Abstract Background Long‐acting gonadotropin‐releasing hormone (GnRH) agonists are commonly used for fertility control in male dogs. Their effect on testicular histomorphology has not been clarified. Objectives To elucidate the mechanisms underlying androgen withdrawal in response to long‐acting GnRH agonist deslorelin 4.7 mg treatment on testicular ...

Semen Cryopreservation in Testicular Cancer: Before or After Orchidectomy?
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.

Opioids in breast cancer: Between analgesia and modulation of tumour progression
Preclinical investigations consistently demonstrate that activation of μ‐opioid receptors and δ‐opioid receptors promote proliferation, migration, angiogenesis, epithelial‐mesenchymal transition, acquisition of cancer stem cell phenotypes, and chemoresistance.
