Semen Cryopreservation in Testicular Cancer: Before or After Orchidectomy?

Andrology, 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.

Testicular SIRT1 Loss Reveals an Aging‐Like Proteomic Landscape and Precipitates Reproductive Deterioration

Andrology, EarlyView.
ABSTRACT Background Advanced paternal age is associated with reduced male fertility and testicular dysfunction. Among the molecular regulators involved in aging, SIRT1, a NAD+‐dependent deacetylase, plays a pivotal role in maintaining oxidative balance and cellular homeostasis.

Incidence of Gonadal and Extragonadal Germ Cell Tumours in Patients With Klinefelter Syndrome

Andrology, EarlyView.
ABSTRACT Background Klinefelter's syndrome (KS; 47, XXY) is associated with an altered risk profile for malignancies compared with non‐KS males. In particular, several reports have noted a striking association between KS and extragonadal germ cell tumours (EGCTs), especially in the mediastinum, whereas the risk of testicular germ cell tumours (TGCTs ...

Broader Familial Cancer Risk in Relatives of Testicular Cancer Patients: Insights From Two Mediterranean Populations

Andrology, EarlyView.
ABSTRACT Background Familial clustering of testicular germ cell tumour (TGCT) is well‐established, whereas the risk of non‐testicular cancer among relatives remains inconsistent across studies. Objective To evaluate the overall and site‐specific cancer risk among first‐degree relatives and grandparents of TGCT patients compared to cancer‐free controls.
