Reproductive System

sperm

what are the male gametes

oocytes/eggs

what are the female gametes

meiosis

gametes with 23 chromosomes

sperm + oocyte = zygote -> embryo -> fetus

fertilization process

testis

sperm production and testosterone secretion

epididymis

sperm maturation

vas deferens

sperm transport

urethra

urine and reproductive fluids passageway

seminal vesicle

fructose, prostaglandins

prostate gland

liquefies semen, neutralizes acidity

Bulbourethral gland

neutralizes urethra and vagina acidity
