Summary
There are three main cycle regimens used for endometrial preparation for frozen embryo
transfer（FET）: natural cycles (NC) with/without ovulation triggering, hormone replacement
therapy cycles (HRT) in which the endometrium is artificially prepared by estrogen and
progesterone hormones with/without a gonadotrophin releasing hormone agonist (GnRH-a) down
regulation, and ovulation induced cycles (OI) in which follicular development is supported
with increasing doses of gonadotrophin hormones and ovulation is induced. At present, there
is still no sufficient evidence that which kind of FET cycle regimen to plan more advantage.
The purpose of this study was to compare the pregnancy outcome of NC-FET to that of HRT-FET
in women with regular cycles.
