Article Synopsis
  • - The study focuses on understanding the reasons behind pregnancy loss after transferring a healthy (euploid) embryo, as such losses are often linked to chromosomal issues, but those aren't the main cause here.
  • - Researchers analyzed pregnancy outcomes from single euploid embryo transfers between January 2017 and March 2020 and found certain factors, like previous pregnancy loss history and embryo quality, that were significantly different between those who experienced total pregnancy loss and those who achieved live births.
  • - Although morphokinetic analysis of embryo development showed no major differences statistically, the group that had pregnancy losses had a higher occurrence of uneven blastomeres during early division, suggesting that evaluating clinical and embryological data could help improve patient outcomes and lead

Purpose: This study aimed to investigate which patient and cycle characteristics may affect the number of mature oocytes and cryopreservable blastocysts in the GnRH analog trigger cases.

Methods: This was a retrospective cohort study of 2749 GnRHa trigger cycles in patients at risk of OHSS, including a group of PGT patients, between 2011 and 2020 at Istanbul Memorial Hospital, ART and Reproductive Genetics Center. Patient and cycle characteristics were evaluated using the Generalized Linear Mixed Model (GLMM).

Purpose: To evaluate whether preimplantation genetic testing for aneuploidy (PGT-A) is beneficial for patients who have only one blastocyst available for biopsy or transfer.

Methods: This retrospective study was based on 1126 single blastocyst PGT-A and 938 non-PGT-A cycles, a total of 2064 ART cycles which resulted in a single good quality blastocyst in women between 20 and 45 years old. The PGT-A group had 225 single euploid embryo transfer cycles and the non-PGT-A group had 938 single blastocyst embryo transfer cycles.

Background: Before 2010, there were no regulations in Turkey regarding the number of embryos to be transferred in one cycle. In March 2010, regulations restricting this number were implemented by the Turkish Ministry of Health. These specify the transfer of a maximum of one embryo in the first and second cycles and a maximum of two embryos in subsequent cycles in women aged < 35, and a maximum of two embryos in women aged ≥35 in any one cycle.
