In Vitro Sperm–Epididymosomes Interaction Immediately Before Fertilization Changes Sperm Fertility Potential

Andrology, EarlyView.
ABSTRACT Background Sperm acquire fertility ability during epididymal maturation mainly in the epididymal caput and corpus, and once matured, are stored in the epididymal cauda. During storage, interactions with cauda epididymosomes (epEVs) may influence sperm fertility potential; however, the role of such interactions on sperm fertility remains ...

Semen Quality in Transgender Individuals Seeking Fertility Preservation

Andrology, EarlyView.
ABSTRACT Background Transgender individuals assigned male at birth (AMAB) may choose to preserve their fertility prior to starting gender‐affirming hormone therapy (GAHT). However, limited data exist regarding the baseline reproductive and hormonal characteristics of this population before and after GAHT.

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.
