男性不妊症における精液粘稠度について

Abstract

Determination of seminal viscosity in male infertility wa s performed by means of Hess' viscosimeter. Its relation to seminal volume, concentration and motility of spermatozoa and duration of abstinence were also observed. The results are summarized as follows : 1) Seminal viscosities of available 65 cases ranged between 2.8 and 15.2 with a n average of 6.95. 2) Conc e rning the relation to volume of ejaculate, the viscosity showed lower values in volume of under 1.9cc and over 6.0cc groups. 3) In the cases of azoospermia and h i g h grade oligozoospermia, the viscosity of semen varied in wide ranges and showed relatively high values than normozoospermic semen, of which average value was 4.68. 4) No significant relatio n ship was deteeted between the viscosity and motility rate of spermatozoa. However, a decrease of motility rate was observed in few instances with exceptionally high viscosity. 5) No notice a ble relationship was detected between the viscosity and duration of abstinence.
