Abstract

Background: Infertility is a major problem all around the world. According to WHO, the rate of infertility is approximately 15% worldwide and it differ from geographical location, ethnicity and social status. Lifestyle habits, environmental and occupational hazards, physical parameters can be recognized as major risk factors which may affect male infertility. The objective of this study was to determine factors associated with male infertility in Sri Lankan context.

Methods: A cross-sectional study was conducted on 299 individuals participated for an infertility clinic at Castle Street Teaching Hospital, Colombo, Sri Lanka. Socio-demographic, occupational and environmental characteristics were collected using interviewer administered questionnaire. Semen samples were collected from each participant for laboratory investigations. Sperm concentration and motility were measured.

Results: Out of total participants, 30.1% of participants had a sperm concentration of <15×10⁶ and the sperm motility was <32% in 34.7% participants.  Older age, tobacco smokers, using tight under wears and individuals exposed to either heat or chemical hazards were identified as risk groups with low sperm concentration and low semen volume. In addition, older age, individuals using tight under wears and individuals exposed to either heat or chemical hazards were significantly associated with low or abnormal sperm mortality. Individuals having diabetes showed a significantly higher non-motility rate of sperms. Alcohol usage, betel chewing, mumps, special radiation exposure, body mass index and waist circumference were not significantly associated with semen parameters in study population.

Conclusions: Older age, tobacco smoking, wearing tight underwear, occupational exposures, and diabetes mellitus has shown a risk for the generation of poor semen parameters, which can lead to male infertility. Furthermore, it is very important to carry out extended studies regarding this problem to establish the effect of above factors.
