What do the seminal vesicles produce to add to semen?

|
What 3 hormones are involved on sperm production?
|
.Follicle Stimulating Hormone (FSH)
.Interstitial Cell Stimulating Hormone (ICSH) / Luteinising Hormone (LH) .Testosterone |
|
|
Outline the steps in sperm production.
|
.Pituitary secretes FSH and LH. These hormones stimulate sperm and testosterone production.
.Testosterone levels continue to increase until it inhibits FSH and LH production. .Drop in FSH and LH=drop in testosterone. .As testosterone drops FSH and LH are secreted again, and so on. This is called negative feedback. |
