A survey on infertility in men and its relation to risk factors in selected provinces of Iran.

OBJECTIVE

Infertility in men cause significant morbidity and mortality, unfortunately there is not enough information about it due to the lack of a registry in the country. The purpose of this study was to determine the frequency of infertility in men and its association with risk factors.

METHODS

This cross-sectional study used data from a nation-wide project on reproductive morbidities among males in Iran in 2007. 2,293 men aged 25-60 years were selected from four provinces across the country including, Golestan Province in the North, Hormozgan Province in the South, Kermanshah Province in the West, and Isfahan Province by cluster sampling scheme. Then, we determined the frequency of infertility in married men, and related risk factors such as smoking, infection, trauma, etc.

RESULTS

Of the 2,293 men interviewed, 2,076 were married, 78 were infertile; current primary and secondary infertility was estimated at 3.75%. The incidence of infertility in urban areas was significantly higher than in rural areas (p value<0.003), and finally the clinically male infertility was estimated at 2%.

CONCLUSIONS

We need to explain that this project was a cross-sectional study. Therefore, it is recommended that more studies be conducted for accurate estimates of infertility in Iranian men.
