Operation process of the third generation IVF in Shanghai
With the continuous development of medical technology, more and more couples choose IVF technology to realize their reproductive dreams. IVF is the process of pregnancy and delivery through in vitro fertilization of female eggs and male sperm, and then transfer the fertilized eggs to the female uterus. The third-generation IVF technology has been upgraded and improved on the basis of traditional IVF, so that more couples who cannot conceive can successfully welcome their babies.
1. Pretreatment
The first step of IVF operation is a series of pretreatment for women. First of all, women need prenatal examination, including gynecological examination, blood examination, etc. Then, doctors will develop personalized conditioning programs according to women's personal conditions, such as reasonable diet, moderate exercise, etc., to improve egg quality and uterine environment. Finally, women need to take medication on time according to the doctor's guidance to promote ovulation and endometrial growth.
In many formal hospitals in Shanghai, such as Shanghai Changhai Hospital and Ruijin Hospital affiliated to Shanghai Jiaotong University School of Medicine, there are professional IVF departments to provide comprehensive medical services and support in the pretreatment stage.
2. Egg taking and sperm separation
Fetching eggs is one of the key steps of IVF, which usually needs to be carried out within 36 hours after women's natural ovulation. First of all, the doctor will, under the guidance of B-ultrasound, pass the thin tube through the vagina into the ovary and extract the mature follicle. The eggs are then fertilized in vitro with sperm from men.
Sperm separation is carried out at the same time as egg retrieval. Doctors will put semen in a centrifuge and separate high-quality sperm according to sperm concentration, vitality and other indicators to ensure the quality and success rate of fertilization.
3. Fertilized embryo culture
After successful fertilization, the doctor will culture the fertilized egg in a culture dish in vitro to provide appropriate nutrition and environmental conditions to promote the development of the embryo. Usually, the embryo will hatch in the culture center for 3-5 days until it develops into an active blastocyst.
The process of embryo culture requires strict control of temperature, humidity and other factors to maintain a good culture environment. During this period, doctors will select the best blastocyst for transplantation according to the quality and development of the embryo.
4. Embryo transfer and blastocyst freezing
When the embryo develops to the appropriate stage, the doctor will select the best blastocyst for transplantation. Transplantation is usually carried out at a specific time in a woman's natural menstrual cycle, that is, when the endometrium is in its best condition. The doctor will send the blastocyst into the uterus through a guide wire or a thin tube to complete the transplant operation.
After embryo transfer, the remaining blastocysts can be frozen for future use. These frozen embryos have a high survival rate and can be unfrozen when needed, improving the chances of success of IVF.
Summary
The operation process of the third generation IVF in Shanghai mainly includes pretreatment, egg taking and sperm separation, fertilized embryo culture, embryo transfer and blastocyst freezing. In many formal hospitals in Shanghai, there are professional IVF departments to provide comprehensive medical services and support. Through these steps, couples can successfully realize their dreams of childbearing and welcome their babies.
