Abstract
Introduction: About 50% of causes of infertility are partly or completely attributable to male factors. Some factors affecting men's infertility are related to genetic and environmental factors. The aim of this study was to examine demographic characteristics of infertile men.
Methods: This was a descriptive study was conducted on200 infertile men who were referred to Shariati Hospital Infertility Clinic, Tehran, Iran, November 2010 to May 2011. Data were collected by face-to-face interviews based on a questionnaire. Spermiogram test was performed for all patients by a laboratory manual method. Data were analyzed using SPSS software version 16 and t-test, chi-square and linear regression tests. P value less than 0.05 was considered significant.
Results: Mean age of patients was 34.1±5.7 years. Mean number of years after marriage was 3.6±1.3 years.Most patients (68%) were self-employed and the majority of them were dealt with chemicals in their jobs.The risk of diabetes, mumps and varicocele were higher in workers than patients who had official jobs. Sperm analysis showed that the most common problem in infertile men was decreased sperm motility.So that,sperm motility was lower than 40% in 162 participants (81%). 84 cases (42%) had a decrease in sperm count and 39 patients of them (46%) were azoospermic.
Conclusions: No relationship exists between body mass index, occupational status, smoking, history of any disease and sperm parameters in infertile men.
