an ovum mature oocyte after meiosis division
The ovum (egg) is released before a period and it travels down the Fallopian tube into the womb. A few days later, if it has not been fertilised by a sperm, then the womb will shed its lining, and will also shed the ovum (egg). This shedding of the womb is a woman's period.
Yes, because the mature ovum (egg) is released 14 days before the next period.
If your ovum is not fertilised by a sperm, it will pass through the fallopian tube and disintegrate in the womb after 12-48 hours. Around 10 days later, the lining of the womb sloughs off and you have your period.
Yes, while you probably don't ovulate that early in your cycle, sperm can live for 5 days while waiting for the ripe ovum.
The oogenesis of a rat is the period of time in a female when the ovum is immature. The process begins with oocytogenesis and ends with a mature ovum.
every women who is matured has ovary to produce ovum. This ovum matures and sheds off from ovary for union with sperms it does not unite with sperm then it is removed from female body in every month in the form of menses. this requires 28 days to complete in normal course.
Fertilization of the ovum by a sperm cell occurs in the third of the Fallopian tube nearest each ovary. Interesting fact: The fallopian is about the diameter of a pencil. The ovum is about the size of a period on a page.
Gestation
The purpose of menstruation (period) is to clean out the lining of the uterus (baby bed). Afterwards, another ovum (egg) drops down and is ready for fertilization to start pregnancy. If there is no pregnancy, then 28 days (average) later, the cycle starts again with the next period.
From the time when the bull ejaculates inside the cow to when the sperm from the bull merges into the ovum of the cow, which typically occurs 2 to 3 days after the cow has gone out of heat.
