Ejaculatory disorders are one of the most frequent sexual dysfunction. To study this problem in different climatic regions, we made a population-based trial with participation of 543 Russian men (149 from the south of Russia, 394 from Siberia). Correlation of ejaculatory disorders with IELT duration, a testosterone level, comorbid chronic prostatitis was estimated. We found that 59.2% of young men had normal ejaculation but only 20% of men over 50 years of age. In the latter group of patients delayed ejaculation predominated. 43.6% of the southerners and 33.5% of the Siberians had premature ejaculation, and 6.1 and 16.9%--delayed ejaculation, respectively; 26.7 and 31.2% were hypogonadal, respectively. Ejaculation was normal in 74.6% men with a normal testosterone level. Hypogonadal patients had premature ejaculation in 48.2% cases, delayed ejaculation in 28.3%. Of the total 543 men, 67.2% had chronic prostatitis. Only 46% of patients with chronic prostatitis had normal ejaculation, 43.3% had premature ejaculation and 10.7% had delayed ejaculation. Thus, in cold climate delayed ejaculation occurs more often, in the South premature ejaculation predominates. A low testosterone level as well as chronic prostatitis resulted in ejaculatory disorders. There are significant differences in ejaculation between young and old men, whose living in the South and Siberia, eugonadal and hypogonadal. Therefore, when characterizing a copulative act as "normal" it is necessary to take into account age, comorbidity, region of living and other factors.
射精障碍是最常见的性功能障碍之一。为了在不同气候区域研究这一问题，我们开展了一项基于人群的试验，有543名俄罗斯男性参与（149名来自俄罗斯南部，394名来自西伯利亚）。评估了射精障碍与阴道内射精潜伏期（IELT）时长、睾酮水平、合并慢性前列腺炎之间的相关性。我们发现，59.2%的年轻男性射精正常，但50岁以上男性中只有20%射精正常。在后一组患者中，射精延迟占主导。43.6%的南方人和33.5%的西伯利亚人有早泄，分别有6.1%和16.9%有射精延迟；性腺功能减退者分别为26.7%和31.2%。睾酮水平正常的男性中有74.6%射精正常。性腺功能减退患者中48.2%有早泄，28.3%有射精延迟。在总共543名男性中，67.2%患有慢性前列腺炎。慢性前列腺炎患者中只有46%射精正常，43.3%有早泄，10.7%有射精延迟。因此，在寒冷气候下射精延迟更常见，在南方早泄占主导。低睾酮水平以及慢性前列腺炎会导致射精障碍。在南方和西伯利亚生活的年轻与老年男性、性腺功能正常与减退者之间，射精情况存在显著差异。所以，在将性交行为描述为“正常”时，有必要考虑年龄、合并症、居住地区等因素。
