Indicate which of the following are true regarding the uterus.

Follicular phase
Maturation of ovarian follicles mediated by FSH
Epididymis
Promotes maturation of the sperm cells and stores sperm cells
Penis
Richly supplied with sensory nerve endings; conveys semen and urine outside of the body
Bulbo-urethral gland
Secretes a fluid that lubricates the end of the penis

Why is it important to maintain testes temperature at values lower than body temperature?
Sperm viability requires the lower temperature.
Ovulation
Surge in concentration of LH
The scrotum is lined by smooth muscles. Additionally the cremaster muscle is attached to the testes. Why are these muscles important?
They help regulate the testes temperature for optimal sperm production.
