Aim of study (acc. to author)

A study was conducted in Poland to examine the association between severals factors (e.g. age, BMI, mobile phone use, smoking, occupational and life stress) and male sperm DNA damage measures.

Further details

Sperm DNA damage was assessed by DNA fragmentation index and DNA stainability index (percentage of immature sperms).
Remark EMF-Portal: It is not clear which aspects (calling time, playing games or texting, usual location of the device while talking and carrying) should be investigated.

Endpoint/type of risk estimation

reproductive effects and pregnancy outcomes: sperm damage (DNA fragmentation)

Type of risk estimation:

prevalence

Exposure

- mobile communications
- mobile phone
- personal

Assessment

questionnaire: mobile phone use

Exposure groups

Group	Description
Reference group 1	mobile phone use: 0 - 5 years
Group 2	mobile phone use: 6 - 10 years
Group 3	mobile phone use: 11 - 25 years

Population

Group:
- men
Age: 22–45 years
Characteristics: men attended infertility clinic with normal oder slight reduced semen concentration.
Observation period: 2008 - 2011
Study location: Poland (Lodz)
Data source: parent study on environmental factors and male infertility

Study size

Type	Value
Total	344
Evaluable	286

Statistical analysis method:

linear regression

(adjustment:

age
past diseases, duration of infertility, time of sexual abstinence, stress, smoking, alcohol consumption, BMI

)

Results (acc. to author)

A significant association between mobile phone use for more than 10 years as well as obesity and the percentage of immature sperms was observed. Higher levels occupational stress and age increased the DNA fragmentation index.
The authors concluded that stress, age and lifestyle factors such as obesity and mobile phone use may affect sperm DNA damage.
