A surprising outcome: my fertility health improved by XX% after XX days of sauna.

Didn’t expect that to happen. 

Sauna is not known to improve fertility health. Perhaps it was the icing of my boys?

Protocol:
+ Dry sauna. Temperature: XXX °F (93° C)
+ Daily, 20-min sessions
+ Ice pack on groin area

The result:
 My highest numbers to date:
 + Total Motile Count: XXX million (6x fertility baseline)
 + Concentration: XXX million/mL
 + Motility: XX%
 + Morphology: XX% normal
 + Volume: XXXX mL
 + Total Count: XXX million
