Understanding Your Menstrual Cycle


When a baby girl is born she comes with a storehouse of eggs in her ovaries and she will never be able to produce anymore. When she becomes mature and begins to go through puberty, only around 15 of her 20000 eggs will make an attempt at maturation in any cycle. Follicle stimulating hormone acts as a communicator and tells the egg that it is time for its release. Every egg is enclosed in a follicle all its own, the follicles contains estrogen.

Once the estrogen starts going through the follicle it starts to stimulate the maturity of the eggs. The egg that is considered to be the most ready is then released from the ovary, the others break apart and disintegrate. A hormone called the luteinizing hormone is actually released by the estrogen, this hormone is actually the catalyst for the egg being triggered for release.

The follicle that previously encased the egg then gets transformed into what is known as the corpus luteum. The job of the corpus luteum is to strengthen the lining of a woman’s uterus for the implantation of a fertilized egg, by releasing hormones, specifically, estrogen and progesterone. The corpus luteum will usually stick around for a maximum of sixteen days. The progesterone it secretes actually prevents other eggs from being released from the ovary.

The corpus luteum along with its excretions of progesterone provides the endometrium with time to get strong so as to maintain the egg if it is fertilized. Progesterone makes the cervix secrete cervical mucus. This creates an easy stream for the sperm to go swimming to the egg. Normally when the egg does not get fertilized the work carried out by progesterone in the development of the lining of the endometrium and the corpus luteum turn out to be unnecessary therefore both start to fall apart, progesterone and estrogen are released in smaller amounts . the lining in the womb gets very weak and it naturally starts break apart. this breaking apart comes out as blood called menstruation.

If this does not happen and the egg does not get fertilized, then the corpus luteum and the lining of the womb begin to disintegrate due to the fact that progesterone and estrogen production slows down. The disintegrating corpus luteum and the lining of the womb is what comes out monthly as the menstrual flow.

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.
