What is the function of the female gonads?
They produce the egg cells and the female sex hormones.
The principal male sex hormone is __________, which regulates the production of sex cells and the development of male characteristics.
testosterone
The ovaries produce two hormones, _______ and _______, which regulate the release of the egg cells and the development of female traits.
estrogen
progesterone
The _____ are two oval-shaped organs that produce sperm cells.
testes
The testes are located in a protective sac called _____
scrotum
Is the loose pouchlike sac behind the penis. It keeps the testes a few degrees cooler than the rest of the body. This is important because sperm cells cannot survive high temperature.

sperm duct or vas deferens
The sperm cells pass from the sperm ducts through the ______.
urethra.

semen.
Is it true that in addition to carrying semen, the urethra carries urine?
True.
Urethra carries one fluid at a time, is this true?

Where is the urethra located?

Ovulation Phase
This usually happens once a month, typically during the 14th day of the menstrual cycle. It can last from 16 to 32 hours.
Ovulation
This a menstrual cycle phase starts after ovulation, cells in the ovary, called corpus luteum, release progesterone and estrogen.

- Do not smoke. Smoking decreases blood circulation and may cause erectile dysfunction.
- Have a regular examination of the prostate gland and the testicles.
