What is the origin of FSH?
FSH is made by your pituitary gland, a small gland located underneath the brain. FSH plays an important role in sexual development and functioning. In women, FSH helps control the menstrual cycle and stimulates the growth of eggs in the ovaries.
How is recombinant FSH made?
Two recombinant follicle-stimulating hormone (FSH) products, follitropin-beta (Follistim in the United States, Puregon in Europe) and follitropin-alpha (Gonal-F), join compounds derived through transfecting nonhuman cell lines with genetic material capable of replicating identical amino acid sequences to human …
What is recombinant human FSH?
Gonal-f is a recombinant form of human FSH (r-hFSH), an endogenous gonadotropin which is being produced in genetically engineered chinese hamster ovary cells and is indicated for induction of ovulation and pregnancy in anovulatory infertile women in whom the cause of infertility is functional and not due to primary …
What is synthetic FSH?
Synthetic ovulation stimulants are drugs that stimulate ovulation or release of ovum from the ovaries. The drug in this category has a similar structure to estrogen. FSH and LH secretion stimulates growth of ovarian follicles and subsequent release of the egg.
Why is FSH inhibited?
The rise in follicle stimulating hormone stimulates the growth of the follicle in the ovary. After ovulation the ruptured follicle forms a corpus luteum that produces high levels of progesterone. This inhibits the release of follicle stimulating hormone.
What is the full meaning of FSH?
Follicle-stimulating hormone (FSH) is a hormone associated with reproduction and the development of eggs in women and sperm in men. This test measures FSH in the blood. FSH is made by the pituitary gland, a small organ located in the center of the head behind the sinus cavity at the base of the brain.
Is FSH recombinant therapeutics?
Human follicle-stimulating hormone (FSH) is now produced in vitro by recombinant DNA technology. FSH being a complex heterodimeric protein, a eukaryotic cell line has been selected for expression work (Chinese hamster ovary cells).
What is normal FSH level for female?
Female: Before puberty – 0 to 4.0 mIU/mL (0 to 4.0 IU/L) During puberty – 0.3 to 10.0 mIU/mL (0.3 to 10.0 IU/L) Women who are still menstruating – 4.7 to 21.5 mIU/mL (4.5 to 21.5 IU/L)
What are the symptoms of high FSH?
What Are The Symptoms Of High FSH?

What causes high FSH levels in females?
High FSH Levels a loss of ovarian function, or ovarian failure. menopause. polycystic ovarian syndrome, which is a condition in which a woman’s hormones are out of balance, causing ovarian cysts. a chromosomal abnormality, such as Turner’s syndrome that occurs when part or all of one of a woman’s X chromosomes is …
Which is inhibits FSH?
Estradiol is a potent inhibitor of FSH release acting directly at the gonadotrope to inhibit mRNA transcription. Thus inhibin together with both estradiol and progesterone secreted by the corpus luteum, accounts for the suppression of FSH and thus follicular development in the luteal phase of the human menstrual cycle.
