What does Progesterone do?

Aids in implantation and gestation, Increases sex drive, and prepare the body for pregnancy.

What does Activin and Inhibin do?

Activin stimulates FSH ( Follicle-Stimulating Hormone) production, Inhibin inhibits it

What is Testosterone produced by?

Interstitial cells (or Leydig cells)

What do the Testes do?

Development of male primary/ secondary sexual development, Aids spermatogenesis, Increases sex drive, and helps maintain bone density

What is Activin and Inhibin produced by?

Nurse Cells (Sertoli cells)

What does the pineal gland produce and do?

It releases melatonin in the 3rd ventricle to aid sleep

What possible illness/ disease could pineal gland cause?

Irregular production could cause various sleep disorders
