Abstract:
The aim of this study was to systematically review the evidence for the impact of scrotal cooling on spermatogenesis. EMBASE (1980-2010) and MEDLINE (1950-Sept. 2010) databases were searched using the terms 'male infertility or subfertility or fertility', combined with a separate search of 'scrotal cooling', without any limits or restrictions. A total of eight articles met the criteria for inclusion in the study. There was insufficient evidence to draw any firm conclusions about the impact of scrotal cooling on male fertility. A positive trend of improved male fertility was however observed. There is therefore a need for well designed randomised controlled trials.
