Spawning Asynchrony and Mixed Reproductive Strategies in a Common Mass Spawning Coral

open access: yesEcology and Evolution, Volume 15, Issue 7, July 2025.
The coral Platygyra daedalea exhibits complex reproductive strategies, with individuals spawning asynchronously during a split‐spawning event and showing limited cross‐fertilisation. Genetic analysis suggests small breeding groups within larger populations, leading to low fertilisation success and reliance on self‐fertilisation.

Recommendations for the management of GnRH‐ant for ovarian stimulation in the assistant reproductive process: Benefits and harms for different ovarian response population

open access: yesClinical and Public Health Guidelines, Volume 2, Issue 3, July 2025.
Abstract Introduction: Gonadotropin‐releasing hormone antagonists (GnRH‐ant) are commonly used during controlled ovarian stimulation (COS) in the in vitro fertilization (IVF) process to prevent premature luteinization and to ensure follicles mature synchronously.

Novel ACTL7A variants in males lead to fertilization failure and male infertility

open access: yesAndrology, Volume 13, Issue 5, Page 1117-1126, July 2025.
Abstract Background Total fertilization failure occurs in 1%–3% of all intracytoplasmic sperm injection cycles. Genetic defects are found to be crucial causes responsible for total fertilization failure after intracytoplasmic sperm injection. However, the reported genes only elucidate a small proportion of total fertilization failure cases, and more ...

CRISPR/Cas9‐mediated genome editing reveals seven testis‐enriched transmembrane glycoproteins dispensable for male fertility in mice

open access: yesAndrology, Volume 13, Issue 5, Page 1251-1260, July 2025.
Abstract Background Mammalian fertilization is mediated by multiple sperm acrosomal proteins, many of which are testis‐enriched transmembrane glycoproteins expressed during spermiogenesis (e.g., Izumo sperm‐egg fusion 1, Sperm acrosome associated 6, and Transmembrane protein 95).
