What is IVF
IVF refers to the process of using assisted reproductive technology to culture and develop fertilized eggs in vitro, and then transfer healthy embryos to the mother's uterus to achieve pregnancy and delivery. Since the birth of the first test tube baby in 1978, this technology has gradually become a blessing for infertile couples, helping countless couples realize their reproductive dreams.
In the field of modern medicine, IVF technology is widely used in infertility caused by many factors. Whether it is female follicular development disorder, abnormal fallopian tube, premature ovarian failure, or male sperm quality is low, the number of sperm is insufficient and other problems, can be solved through the test tube baby technology.
In the process of IVF, it mainly includes the following key steps: selecting the time suitable for embryo implantation in the endometrium to conduct an artificial control cycle, promoting ovulation, collecting eggs, fertilizing eggs and sperm in vitro in the laboratory, cultivating embryos, and finally transplanting healthy embryos into the mother's uterus.
Specific process of IVF
In real life, the process of IVF usually includes the following stages.
The first stage: ovulation induction therapy for women. Through the use of hormone drugs to help women's ovarian development, control the growth of follicles and ovulation time. Doctors will use ultrasound to monitor the growth of follicles to ensure the best time to retrieve eggs.
The second stage: egg collection process. The doctor will guide the needle through the vaginal wall of the woman, and through ultrasound guidance, the follicle needle will be inserted into the uterus. The eggs and egg fluid are extracted and sent to the laboratory for further treatment.
The third stage: in vitro fertilization and embryo culture. Eggs and sperm are fertilized in vitro in the laboratory to form fertilized eggs. The fertilized egg will continue to be cultured to the embryonic development stage. During the culture process, the doctor will monitor the development of the embryo and select the embryo most likely to be implanted successfully.
The fourth stage: embryo transfer. The doctor will put one or more embryos with the most potential development into the female uterus through a catheter. Embryo transfer is usually completed within half an hour without anesthesia. Then, we need to rest for a period of time, so that the embryo has the opportunity to implant, and pregnancy is possible.
Precautions for IVF
The following points should be noted during IVF:
First, choose a formal professional medical institution for IVF. Such institutions must meet comprehensive equipment and technical conditions, and have rich relevant experience and a team of doctors in the area.
Secondly, the use of drugs in IVF should follow the guidance of doctors, closely monitor the physical condition and conduct regular physical examination to prevent complications.
In addition, couples should maintain a positive attitude during IVF, avoid overwork and emotional fluctuations, and create a good living environment.
Success rate and risk of IVF
The success rate of IVF technology will be affected by many factors, including age, physical condition, types of reproductive system diseases, etc. Generally speaking, young couples have a high success rate. According to statistics, the success rate of IVF is usually between 30% and 50%.
However, IVF also has some risks. Hyperstimulation therapy may lead to ovarian hyperstimulation syndrome, which has certain pressure on women's health. In addition, the risk of multiple pregnancy is also high, which may lead to premature delivery, low birth weight and other complications.
In general, IVF technology has brought new hope and opportunities to many infertile couples. Under the guidance of doctors and in accordance with the normal process, IVF can become an effective way to realize the dream of fertility.
