Thinning and drilling laser-assisted hatching in thawed embryo transfer: A randomized controlled trial

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

A randomized double-blind controlled study of the efficacy of laser-assisted hatching on implantation and pregnancy rates of frozen-thawed embryo transfer at the cleavage stage.

BACKGROUND Assisted hatching (AH) in fresh embryo transfer (ET) cycles increases the implantation and pregnancy rates, especially in women with a poor prognosis, repeated implantation failures and in older women. Little information exists in the literature regarding the role of AH in frozen-thawed embryo transfer (FET) cycles. METHODS Embryos were cryopreserved at the cleavage stage. On the d...

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...

Assisted Hatching for In Vitro Fertilization-Embryo Transfer: An Update

Assisted Hatching (AH) is a technique performed after In Vitro Fertilization (IVF) and involves the artificial thinning or opening of the Zona Pellucida (ZP) prior to Embryo Transfer (ET) as an attempt to improve the probability of embryo implantation. AH can be performed by embryologists via mechanical, chemical, or laser-assisted means. A few studies suggest that a larger size of ZP opening/t...
