The first step of IVF: what is IVF

In vitro fertilization (IVF) refers to the reproductive technology of artificially fertilizing eggs and sperm in vitro and transplanting the fertilized eggs into the mother's uterus to develop them into embryos. Test tube baby is an assisted reproductive technology, which is suitable for couples who are infertile due to various reasons. In the process of IVF, women's eggs and men's sperm need to be collected first. After in vitro fertilization, the sperm and egg are combined to form a fertilized egg. Next, the fertilized egg will develop for several days in the laboratory, and then select the healthiest embryo to transfer to the mother's uterus. Finally, if the embryo is successfully implanted and developed, the couple will have a chance to welcome the birth of a healthy IVF.

The first step of IVF

The first step of IVF mainly includes the following steps: 1. Ovulation promotion: Stimulate women's ovaries to produce multiple follicles by using hormone drugs to increase the chance of pregnancy. Doctors will regularly check the development of the ovary, adjust the dosage of hormone drugs, and finally determine the best time to promote ovulation. 2. Enhanced egg collection: After the eggs mature, doctors will use ultrasound guided vaginal extraction to collect the eggs. This process needs to be carried out in the operating room, usually with local anesthesia. 3. Collection of sperm: men will provide semen samples while collecting eggs. Semen samples will be processed in the laboratory to extract active sperm for in vitro fertilization. 4. In vitro fertilization: after the collection of eggs and sperm, the laboratory technicians will combine sperm and eggs for in vitro fertilization. This can be achieved by two methods: one is to directly add sperm into the culture dish and naturally combine with the egg; The other is to inject sperm from a syringe into the egg cell membrane. 5. Embryo culture: The fertilized egg will be cultured in the laboratory. The doctor will regularly check the development of the embryo and select the healthiest embryo for transplantation. 6. Embryo transfer: After the embryo has developed to a certain extent, the doctor will select the best embryo to transfer it into the mother's uterus, hoping that it can be implanted and develop into a healthy baby.

How to improve the success rate of IVF

The success rate of IVF is affected by many factors, such as age, egg and sperm quality, uterine conditions, etc. In order to improve the success rate of IVF, the following measures can be taken: 1. Select suitable patients: young women have better egg and uterus conditions, so we can consider freezing eggs before IVF for future use. In addition, it is also important to check the quality of men's sperm. 2. Improvement of IVF technology: The continuous progress of laboratory technology can improve the success rate of IVF, such as egg quality assessment and optimization of embryo culture. 3. Combined application of assisted reproductive technology: In some special cases, it can be combined with other assisted reproductive technologies, such as embryo chromosome screening, pre implantation genetic diagnosis, etc. 4. Strengthen internal environment management: women should maintain good living habits, try to avoid stress, quit smoking and drinking, pay attention to diet and nutrition, and improve physical fitness.

summary

Test tube baby is a kind of assisted reproductive technology that helps infertile couples realize their reproductive dreams. The first step includes ovulation induction, enhanced egg collection, sperm collection, in vitro fertilization, embryo culture and embryo transfer. To improve the success rate, it is necessary to select suitable patients, improve technology, combine other assisted reproductive technologies and strengthen the management of the internal environment. There is still room for improvement in the success rate of IVF, but with the continuous progress of medical technology, couples who wish to become parents have more hope.
