Male Reproductive Flashcards
Testes contain
Seminiferous tubules Interstitial cells( of leydig)
Sperm produced and nourished
Produced in the seminiferous tubules and nourished by the Sertoli cells
What does the interstitial cells of leydig do?
Secrete testosterone and other male sex hormones -androgens
Pathway of the sperm
SEVE (n) UP
- Siminiferous tubules (produced)
- Epididymis(stored and gain motility till ejaculation)
- Vas deferus
4 . Ejaculatory duct - Urethra
- Penis and out
When Sperm go through the path way they are mixed with…. which is produced by….
Mixed with Seminal fluid which is produced by seminal glands, prostrate gland, and bulbourethral gland
Seminal vesicles
Contribute fructose to Boris’s the sperm and give the fluid mild alkaline properties for sperm to survive in acidity of femal reproductive track.
Sperm structure
Head, mid piece and flagellum
Sperm head
Contains genetic material and is covered with an acrosome- modified golgi apprautus that contains enzymes that help the sperm fuse to and penetrate the ovum
Sperm mid piece
Generates ATP from fructose and contains many mitochondria
Flagellum
Promotes motility
In FSH stimulates
Sertoli cells and trigger spermatogenesis
LH causes
Interstitial cells to produce testosterone
Vas deferens
Surrounded by muscle that raises and lowers the gestures to maintain constant temp suitable for speed production
