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 information can be gathered from an LH FSH chart?
An LH FSH chart can provide information about the levels of luteinizing hormone (LH) and follicle-stimulating hormone (FSH) in the body. These hormones play a key role in regulating the menstrual cycle and fertility. By analyzing the levels of LH and FSH over time, healthcare providers can assess hormone balance, ovulation, and potential reproductive issues.
How do LH and FSH levels impact the menstrual cycle?
LH and FSH are hormones that play a crucial role in the menstrual cycle. FSH stimulates the growth of follicles in the ovaries, which contain eggs. LH triggers ovulation, the release of the egg from the follicle. The levels of LH and FSH fluctuate throughout the menstrual cycle, with peaks in LH triggering ovulation. Imbalances in these hormone levels can lead to irregularities in the menstrual cycle, such as missed periods or difficulty conceiving.
What role do FSH and LH play in the regulation of the menstrual cycle?
FSH (follicle-stimulating hormone) and LH (luteinizing hormone) are two hormones that play key roles in regulating the menstrual cycle. FSH helps stimulate the growth of follicles in the ovaries, which contain eggs. LH triggers ovulation, the release of a mature egg from the follicle. Together, FSH and LH help control the timing and progression of the menstrual cycle.
What hormone stimulates follicle development by female ovaries and sperm development by male testes is?
Follicle-stimulating hormone (FSH) stimulates follicle development in female ovaries, while luteinizing hormone (LH) stimulates the release of mature eggs. In male testes, FSH stimulates sperm development.
How are the FSH and LH are released by the hypothalamus?
FSH and LH are released by the hypothalamus in response to gonadotropin-releasing hormone (GnRH) stimulation. GnRH is released in pulses into the bloodstream, which then triggers the release of FSH and LH from the pituitary gland. These hormones play a key role in regulating the reproductive system and stimulating the production of sex hormones in both males and females.
What are the male sex hormone?
Testosterone, oestrogen, Fsh, LH,prolactinThere are two primary ones: Testosterone, and androgen.
What does the LH FSH graph reveal about the hormonal levels in the reproductive system?
The LH FSH graph shows the levels of luteinizing hormone (LH) and follicle-stimulating hormone (FSH) in the reproductive system. These hormones play a key role in regulating the menstrual cycle and ovulation. The graph can reveal patterns of hormone fluctuations that indicate the stage of the menstrual cycle and the health of the reproductive system.
What does the fsh lh graph reveal about the hormonal levels in the reproductive system?
The FSH LH graph shows the levels of follicle-stimulating hormone (FSH) and luteinizing hormone (LH) in the reproductive system. These hormones play a key role in regulating the menstrual cycle and ovulation. The graph can reveal patterns of hormone fluctuations that indicate the stage of the menstrual cycle and the functioning of the reproductive system.
