Abstract Background Vitrification procedures decrease intracytoplasmic lipid content and impair developmental competence. Adding fatty acids (FAs) to the warming solution has been shown to recover the lipid content of the cytoplasm and improve develo

Abstract This study aimed to examine the viability of human blastocysts after warming with fatty acids (FAs) using an in vitro outgrowth model and to assess pregnancy outcomes after a single vitrified-warmed blastocyst transfer (SVBT). For the experi

Abstract Background Human embryos express the prolactin (PRL) receptor at the morula and blastocyst stages. Treatment with PRL from cleavage to the blastocyst stage improves blastocyst outgrowth on fibronectin-coated dishes. However, whether post-war

Abstract Background Letrozole treatment is considered an effective option in endometrial preparation for frozen embryo transfers in patients with ovulation disorders or irregular menstruation; however, the effectiveness of letrozole-induced endometri

Background and Aims: Generally, the performance of deep learning models is improved by increasing the size of the training dataset. However, to the best of our knowledge, there has been no study on the effect of increasing training data on the perfor

Background and Aims: In recent years, preimplantation genetic testing (PGT) has frequently involved a trophectoderm (TE) biopsy at the blastocyst stage, followed by vitrification. However, the factors influencing the viability of biopsied blastocysts

Background and Aims: With the exception of chromosome segregation errors, the molecular and biochemical mechanisms responsible for advanced maternal age (AMA)-related reduced embryo developmental competence remain unclear. In women of AMA, the blasto

BACKGROUND: Although a recent study reported that the pregnancy outcomes in the first trimester were more correlated with endometrial thickness on the day of the trigger than with endometrial thickness on the day of single fresh-cleaved embryo transf
