4. Eggs Grow Up Slow
As well as being much larger than the other cells in the female body, egg cells also grow a lot slower. By that we mean, they take a long time to mature and be released from the ovaries. Other cells in the body mature and move around much faster, but eggs often spend years in a half-matured state in the ovaries before they’re released during ovulation.
5. They’re Super Delicate
The eggs in the female body are super fragile, which makes things much harder for the scientists involved in attempting to freeze them for later use. They can’t just freeze them, because then they would shatter and break. Instead they use a process called vitrification, which basically causes the outer layer of the eggs to harden, essentially halting them from decaying in an ice container of their own making.
6. Eggs Age Really Fast
You probably already know this, but that doesn’t make it any less amazing. When women are young, they have lots of healthy eggs. Looking at the numbers, around 90% of the eggs they have are viable and would produce children in the right circumstances. However, once a woman is 41, that number is down to 10%, which explains why so many women are choosing to opt for egg freezing to give them more time to find the man of their dreams.
