Sperm Telomere Interactions Are Impaired in Testicular Cancer Before and After Adjuvant Therapy

Andrology, EarlyView.
ABSTRACT Background No study has yet explored telomere length or interaction in sperm nuclei of testicular cancer (TC) patients exposed to chemotherapy or radiotherapy. However, sperm telomere dynamics have emerged as a potential marker in male infertility.

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.

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 ...

Contact Activation Is Alleviated by Testosterone Replacement Therapy in Klinefelter Syndrome: Evidence of Hormonal and Metabolic Modulation

Andrology, EarlyView.
ABSTRACT Background Klinefelter syndrome is associated with a markedly increased risk of venous thrombosis. While hypogonadism and metabolic dysfunction are known contributors, the role of the contact activation system in Klinefelter syndrome remains unexplored.
