Abstract

Summary— Two new techniques for measuring deep scrotal temperature are described. Paraplegic men in wheelchairs have deep scrotal temperatures averaging about 0.9°C higher than normal sitting men, and those whose scrotal temperatures are very high usually lack motile spermatozoa. In the author, deep scrotal temperatures at constant air temperature are 0.5°C lower wearing boxer shorts than wearing Y-fronts, and 1.2°C lower wearing scrotal slit underpants than wearing boxer shorts; they are 1.6°C lower sitting with thighs apart than sitting with thighs together, and 0.5°C lower running than sitting with thighs apart. From such observations, means of lowering paraplegic deep scrotal temperatures can be designed.
