The thermal impact described by the creator is based on solid evidence: an observational and experimental study conducted by Dr. Sheynkin (2005) indeed demonstrated that using a laptop on the thighs rapidly increases the temperature of the intimate area, both due to heat from the device and the closed-leg posture. Regarding the impact of waves, a meta-analysis from the University of Exeter (Mathews et al., 2014) also confirms a decrease in sperm vitality and motility in mobile phone users. As for the experiment involving sperm exposed next to a device, it refers to an in vitro study (Avendaño et al., 2012) that observed a decrease in motility and DNA alterations. Nevertheless, transposing this in vitro study to real life warrants nuance, as our body tissues provide a natural barrier that a sample exposed directly in a dish lacks. In fact, a large prospective cohort study (PRESTO cohort, 2021) did not identify a significant overall decrease in fertility in men carrying their phone in their front pocket. It is therefore very relevant to limit direct thermal exposure to this area as a simple precaution for well-being, without overstating the daily effect of waves.
