Principle and mechanism of IVF ovulation stimulating needle

The IVF ovulation promoting needle helps women to release more mature eggs and increase the chance of pregnancy through drug intervention. Its principle and mechanism mainly involve the following aspects.

1. Promote and regulate follicle growth

The ovulation stimulating needle is mainly composed of gonadotropin, including human chorionic gonadotropin (HMG) and human amniotic gonadotropin (FSH). These hormones can simulate the role of luteinizing hormone in women and promote the growth and development of follicles. During the normal ovulation cycle, the ovary will release one main follicle, and other follicles will stop growing on their own. However, after the use of ovulation stimulating needles, the gonadotropin in the body will stimulate the simultaneous growth of multiple follicles and increase the number of mature eggs.

2. Control ovulation time

The ovulation stimulating needle can also help control the ovulation time and ensure that eggs are collected at the best time. Generally, the use of ovulation promoting needle will be carried out from the 8th to 12th day after the end of basic treatment period to make the follicle develop to an appropriate size. After that, by regularly monitoring blood hormone levels and follicle size, doctors can determine the best time for ovulation, and at this time conduct oviduct retrieval.

3. Increase the chance of pregnancy

The use of ovulation promoting needles can increase the number of mature eggs in the body and improve the chance of pregnancy. This is especially important for women with ovulation problems or poor egg quality. At the same time, by controlling the ovulation time, we can ensure that eggs are collected at the best time and improve the success rate of fertilization.

4. Scope of application and precautions

Test tube baby ovulation promoting needle is suitable for women with ovulation disorders, low ovarian function, polycystic ovary syndrome and other infertility symptoms. However, in some special cases, such as cysts or tumors, it may be necessary to avoid the use of ovulation stimulating needles. In addition, the use of ovulation promoting needle should be carried out under the guidance of doctors, and the dose and timing should be strictly controlled to avoid side effects. In conclusion, IVF ovulation promoting needle can help women achieve pregnancy and fertility by promoting follicle growth, controlling ovulation time and increasing pregnancy opportunities. It is a safe and effective assisted reproductive technology, which can bring good news to infertile patients under appropriate circumstances. However, doctors' judgment and guidance are required before use to ensure safety and success.
