With more FSH, the odds of two eggs being released per cycle — one from each ovary — may increase, the researchers hypothesized.
Women with this variant may produce average levels of FSH, but have ovaries that are more sensitive to the hormone, triggering the release of two oocytes per month.
What causes Hyperovulation?
There are 4 common causes of why hyperovulation occurs: Genetics. It is common that fraternal twins run in the family on the mother’s side. This is due to the fact that some women are prone to hyperovulation.
Can both ovaries release an egg at the same time?
Only one ovulation can happen per cycle. You can, however, ovulate two (or more) eggs at the same time. But having two separate eggs released at different times within the same cycle doesn’t happen. Once you have ovulated, your empty follicle turns into something called a corpus luteum.
How common is it to release two eggs during ovulation?
A woman should not ovulate more than once during each cycle. Multiple ovulation is another phenomenon that can occur and is when two or more eggs are released in a single cycle. The eggs are released during one 24 hour period and are responsible for the birth of fraternal twins.
What causes ovaries to release two eggs?
As the follicles develop, they produce the hormone oestrogen. Once the egg has been released at ovulation, the empty follicle that is left in the ovary is called the corpus luteum. This then releases the hormones progesterone (in a higher amount) and oestrogen (in a lower amount).
