What are the test tube baby procedures

The IVF process includes:

1. Ovulation induction therapy. Because not every egg can be fertilized, not every fertilized egg can develop into a viable embryo, so it is necessary to obtain multiple eggs from a woman to ensure that there are embryos that can be transferred. This requires treatment Women undergo ovulation induction therapy.

2. Egg retrieval The doctor uses a special egg retrieval needle to puncture mature follicles through the vagina under the guidance of B-ultrasound to suck out the eggs. Egg retrieval is usually performed under intravenous anesthesia, so women will not feel the pain caused by the puncture process.

3. In vitro fertilization Sperm acquisition: When a female retrieves eggs, the male retrieves sperm. After the semen undergoes a special washing process, the sperm and eggs are placed in a special culture medium in order to combine naturally. This is the so-called conventional fertilization method.

4. Embryo transfer A few days after fertilization, a very thin embryo transfer tube is used to transfer the best embryo into the mother's uterus through the cervix. Because the embryo transfer tube is very thin and the doctor moves gently, the patient usually does not have any pain.

5. Luteal support Due to the application of GnRH agonists/antagonists and ovulation-stimulating drugs, as well as the loss of follicular granulosa cells caused by egg retrieval, women usually have insufficient corpus luteum function during the egg retrieval cycle and require progesterone and/or chorionic stimulation. Gonadal hormones for corpus luteum supplement/support. If there is no pregnancy, stop progesterone and wait for menstruation. If you are pregnant, continue to use progesterone, usually until 3 weeks after the fetal heart rate is seen on the B-ultrasound.

6. Confirmation of pregnancy. Serum HCG is measured 14 days after embryo transfer to determine whether it is pregnant. Serum HCG was measured again 21 days after embryo transfer to understand embryo development. Transvaginal ultrasound examination 30 days after embryo transfer to determine whether there is an intrauterine pregnancy and whether there is a fetal heart beat.
