As a fertility specialist, I can provide you with information on the menstrual cycle and egg release. Typically, a woman is born with around two million immature eggs, and by the time she reaches puberty, this number has reduced to about 300,000 to 400,000. However, not all of these will be released during her reproductive years. Throughout her reproductive life, a woman will have a menstrual cycle approximately every 28 days, although this can vary from woman to woman. In a natural menstrual cycle, one egg is released from one of the ovaries during the cycle, typically around the 14th day. This is known as ovulation. The egg then travels through the fallopian tube where it may be fertilized by sperm. In exceptional cases, a woman may release two eggs during one cycle, which can result in fraternal, or non-identical, twins. This is because each egg can be fertilized separately by different sperm. To summarize, while a woman is born with a large number of eggs, she typically releases one egg per menstrual cycle. However, the total number of eggs released over a woman's reproductive life is much less than the initial count due to the many cycles where no egg is released or the egg is not fertilized. read more >>

In all, a healthy female body will release these eggs over a period of 30 or so years. In exceptional cases, 2 eggs may be released at one cycle, that is how twins are born. During each cycle, one egg is released from the ovaries. It waits in the Fallopian tubes for fertilization by a sperm.read more >>
