1. Male Reproductive System

2. External Genitalia
Scrotum and Penis

3. Internal reproductive organs
Testes – contain highly coiled tubes called seminiferous tubules where sperm form
Epididymis –stores sperm where they gain motility
Vas deferens – tubes goign from the epididymis to the urethra
Seminal vesicles – makes 60% of volume of the semen contains mucus, amino acids and fructose.
Prostate Gland – secretes fluid that is part of the semen contains enzymes and is alkaline
Cowpers Gland – produces a clear fluid to neutralise any urine in the urethra before ejaculation

5. Seminiferous tubules Where sperm is produced through meiosis
Interstitial cells are scattered between the tubules which produce testosterone and other male hormones (androgens)

6. Scrotum
Fold of skin that allows the testes to sit away from the body as sperm production can’t happen at normal body temperature. Approximately 2 degrees C lower than body temperature.
