FROZEN EMBRYO TRANSFER (FET)

Frozen Embryo Transfer (FET) is the process of embryo transplantation into the uterus after thawing frozen embryo. The patient can choose the FET date by convenient time e.g. 1-2 months after the oocyte collection date. The evidence supports FET in women more than 35 years of age are providing more pregnancy rates than FRESH embryo transfer.

Due to the inducing medication that the female takes to develop multiple of healthy ova, the huge amount of hormones generated will weaken endometrium, consequently lessening the success rate of the transfer regardless of the perfect condition of embryos. Given the circumstance, FET may not be an effective protocol. However, a number of research institutes find that FET offers better and higher chance of pregnancy because endometrial tissue is in more proper state for embryos. Therefore, the doctor will have to decide which protocol fits best for each couple.
