초록

목 적: 보조생식술에서의 정자처리법으로서 인간 난포액을 이용한 swim-down 방법의 유용성을 확인해 보고자 하였다. 연구방법: 분당서울대학교병원 산부인과에서 불임평가 목적으로 정액검사를 시행할 때 정자무력증 (asthenozoospermia, sperm motility < 50%)을 보이는 12명의 남성을 대상으로 하였다. 이들에서 검사 후 남은 정액을 100% 인간 난포액을 이용한 swim-down법과 SpermGrad를 이용한 밀도차 분리법을 적용하여 각각 처리하고 컴퓨터 정액분석기를 이용하여 정액검사를 시행하였다. 결 과: 두 군 모두에서 운동성과 빠른 운동성 정자의 비율, VCL (curvilinear velocity), ALH (amplitude of lateral head displacement)치 및 과활동성 정자의 비율이 통계적으로 유의하게 상승하였고 LIN (mean linearity)치는 유의하게 감소하였다. 100% 인간 난포액을 이용한 swim-down법에서 정자의 운동성이 SpermGrad를 이용한 밀도차분리법에 비하여 유의하게 높게 나타났으며 ($81.2{\pm}4.7$ vs. $67.6{\pm}2.3$, p=0.02), 다른 변수들은 두 군에서 차이를 보이지 않았다. 결 론: 100% 인간 난포액을 이용한 swim-down법은 정자무력증을 보이는 경우 유용한 정자 처리법으로 사료된다.

Objective: We tested the usefulness of swim-down technique using human follicular fluid (hFF) in sperm preparation. Methods: Semen samples were obtained from twelve male partners showing asthenozoospermia (sperm motility < 50%) at the time of routine andrologic evaluation in Seoul National University Bundang Hospital. After dividing into two aliquots, each samples were processed either by swim-down using 100% hFF or density gradient using SpermGrad. Sperm quality was assessed by computer-assisted semen analyzer (CASA). Results: Motility, Rapid motility, VCL (curvilinear velocity), ALH (amplitude of lateral head displacement), and hyperactivated sperms were significantly increased, and LIN (mean linearity) was decreased significantly after sperm preparation in both groups. Motility was significantly higher after swim-down using 100% hFF when compared with density gradient using SpermGrad ($81.2{\pm}4.7$ vs. $67.6{\pm}2.3$, p=0.02) The other parameters assessed by CASA were not different between the two methods. Conclusion: Swim-down method with 100% hFF may be a useful method in preparation of sperm from asthenozoospermia.
