Operation process of putting test tube baby into uterus

IVF technology is an assisted reproductive technology realized by in vitro fertilization (IVF) or embryo transfer, which provides fertility opportunities for couples who are unable to conceive naturally due to various reasons. The success rate of IVF depends to a large extent on the professional level of hospitals and doctors who implement this technology. The following will elaborate on the operation process of IVF in uterus from four aspects: egg collection, sperm collection, in vitro fertilization and embryo transfer.

Egg collection

Egg collection is the first step in IVF technology. In more advanced clinics and hospitals, ultrasound guided puncture technology is usually used for egg collection. This process is usually carried out in the operating room or under sterile conditions. Doctors will use ultrasound to guide a slender needle through a woman's vagina, uterus and ovary, and extract mature eggs. During this process, women may receive local anesthesia or mild sedation to reduce discomfort. This process requires certain skills and experience, because the number and quality of eggs that can be collected is critical to subsequent in vitro fertilization and embryonic development.

Sperm collection

Before egg collection, men need to provide fresh semen samples. This can be done by masturbation in the sample room provided by the hospital, or by other methods such as sperm extraction or sperm freezing and retention. Usually, semen samples will be processed in the laboratory and selected through special techniques to ensure that the best quality sperm is selected for in vitro fertilization.

In vitro fertilization

In vitro fertilization refers to the combination of sperm and egg in the laboratory. First, eggs and sperm will be carefully checked to ensure that their quality meets the requirements. Subsequently, one or more mature eggs will be placed together with sperm in a culture dish containing nutrients to promote fertilization and normal development of embryos. In vitro fertilization usually adopts two methods: standard in vitro fertilization and single sperm injection (ICSI). The standard in vitro fertilization is to put eggs and sperm in the same culture dish and let them naturally fertilize. ICSI is to inject a single sperm into the egg with a fine needle for fertilization, which is applicable to the situation where the number of sperm is small, the vitality is low or there are other problems.

embryo transfer

After culture and development, select the best embryo for transplantation. Embryo transfer is usually a simple non-invasive process, usually performed in the laboratory. Doctors will use special tubes to place the embryo slowly in the woman's uterus. After the embryo transfer process, women usually need to take a break to improve the probability of successful transfer. Later, doctors may suggest some adjuvant treatment methods, such as progesterone or other hormones, to help fix the embryo and promote implantation. After completing the above operation process, both the husband and wife need to wait several weeks for a pregnancy test to confirm whether the pregnancy is successful.

summary

The operation process of putting IVF into the uterus mainly includes egg collection, sperm collection, in vitro fertilization and embryo transfer. Each step needs professional hospitals and doctors to operate. Through scientific and advanced technology, under the guidance of doctors, patients can obtain higher fertility opportunities. However, IVF technology still needs more research and development to further improve the success rate and safety.
