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

Andrology, 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.

Diacerein Disrupts Testicular Homeostasis: The Essential Role of Basal Cytokines in Maintaining Sertoli Cell Integrity and the Immune Microenvironment

Andrology, EarlyView.
ABSTRACT Background Pro‐inflammatory cytokines, TNF and IL‐1B, are essential for testicular homeostasis. Diacerein, an anti‐inflammatory drug, inhibits these cytokines, impairing M2 macrophages and Leydig cells (LCs). However, its impact on Sertoli cells (SCs) and M1 (CD68) macrophages remains unknown.

Loss‐of‐Function Variants in CCDC189 Cause Human Oligoasthenoteratozoospermia by Disrupting Sperm Flagellar and Acrosomal Architecture

Andrology, EarlyView.
ABSTRACT Background Oligoasthenoteratozoospermia (OAT), characterized by reduced sperm count, impaired motility, and abnormal morphology, is a major cause of male infertility with substantial genetic heterogeneity. However, the underlying genetic etiology remains unresolved in a large proportion of affected individuals.

Intrauterine Growth and Male Reproductive Health: A Follow‐up Study From the Danish National Birth Cohort

Andrology, EarlyView.
ABSTRACT Background Reduced intrauterine growth might affect male reproductive health later in life, however, existing research remain inconclusive. Objectives To investigate the association between placental weight and birthweight Z‐scores and semen characteristics, testes volume, and reproductive hormone levels in young men.

Machine Learning‐Based Prediction of Sperm Retrieval Outcomes in Patients With Klinefelter Syndrome: A Multicenter Study With External Validation

Andrology, EarlyView.
ABSTRACT Background The Klinefelter syndrome is a common genetic cause of male infertility, and testicular sperm extraction (TESE) enables sperm retrieval in a subset of affected patients. However, predicting TESE success remains challenging due to the heterogeneous clinical and endocrinological presentation of the Klinefelter syndrome.
