This questions doesn't really make sense. But I'll try to explain as much as I know to be relevant. A woman is born with a certain number of eggs...no more are ever created. You live your whole life with the same exact eggs that you were born with. When a woman is in ovulation the eggs become more vulnerable for fertilization, so if you are trying to get pregnant, when you are ovulating is the best time. But if you are trying to revent pregnancy it would be best to avoid intercourse during ovulation. It usually only lasts a few days.
Usually, only one egg is released; however, two can be realeased at once during ovulation.
No eggs are released during a period.Menstruation occurs around two weeks after ovulation and is the process of uterine lining breaking down. Eggs are released during ovulation, usually only one but sometimes multiple.
Eggs are released during ovulation, which may or may not occur during intercourse. Normally only one egg is released during ovulation, but some women release more than one from time to time, which is the origin of spontaneous fraternal multiple births.
Ovulation is the term used when eggs are released from one of the ovaries.
Menstruation is the best evidence that ovulation is occurring.
When a pig ovulates, it releases two eggs. This is because of the forked uterine canal that pigs have compared to one egg by humans.
normally one egg is released from one ovary during ovulation. That egg releases hormones that signal the other eggs to stay put. Sometimes two eggs release at the same time (usually one from each ovary) and that's how you get twins. Some fertility drugs tell the ovary to release more than one egg, which is why fertility drugs often lead to multiple births.
Chimpanzees don't lay eggs, they have live young and give birth to one at a time. Twins can happen, but are rare.
Ovulation is defined as the release of the egg; they happen simultaneously as they are one and the same.
There are a couple of ways that multiples are conceived: 1) Multiple eggs are released or there is more than one ovulation. Two eggs are fertilized and you have fraternal twins. This can happen with or without fertility drugs. 2) One egg is fertilized and then splits in two resulting in identical twins. This can happen with or without fertility drugs. 3) In cases of in vitro fertilization (IVF), 3 or more fertilized eggs are put back into the uterus. The rationale is that not all of these will implant, though sometimes they do.
You have twins
It is different for every person and every cycle, sometimes one, sometimes several, this is how fraternal twins are produced, more than one egg gets fertilized and implants and starts growing.
