Quality Indicators:
Biological Activity: The biological activity of FSH in urofolitropin is a crucial quality parameter, usually expressed in international units (IU). High - quality urofolitropin has a consistent and high level of biological activity to ensure effective stimulation of follicular development or spermatogenesis.
Purity: Purity is strictly controlled. Impurities, such as other pituitary hormones or contaminants from the urine source, should be minimized. A high - grade urofolitropin product typically has a high purity level to reduce the risk of side effects and ensure the reliability of its therapeutic effect.
Sterility and Endotoxin Level: Since it is an injectable product, strict requirements are placed on sterility. The endotoxin level must be extremely low to prevent pyrogenic reactions in patients.
Applications:
Assisted Reproductive Technologies: The most common application of urofolitropin is in ART. It is used in ovarian stimulation protocols for women undergoing IVF, intracytoplasmic sperm injection (ICSI), or other fertility treatments. By stimulating the growth of multiple follicles, it increases the number of eggs available for retrieval and subsequent fertilization, significantly improving the success rate of these procedures.
Ovulation Induction: In cases of anovulation (lack of ovulation) due to various reasons such as polycystic ovary syndrome (PCOS) or other hormonal imbalances, urofolitropin can be used to induce ovulation. It helps to regulate the ovarian cycle and promote the development of a mature follicle that can release an egg for potential fertilization.
