The cycle and process of IVF
IVF technology is one of the assisted reproductive technologies, which is applicable to couples who cannot conceive naturally. Next, we will introduce the cycle and process of IVF in detail.
1. Preparation for IVF cycle
The preparation for the IVF cycle is to ensure the development of follicles in the female body and the preparation for ovulation.
First, the woman needs to undergo a series of physical examinations, including endocrine examination, gynecological examination, and tubal patency examination. Doctors will develop personalized treatment plans based on the examination results.
Then, women need ovulation induction therapy. Doctors will promote the growth and development of follicles through drugs according to the development of follicles in the woman's body. This process requires multiple ultrasound examinations to determine the follicular development.
Finally, women need to inject ovulation promoting drugs to promote the final maturation of follicles and determine the best time for ovulation. Usually, 36 hours after the follicle matures, the doctor will perform an egg retrieval operation.
2. Egg taking and sperm treatment of test tube babies
Egg retrieval is an important step in the IVF cycle, and is also one of the most critical steps. Usually, 36 hours after the follicle matures, the woman performs an egg retrieval operation.
Egg retrieval is the process of obtaining mature eggs by puncturing the ovary or vagina. Doctors use ultrasound guided fine needles to extract mature eggs. This process is usually performed under intravenous general anesthesia, and the operation time is about 30 minutes.
At the same time, men need to provide fresh semen samples. After the semen sample is processed, high-quality sperm can be obtained.
3. IVF of IVF
In vitro fertilization (IVF) refers to the process of combining the extracted eggs and sperm in the laboratory.
The mature eggs and sperm taken out are placed in the culture dish. Through the culture medium in the culture dish, a suitable environment is provided to promote the combination of sperm and eggs.
Normally, fertilized eggs will appear after 2-3 days. The doctor will select the appropriate embryo transfer time according to the fertilization situation.
4. Embryo transfer of test tube baby
Embryo transfer is the last step in the IVF cycle. It is very important to choose an appropriate time for embryo transfer. Doctors usually choose to transfer embryos after the fertilized eggs develop to 2-5 days.
Embryo transfer is the process of placing an embryo into a woman's uterus so that it can be embedded in the endometrium and further developed. This process is usually carried out directly through the vagina without anesthesia.
After embryo transfer, women need to rest for a period of time to increase the probability of pregnancy. If the pregnancy is successful, the woman needs to check the pregnant woman regularly to ensure the normal development of the embryo.
Summary
IVF cycles and processes include preparation, egg retrieval and sperm processing, in vitro fertilization, and embryo transfer. Through multiple physical examinations and treatments, the preparation for female follicular development and ovulation is ensured. After the egg retrieval operation, the egg and sperm are combined in the laboratory, and the fertilized egg is obtained through in vitro fertilization technology. Finally, the embryo is transferred into the uterus of a woman to complete the process of IVF.
IVF technology provides an opportunity for couples who cannot conceive naturally to obtain offspring. However, IVF technology still has certain risks and uncertainties, which require couples to make careful choices under the guidance of doctors.
