Effect of Progesterone Supplementation on Natural Frozen-Thawed Embryo Transfer Cycles: A Randomized Controlled Trial

Effect of Progesterone Supplementation on Natural Frozen-Thawed Embryo Transfer Cycles: A Randomized Controlled Trial

BACKGROUND The transfer of cryopreserved embryos can be timed with ovulation in a natural cycle or after artificially preparing the endometrium with exogenous hormones. Progesterone is essential for the secretory transformation of the endometrium that permits implantation as well as maintenance of early pregnancy. The purpose of this study is to assess the effect of luteal phase supplementation...

The effect of luteal phase progesterone supplementation on natural frozen-thawed embryo transfer cycles

OBJECTIVE To evaluate the effect of progesterone supplementation during the luteal phase on pregnancy outcome in natural frozen-thawed embyo transfer (FTET) cycles. METHODS In this retrospective cohort study, 228 consecutive patients who underwent FTET cycles between January 2009 and September 2012 were included. One hundred forty-five patients received luteal progesterone support (P group) b...

Frozen-thawed embryo transfer cycles

In order to reduce the chance of multiple pregnancy during in-vitro fertilisation (IVF)– embryo transfer treatment, there is an increasing trend towards transferring a lower number of embryos. Surplus good-quality embryos are then transferred in frozen-thawed embryo transfer (FET) cycles. The first pregnancy after FET was reported in 1983.1 It has been estimated that in IVF programmes in which ...

effect of vitamin d insufficiency treatment on fertility outcomes in frozen-thawed embryo transfer cycles: a randomized clinical trial

background: frozen- thawed embryo transfer is an essential part of art treatment and outcomes of this procedure are associated with several clinical factors. several studies have showed an increase level of ivf outcomes in women with sufficient vitamin d. objective: whether treatment of vitamin d insufficiency can improve pregnancy rates in frozen-thawed embryo transfer cycles. materials and me...

Effect of sildenafil citrate on endometrial preparation and outcome of frozen-thawed embryo transfer cycles: a randomized clinical trial

BACKGROUND Sildenafil citrate may increase endometrial thickness and affect the outcome of frozen-thawed embryo transfer cycles. OBJECTIVE The aim of this study was to estimate the effect of sildenafil citrate on ultrasonographic endometrial thickness and pattern and to investigate the estrogen level on the day of progesterone administration, the implantation rate and chemical pregnancy rate ...
