Is there a role for varicocelectomy after microdissection testicular sperm extraction? Case report and literature review

Urology Case Reports, 2019
Men with non-obstructive azoospermia (NOA) are candidates for microdissection testicular sperm extraction (microTESE). In men with NOA and varicocele, varicocelectomy has been associated with the appearance of sperm in the ejaculate.

As the field of assisted reproduction has advanced, many previously untreatable men are now biological fathers. Although finding sperm in men with obstructive azoospermia is not difficult, locating and retrieving spermatozoa in men with non-obstructive azoospermia remains a clinical challenge, largely because sperm production in these men can be patchy

Semen Cryopreservation in Testicular Cancer: Before or After Orchidectomy?

Andrology, Volume 14, Issue 5, Page 1272-1281, July 2026.
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.
