Pregnancy Loss, Frozen Embryo Transfer
Substituted Frozen Embryo Transfer Cycles With GnRH-agonist Supplementation
The aim of this study is to compare two FET protocols by modifying the substituted FET cycle in order to maintain a higher ongoing positive pregnancy rate and thus reduce the early pregnancy loss.

Frozen Embryo Transfer
Assessment of Endometrial and Sub-endometrial Vascularity Before and After PRP Infusion in Frozen Embryo Transfer Cycles
A good quality embryo and receptive endometrium are important aspects in achieving optimal outcomes in assisted reproductive treatment (ART). Endometrial thickness is an important marker of uterine receptivity.
