What drugs should be used for IVF lowering?

Descending IVF refers to reducing female ovarian function, promoting the increase of ovarian ovulation and the development of ovarian ovulation follicles, and improving the success rate of IVF through drug regulation and auxiliary technology. In the treatment of IVF, the commonly used regulatory drugs include follicle stimulating hormone (FSH), luteinizing hormone (LH), methoxybenzylamine (GnRH-a) and luteinizing hormone (hCG).

Follicle stimulating hormone (FSH) and luteinizing hormone (LH)

FSH is a hormone that can promote follicular development and maturation. In IVF treatment, FSH is often used to stimulate the ovary to produce more eggs. Depending on the patient's condition, basic FSH or compound FSH can be used, such as Puregon and Gonal-F. These drugs are generally administered by subcutaneous injection.

LH is a hormone that promotes the synthesis of estrogen by follicular granulosa cells and helps follicle rupture and luteinization after ovulation. In some cases, LH supplementation can improve follicular development and success rate. Some commonly used LH preparations, including Luveris and Menopur, are also administered by subcutaneous injection.

The dosage and scheme of FSH and LH are usually determined by doctors according to the patients' physical conditions and treatment needs.

Methoxybenzylamine (GnRH-a)

Methoxybenzylamine is a drug that inhibits ovulation by inhibiting the secretion of hypothalamus pituitary ovary axis hormones. The use of trimethoprim in the treatment of test tube infants has two main purposes. First, it can inhibit early natural ovulation to avoid the impact of natural ovulation in the IVF cycle. Secondly, it can cause the ovary to stop functioning normally, so that doctors can better control the time of ovulation and egg retrieval.

Methoxybenzylamine is usually administered in the form of nasal spray, which needs to be started at a specific time point.

Luteinizing hormone (hCG)

In IVF treatment, luteinizing hormone (hCG) is often used to induce ovulation. HCG simulates the role of luteinizing hormone, which causes follicle rupture and releases eggs. The use of luteinizing hormone can ensure that the eggs are taken out at the best time to ensure the success of IVF.

HCG is usually administered by subcutaneous injection, and the dose and time point are determined by the doctor according to the specific situation of the patient.

Summary

In order to improve the success rate of IVF, under the guidance of doctors, commonly used drugs include follicle stimulating hormone (FSH), luteinizing hormone (LH), methoxybenzylamine (GnRH-a) and luteinizing hormone (hCG). The use of these drugs can regulate female ovarian function, increase the production and maturation of eggs, and ensure a successful IVF treatment process.

It should be emphasized that the use of these drugs requires the correct guidance and monitoring of doctors, and the dosage and use time need to be adjusted according to the specific conditions of each patient. Only under the guidance of professional hospitals can IVF treatment be safe and effective.
