What is Follicle Stimulating Hormone
What is Follicle Stimulating Hormone (FSH), is one of the gonadotrophic hormones, and the other being a Luteinizing Hormone (LH). The pituitary gland releases both into the bloodstream and body, and Follicle Stimulating Hormone (FSH) is one of the hormones essential for the development function of women’s ovaries and men’s testes. In women, Follicle Stimulating Hormone (FSH) stimulates the growth in the ovary before the release of an egg from one follicle to the ovulation. It also increases estradiol production. In men, Stimulating Follicle Hormone (FSH) acts on the Sertoli cells of the testes to stimulate sperm production (spermatogenesis). How is Follicle Stimulating Hormone (FSH) control? The release of Follicle Stimulating Hormone (FSH) is regulated by the levels of some circulating hormones released by the ovaries and testes. This system is called the hypothalamic–pituitary–gonadal axis. The gonadotropin-releasing hormone is published in the hypothalamus and the receptors in the anterior pituitary gland to stimulate both the synthesis release of Follicle Stimulating Hormone (FSH) and Luteinizing Hormone (LH). The released Follicle Stimulating Hormone (FSH) is carried in the bloodstream, where it binds to receptors in the testes and the ovaries. Using this mechanism Follicle Stimulating Hormone (FSH), along with Luteinizing Hormone (LH), can control the functions of the ovaries and testes.
In women, when hormone levels are deficient, and it has complication the menstrual cycle, this is sensed by nerve cells in the hypothalamus. These cells produce the more gonadotrophin-releasing hormone, which in turn stimulates the pituitary gland to produce more Follicle Stimulating Hormone (FSH) and Luteinizing Hormone (LH), and release these into the bloodstream. The rise in Follicle Stimulating Hormone (FSH) and stimulates the growth of the follicle in the ovary, and the cells of the follicles produce increasing amounts of estradiol. In turn, this production of these hormones is sensed by the hypothalamus, and pituitary gland and less gonadotrophin-releasing hormone and Follicle Stimulating Hormone (FSH) will be released, However, as the follicle grows, and more and more estrogen is produced from the follicles, it simulates a surge in luteinizing hormone (LH) and Follicle Stimulating Hormone (FSH), which stimulates the released egg from a mature follicle – ovary.
During women menstrual cycle, there is a rise the Follicle Stimulating Hormone (FSH) secretion in the first half of the period and stimulates follicular growth in the ovary, after ovulation, each month the ruptured follicle forms and Corpus luteum that produces high levels of progesterone. This inhibits the release of stimulating Follicle Stimulating Hormone (FSH), and towards the end of the cycle the Corpus luteum breaks down, and progesterone production decreases. The next menstrual period begins when Follicle Stimulating Hormone (FSH) starts the production again, and get back to normal…
Now In men, the production of Follicle Stimulating Hormone (FSH) is regulated by levels of testosterone and inhibin, both produced by the testes. Follicle Stimulating Hormone (FSH) regulates testosterone levels and when this rise they are sensed by nerve cells in the hypothalamus so that gonadotropin-releasing hormone secretion and consequently Follicle Stimulating Hormone (FSH) is decreased. The opposite occurs when testosterone levels drop. This is known as a ‘Negative Feedback in the body’ control so that the production of testosterone remains steady. But the sensed by cells in the anterior pituitary gland rather than the hypothalamus.
What happens if you have too much Follicle Stimulating Hormone (FSH)?
Most often, and raised levels of Follicle Stimulating Hormone (FSH) are a sign of malfunction in the ovary or testis. If the gonads fail to create enough estrogen, testosterone and inhibit, the right feedback control of Follicle Stimulating Hormone (FSH) production from the pituitary gland is lost, and the levels of both Follicle Stimulating Hormone (FSH) will rise. This condition is called hypogonadotropic-hypogonadism and is associated with primary ovarian failure or testicular failure. This is seen in states such as Klinefelter’s syndrome in men and Turner syndrome in women.
In women, Follicle Stimulating Hormone (FSH) levels also start to rise naturally in women around the menopausal period, reflecting a reduction in the function of the ovaries and decline of estrogen and progesterone production.
There are rare pituitary conditions that can raise the levels of Follicle Stimulating Hormone (FSH) in the bloodstream. This overwhelms the regular negative feedback and can cause ovarian hyperstimulation syndrome in women ovaries.
Symptoms: This includes enlarging of the ovaries and potentially dangerous accumulation of fluid in the abdomen, and triggered the rise in ovarian steroid output. Which leads to pain and other problems in the pelvic area of the body.
What happens if don’t produce enough Follicle Stimulating Hormone (FSH)?
In women, lack of Follicle-Stimulating-Hormone (FSH) leads to incomplete development in puberty o poor ovarian function (ovarian failure), and In this situation ovarian follicles do not grow properly and do not release in the egg, thus leading to infertility. Since levels of Follicle-Stimulating-Hormone (FSH) in the bloodstream are low, this condition is called hypogonadotropic-hypogonadism. This condition is called Kallman’s syndrome, which is associated with a reduced sense of smell.
Sufficient Follicle-Stimulating-Hormone (FSH), this action is also needed for proper sperm production in men, in case of complete absence of Follicle Stimulating in men, and the lack of puberty and infertility due no production of sperm is called (azoospermia). Partial Follicle-Stimulating-Hormone (FSH) deficiency in young men, can also cause delayed puberty and low sperm production, called (oligozoospermia), but fathering a child may still be possible. Follicle-Stimulating-Hormone (FSH) occurs after puberty; there will be a similar loss of fertility…]]>
