In a study by Mulcahy, fifty men with reduced sperm motility applied ice packs to the scrotum at night. After treatment, both sperm density and sperm motility had at least doubled in 65 percent of the patients.

Zorgniotti and Sealfon measured scrotal temperatures in 300 sub fertile men and 30 control men. They found a statistically significant difference in temperature between the two groups (1.35 degrees Celsius), suggesting that ‘small intrinsic temperature increases may interfere with the ability of the testis to accommodate to environmental temperature stresses and so lead to abnormal semen and sub fertility.’ Zorgniotti, A. W., Sealfon, A. I., ‘Measurement of intrascrotal temperature in normal and subfertile men.’ Journals of Reproduction and Fertility, vol. 82 (1988), pp. 563-66
Laven et al studied 56 men from infertile couples. The men were categorized into two groups named ‘cool workers/sleepers’ and ‘warm workers/sleepers’ according to whether or not there was evidence of extra scrotal insulation in their lifestyles. They found a greater number of good moving sperm in the ‘cool workers/sleepers’ group, both per ejaculation and per ml. Laven, J. S., Haverkorn, M.

Jung et al found a significant increase in both sperm concentration and total sperm count as a result of nocturnal scrotal cooling. For twelve weeks, twenty infertile men used a cooling technique every night, and significant change had taken place by eight weeks.
