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".

Why do some animals fertilize only one egg at a time while other animals fertilize multiple eggs?
It has something to do with the fecundity of the organism. Some organisms release only one egg at a time, so only one egg gets to be fertilized. Smae goes with the animals that release multiple eggs at once, the eggs can be fertilized all at the same time.
Does both ovaries release eggs each month?
Yes, they do.
How often do egg cells mature and leave the ovary?
It varies somewhat but it works out to be, on average, about every 28 days. There is variation between women and even from cycle to cycle for individual women. 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?
Women don't have only one egg or ovum, but the natural lifespan of a woman's fertility is limited. If your thinking was correct a woman couldn't have more than one child or twins. It is illogical to think that women only have one egg.
How can a women release a fertile egg after been sterilized?
Female sterilization normally involves cutting or tying the fallopian tube, limiting access to the egg by the sperm. A women still ovulates every month. Ovulation is the release of an egg. A fertilized egg is one that has allowed the sperm to penetrate.
Can 2 women and a male produce a healthy baby?
Only one of those women can be a part of the baby. One egg+one sperm=1baby
When a women ovulates how many eggs release?
When a woman ovulates, usually just one egg is released.
How many eggs do human females usually release each month?
Most women only release one egg, but obviously sometimes two, three or even more are released, hence twins, triplets and so on. If a woman is receiving drugs to stimulate egg production prior to egg harvesting for IVF she may release many eggs.
How many eggs do human females usually release each menstrual cycle?
Human females typically release one egg per menstrual cycle during ovulation. On rare occasions, some women may release more than one egg, leading to fraternal twins or multiple births.
Why do some animals fertilize only one egg at a time while other animals fertilize multiple eggs?

When one woman's egg is transplanted into another women who's genes will the embryo have?
the genes are in the egg. so the women who gave the egg will share the genes of the baby
Do you ovulate first then release the egg?
Ovulation is defined as the release of the egg; they happen simultaneously as they are one and the same.
How many days between women realising each egg cell during menstrual cycle?
A female will only ovulate once per menstrual cycle, typically this occurs 12-16 days before menstruation. During the 24 hours of ovulation it is possible to release multiple eggs, but most commonly only one egg is released per cycle.
What is made by meiosis in women?
egg,one via oogenesis
