Testicular steroidogenesis is decreased by hyperthermia in old rats. - PubMed - NCBI
"Hyperthermia significantly decreased the testicular testosterone level in old male rats and significantly lowered the StAR protein level. These data imply that frequent hot baths might impair testicular steroidogenesis, especially in old men."
Effects of local testicular heat treatment on Leydig cell hyperplasia and testosterone biosynthesis in rat testes. - PubMed - NCBI
"Heat treatment reduced serum and testicular testosterone concentrations. Consistent with this finding, heat stress downregulated two enzymes required for testosterone biosynthesis, namely cytochrome P450, family 17 (CYP17) and steroidogenic acute regulatory protein, in Leydig cells. Together, the results suggest that testicular heat leads to Leydig cell hyperplasia and a reduction in testosterone biosynthesis in adult rat testes."
