When we reach the age of 12-15 we boys start to notice changes in our body. Our reproductive organs get larger. Today, I will be reflecting on what I had learnt about the male reproductive system.
WeWe will start with the testes. The male reproductive system contains two ovules of testes. They produces sperms. The epididymis stores inactive sperms before they are released into the sperm duct. The sperm duct loops over the ureter and opens into the urethra. The Prostate glands, Cowper glands and seminal vesicles releases fluids that contains nutrients and mixes them with the sperms before it is released from the urethra in the penis. This fluid actually activates the sperms. The mixture of sperms and the fluid is called semen.
Anatomy of a Sperm
The head of the sperm contains the nucleus, cell membrane and the acrosome. The acrosome is important as it contains enzymes to break through the cell wall of the female egg cell. The mitochondria produces energy for the sperm to swim to swim towards the egg to fertilise it. The tail or also known as flagellum allows the sperm to swim to the egg cell.
