We describe our experience with vasal aspiration of sperm in patients with azoospermia secondary to neurogenic anejaculation or obstruction of the vas deferens.
We performed 15 vasal sperm aspirations on 11 patients with neurogenic anejaculation or vasal obstruction.
Adequate sperm was obtained from all 15 aspirations with an average sperm count of 42 x 10[6] (range 0.5 to 252 x 10[6]) and an average motility of 73.4% (range 16 to 100%). Aspirations were performed for use with assisted reproductive techniques in 12 cases and for cryopreservation alone in 3. Following assisted reproductive techniques 6 of the 12 aspirations (50%) resulted in pregnancy.
Vasal aspiration of sperm should be considered when electroejaculation fails, is not available or is contraindicated. Although the overall sperm quality and pregnancy rate are higher with vasal aspiration and in vitro fertilization than electroejaculation and intrauterine insemination, vasal aspiration is a more technically demanding and costly approach to conception.
我们描述了对因神经源性不射精或输精管梗阻导致无精子症患者进行输精管精子抽吸的经验。
我们对11例神经源性不射精或输精管梗阻患者进行了15次输精管精子抽吸。
15次抽吸均获得了足够的精子，平均精子计数为42×10⁶（范围0.5至252×10⁶），平均活力为73.4%（范围16至100%）。12例抽吸用于辅助生殖技术，3例仅用于冷冻保存。在辅助生殖技术后，12次抽吸中有6次（50%）成功妊娠。
当电射精失败、无法进行或存在禁忌时，应考虑进行输精管精子抽吸。尽管输精管抽吸和体外受精的总体精子质量和妊娠率高于电射精和宫内人工授精，但输精管抽吸是一种技术要求更高且成本更高的受孕方法。
