Long-Term Outcomes of Varicocelectomy in Children and Adolescents: Impact of Timing on Testicular Growth and Spermatogenesis

Koji Shiraishi, Satoshi Tokitaka, Yoshimasa Ban, Shintaro Oka

PURPOSE: Varicocele occurs in up to 20% of adolescent boys and is associated with impaired testicular growth and potential infertility. Although surgical indications based on testicular asymmetry are established, the optimal age for intervention remains unclear. This study evaluated the long-term associations …

HSF1/HSP25 system protects mitochondria function from heat stress and assists steroidogenesis in MA-10 Leydig cells

Shintaro Oka, Ryosuke Takii, Mitsuaki Fujimoto, Akira Nakai et autres

Heat shock response is characterized by the induction of heat shock proteins (HSPs) or molecular chaperones that maintain protein homeostasis. Heat shock transcription factor 1 (HSF1) plays a central role in heat shock response in mammalian cells. To investigate the impact of …
