First application of three‐dimensional light sheet fluorescence microscopy to human testicular tumors: New perspectives in histopathology

Andrology, EarlyView.
Abstract Background Testicular tumors are among the most frequently diagnosed cancers in young men. The consequences of this diagnosis are orchiectomies, severely restricting fertility. For these young patients, a comprehensive diagnostics would be desirable, achieving a refined diagnosis and improved therapeutic patient stratification.

Initial motility and vitality predict the semen quality after long‐term cryostorage, even in patients with restricted ejaculate parameters

Andrology, EarlyView.
Abstract Background Cryopreservation of human semen is the cornerstone for preserving male fertility before gonadotoxic therapy or in cases of high variability in semen parameters. This is particular crucial in cases of severe oligoasthenoteratozoospermia (OAT), where diminished sperm counts may compromise planned intracytoplasmic sperm injection (ICSI)
