Of the hundreds of millions of sperm cells that begin the journey up the Fallopian tube, only a few hardy travellers will ever reach their destination. Sperm cells are extremely efficient at swimming against a current and travel long distances, through difficult terrain, to reach an egg to fertilise it, according to a new study.
How long sperm live… The details of their journey… The variables for survival! Today, we know that this is not the case, and that sperm health is just as important as regular, predictable ovulation and overall menstrual health.
Every month, the female ovulates one mature egg from one of her ovaries. Here, it will begin to move slowly down the tube towards the womb uterus.
