Weighted Single‐Step GWAS Reveals Genetic Mechanisms Underlying Pregnancy Loss in Early Nellore Heifers

Animal Genetics, Volume 57, Issue 5, October 2026.
ABSTRACT Pregnancy loss (PL) affects reproductive efficiency in beef cattle, yet its genetic architecture remains poorly understood in Bos indicus populations. Here, PL was defined as failure from pregnancy diagnosis to calving, capturing a window approximately 60 days after the breeding season.

Oocyte–cumulus cell interaction: a key factor in early embryo development

Biological Reviews, Volume 101, Issue 5, Page 2265-2278, October 2026.
ABSTRACT The evaluation of oocyte competence is a fundamental step in achieving successful outcomes following assisted reproduction techniques (ART). At present, however, conventional oocyte maturation assessment is carried out by morphological observation, which is a subjective method that does not consider molecular features.

Decreased CD44v3 expression impairs endometrial stromal cell proliferation and decidualization in women with recurrent implantation failure

Reproductive Biology and Endocrinology, 2022
Background The precise pathogenesis of poor endometrial receptivity in recurrent implantation failure (RIF) remains unclear. This study was aimed at exploring the effects of different CD44 isoforms in the mid-secretory phase endometrium on endometrial ...
