Whether you’re planning a pregnancy or tracking your fertility, understanding when you ovulate is key. This week we’ve gathered a couple of cool facts around ovulation that maybe you weren’t aware of. Find out below!
1. The female egg cell is the biggest cell!
Most cells in our bodies cannot be seen without a microscope, but the female egg cell is big enough to be visible to the naked eye. Pretty cool!
We are born with 1-2 million immature eggs (follicles) in our ovaries. Once a woman reaches puberty roughly 500 of these will mature into an egg cell that can be fertilized throughout our lifetime.
3. The egg cell only lives 12-24 hours
Once released, an egg can only be fertilized over the next 12-24 hours. Sperm, on the other hand, can live up to 5 days if the sperm encounters the right environment.
4. Normally only 1 egg is released each ovulation.
However, some women have the potential to release two eggs during one cycle, one per ovary, which is how fraternal twins are made! This is only possible within a 24 hour period. Afterwards, ovulation is prevented by the high progesterone values in your body, which is what Natural Cycles detects in your temperature (rise of 0.2-0.45 °C).
We see in our Cyclers’ data that around 5% of the cycles are in fact anovulatory – meaning that no ovulation has occurred. This is completely normal and nothing to worry about. The bleeding that follows is then due to the estrogen rising, rather than the progesterone decreasing, and is thus not exactly the same as a normal menstruation.
This was all for now Cyclers!
