对107例男性进行精液分析并测定其精浆催乳素(PRL)浓度,精子活动率和精子密度正常男性的精浆PRL为11.53±5.36ng/ml,与精子活动率正常而少精子的男性相比(13.06±4.62ng/ml),两组间无显著性差异(t=0.91,t>0.2);而精子密度正常、正常精子活率组和低活率组相比,低活率组的精浆PRL水平(17.24 ±5.86ng/ml)明显增高(t=4.15,P<0.001).相关分析表明精浆PRL与精子活动率呈负相关(r=-0.38,P<0.001);与精子密度亦呈负相关(r=-0.37,P<0.001).49例受试者取精液前抽血测定血清PRL水平,精浆PRL水平与血清PRL无关(r=0.204,P>0.1).
Semen analysis of 107 males and their PRL concentrations of seminal plasma prolactin (PRL), sperm motility and sperm density were normal in men with a PRL of 11.53 ± 5.36 ng / ml, similar to sperm motility and sperm motility (13.06 ± 4.62ng / ml), there was no significant difference between the two groups (t = 0.91, t> 0.2); while the normal sperm density, normal sperm motility group and low survival rate group, The level of PRL in seminal plasma (17.24 ± 5.86 ng / ml) was significantly higher (t = 4.15, P <0.001). Correlation analysis showed that PRL of seminal plasma was negatively correlated with sperm motility (r = -0.38, (R = -0.37, P <0.001) .49 subjects took blood before taking semen to measure serum PRL level, and seminal plasma PRL level had no correlation with serum PRL (r = 0.204, P> 0.1).
