Why should you consider ZIFT:
--The procedure involves fertilizing the egg with the sperm, followed by transferring the zygote into the fallopian tube; because of which the patient can be sure that the fertilization has happened. The only next step is travelling of the zygote down into the uterus and implantation.
-- Since the healthy zygotes amongst the numerous used for the treatment are chosen and implanted, usually there is a lower risk of multiple births compared to another procedure GIFT (Gamete Intra Fallopian Transfer, where fertilization and implantation takes within the body after mixing the egg and sperms outside).
-- The lower risk of multiple births (though cannot be completely ignored) comes as a boon; since, it causes no harm to the health of the mother, reduces chances of birth defects due to multiple babies and avoids partial abortions.
-- This is the most invasive procedure amongst all the other ARTs. Thus, apart from pain, it also involves risks of pelvic infection, side effects of general anesthesia etc.
-- Surgery related scar is a definite cosmetic disadvantage.
-- The post-surgery recovery process also is one of the disadvantages. The doctor might advise the patient to be hospitalized for 2-3 days to check further progress on implantation.
