Objective: To study the effect of organochlorine pollution on the incidence of male infertility depending on ethnic groups. Materials and methods: Males from different ethnic groups living in rural areas which were used for tobacco- and cotton-growing, i.e. in the areas polluted by organochlorine pesticides (OCPs) were subjected to analysis. The overall number of dispensary records with confirmed diagnosis of male infertility was 1206. Of them, 751 records of the Kyrgyz outpatients, 432 - Uzbeks, 13 - Russians and 10 - Turks. The morbidity rate was calculated on the basis of the incidence rate of male infertility per 100,000 male population. The incidence rate of male infertility was calculated by conventional techniques. Results: The incidence rates of male infertility among the Kyrgyz males in tobacco-growing areas of Nookat and Uzgen districts were 33.9 and 30.33 per 100,000 male population, primary male infertility rates being 23.94 and 22.6, respectively. The incidence rates of male infertility among the Uzbek were 49.44 and 51.31, primary infertility rates being 42.4 and 46.6, respectively. In cotton-growing areas of Aravan and Kara-Suu districts, these values were as follows: 46.5 and 58.8 among the Kyrgyz, primary infertility rates being 34.4 and 46.0, respectively and 59.8 and 63.7 among the Uzbeks, primary infertility rates being 50.8 to 53.7, respectively. At the same time, the incidence rates of male infertility among the Russians and Turks were 214.4 and 97.8, respectively. Since the Russians and Turks are small population groups, the data obtained were insufficient for analysis. Conclusion: Thus, the incidence of infertility is 1.5 times higher among the Uzbek male population as compared to the Kyrgyz. The highest male infertility rate among the Uzbeks may be attributed to high pesticide loads.
