Process of second-generation IVF
The second-generation test tube baby, also known as assisted reproductive technology (ART) baby, refers to the baby who is assisted in pregnancy through in vitro fertilization (IVF). This technology, which originated in the 1970s, has developed into a relatively mature technology and is widely used worldwide. The process of second-generation IVF will be introduced in detail below.
1. Preliminary assessment and inspection
Before the second generation of IVF, the doctor will make a preliminary evaluation and necessary examination for both the husband and wife. These tests include the woman's ovary, uterus and fallopian tube, and the man's semen. Through these examinations, doctors can preliminarily judge the fertility potential of both husband and wife and the appropriate treatment plan.
If both parties meet the conditions for second-generation IVF, the doctor will further evaluate the female's ovarian function, endometrial thickness, male sperm vitality and other indicators to determine the specific treatment plan.
2. Ovulation induction and egg collection
Before the second-generation IVF, the woman needs ovulation induction treatment to increase the number of mature eggs. Ovulation induction therapy is generally performed by drug injection, and the doctor will adjust the dosage of the drug according to the woman's ovarian function.
During drug treatment, doctors will conduct regular ultrasound examination and blood test to monitor the development of follicles and ovarian function. When the follicle develops to the appropriate size, the doctor will arrange an egg collection operation.
The egg collection operation is usually completed in the hospital. Through the ovarian puncture technology guided by transvaginal ultrasound, the doctor stores the collected eggs in the culture dish for the next step.
3. Fertilization and embryo culture
The collected eggs will be inseminated with sperm in vitro. Sperm can come from both husband and wife or donated sperm. After fertilization, the doctor will culture the fertilized eggs in a petri dish to promote embryonic development.
Embryo culture usually lasts for 3 to 5 days. Doctors will evaluate the development of embryos every day and select the healthiest embryos for transplantation or cryopreservation. Before embryo transfer, doctors may conduct embryonic genetic screening to exclude chromosome abnormalities and genetic diseases.
4. Embryo transfer and pregnancy observation
Embryo transfer is the last step of the second generation IVF process. The doctor places the selected embryo into the uterus through vagina. This process generally does not require anesthesia, and only a little discomfort will be felt.
After transplantation, the woman needs to continue to use progesterone and other drugs to assist embryo implantation and growth. About 10 to 14 days later, the doctor will conduct a blood test to determine whether pregnancy. If the pregnancy is successful, the doctor will continue to monitor and provide appropriate care until the pregnant woman is transferred to the obstetrics and gynecology department.
summary
The process of second-generation IVF usually goes through several steps, such as preliminary evaluation and inspection, ovulation induction and egg collection, fertilization and embryo culture, as well as embryo transfer and pregnancy observation. This technology has brought hope to infertile couples. However, each couple's situation is unique, and the specific treatment plan needs to be formulated according to their personal conditions. If you have needs, it is recommended to consult a regular hospital or professional doctor to get the most appropriate treatment plan and care.
