The first conscious ejaculation (ejacularche) is an important event in the somatic and psychic development of boys. The aim of this study was to reveal the age at first ejaculation in Bulgarian boys and to observe the secular trend of this marker for puberty. A total of 1582 (901 from urban and 681 from rural origin respectively) gave a positive answer admitting the age in years at the first ejaculation. The mean age ± standard deviation (SD) of ejacularche was 13.27 ± 1.08 years, and the median was 13.0. It was found a significant difference between the urban (13.34 ± 1.07) and rural (13.18 ± 1.08) inhabitants in relation to the age of their remembered first ejaculation (P = 0.003). A secular trend in appearance of ejacularche was revealed when our results were compared with those from the previous studies in Bulgaria. We can suggest that in the presence of testicular volume ≥6 ml asking about ejaculation is reasonable and not superfluous. Self-reported spontaneous ejaculation can be used as an index of male pubertal timing.
首次遗精是男孩躯体和心理发育的重要事件。本研究旨在揭示保加利亚男孩首次遗精的年龄，并观察青春期这一标志的时间趋势。共有 1582 名男孩（901 名来自城市，681 名来自农村）给出了肯定的答案，承认自己首次遗精的年龄（以年为单位）。首次遗精的平均年龄为 13.27 ± 1.08 岁，中位数为 13.0。发现城市（13.34 ± 1.07）和农村（13.18 ± 1.08）居民的首次遗精年龄存在显著差异（P = 0.003）。与保加利亚之前的研究结果相比，我们的结果显示首次遗精出现的时间存在明显的趋势。我们可以假设，当睾丸体积≥6 毫升时，询问有关遗精的情况是合理的，并非多余的。自我报告的自发性射精可以作为男性青春期时间的指标。
