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 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 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.
There are many things that take place in the female body, that makes the process of menstruation take place. The body seems to have a clock all its own and everything works together like a well oiled machine. There are times though when the machine is not totally in sync and hormones do not do what they should and ovulation and menstruation do not take place or one takes place and the other doesn’t irregular or non-existent periods are a clear indicator that something is wrong and you need to consult your doctor, especially if you are trying to get pregnant.
