Ovulation of the egg. Part 1

Fertility means ovulation of the egg!

Ovulation ends with the release of the egg from the follicle into the fallopian tube. In fact it is more a beginning because the egg travels through the fallopian tube to the distal end to wait for fertilization.

The egg must be fully matured to undergo the ovulation process. This is the signal to start the making of leutinizing hormone (LH), which conducts the matured egg from the ovarian follicle all the way to the fallopian tube passage.

The ready egg is ushered to the point of fertilization. It is again the hypothalamus that begins the procedure. The pituitary gland receives the signal and produces the leutinizing hormones in a big dose.

The follicle, which developed the egg, is transformed to a hormone producer once the egg is matured and released. This development process includes many eggs, which mature with the help of the follicle-stimulating hormone (FSH).

The leutinizing hormone conducts the matured eggs from the follicles that then start to produce progesterone. It is the same follicle, which becomes the corpus luteum to make progesterone.

The progesterone also helps in shoring up the uterus by making the lining strong. Progesterone is also further produced during pregnancy by the placenta to support the endometrium.

Detecting ovulation – when  do you ovulate?

Menstrual period timing ( Calendar method)

To determine the length of the menstrual cycle, one only needs to note the date of the beginning of the menstrual period (first day of flow) for two consecutive periods, and then count the day from one date to the next. Keeping track of the length of menstrual cycles will help determine the approximate time of ovulation, because the next period begins approximately two weeks from the date of ovulation.

The rough rule to calculate the approximate date of ovulation is : NMP minus 14 days, where NMP is the ( expected) date of the next menstrual period. This is because the luteal phase for most women is 14 days long.

Keeping track of the menstrual cycle by charting it can indicate other ovulatory disturbances . For example, if a menstrual cycle that is normally 28 days starts to occur every 35 or 40 days, this may mean that ovulation is disturbed, and an evaluation is needed.
