Answer:The sperm leave the man’s penis by ejaculation and are deposited in the vagina high up near the cervix (the opening to the womb). The sperm immediately begin swimming and some will find their way into the cervix.
The sperm then begin their long journey towards the egg. Leaving the cervix they enter the womb. Here, they swim towards the Fallopian tubes. The vagina and the womb are quite hostile environments for sperm, however, once the sperm reach the Fallopian tubes they are mainly free from the potential negative effects of the woman’s immune system. Only 1 in 14 million of the ejaculated sperm will reach the Fallopian tube, but once there the sperm should pick up chemical signals from the egg to help them find their way forward.
The sperm finally near the egg and push towards its shell (called the zona pellucida). Many sperm will bind to this shell, but only 1 sperm will be allowed to go all the way through to reach the egg inside.
Sperm can survive for a few days in the female reproductive system – hence a sperm ejaculated during intercourse on a Monday could fertilise an egg ovulated on the Tuesday or Wednesday!
