Summary
The transfer of frozen-thawed embryos can be performed in a natural ovulatory cycle or in a
hormonally manipulated cycle with a comparable pregnancy rate of 15%-20% per ET. When a
hormonally modulated ET cycle is scheduled,an artificial endometrial preparation is carried
out using estrogen stimulation followed by a concomitant progesterone treatment. Two
progestative drugs are currently used in conventional IVF treatment, Utrogetan and
Endometrin. Although Endometrin has been be efficiently used to support the luteal phase
after embryo transfer in IVF cycles, currently, there is no study that assess its efficacy
for clinical use in frozen-thawed ET cycles. The present study aims to compare the outcome of
frozen thawed ET cycles when either Endometrin or Utrogestan are used as the progestative
substitution in an artificially prepared endometrium.
