精液粘稠度的实验和临床研究

Experimental and clinical study on human semen viscosity

我们近十多年来对生育力正常男性542名,服棉酚避孕药20例,男性不育症2919例的精液进行了精液粘稠度的研究。研究结果表明:服棉酚避孕药后精液粘度明显增高,男子不育症中,前列腺炎及特发性弱精子症和特发性畸形精子增多症病例精液粘度增高,先天性精囊发育不全或不发育者(精液果糖很低或无)精液粘度明显降低,室温增高和排精后时间延长可使精液粘度下降。治疗精液不液化不育,采用α-淀粉酶栓剂及精子洗涤、上游技术处理后精子作人工授精取得一定效果。作者认为这是两种临床可取的治疗方法。

In the past 10 years,semen viscosity(SV)in three groups of subjects was studied:542 fertile men(group A),twenty gossypol treated subjects(group B)and 2 919 infertile men (group C). A capillary tuhe,93mm in length and 0.672mm in diameter,was used for measuring the time of 0.5ml semen to pass through the capillary.The results showed that:(1)SV was significantly increased in group B and in the subjects with prostatitis,idiopathic,asthenozoospermia and teratozoospermia in group C;(2)SV was significantly decreased in patients with congenital agenesis of seminal vesicles.For infertile men with a high viscosity or non-liquefiable semen,α-amylase suppository(prepared in this Lab.)or AIH after sperm washing and swim-up may be helpful.
