ancora sulla fertilità

E' stato appena pubblicato uno studio (meta analisi) che riprende vari similari ricerche sulla qualità dello sperma per effetto delle radiofrequenze.
Si conclude che gli effetti possono essere diversificati ma che esiste una chiara relazione tra uso del cellulare e la qualità degli spermatozoi.

... purtroppo queste note sicuramente non arrivano ai ragazzi che hanno spesso l'abitudine di infilare il cellulare nella tasca anteriore dei jeans ...!!     

Questo è un invito a fare educazione sanitaria !.

Mobile phones affect multiple sperm quality traits: a meta-analysis.

As mobile phone usage is growing rapidly, there is a need for a comprehensive
analysis of the literature to inform scientific debates about the adverse effects
of mobile phone radiation on sperm quality traits. Therefore, we conducted a
meta-analysis of the eligible published research studies on human males of
reproductive age. Eleven studies were eligible for this analysis. Based on the
meta-analysis, mobile phone use was significantly associated with deterioration
in semen quality (Hedges's g = -0.547; 95% CI: -0.713, -0.382; p < 0.001). The
traits particularly affected adversely were sperm concentration, sperm
morphology, sperm motility, proportion of non-progressive motile sperm (%),
proportion of slow progressive motile sperm (%), and sperm viability. Direct
exposure of spermatozoa to mobile phone radiation with in vitro study designs
also significantly deteriorated the sperm quality (Hedges's g = -2.233; 95% CI:
-2.758, -1.708; p < 0.001), by reducing straight line velocity, fast progressive
motility, Hypo-osmotic swelling (HOS) test score, major axis (µm), minor axis
(µm), total sperm motility, perimeter (µm), area (µm (2)), average path velocity,
curvilinear velocity, motile spermatozoa, and  acrosome reacted spermatozoa (%).
The strength of evidence for the different outcomes varied from very low to very
high. The analysis shows that mobile phone use is possibly associated with a
number of deleterious effects on the spermatozoa.
