中国人附睾功能指标—精浆肉毒碱研究

INVESTIGATION ON CARNITINE CONTENTS OF SEMINAL PLASMA FROM FERTILE CHINESE MEN

精浆肉毒碱90%左右来源于附睾,是附睾的功能性指标。有关实验证明附睾分泌的肉毒碱是精子在附睾中成熟的重要因素,因此是精子在附睾中成熟的重要功能性指标。本文测定了156例中国正常生育力男子精浆中的肉毒碱,并研讨了精浆肉毒碱与精液其他指标的关系。156例精液的几个主要指标: 精子存活率63.36±18.18%;精子密度111.06±90.83×10~6/ml;精子活动度:均在Ⅱ级及Ⅲ级以上;精液体积3.239±0.532ml; 精浆肉毒碱含量: 每毫升精浆肉毒碱量:239.56±105.59nmol/ml 精浆中肉毒碱总量:757.34±471.72nmol 精浆肉毒碱与精子存活率,精子密度及活动度均有相关性。

One of the important functional parameter of sperm maturation in epididymis carnitine content of seminal plasma was assayed from 156 fertile Chinese men, aged 25～35 yrs. The mean value of carnitine in seminal plasma is 239.56±105.59 nmol/ml and total carnitine content is 757.34±471.32 nmol. There exists positive relationship both bet ween sperm count and carnitine content and between sperm motility and carnitine content.
