The role of iron in normal and impaired testicular function

Andrology, EarlyView.
Abstract Iron plays a critical role in testicular physiology, impacting spermatogenesis, testosterone production, and overall testicular function. Iron homeostasis is maintained through systemic and cellular regulatory mechanisms, including hepcidin‐mediated systemic iron control and the iron‐responsive element/iron regulatory protein (IRE/IRP) system ...

Sperm Telomere Interactions Are Impaired in Testicular Cancer Before and After Adjuvant Therapy

Andrology, EarlyView.
ABSTRACT Background No study has yet explored telomere length or interaction in sperm nuclei of testicular cancer (TC) patients exposed to chemotherapy or radiotherapy. However, sperm telomere dynamics have emerged as a potential marker in male infertility.

Pig Seminal Plasma Extracellular Vesicles Enhance Motility During Preservation of Epididymal Spermatozoa but Impair Capacitation and IVF Parameters

Andrology, EarlyView.
ABSTRACT Background Extracellular vesicles (EVs) produced by accessory sex glands play a key role in sperm functionality, influencing motility, viability, acrosome integrity, metabolic activity, and capacitation. Most studies on the effects of EVs on spermatozoa have focused on ejaculated spermatozoa, which have already been exposed to their own native

Cryopreservation of Spermatozoa Prior and Post‐Orchiectomy in Patients With Testicular Germ Cell Cancer—Does the Timing Matter?

Andrology, EarlyView.
ABSTRACT Background Testicular germ cell cancer (TGCC) is the most frequent malignancy in young men of reproductive age. According to guidelines, semen cryopreservation should be performed prior to orchiectomy. Lack of time and local facilities as well as mental pressure are challenges in terms of fertility preservation before surgery.

Comprehensive Quantification of Oligoasthenozoospermia Induced by Obesity, Reproductive Toxicants, and Their Combination in Rat Models

Andrology, EarlyView.
ABSTRACT Background Oligoasthenozoospermia is a leading cause of male infertility and has been increasingly associated with the global surge in obesity and exposure to reproductive toxicants. Despite extensive research on each factor individually, their combined pathological effects remain poorly understood.

Parental Educational Attainment at Birth and Biomarkers of Male Fecundity: A Study From the Danish National Birth Cohort

Andrology, EarlyView.
ABSTRACT Background Low parental education is associated with poorer offspring health, but its influence on male fecundity remains unclear. Objective To study the association between parental educational attainment at birth and biomarkers of male fecundity in young men and to explore whether this association is mediated by maternal smoking in pregnancy
