Fostimon (Urofollitropin)
Fostimon (Urofollitropin) Uses, Dosage, Side Effects, Food Interaction and all others data.
FSH binds to the follicle stimulating hormone receptor which is a G-coupled transmembrane receptor. Binding of the FSH to its receptor seems to induce phosphorylation and activation of the PI3K (Phosphatidylinositol-3-kinase) and Akt signaling pathway, which is known to regulate many other metabolic and related survival/maturation functions in cells.
Used for the treatment of female infertility, urofollitropin or follicle stimulating hormone (FSH) stimulates ovarian follicular growth in women who do not have primary ovarian failure. FSH, the active component of urofollitropin is the primary hormone responsible for follicular recruitment and development.

Fostimon (Urofollitropin) is a gonadotropin used for:
- Induction of ovulation in women who have previously received pituitary suppression: intramuscular and subcutaneous administration
- Development of multiple follicles as part of an Assisted Reproductive Technology (ART) cycle in ovulatory women who have previously received pituitary suppression
Fostimon (Urofollitropin) is also used to associated treatment for these conditions: Infertility, Assisted Reproductive Technology therapy, Ovulation induction therapy
