Исследование проводили на сперматозоидах человека из 14 образцов эякулята, полученных общепринятым способом. Подвижность и жизнеспособность оценивали по рекомендациям Всемирной организации здравоохранения при увеличении в 400раз. Из каждого образца эякулята после разжижения отбирали по 1 мл для опыта и контроля. Опыт заключался в добавлении пирувата в пробирку с эякулятом до достижения концентрации 1 ммоль.</p></sec><sec><title>Результаты</title><p>Результаты. Уровень исходной подвижности сперматозоидов соответствовал нормозооспермии. Доля сперматозоидов с прямолинейным движением (категорий А и B) увеличилась на 24, 67 и 84 % через 30, 60 и 120мин эксперимента. Доля сперматозоидов с непрямолинейным движением (категории С) и общая доля подвижных сперматозоидов существенно не изменились в этот период. Количество жизнеспособных сперматозоидов на протяжении опыта статистически значимо не изменилось.</p></sec><sec><title>Заключение</title><p>Заключение. Выявлена способность пирувата повышать подвижность сперматозоидов человека in vitro.</p></sec></abstract><trans-abstract xml:lang="en"><p>The study objective is to investigate the biological effect of energy substrate (pyruvate) on human sperm motility in vitro.</p><sec><title>Materials and methods</title><p>Materials and methods. The study was conducted using human sperm from 14 ejaculate samples obtained by the standard method. Motility and viability were evaluated per the World Health Organization guidelines under 400x magnification. After dilution, 1 ml was sampled from the ejaculate for the experiment and control. The experiment consisted of addition of pyruvate to the test tube with the ejaculate in final concentration of 1 mmol.</p></sec><sec><title>Results</title><p>Results. The level of initial sperm motility corresponded to normozoospermia. The percentage of progressive motile sperm increased by 24, 67 and 84 % after 30, 60 and 120 min of the experiment. The percentage of non-progressive motile sperm and total percentage of motile sperm showed no significant change during this time period.
