Hyperactivation and Tyrosine Phosphorylation of Cryopreserved Stallion Spermatozoa in Relation to Conventional In Vitro Fertilization Blastocyst Production

open access: yesAndrology, EarlyView.
ABSTRACT Background Challenges in establishing clinical conventional in vitro fertilization (IVF) in horses include variation in sperm and oocyte quality, which can be affected by mare age. Extended preincubation of stallion spermatozoa has resulted in successful IVF.

Abnormal cleavage patterns in equine in vitro‐produced embryos lead to higher early pregnancy loss

open access: yesEquine Veterinary Journal, EarlyView.
Summary Background Despite significant advances, in vitro production (IVP) of equine embryos continues to lack standardised embryo classification criteria and is associated with increased rates of early pregnancy loss compared with in vivo‐derived blastocysts.

APOPTOTIC ANALYSIS OF CUMULUS CELLS FOR THE SELECTION OF COMPETENT OOCYTES TO BE FERTILIZED BY INTRACYTOPLASMIC SPERM INJECTION (ICSI) [PDF]

open access: yes, 2015
Oocyte quality is one of the main factors for the success of in vitro fertilization protocols. Apoptosis is known to affect oocyte quality and may impair subsequent embryonic development and implantation.

High‐Resolution Imaging Reveals Mitochondrial Protein Imbalance in Sperm of Oligoasthenospermic Men

open access: yesMolecular Reproduction and Development, Volume 93, Issue 5, May 2026.
ABSTRACT Male infertility accounts for nearly half of global infertility cases and is often linked to poor sperm quality, such as oligospermia, asthenospermia, and teratospermia. Although the exact mechanisms remain unclear, mitochondria, which are critical for ATP production and reactive oxygen species generation during fertilization, are increasingly
