Specific steps of IVF

IVF refers to the method that the embryos conceived in the process of IVF are transferred into the mother's uterus to realize pregnancy and delivery. Test tube baby technology has developed for many years, and now it has become an effective means to solve the problem of infertility. The specific steps of IVF will be described in detail from four aspects.

Women's ovulation guide

The first step of IVF is female ovulation. Usually, at the beginning of a woman's menstrual cycle, doctors will stimulate ovarian development through drugs to obtain more follicles and eggs. These drugs can be taken orally or injected. The doctor will determine the type and dosage of drugs to be used according to the specific situation and needs of each patient.

During the period of receiving ovulation guidance, women need to carry out regular ultrasonic examination and blood testing to monitor the development of follicles and hormone levels. When the follicle size and hormone level reach the appropriate level, the doctor will tell the woman to collect eggs.

Egg collection and sperm extraction

Before the egg matures, doctors will use ultrasound guided puncture technology to extract the egg from the follicle. This process usually needs to be carried out under general anesthesia and completed in the operating room. Doctors will use a slender needle to extract eggs and store them in a petri dish.

At the same time, sperm also needs to be extracted. Sperm can be extracted either by natural ejaculation or by manual means from the testis or epididymis. The extracted semen will undergo special treatment and purification to obtain high-quality sperm.

In vitro fertilization and embryo culture

After egg collection and sperm extraction, in vitro fertilization will be carried out. This is the process of combining eggs and sperm to fertilize eggs. Usually, doctors will put eggs and sperm in a culture dish and provide appropriate temperature and environmental conditions in the incubator to promote the fertilization process.

After successful fertilization, the embryo will continue to be further cultured in the incubator. Doctors will determine the best time for embryo transfer according to the development of the embryo.

Embryo transfer and pregnancy monitoring

Embryo transfer is the last step in IVF technology. It transfers the cultured embryos into a woman's uterus. This process is usually painless and does not require hospitalization. The doctor will use a slender tube to carefully place the embryo into the uterus and ensure that the embryo is in the proper position. After that, women need a period of rest and recovery.

Next, women need to carry out pregnancy monitoring, including regular ultrasound and blood testing, to ensure the successful implantation of embryos and normal development. If pregnancy occurs, the doctor will continue to monitor the pregnancy period of women and provide corresponding support and care.

Summary

The specific steps of IVF include women's ovulation guidance, egg collection and sperm extraction, in vitro fertilization and embryo culture, embryo transfer and pregnancy monitoring. Each step requires strict operation and professional medical team. IVF technology provides a hope for those couples who cannot conceive naturally to realize their dreams.
