Q

Seminal Vesicles

A

Base of bladder where Vas deferens enters the Prostate
Secreted fructose(food for sperm), Prostaglandins(hormone which allows the female cervix to allow Sperm in) and sodium bicarbonate(neutralize the acidic vagina)

23
Q

Prostate Gland

A

Squeeze & Push, force behind ejaculation
Secretes- Sodium Bicarbonate(neutralize acidic vagina), Milky fluid (to aid sperm motility)

24
