When everything seems to be going against you, remember that the airplane takes off against the wind, not with it. - Henry Ford

A woman’s eggs may continue to form throughout her life, rather than being a limited supply, as previously thought.

While most of us know the basics of our reproductive system, there are a lot of details we might not quite be up to speed on. Not everyone goes to school for almost a decade to learn all the details of a fallopian tube :)

I spent a lot of time studying gynecology and obstetrics, and years of experience have taught me even more about the reproductive system – including how surprising it can be.

To help us better understand our bodies, I’m sharing these facts you might not know about your eggs:

  1. Women may make new eggs for their whole lives, instead of having a limited supply at birth that mature over time. New research shows a type of stem-cell in ovaries that may demonstrate new eggs are continually formed.

  2. A human egg is one of the biggest cells in a woman’s body, about the size of a grain of sand. You can actually see it with the naked eye. It’s about four times bigger than a skin cell, and about 16 times bigger than sperm.

  3. For an egg to start maturing, it takes about 150 days from the signal to mature to release from the ovary. About 12 eggs are maturing at any one given time.

  4. An egg only “lives” in a fallopian tube for up to 24 hours. If it is not fertilized, it dissolves.

  5. A woman’s eggs actually choose what sperm (if any) they are fertilized by. Eggs give preference to sperm with intact DNA, and may actually trap the sperm to the egg’s surface.

  6. Multiple ovulation, or releasing two or more mature eggs within one period, is more common than you think. About ten percent of the time this happens – so most women have two eggs released about once a year.

Knowledge is power, and the more you learn about your reproductive system, the more you can be empowered to make decisions to build a family. If you’re looking to have a little one but aren’t sure why it’s not happening, make an appointment today!
