Progesterone Hormones

Progesterone is a women steroid hormone responsible for the changes in the endometrium in the second half of the menstrual cycle. It is also responsible for fertility and pregnancy. Progesterone hormones prepare the lining of the uterus (endometrium) for implantation of a fertilized egg and its development, and maintain the uterus throughout pregnancy. Low progesterone hormones have negative influences on your body, fertility, pregnancy and can even lead to an expelling of a fertilized egg.

Progesterone Hormones Production:

After ovulation, the "yellow body" (corpus luteum) that released the mature egg into the fallopian tube begins to secrete high levels of progesterone from the granulosa cells within it. This hormone stimulates the growth of rich blood vessels that supply the uterus lining (endometrium).

It also causes the expansion of tiny glands in the endometrium that produce a fluid (uterine fluid) that can be used to nourish sperms and embryos that find their way into the uterus.These tiny glands are created by the estrogen hormone and the progesterone takes over the job of making them mature into "feeding structures".

The production of progesterone will normally drop away after about 10 days beyond ovulation. It is this sudden reduction in the hormone that will prompt the menstruation period to begin due to the reduced oxygen supply from the blood vessels that were previously encouraged to grow by the progesterone hormone.
