Cross-sectional analysis of the sperm quality was done in 4 groups of men from Zhytomyr, Kyiv, Ivano-Frankivsk, and Poltava regions, respectively, with radiation pollution territories in the range 20-550 kBq/m2. The research has elucidated the existence of correlation links between the accumulated dose of external irradiation, on the one hand, and the growth of the index of sperm deformity, pH, and the time of sperm liquefaction, on the other hand. In addition, the sperm concentration and the progressive motility are shown to decline. The long-term residence of human males on the radiation-polluted territories has been shown to result in different sperm pathologic states, namely asthenozoospermia, oligozoospermia, and teratozoospermia.
