Developmental biology
Researchers from Newcastle University have conducted a study to investigate the effects of high non-esterified fatty acids (NEFAs) on reproduction in dairy cattle, particularly during in vitro fertilisation (IVF). The study found that high NEFA concentrations can impair pre-implantation embryo development, potentially via effects on both the oocyte and spermatozoon.

Clinical trials
Researchers at the University of Health Sciences in Ankara, Turkiye, have made a significant discovery in clinical trial research. By analyzing serum b-hCG values, they found that these values can predict live birth in both fresh and frozen embryo transfers with a sensitivity of 75% and a specificity of 72%
Clinical trials
New research from Sahlgrenska University Hospital in Gothenburg, Sweden, has raised concerns about the effectiveness of time-lapse imaging (TLI) systems in improving in vitro fertilization (IVF) outcomes. Despite significant investment by IVF clinics, the technology has shown inconsistent results, leading to uncertainty about its benefits. The study, published in BMJ
