The Impact of Common Medications on Male Fertility: An Updated Systematic Review

Andrology, EarlyView.
ABSTRACT Background Compared with those of cytotoxic treatments, the potential effects of common medications on the fertility of men trying to conceive currently or planning to conceive in the future are less well described. The use of common medications may modify the gonadotropic axis, spermatogenesis, and epididymal maturation or alter male ...

Marginal Changes in Semen Quality Over Three Decades (1996‒2022) Among 8320 Men in the Danish Young Men Study (DYMS): Cohort Profile and Trends

Andrology, EarlyView.
ABSTRACT Background Since the 1990s, declining sperm counts and increasing testicular cancer rates have raised worldwide concern about male reproductive health, including in Denmark. This prompted a prospective population‐based study with annual surveillance of semen quality.

Androgens Modulate Tumor–Immune Interactions in Testicular Germ Cell Tumors

Andrology, EarlyView.
ABSTRACT Background The majority of testicular germ cell tumors (TGCT) are derived from the germ cell neoplasia in situ and arise after puberty in the local presence of high levels of testosterone. The seminoma subtype features a rich inflammatory infiltrate which impacts tumor progression but the role of testosterone in shaping tumor–immune ...

Pubertal Dynamics of Sertoli and Leydig Cell Dysfunction in Klinefelter Syndrome

Clinical Endocrinology, EarlyView.
ABSTRACT Context Klinefelter syndrome (KS), defined by a 47, XXY karyotype, is commonly associated with progressive testicular failure. The precise timing of Sertoli and Leydig cell dysfunction during puberty remains unclear. Objective To determine the onset and progression of testicular insufficiency during puberty in KS, and to assess whether ...
