Little girls are already equipped for reproduction when they are born, from the time they begin to grow in the womb, they already have a complete supply of eggs that they will be born with. However, only fifteen of those thousands of eggs though will attempt to ripen and prepare itself for fertilization in any menstrual cycle. Each egg comes enclosed in its own cocoon called a follicle. The follicles are filled with estrogen.
This estrogen starts shooting through the follicles causing the eggs to ripen. The egg that ripens first is the lucky one which is released. The other unlucky eggs will all soon dissolve. High levels of luteinizing hormones (LH) tend to be produced by the estrogen. The LH is really what pushes the release of the egg. Occasionally the ova (egg) is launched down the fallopian tube with such pressure that a few ladies may feel pain.
The follicle encasing the ova is changed to what is known as The corpus luteum which consequently begins secreting estrogen as well as progesterone that works on the lining of the womb preparing it for the implantation of an egg that has been fertilized. The corpus luteum remains behind for 12 to 16 days secreting progesterone in order to prevent other eggs from being launched. Nevertheless, there are rare cases where another egg slips by, this generally produces fraternal twin babies if both eggs get fertilized..
The corpus luteum gives the lining of a woman’s uterus all the time it will need to become stronger and because the corpus luteum is always secreting progesterone, this has the effect of making the cervix produce the kind of cervical fluid that makes it easy for sperm to swim to the egg for fertilization, if the woman has intercourse.
As you can see much takes place in a woman’s body, in order for menstruation to occur and all these thing need to occur like clockwork in order for a woman to either conceive or end up menstruating. Occasionally problems occur where hormones are not being released as they should be and it may cause problems with fertility or menstruation.
You are probably now aware after reading, how the whole process works and that there are many things in a woman’s body that need to come together to make everything work perfectly so that menstruation or fertilization of the egg takes place, in fact, the body operates like a machine where every egg, follicle and hormone knows its place and carries out its job accordingly. Occasionally though, signals get crossed and everything does not operate as it should. If you find that you have issues with the regularity of your menstrual cycle, then you should consult a doctor as this can adversely affect your ability to conceive.
