IVF process and steps

IVF is an assisted reproductive technology, which helps couples who cannot conceive naturally realize their reproductive aspirations through in vitro fertilization and embryo transfer. The flow and steps of IVF will be described in detail below.

1、 Initial diagnosis and personalized plan formulation

The process of IVF generally includes several stages, such as initial diagnosis, personalized plan formulation, ovulation promotion, egg collection, sperm extraction and fertilization, embryo culture and embryo transfer. At the initial diagnosis stage, couples need to go to the hospital for examination and interview, and the doctor will know their reproductive health status and the birth history of the baby in detail. Doctors will perform a series of physical examinations on the couple, including endometrial thickness, ovarian function, sperm quality, etc. According to the examination results, doctors will develop personalized programs, including ovulation promotion, egg collection, sperm extraction and other steps.

2、 Ovulation promotion, egg collection and sperm extraction

The ovulation promotion stage is to improve the quality and quantity of eggs. According to the personalized plan, doctors will carry out ovulation promotion treatment for female patients, including the use of ovulation promoting drugs to monitor follicle growth. Egg collection is usually performed 36 hours after ovulation. Doctors will puncture the ovary to extract eggs under the guidance of vaginal ultrasound. At the same time, men need to provide fresh semen samples. Sperm extraction can be carried out by natural ejaculation, manual semen sampling or sperm extraction.

3、 Embryo culture and embryo transfer

After the eggs are collected, the eggs and sperm are placed in the incubator for in vitro fertilization. Usually, the egg will combine with the sperm in the incubator and divide to form a fertilized egg. In the process of embryo culture, doctors will select the most active embryo for culture according to the shape and development degree of the fertilized egg. The incubation time is generally 3-5 days. Embryo transfer is generally carried out on the 3rd to 5th days of embryo culture. Doctors transfer embryos into the patient's uterus through vaginal cannula. After transplantation, patients need further observation and nursing.

4、 Pregnancy detection and pregnancy maintenance

Usually 14 days after the embryo transfer, the patient can have a blood pregnancy test. If the result is positive, the patient will continue to receive pregnancy maintenance treatment, including progesterone and other drugs. In the process of pregnancy maintenance, patients need to regularly check the pregnancy, including embryonic development, fetal heart rate monitoring, endometrial thickness and other indicators. The doctor will adjust the drug dose and treatment plan according to the examination results to ensure the normal development of the fetus. With the support of medical technology, IVF technology can help couples who are unable to conceive naturally realize their fertility aspirations. Each step requires the meticulous operation of doctors and the active cooperation of patients, as well as the psychological support and understanding of couples. Every step in the IVF process is crucial. Only comprehensive cooperation and professional treatment can improve the success rate of IVF.
