

on hypothalamus and pituitary

egg

Implantation: embryo attaches to uterine lining
