对5例输精管阻塞及重度生育力低下不育患者的附睾精子吸引术体外受精结果进行报告。 5例患者中,腹股沟疝术后输精管阻塞1例;不明原因无精子症2例;睾丸活检有少量分化正常的精子,输精管造影正常,输精管感染精子无力症1例,脊髓损伤不射精1例。腰椎麻醉,切开阴囊,显露睾丸附皋,在手术显微镜下切开附睾尾部被膜约5×5mm~2,除去被膜下脂肪组织,显露附睾管。用30gauge针头刺入附睾管吸取管内液,立即镜检。如无活动精子,沿切开部位向附睾头部移动,直至查到活动精子为止。精子取出后,经4～6小时培养,供体外受精。结果:取精成功3例,活动精子总数为116～345×10~4,卵子受精率52%。虽均未达到妊娠,但
Five cases of vas deferens obstruction and severe infertility patients with infertility epididymal sperm aspiration results reported in vitro fertilization. In 5 patients, vasectomy occured in one patient after inguinal hernia; in 2 patients with unexplained absence of spermatozoa; spermatozoa with poorly differentiated spermatozoa, normal vas deferens, vas deferens sperm infertility in 1 patient, and spinal cord injury without ejaculation in 1 patient. Lumbar anesthesia, incision scrotum, revealed testicular appendage, under the operating microscope incision of the epididymis tail membrane about 5 × 5mm ~ 2, remove the capsule under the fatty tissue, revealed the epididymal tube. Pierce the tube with 30gauge needles into the tube of the epididymal tube and examine immediately. If there is no movement of sperm, along the incision to the head of the epididymis until the activity sperm so far. Sperm removed after 4 to 6 hours for in vitro fertilization. Results: Three cases were successful in sperm injection. The total number of spermatozoa was 116-345 × 10 ~ 4, and the fertilization rate was 52%. Although did not reach pregnancy, however
