Science of Pregnancy Week Two: Fertility

18 Apr

Your egg, preparing for debut

Girls are born with ~1-2 million eggs in their ovaries. In adulthood, a fraction of these eggs ripen. In a typical menstrual cycle, one egg is launched each month on a great lazy river ride. It’s released from the ovary, swept up in the tendrils of the fallopian tube, and ushered by a gentle tide toward the uterus.

When you had your period last week, your body flushed out an egg that was not fertilized during that adventure. But your body is already at work preparing the next contestant.

If you are trying to conceive, your most fertile period is in this window: the week leading up to, and including, ovulation.  Check an ovulation calendar to identify when you are most likely to become pregnant.

During this time, several hormones are working like greek goddesses in your system, bestowing vital gifts to prepare your egg for its journey: protective shield, snack bags, a safe landing zone— and plenty of sperm-grabber, just in case.
