This is an important aspect of reproduction and endocrine systems.

Typically there are two testicles within the scrotum

The testicles have very similar functions in men as ovaries do in women.

The functions of the testicles are

- Sperm production
- Male sex hormones: testosterone

Enodcrine control is from specific hormones that are produced in the anterior pituitary:

- FSH (follicle-stimulating hormone and LH (luteinizing hormone)

Testes Structure

Tunica Albuginea – A semi-hard outer membraneous shell
Seminiferous tubules – Tubules that are coiled within the tunica albuginea. Cells line this tubules that produce sperm
Epididymis – This area is where sperm is housed to mature (spermatogenesis)
Vas deferens – A tube that transports sperm

 
Cell types of the testes

1.) Sertoli cells – production of Estradiol and Inhibin
2.) Leydig cells – secrete steroids
3.) Gametes cells – contain DNA for fertilization
