In vitro fertilization (IVF) is an assisted reproductive technology that uses the husband's sperm and the wife's egg to fertilize it in a laboratory. After the embryo is formed, the embryo is returned to the uterus for implantation and a normal pregnancy begins. IVF has a relatively high success rate for the case of the wife with blocked and damaged fallopian tubes or congenital anomaly, endometriosis, etc., and the husband has weak sperm, heterosexuality. spermatogenesis or immobility...Besides, the age of the wife is one of the important factors determining the high or low success rate of IVF. Accordingly, the younger the wife, the better the number and quality of eggs, if the eggs are combined with healthy sperm, the more good embryos are formed, thereby leading to a higher chance of successful embryo transfer. .

When going to fertility clinics to perform IVF, the couple will be examined and have the following tests: gynecological examination, Pap's, ultrasound, basic blood tests (GS-Rh, HIV, HbsAg, BW...), semen analysis...

Depending on the specific case, the doctor will let the wife perform ovarian stimulation according to the appropriate regimen. Duration of treatment varies but ranges from 3-7 weeks. During ovarian stimulation, the doctor will monitor the eggs in the wife's body by ultrasound of the follicles and blood tests (3-6 times) and adjust the ovarian stimulation medication according to each response. People. When the eggs are satisfactory, the doctor will prescribe hCG injection for the wife to prepare for egg retrieval. About 36-40 hours after hCG injection, the wife needs to fast and go to the hospital in the morning to conduct egg retrieval.Pre-anesthesia before IVF is done with an anesthesiologist (general health check and allergy history) because egg retrieval is done under light anaesthesia, which is essential and mandatory for all anesthetic resuscitation operations, in order to prevent and limit possible complications during anaesthesia.
After the pre-anesthesia examination, the wife is anesthetized during IVF and local anesthesia (uterine anesthesia) to aspirate eggs through the vagina, under the guidance of transvaginal ultrasound. The aspiration procedure takes 5-15 minutes. The wife needs to stay in the hospital to monitor her pulse and blood pressure for at least 2-3 hours after the egg retrieval steps are completed.
