9 Scientifically Proven Facts About Female Eggs You Must Know

Most of us don’t know too much about the female eggs – it’s a shame that we know more facts about the eggs in a carton than these eggs. Here are some interesting facts about the female eggs:

  1. They are made quite early.  The female reproductive system makes the eggs about nine weeks after conception. Then, the ovary produces about 7 million oocytes (female gametocytes involved in reproduction) in only 5 months. Until birth, most of the immature egg cells die off.
  1. The eggs are huge!  If you compare the egg cells with other body cells, you will see that there is a huge difference in size. The female eggs have a diameter of 100 microns, and are thick as a strand of hair.
  1. They are precious.  A woman ovulates about 400-500 eggs during her lifetime, making the eggs more precious and rarer than sperm. A single ejaculation releases more sperms than a woman produces eggs in her lifetime! That’s why there are egg donors that cost hundreds of dollars for just one egg.
  1. The eggs have extended adolescence.  The egg cells grow-up slow – they need years to reach adolescence, and mature right before ovulation.
  1. They are quite fragile.  As the female eggs are fragile, a technique called vitrification can harden their outer layer and make them more resilient.

  1. Female eggs age fast.  A young woman has healthier eggs than an older one, which is normal. But, a 24-year old woman may have 90% viable eggs, and a 40-year old will have just about 10%. This is the main why women often extract and freeze their eggs.
  1. The eggs are monogamous.  The eggs allow entrance to only a single sperm. They have a special “organelle” that releases proteins and enzymes to ensure that another sperm doesn’t get in.
  1. Eggs are the baby-making machine!  Sperm was always believed to be the main reproductive and life-containing cell. However, it’s actually the female eggs who have that power. They also pass half the genes to the baby.
  1. Egg-donation: it’s not as fun as it looks.  Egg-donation is a complete medical procedure, which is a lot tougher than sperm donation. The donor first gets a hormonal injection so they create a single egg. After the egg is produced, a doctor inserts a catheter inside the birth canal and sucks out the fluid from the follicle.
