1. It’s the biggest cell in your body
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 impressive huh?
2. You’re born with all of your eggs in two baskets
Every woman is born with a set of eggs in her ovaries opposed to men who produce new sperm every 90 days. You can have as many as 7 million eggs in your ovaries when you are born.
3. Eggs decline over time
Although you are born with millions of eggs they will diminish over time so you end up with around 700,000 by the time you hit puberty. Each month you continue to lose eggs, at the point of menopause you will have approximately less than 1000 eggs remaining. Opposed to common misconception neither pregnancy nor hormonal contraception slows the monthly recruitment and loss of eggs down.
4. You release an egg every cycle
For most women the body initiates ovulation every cycle, which is when you have a positive LH test – it indicates your body is getting ready for ovulation. But 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.
Women who take hormonal contraception do not release an egg every cycle, as it inhibits ovulation. This is how pregnancy is prevented – if there is no egg to meet the sperm you cannot get pregnant. A regular cycle without ovulation is known as an anovulatory cycle.
5. An egg has a short lifespan after ovulation
Once released, an egg can only be fertilised over the next 12-24 hours. Sperm, on the other hand, can live up to 5 days if the sperm encounters the right environment. Natural Cycles takes these factors into account when calculating your fertile days.
