What are the symptoms of IVF

1. Ovulation induction treatment

Since not every egg can be fertilized and not every fertilized egg can develop into a viable embryo, it is necessary to obtain multiple eggs from a woman to ensure that there are embryos that can be transferred, which requires ovulation induction treatment for women .

2. Egg retrieval

Under the guidance of B-ultrasound, the doctor uses a special egg retrieval needle to puncture the mature follicle through the vagina and aspirate the egg. Egg retrieval is usually performed under intravenous anesthesia, so the woman does not feel the pain of the puncture procedure.

3. In vitro fertilization

Sperm retrieval: While the female retrieves the eggs, the male retrieves the sperm. After the semen goes through a special washing process, the sperm and eggs are placed in a special medium in order to combine naturally. This is called conventional fertilization.

4. Embryo transfer

A few days after fertilization, a very thin embryo transfer tube is used to transfer the best embryos into the mother's uterus through the cervix. The number of transferred embryos is determined according to age, embryo quality and previous IVF outcomes, usually 2 to 3 embryos are transferred. embryo. In recent years, in order to reduce the multiple pregnancy rate, some centers choose single embryo transfer, or transfer up to 2 embryos.

Because the embryo transfer tube is thin and the doctor moves gently, the patient usually does not experience any pain.

5. Luteal Support

Women often have luteal insufficiency during the oocyte retrieval cycle due to the use of GnRH agonists/antagonists and ovulation-inducing drugs, as well as the loss of granulosa cells from oocyte retrieval, requiring progesterone and/or chorionic gonadotropin for luteal insufficiency Supplement/support. If not pregnant, stop progesterone and wait for menstruation. If pregnant, continue to use progesterone, usually until 3 weeks after the fetal heart rate is seen on ultrasound.

6. Determination of pregnancy

Serum HCG was determined 14 days after embryo transfer to determine pregnancy. Serum HCG was measured again 21 days after embryo transfer to understand the status of embryo development. Transvaginal ultrasonography was performed 30 days after embryo transfer to determine whether there was an intrauterine pregnancy and the presence or absence of fetal heartbeat.
