Sir,

I have read with great interest the publication of Björndahl et al. (2006)Go dealing with a device which would afford a home fertility-sperm test to the man who questions his own fertility. The device seemed to be rather complicated, and the usefulness and marketability will remain to be seen. I would like to make one comment. It looks like the regulation of temperature has quite a bit of variability. The article quotes ‘37 ± 3°C’. I would be rather concerned that a high temperature around 40°C may have a significant effect on the survival and motility of the sperm. It has been well documented that even occasional exposure of the testicles to high temperatures may significantly affect the quality of sperm produced. Thus, a variation from 34 to 40°C could have a significant effect on the motility of the sperm, even realizing that it is not meant to be used for insemination or any other non-laboratory purposes. The authors may be well advised to compare the parameters of a sample left at well-controlled temperatures of 34, 37 and 40°C.
