Male factor-related infertility is a rising phenomenon among infertile couples. There is an increasing effort to understand the factors that affect sperm quality expressed mainly by the standard semen analysis as it is defined by WHO guidelines. The variations in sperm quality can be related to physiologic factors as racial, season, or even time of day.  A growing body of research is investigating the effects of climate change on sperm quality. It is well established that direct heat can deleteriously affect sperm quality, yet few studies have focused on ambient temperature. With warmer days and heat waves becoming more frequent, atmospheric temperature is an increasingly relevant factor. 

This study investigates the relationship between sperm analysis outcomes and temperatures in the days preceding analysis.
