To evaluate 2 methods of processing testicular tissue for the retrieval of viable sperm from men with nonobstructive azoospermia.
Fresh testicular tissue was obtained from nonobstructive azoospermia patients using a biopsy needle. The specimens were divided into 2 fractions. All specimens were minced and immersed in human tubal fluid (HTF). The first fraction was filtered through a nylon filter and incubated for 3 hours. The supernatant was centrifuged, resuspended in HTF and analyzed. The second fraction was immediately vortexed for 5 minutes and filtered through a nylon filter. The supernatant was centrifuged, resuspended in HTF and analyzed.
Spermatozoa were obtained in 13 of 24 cases (54.2%) using the vortex method and in 5 of 24 cases (20.8%) with the nylon filter method.
The vortex mixing method may be a better option than the conventional method for processing testicular tissue for sperm collection.
评估两种处理睾丸组织的方法,以从非梗阻性无精子症男性中获取活精子。
使用活检针从非梗阻性无精子症患者获取新鲜睾丸组织。标本分为两部分。所有标本均切碎并浸入人输卵管液(HTF)中。第一部分通过尼龙滤网过滤并孵育3小时。将上清液离心,重悬于HTF中并进行分析。第二部分立即涡旋5分钟并通过尼龙滤网过滤。将上清液离心,重悬于HTF中并进行分析。
使用涡旋法在24例中有13例(54.2%)获得精子,使用尼龙滤网法在24例中有5例(20.8%)获得精子。
对于处理睾丸组织以收集精子,涡旋混合法可能是比传统方法更好的选择。
