Conception rate according to the size and location of corpus luteum and coexistent follicle before embryo transfer in Hanwoo.

ABSTRACT: The size and location of the corpus luteum and the presence of coexistent follicles are crucial factors in synchronizing recipients and determining the suitability for embryo transfer. However, there has been a recent decline in conception rates after embryo transfer, which is attributed to environmental pollution, uterine inflammation, ovarian cysts, and other factors. Therefore, we conducted experiments to establish a novel criterion for successful embryo transfer assessment. To assess the suitability for embryo transfer one day before transfer, we conducted ultrasound examinations equipped with a vaginal probe to evaluate the corpus luteum and coexistent follicle. We found that instances with corpus luteum and coexistent follicles (diameter: > 10 mm) constituted the majority (69.7%) of
