Conventional IVF
In vitro fertilization (IVF) is the most common method in assisted reproductive technology. It refers to a technology that artificially combines and cultivates mature female eggs and male sperm in vitro, and then transfers embryos into female uterus to help infertile couples achieve fertility. The following is a detailed introduction to conventional IVF from four aspects.
indication
Conventional test tube babies are suitable for a variety of infertility causes, including female anovulation, ovarian dysfunction, fallopian tube blockage, male semen abnormalities, etc. In addition, conventional IVF is also used for genetic screening and selection of some genetic diseases. Some elderly couples who have failed in artificial insemination or in vitro fertilization can also choose conventional IVF to improve the fertility success rate.
The preparatory work for routine IVF includes comprehensive evaluation of couples, determination of the cause of infertility, follicular monitoring and ovulation induction treatment for women, and semen examination and sperm treatment for men. Some hospitals, such as Peking Union Medical College Hospital and Fudan University Affiliated Obstetrics and Gynecology Hospital, have accumulated rich experience in this field and provided professional consultation and personalized treatment programs.
Operation process
Conventional IVF mainly includes superovulation, oocyte retrieval, fertilization and embryo transfer. First, women stimulate multiple ovarian follicles by injecting ovulatory stimulating hormone, and then conduct ultrasonic monitoring to determine the maturity of eggs. Then, under the guidance of the specialist, the eggs were punctured from the ovary.
Then, under aseptic conditions, the sperm and egg are placed in the culture dish, and the sperm is injected into the egg with the help of fine operation under the microscope. The fertilized eggs will continue to be cultivated in the incubator to form embryos. Usually, after 3-5 days of culture, the best quality embryos are selected for transplantation. Embryo transfer is carried out in the uterine cavity, generally without anesthesia, and the operation time is short.
Success rate and precautions
The success rate of conventional IVF is related to many factors. The age of women is one of the most important factors affecting the success rate. The success rate of young women is higher than that of older women. In addition, the success rate will also be affected by the couple's health status, infertility causes, treatment methods, etc. According to statistics, the success rate of conventional IVF is generally about 30%.
During routine IVF treatment, it is necessary to maintain a good attitude, reduce mental stress, reasonably arrange life and work, and avoid strenuous exercise. In addition, we should closely cooperate with the doctor's treatment plan and medication, and regularly review and consult. If the treatment is ineffective for a long time, communicate with the doctor in time to further evaluate and adjust the treatment plan.
Summary
Conventional IVF is an important assisted reproductive technology to help infertile couples achieve fertility. It is applicable to a variety of infertility causes and provides a reliable reproductive choice. Routine IVF procedures include superovulation, oocyte retrieval, fertilization and embryo transfer, which should be carried out under the guidance of doctors. For couples, it is very important to maintain a good attitude and close cooperation with doctors. Through scientific treatment and reasonable lifestyle, conventional IVF can bring healthy babies to infertile couples.
