What are the different types of reproductive hormones?

There are several reproductive hormones in the human body, including testosterone, estrogen and progesterone. Human chorionic gonadotrophine (HCG), follicles stimulating hormone (FSH), hormone releasing gonadotrophin (GNRH) and luteinizing hormone (LH) are also essential for the reproductive cycle. Testosterone is often considered a male hormone, but is also in women. Similarly, estrogen is perceived as a female hormone, but is also necessary for men. Some of the other reproductive hormones stimulate estrogen release, testosterone and progesterone, while HCG is necessary during pregnancy.

Although testosterone is necessary for women, many people think about it as a male hormone. In women, this hormone is responsible for tasks such as maintaining muscle mass. In men, he is responsible for the production of sperm and many male characteristics. For example, the growth of testosterone in puberty causes men to grow a face and hair. Testosterone release is Contolled FSH, hormone that helps in productionsperm. The release of FSH is again controlled by GNRH. Increasing testosterone levels stop GNRH production, prevent FSH from release and thus testosterone. This helps to prevent too high the testosterone level.

normally considered female reproductive hormone, estrogen stimulates sexual properties such as breasts, uterus and vaginal development. However, it is also necessary to maintain the male reproductive system and healthy sperm development. In women, estrogen levels in puberty cause breast development and prepare vagina and uterus for pregnancy. In response to the development of the follicle estrogen, it stimulates the uterine lining called the endometrium to start thickening. The follicle is a structure inside the ovaries where eggs grow.

as testosterone, estrogenje stimulated FSH, which in turn is stimulated gnr. The increasing estrogen levels inhibit GNRH production, preventing too high estrogen levels. Low hungerIny estrogen also allow the endometrium to get rid of if the woman does not affect. This release is called menstruation.

Gnrh stimulates the production of luteinizing hormone (LH), another of the reproductive hormones. In men, LH helps in the production and release of testosterone. In women, the hormone transforms follicle into corpus luteum after the egg - or oocyte - was released. Once transformed, Corpus Luteum can start to exclude progesterone in accordance with LH stimulation.

Progesterone is a female reproductive hormone that prevents the uterus from closing and release of the endometrium too early. It also prevents the new follicle from developing as soon as Ooycte is released. Like estrogen, growing progesterone levels reduces Gnrh, which reduces LH, prevents too high progesterone stripe.

The presence of reproductive hormones such as progesterone is necessary for successful pregnancy. Because the rise of many of these hormones prevents their further release,Another hormone must be introduced to continue the pregnancy. Human chorionic gonadotrophin (HCG) is a hormone that is released by trophoblast, cells that eventually become a placenta and umbilical cord, after the embryo implants into endometrium. Unlike many other reproductive hormones, HCG production is not affected by release or inhibition of GNRH. HCG takes over the role of FSH and LH, which allows estrogen and progesterone to be released even after Gnrh is no longer released.
