精索静脈瘤の臨床的研究 : (1)精液所見と睾丸所見について

Abstract

(1)精索静脈瘤の程度と精子濃度, 精子運動率と患側睾丸のscore countは相関しなかった.(2)精索静脈瘤に対する手術療法により, 精子濃度と精子運動率が改善する傾向をみたが, 両者共改善例は全症例の40%であった.(3) 80%以上の例で, 精索静脈瘤患者の左睾丸は右睾丸よりも小さかった.(4)ほとんどの例で, 両側睾丸のscore countは低下し, 睾丸重量が10g以下のものでは, score countは高度に低下していた.また, 左睾丸のscore countが右側より有意に低下している例が全体の30%あり, 他の70%は左右差はなかった.score countと睾丸重量間には正の相関関係をみたが, 右側睾丸のscore countと精子濃度間には相関々係はなかった

The semen and testicular histology of 39 patients with varicocele on the left side, and who had high ligation of the internal spermatic vein at our Department between 1975 and 1981 was examined. The grade of varicocele was neither related to density nor motility of the sperm, nor to the score count of the left testis. In 40% of the patients, both density and motility of the sperm improved after the surgical treatment. In 80% of the patients, the left testis weighed less than the right testis. In most of the patients, the score count of both testes was lower than normal, and was found to decrease remarkably in testes weighing less than 10 g. In 30% of the patients, the score count of the left testis was lower than that of the right testis. A positive correlation was recognized between score count and testicular weight, and no correlation was found between the score count of the right testis and sperm density.
