- Male sex organs and hormonal control
- Testes
- site of sperm production
- formed by meiosis in the seminiferous tubules
- these form coiled tubes which connect to the sperm duct
- formed by meiosis in the seminiferous tubules
- manufacture of the sex hormone testosterone
- produced by interstitial cells
- located in the tissue between seminiferous tubules
- passes directly into bloodstream
- produced by interstitial cells
- sperm are motile; they move through the uterus and along oviducts where they may meet an egg
- fertilisation is dependant on motility of sperm which brings gametes together
- requires a fluid medium and a source of energy
- fertilisation is dependant on motility of sperm which brings gametes together
- site of sperm production
- Accessory Glands
- prostate gland
- secretes a thin lubricating liquid containing enzymes
- maintains fluid medium at the optimum viscosity for sperm motility
- secretes a thin lubricating liquid containing enzymes
- seminal vesicles
- secretes a viscous liquid rich in fructose and prostaglandins
- prostaglandins - hormone-like compounds which stimulate contractions of the female reproductive tract
- the movements help sperm to reach the oviduct at a much faster rate than could be achieved by swimming
- fructose - sugar which provides sperm with energy needed for motility following ***********
