Formation process of test tube baby
In vitro fertilization (IVF) is realized through the transfer of fertilized eggs of women in the process of assisted reproduction by IVF technology (often called IVF technology). This technology has been widely used in many infertile couples. It provides opportunities for those couples with reproductive disorders to realize their reproductive dreams. The formation process of IVF can be described in detail from many aspects, including women's internal environment preparation, egg collection, in vitro fertilization and transplantation.
Women's internal environment preparation
The formation process of IVF first requires the preparation of women's internal environment. Before starting treatment, doctors usually carry out a series of examinations to determine women's ovarian function, uterine conditions and hormone levels in the body. If there are any potential problems, such as poor ovarian function or thin endometrium, the doctor may recommend some auxiliary measures, such as adjusting hormone levels, improving ovarian function or increasing the thickness of endometrium.
Once the woman's internal environment is fully prepared, the doctor will arrange the injection of ovarian stimulation drugs according to her menstrual cycle. These drugs aim to stimulate the ovaries to produce more eggs to increase the chance of successful pregnancy. During this period, doctors will monitor the ovarian response and hormone levels through regular ultrasound examinations and blood tests.
When the follicles reach the proper size and number, the doctor will instruct women to inject human chorionic gonadotropin (hCG) to guide the follicles to ovulate. Within about 36 hours after the injection, the woman will have an egg collection operation.
Egg collection
Egg collection is a key step in IVF. The operation will be carried out in a regular hospital or clinic and operated by an experienced doctor. Before surgery, a woman will usually receive general anesthesia or local anesthesia to ensure that she has no pain or discomfort during the collection process.
The doctor will use a slender needle to puncture the woman's ovary and locate the follicle through ultrasound guidance. Then, the doctor will suck out the eggs one by one through a needle. This process usually lasts only a few minutes, but multiple eggs can be collected to increase the probability of successful transplantation.
After collection, the eggs will be transferred to the laboratory for in vitro fertilization.
In vitro fertilization
During in vitro fertilization, doctors will select high-quality sperm and eggs from couples and place them in culture dishes to create an environment similar to natural pregnancy. After a period of time, the doctor will observe the results and determine whether the fertilization is successful.
If successful fertilization, the fertilized egg will be further cultured for several days to support its development. The doctor will determine the best time for transplantation according to the quantity, quality and development of the fertilized eggs.
embryo transfer
Embryo transfer is the last step of IVF. This process is usually carried out in the laboratory. Doctors will use long and thin tubes to transfer multiple embryos into the uterus of women, hoping that at least one can successfully implant.
The process of embryo transfer is usually painless and does not require anesthesia. Doctors will use ultrasound guidance to ensure the correct positioning of the embryo and make the transfer process as smooth as possible. After transplantation, women usually have a rest period to provide the best implantation conditions.
In summary, the formation process of IVF involves many links, including women's internal environment preparation, egg collection, in vitro fertilization and embryo transfer. The success of this technology requires comprehensive consideration of many factors, and requires a highly professional medical team to operate. Through IVF technology, many infertile couples have realized their reproductive dreams.
