Comparative efficacy of varicocelectomy and intrauterine insemination in varicocoele patients with mild semen abnormalities: An observational study

Andrology, EarlyView.
Abstract Background Varicocoele is a common cause of male infertility, affecting spermatogenesis through increased testicular temperature, venous stasis, and oxidative stress. Microsurgical subinguinal varicocelectomy improves semen quality, whereas intrauterine insemination is widely used for mild male factor infertility.

Detection of germ cell neoplasia in situ and testicular cancer risk in men with testicular microlithiasis: Real world results through 10 years

Andrology, EarlyView.
Abstract Background Guidelines recommend biopsies for men <50 years with testicular microlithiasis and cancer risk factors to rule out germ cell neoplasia in situ. Limited data support this practice.
