Single-cell analysis of developing and azoospermia human testicles reveals central role of Sertoli cells

open access: yesNature Communications, 2020
Non-obstructive azoospermia affects 1% of men. Here, authors perform single-cell transcriptomic analysis of human testicular cells from healthy donors and non-obstructive azoospermia patients and find that inhibition of Wnt signaling promotes the ...

Semen Cryopreservation in Testicular Cancer: Before or After Orchidectomy?

open access: yesAndrology, EarlyView.
ABSTRACT Background Fertility preservation in patients with testicular cancer remains a clinical priority, yet the optimal timing for sperm cryopreservation—before or after orchidectomy—remains a matter of debate. Objectives The aim of this study was to determine the optimal timing for semen cryopreservation and the best‐quality sample for ART.

Trends in Semen Quality: A Contrasting Perspective From a Single‐Centre Review in Ireland

open access: yesAndrology, EarlyView.
ABSTRACT Introduction Male factor contributes up to half of infertility cases and reports of a global decline in semen quality raise concern for the future of male reproductive health. However, fertility trends can vary by region and population. Interpreting local patterns is crucial for understanding the true trajectory of male fertility.

Impact of Chemotherapy on Sperm Functional Characteristics in Patients With Testicular Germ Cell Tumours

open access: yesAndrology, EarlyView.
ABSTRACT Background Testicular germ cell tumours (TGCT) are the most common malignancies among young men and represent a major threat to reproductive health. Both the disease itself and oncological treatments, particularly chemotherapy, can compromise spermatogenesis and semen quality.
