• Reversible Repeated sauna sessions lowered sperm count and motility; the measures returned toward baseline after the heat stopped. Garolla et al., Human Reproduction, 2013.
• ~50% Sperm counts among Western men fell roughly 50% over about four decades. Heat is one of the few exposures you can reduce day to day. Levine et al., Human Reproduction Update, 2017.
