This procedure was devised in an attempt to treat azoospermia caused by severe vas obstruction. An artificial spermatocele is prepared by resection of the vas slightly distal to the epididymal-deferential ansa and anastomosing onto its proximal stump a piece of Dardik's prosthesis sealed at the far end. During the partner's ovulatory period the spermatocele fluid is aspirated, mixed with fertile donor seminal plasma and used for artificial insemination. To date 8 subjects have had the operation: spermatocele fluids of 4 contained some highly motile spermatozoa with normal ability to penetrate cervical mucus for some months. Spermatocele implantation onto the vas apparently has the following advantages: the anatomic and functional integrity of the epididymis is maintained, the storage function of the epididymal-deferential ansa is preserved, and the risk of spermatocele collapse seems to be reduced by the high "vis a tergo" developed during ejaculation.
该手术方法是为治疗严重输精管阻塞所致无精子症而设计的。通过在附睾-输精管袢稍远侧切除输精管，并将一段远端封闭的达迪克假体吻合到其近端残端，制备人工精液囊肿。在配偶排卵期，抽吸精液囊肿液，与有生育能力的供体精浆混合，用于人工授精。到目前为止，已有8名受试者接受了该手术：4名受试者的精液囊肿液中含有一些活动力很强的精子，在几个月内具有正常穿透宫颈黏液的能力。将精液囊肿植入输精管显然具有以下优点：维持附睾的解剖和功能完整性，保留附睾-输精管袢的储存功能，射精时产生的高“推力”似乎降低了精液囊肿塌陷的风险。
