Following are the steps involved in the procedure:
Ovarian stimulation: Hormonal medications are administered soon after the 2nd day of the cycle to increase ovulation. As a result of which multiple eggs are produced . The maturation of follicles is continuously monitored.
Egg aspiration: Once the eggs are matured, the doctor extracts/aspirates about 8 -15 eggs from the follicles using a catheter.
Fertilization: The sperm sample and the extracted ovaries are mixed in the petri dish and monitored for fertilization. After 24 hours of this procedure the fertilized eggs called zygotes are produced.
Surgery: Unlike IVF where the embryo is placed in the uterus using catheter, ZIFT involves a minimally invasive laparoscopic surgery after administering a general anesthesia. About 1-5 zygotes are inserted into the fallopian tube. Though it involves surgical procedure, in most of the cases this is an outpatient procedure.
Implantation: Once the body's environment accepts the zygote, the zygote travels down the uterus and implants itself to the uterine wall there by establishing pregnancy. The onset of pregnancy can be tested two weeks after the procedure.
