How to carry out the whole process of IVF? 1. Overview of IVF
IVF is an assisted reproductive technology that can help couples who cannot conceive naturally achieve their reproductive aspirations. The technology is mainly to cultivate the fertilized egg to the early stage of embryo development through in vitro fertilization and embryo transfer, and then transfer the embryo back to the mother's uterus for pregnancy. IVF technology is of great significance to solve the problem of infertility and help couples realize their dreams of fertility.
2. Basic steps of IVF
IVF mainly includes the following steps:
Step 1: Promote ovulation. The woman stimulates ovarian ovulation by receiving artificial ovulation promoting drugs or injecting growth hormone.
Step 2: Egg collection. After the ovaries are mature, after ovulation trigger drug stimulation, the doctor will use painless or general anesthesia to extract mature eggs through fine needles guided by vaginal ultrasound.
The third step: sperm collection and processing. The man provides semen samples, which are processed by centrifugation to obtain high-quality and energetic sperm.
Step 4: In vitro fertilization (fertilized egg culture). The eggs and sperm are fertilized in vitro in the laboratory, and then the fertilized eggs are cultured to the early stage of embryonic development.
Step 5: Embryo transfer. At the stage when the embryo develops to 2-6 cells, the embryo is transferred back to the mother's uterus through the guide wire or catheter, hoping that the embryo will continue to develop in the uterus.
Step 6: pregnancy monitoring. After embryo transfer, pregnancy monitoring is needed to determine whether the pregnancy is successful by means of blood test or B ultrasound.
The whole IVF process needs to comprehensively consider the couple's fertility, the doctor's medical advice and the support of laboratory technology to ensure the improvement of the success rate of IVF.
3. Common risks and complications of IVF
As an assisted reproductive technology, IVF can help couples achieve their reproductive aspirations, but it also has certain risks and complications.
Common risks include: ovarian hyper response syndrome (OHSS) caused by ovarian hyperstimulation, increased probability of multiple pregnancy, failure of embryo transfer or difficulty in implantation, increased risk of abortion, etc.
Common complications include: ovarian perforation, uterine cavity over expansion, cervical infection and endometriosis.
Therefore, before IVF, the doctor will conduct a comprehensive assessment of the couple, understand the potential risks and complications, and adjust the treatment plan according to the situation to ensure the safety and success of the operation.
4. The success rate of IVF and related hospitals
The success rate of IVF is affected by many factors, including the age of the woman, the quality of eggs and sperm, and the status of the uterus. According to statistical data, the success rate of IVF for young couples is higher, while the success rate gradually decreases with age.
In China, the gynecology and obstetrics departments of many general hospitals provide IVF technology, including Peking Union Medical College Hospital, Shanghai Changhai Hospital, Guangzhou Women and Children Medical Center, etc. These hospitals have advanced laboratory equipment and experienced expert teams to provide high-quality IVF services.
To sum up, IVF is an assisted reproductive technology that helps couples who cannot conceive naturally achieve their fertility aspirations through ovulation induction, egg collection, sperm collection and processing, in vitro fertilization, embryo transfer, pregnancy monitoring and other processes. However, IVF also has certain risks and complications, which need comprehensive evaluation and guidance from doctors. When selecting hospitals for IVF, we should consider the strength of the hospital's laboratory equipment and expert team to improve the success rate of treatment. It is hoped that through scientific efforts and reasonable choices, more couples can realize their dreams of childbearing.
