The hormone that stimulates a follicle to grow and mature each month is follicle-stimulating hormone (FSH). Produced by the pituitary gland, FSH plays a crucial role in the ovarian cycle by promoting the development of ovarian follicles. As the follicles mature, they also produce estrogen, which further regulates the menstrual cycle.

What gland produces the egg cells and and hormones?
The hypothalamus in the brain releases Gonadotropin-Releasing Hormone to the pituitary gland, located in your brain behind the eyes. The pituitary gland releases Follicle-Stimulating Hormone (FSH) and Luteinizing Hormone (LH), which go to the ovaries. FSH stimulates the selection of an egg from the ovary, and a surge of LH release stimulates the release of the egg for fertilzation. In the ovary, Theca cells release Testosterone which travels to nearby Granulosa cells which convert the testosterone to estrogen. Theca cells also make progesterone, which is necessary for growing the endometrium, which is what bleeds during the menstrual cycle.
What ruptures on the ovarian cortex each month?
Follicles containing eggs rupture on the ovarian cortex each month during ovulation. When a follicle ruptures, it releases the mature egg into the fallopian tube for potential fertilization.
Why is FSH no longer needed after ovulation?
FSH is Follicle Stimulating Hormone. You do not need it in the same month after ovulation has already occurred, but you need it each month before ovulation.
The maturation of an egg cell during the ovarian cycle takes place in the?
The maturation of an egg cell during the ovarian cycle takes place in the follicles within the ovaries. Each month, a follicle containing an egg cell develops and matures in response to hormone signals. When the egg is fully mature, it is released during ovulation.
What is the function of the LTH hormone?
At puberty, the hypothalamus produces GnRH (gonadotropin releasing hormone.) GnRH then stimulates production of LH (leutinizing hormone) and FSH (follicle stimulating hormone)which are released by the pituitary gland. In males, LH causes secretion of testosterone and other androgens by the interstitial cells (located in between the seminiferous tubules in the testies.) Testosterone,among others duties, aids FSH in the stimulation of spermatogenesis (production of spermatozoa) and promotes the functional maturation of spermatozoa.
What is role of fsh and lh in male?
Inside of a woman's ovaries there are thousands of follicles containing immature eggs. Every month one of these follicles matures and releases the egg cell. The female cycle is regulated by female reproductive hormones under the control of the pituitary gland, a small gland located at the base of the brain. The job of the pituitary gland, as far as reproduction is concerned, is to release two important hormones: The Follicle Stimulating Hormone (FSH) The Luteinizing Hormone (LH) FSH controls the first half of the menstrual cycle by stimulating the maturation of the ovarian follicles. Many follicles mature during each cycle, but the one that reaches maturity first will release the egg. FSH stimulate the follicle cells to produce the hormone estrogen, which stimulates the preparation of the endometrium, needed for implantation in case the egg is fertilized. High levels of estrogen trigger the LH surge causing the release of the egg from the mature follicle. This process is called ovulation. LH stimulates the progesterone production from the corpus luteum, which supports the second half of the menstrual cycle. During this phase estrogen levels decrease while progesterone levels increase. If the eggs becomes fertilized and the embryo successfully implants itself into the lining of the uterus, progesterone production continues during the entire course of the pregnancy. If the egg is not fertilized, estrogen and progesterone levels decrease, triggering the shading of the uterus through the process of menstruation. the menstrual period and a new cycle will begin.
What are sign of Ovarian follicle atresia?
An ovarian follicle atresia is a process in which immature ovarian follicles physically decline. Roughly 20 ovarian follicles mature every month but only one of them is ovulated and the rest go through the process of atresia. As such, there is no specific sign of ovarian follicle atresia as it is a natural process in the female reproductive cycle.
What is Stores mature sperm?
A pair of Ovaries. In pelvic cavity,there are two ovaries placed, besides uterus.In intrauterine life there are millions of ova in the ovaries.At birth, the number is about 1 million in each ovary.At puberty the number is about 100,000 in each ovary. Out of witch only about 300 to 400 will be liberated. After menarche, there may be few unovulatotry cycles but then each month you have one ovum liberated from either of the ovaries on fourteenth day of menses, if the cycle is of 28 days. (It's actually a day fourteen days before expected menses.) Each month Grafian follicle matures, under the influence of Follicle stimulating hormone from Pituitary gland and on the day of ovulation, there is surge of Leutenizing hormone and follicle ruptures, liberating the ovum in peritoneal cavity, witch is taken up by Fimbriated end of Fallopian tube. If get fertilized, it will start dividing by Mitosis and usually on eighth day after fertilization, it will be embedded in the body of uterus and pregnancy continues.After rupture of follicle, a white body called as Corpus lute-um secretes the hormone called Progesterone, witch bring about secretory changes in in inner wall of uterus, making it ready for pregnancy. (Earlier Grafian follicle secrete the hormone Estrogen.)if not fertilized,menses will be there.
How does the birth control pill work?
Birth control pills work by giving your body additional estrogen and progesterone, at different amounts during the month. This increase in estrogen and progesterone works via a negative feedback loop; in other words, it tells your body that there is a lot of estrogen and progesterone and therefore it needs to shut off the pathways that produce that estrogen and progesterone. To do this, the body lowers the amount of another hormone, FSH. This hormone, also known as follicle-stimulating hormone, not only affects the release of estrogen and progesterone, but also is necessary for follicle development. Birth control pills decrease the amount of FSH, making it impossible for your follicles to develop. Consequently, these follicles can never mature and release the egg.
What are small cavities in the ovary?
Small cavities in the ovary are known as ovarian follicles. These structures contain developing eggs and are essential for ovulation and fertility. Each month, one follicle will mature and release an egg during the menstrual cycle.
Does caffeen cause overian cysts?
no.. The normal function of the ovaries is to produce an egg each month. During the process of ovulation, a cyst-like structure called a follicle is formed inside the ovary. The mature follicle ruptures when an egg is released during ovulation. A corpus luteum forms from the empty follicle, and if pregnancy does not occur, the corpus luteum dissolves. Sometimes, however, this process does not conclude appropriately, causing the most common type of ovarian cyst -- functional ovarian cysts.
What is the accuracy of a six month hair follicle test compared to a three month hair follicle test?
Not very accurate. The testing industry generally accepts that tests are accurate for a 3 month period. After that the hair is considered too old and the results are less than accurate to PROVE that you have taken drugs.
