Medical/biological Study (observational study)

Effect of cell phone usage on semen analysis in men attending infertility clinic: an observational study. med./biol.

PubMed Entry

Journal web site

Aim of study (according to author)
To assess the effects of cell phone use on various sperm parameters among patients undergoing infertility evaluation at a male infertility clinic.
Background/further details:
361 men were divided into four groups according to their cell phone use: group 1: no use; group 2: <2 h/day; group 3: 2-4 h/day; and group 4: >4 h/day.

Endpoint

• effects on reproductive ability: semen quality

Exposure
mobile phone
detailled exposure not extractable (no details given in article)

Exposed system:
human

Methods
Endpoint/Measurement parameters/Methodology

• effects on reproductive ability: sperm parameters (volume, liquefaction time, pH, viscosity, sperm count, sperm motility, viability, morphology)

Main outcome of study (according to author)
The use of mobile phones decreased the semen quality in men by decreasing the sperm count, sperm motility, viability, and the percentage of sperms with normal morphology. The decrease in sperm parameters was dependent on the duration of daily exposure to mobile phones.
