Medical Video: Female Reproductive System - Menstrual Cycle, Hormones and Regulation
You may understand a little more about the human reproductive system. Starting from sperm production in men and egg cells in women, until the meeting of these two cells until the occurrence of pregnancy. However, do you know that we can all undergo all of these functions the body is helped by two different types of hormones. Come on, get acquainted with follicle stimulating hormones (FSH) and luteinizing hormone (LH).
Both of these hormones play an important role in the reproductive system of men and women. Already know what are the functions of the hormones FSH and LH and their differences? Relax, all the answers you can find in the following review.
Where does the hormone FSH and LH come from?
All hormones produced in the body come from the hypothalamus. The hypothalamus is a small part of the center of the brain that is directly related to the pituitary gland, the "master gland" which controls many vital functions in the body.
The hypothalamus stimulates the endocrine glands to produce many hormones, one of themgonadotropin-releasing hormone (GnRH). This GnRH hormone is the parent of most hormones in the body, especially male and female reproductive hormones.
During the productive period, GnRH will stimulate the pituitary gland to release the hormones FSH and LH. Basically, these two hormones have tasks that are not much different, often working together to optimize the reproductive system of women and men.
Simply put, FSH is a hormone that is responsible for regulating egg production in women and sperm in men. Meanwhile, the LH hormone works with FSH to regulate the smooth menstrual cycle and maintain testicular function during the reproductive period.
Differences in the function of the hormones FSH and LH
During this time you might think that the hormones FSH and LH are only owned by women. In fact, in fact men also have hormones FSH and LH, you know.
Although both maintain the reproductive system, the function of the hormones FSH and LH in women and men remains different. So as not to be confused, let's peel one by one.
The function of the hormones FSH and LH in women
The main function of FSH and LH hormones in women is to make sure the menstrual cycle runs smoothly every month. Both of these hormones work together to stimulate the growth and maturity of the alias follicle of the egg. Starting from the beginning of the formation, ovulation or release of eggs from the ovary, until the end of the menstrual period.
At the beginning of the menstrual cycle, the hormone FSH levels in the body will increase but the amount of LH hormone decreases. FSH is used to stimulate follicles to produce hormones estrogen and progesterone. The egg will then be ripened to prepare for the fertile period.
During the fertile period, the hormone estrogen will send a signal to the pituitary gland to stop producing FSH and start producing a lot of LH - the opposite of that. This LH hormone will trigger ovulation aka the release of eggs from the ovary.
Egg follicles that have been released will turn into corpus luteum or empty follicles. Furthermore, the corpus luteum will release the hormone progesterone to thicken the uterine wall tissue, just in case a pregnancy occurs. But if there is no pregnancy, then the progesterone level will go back down and cause your uterine wall to decay. This is what we call menstruation.
The function of the hormones FSH and LH in men
The function of the hormones FSH and LH in men is actually not much different from women. Both of these hormones ensure the process of forming healthy sperm cells (spermatogenesis) in men goes well.
Sertoli cells in the testis need the hormone FSH to produce androgen binding protein (ABP). This protein is the key to stimulating the formation of healthy sperm in men. After that, it is the turn of the pituitary gland that will secrete LH hormone. Well, this LH hormone will stimulate Leydig cells to produce testosterone.
As you probably already know, testosterone is a male sex hormone that produces sperm. When the testosterone produced is low, the quantity and quality of sperm will certainly decrease. Whether in terms of number, shape, or less optimal movement. The fatal impact is that men may experience erectile dysfunction because testosterone is far from enough.
