The frozen embryo transfer (FET) cycle refers to the time you decide to implant the embryo into the uterus and try for a pregnancy. When compared with a fresh cycle, stimulated with in vitro fertilization, FET has plenty of benefits. Many couples choose this method because it requires less medication. Instead, an FET cycle uses estrogen and progesterone to prepare the uterus for a potential pregnancy. Other reasons opt for FET include:
No need for anesthesia
No additional egg retrieval procedure
Less emotional and mental stress
Have control over the number of embryos transferred
