IVF, GIFT and ZIFT

There has been much discussion in the past about which assisted reproductive technology procedure, that being IVF, GIFT, or ZIFT, produces the best pregnancy rates. Unfortunately, GIFT or ZIFT patients can never be compared directly with IVF patients since those patients must have normal functioning tubes to have the procedure performed. IVF patients tend to be the more difficult patients either with severe male factor requiring ICSI or those who have failed due to diminished ovarian reserve.
