Ovulation depends on a delicate balance of hormones. In order for ovarian follicles to begin developing into mature ova, follicle stimulating hormone (FSH) must be released from the pituitary gland.
When a woman is pregnant, a hormone released by the corpus luteum or the placenta called progesterone prevents FSH release from the pituitary, so no further follicles are stimulated to mature, so no eggs are released.
Yes. That's why it is better to not get pregnant as an older woman. Men produce sperm every day.
Yes, it does gradually slow down as you get older. But each period you have is the system clean out and getting ready for the "new eggs".

In girls just starting menstruation and women undergoing menopause it can be (and usually is) much more irregular. Note: the average is for the release of ONE egg and there are TWO ovaries.
Why do you think millions of sperm are released to fertilize one egg?
Releasing millions of sperm increases the likelihood of successful fertilization by increasing the chances of one sperm reaching and penetrating the egg. This strategy helps ensure that at least one healthy sperm will successfully fertilize the egg.
Is many sperm feritize one egg?
No, only one sperm can fertilizes one ovum. In women only one egg cell or ovum is produced per overy. And in men about thousands sperms are produced. But when only the strongest sperm reach near the ovum membrane then it hit the membrane and enter into the ovum then one enzyme is secreted and this seals the membrane to restrict other sperms. This system is called the 'lock and key system'.
Which one of the follopion tubes release the egg?
It depends on the person. With most women the ovaries may alternate with one releasing an egg one month and then the other releasing an egg the next. Women are born with all of their eggs and it depends on when each egg is ready and hormones. However, some women only release from one ovary because something is wrong with the other.
Why men have lots of sperm and woman have one egg?
