Principles of IVF

In vitro fertilization (IVF) is a method to help infertile patients achieve fertility through in vitro fertilization (IVF). Its principle mainly includes the following aspects:

1. Ovulation induction

First of all, doctors will give ovulation induction treatment to women. By using gonadotropin drugs to stimulate ovarian development and ovulation, to increase the chance of pregnancy. This process usually requires close monitoring to ensure the accuracy of follicle development and ovulation time.

2. Collect eggs and sperm

When the female ovulation period is approaching, doctors will use ultrasound guided transvaginal puncture technology to collect follicles in the ovary. At the same time, sperm can be collected from men through manual ejaculation, semen puncture or testicular sperm collection.

3. In vitro fertilization

After collecting eggs and sperm, the doctor will place them in a culture dish for in vitro fertilization. This process involves placing eggs and sperm in a specific culture medium to provide a suitable environment for fertilization.

4. Embryo transfer

After in vitro fertilization, doctors will cultivate the fertilized eggs into embryos, and then select the healthiest embryos for transplantation. The embryo can be transferred directly into the uterine cavity or assisted by an auxiliary device.

In general, the principle of IVF is mainly through ovulation induction, egg and sperm collection, in vitro fertilization, embryo transfer and other steps.

Is the success rate of IVF guaranteed

The success rate of IVF is affected by many factors, including patient's age, infertility causes, medical technology level, etc. Generally speaking, to ensure the success rate of IVF, the following aspects should be guaranteed:

1. Professional level of the hospital

It is very important to select a hospital with rich experience and professional technology for IVF operation. A high-level hospital usually has a professional team, equipped with advanced equipment and technology, and can provide all-round diagnosis and treatment services, thus improving the success rate of IVF.

2. Individual differences of patients

Age is one of the important factors that affect the success rate of IVF. The ovarian function of young women is generally good. The more ovarian reserves of patients, the higher the success rate of IVF. In addition, the cause of infertility will also affect the success rate, such as endometriosis, tubal obstruction and other factors will reduce the success rate.

3. Personalized treatment plan

Making personalized treatment plan is an important means to improve the success rate of IVF. Doctors will tailor appropriate treatment plans according to the specific conditions of patients and the differences between different systems, so as to improve the success rate.

In general, the success rate of IVF needs to be guaranteed by the professional level of the hospital, individual differences of patients and personalized treatment programs.

Summary

Based on in vitro fertilization technology, IVF helps infertile patients achieve fertility by promoting ovulation, collecting eggs and sperm, in vitro fertilization and embryo transfer. The guarantee of high success rate requires the hospital to have professional level and develop personalized treatment plan according to individual differences of patients. However, there is still some uncertainty about the success rate of IVF. Patients need to fully understand their own conditions and choose the appropriate hospital for treatment.
