Beginning The Journey Toward Pregnancy
First things first, making the sperm and the egg available. The sperm enters your body through sexual intercourse, and the egg is released once a month from one of your ovaries, in a process known as ovulation, into the fallopian tube where it can fuse with the sperm, in a process called fertilization.
So, the basic idea behind a successful fertilization is timing intercourse and ovulation as perfectly as you can because there’s no way to control fertilization itself.
There’s a caveat even in that. It’s not easy to find out when the ovulation is actually taking place. And unlike the sperm that can stay alive in your body for a maximum of 5 days, your unfertilized egg has a lifespan of 12 to 24 hours.
So your number of fertile days is limited to 6 days a month: 5 days leading up to your ovulation and the day after. This is known as the fertile window. But not all days are equally fertile. Fertilization, however, can happen only within a maximum of 24 hours after ovulation.
