How does IVF hormone improve pregnancy rate?
Test tube baby (IVF) is an assisted reproductive technology, which is suitable for couples with fertility problems. The use of hormones plays a crucial role in IVF procedures. Hormone therapy can help promote ovulation of the ovary, adjust the thickness of the endometrium, and increase the chance of pregnancy. This article will elaborate on how IVF hormone can improve the pregnancy rate from four aspects: the promotion of ovarian function by hormone therapy, endometrial preparation, support for fertilization process, and preparation for embryo transfer.
1. Hormone therapy promotes ovarian function
In the IVF program, hormone therapy is first needed to promote ovarian function. This usually includes the use of ovulatory hormones (such as gonadotropin and antiestrogen) to stimulate ovarian development and ovulation.
Hormone therapy can promote the development and maturation of follicles and increase the quantity and quality of eggs. In addition, by controlling the amount and time of hormone use, we can avoid excessive development or early rupture of follicles and improve the chance of successful pregnancy.
Hormone therapy can also help adjust ovarian function, balance hormone levels in the body, and solve the problem of insufficient or unbalanced hormone secretion. This provides a good environment for the development of eggs and improves the possibility of pregnancy.
2. Effect of hormone therapy on endometrial preparation
The preparation of endometrium is another important link in the process of IVF. In hormone therapy, the use of oral estrogen and progesterone can help adjust the thickness and quality of endometrium.
The use of hormone can increase the blood supply and thickness of endometrium and provide a more suitable environment for embryo implantation. This is very important for the implantation of fertilized eggs and the breeding of healthy embryos.
In addition, the use of hormone can also help regulate the secretion of endometrium, improve the quality and quantity of cervical mucus, and provide good conditions for sperm survival and movement.
3. Hormone therapy supports the fertilization process
In IVF procedure, fertilization is a key step. Hormone therapy can improve the quantity and quality of fertilized eggs by adjusting hormone levels and follicle size.
The use of gonadotropin can increase the number of follicles and the rate of obtaining fertilized eggs. The use of progesterone can help maintain the luteal function and improve the level of progesterone, and promote the development and protection of fertilized eggs.
At the same time, hormone therapy can also help adjust the intrauterine environment, improve the survival rate of sperm in the uterus and the implantation ability of fertilized eggs. This provides favorable conditions for the fertilization process and increases the chances of IVF success.
4. Preparation of hormone therapy for embryo transfer
Embryo transfer is the last step in the IVF program. Hormone therapy plays an important role before and after embryo transfer.
Before embryo transfer, the use of hormone can help adjust the status of endometrium and provide an environment suitable for embryo implantation. This can increase the implantation rate and survival rate of embryos.
After embryo transfer, hormone use can continue to help maintain luteal function and promote the growth and protection of embryos. This can increase the implantation rate and pregnancy rate of embryos.
In a word, IVF hormone therapy improves the pregnancy rate by promoting ovarian function, adjusting endometrium, supporting fertilization process and preparing for embryo transfer. It provides an effective assisted reproductive technology for couples who have fertility problems, and helps them achieve their dream of fertility.
