Abstract

We assessed the contribution of microsurgical seminal reconstruction to achieving natural conception in conjunction with advanced assisted reproductive technologies. Ninety obstructive azoospermic subjects who underwent microsurgical seminal reconstruction were evaluated. Vasovasostomy (VV) was undertaken in 45 subjects whereas vasoepididymostomy (VE) in 45, respectively. VV was performed by employing a two microlayer anastomotic technique, whilst VE was undertaken using double needle longitudinal vaspepididymostomy (LIVE). Patency was achieved in 41 VV (91.1%), and 25 VE (55.6%) cases. In cases where patency was achieved, pregnancy and healthy delivery were recorded following natural intercourse in 7/41 (17.0%) VV, and in 7/25 (28.0%) VE cases. Where patency was not achieved, the use of cryopreserved sperm for intracytoplasmic sperm injection (ICSI), resulted in a healthy delivery in 4/4 (100%) VV and 14/21 (66.6%) in VE subjects. Although natural pregnancy was achieved only in a limited number of subjects treated (14/90; 15.6%), sperm harvested during surgery and cryopreserved for future ICSI use proved valuable, doubling the overall delivery rate (32/90; 36.6%). Surgical intervention is considered to be a useful technique in order to allow the possibility of a natural conception and by harvesting sperm at the same time contributes to the cost-effectiveness.

摘要

我们评估了显微外科精液重建术结合先进的辅助生殖技术对实现自然受孕的贡献。90 名梗阻性无精子症患者接受了显微外科精液重建术。45 例患者行输精管吻合术(VV),45 例患者行附睾吻合术(VE)。VV 采用双微层吻合技术,VE 采用双针纵向附睾输精管吻合术(LIVE)。41 例 VV(91.1%)和 25 例 VE(55.6%)患者吻合成功。在吻合成功的病例中,7/41(17.0%)例 VV 和 7/25(28.0%)例 VE 在自然性交后记录到妊娠和健康分娩。在吻合未成功的病例中,使用冷冻保存的精子进行胞浆内单精子注射(ICSI),在 4/4(100%)例 VV 和 14/21(66.6%)例 VE 患者中获得了健康分娩。尽管只有少数接受治疗的患者(14/90;15.6%)实现了自然妊娠,但术中采集并冷冻保存以备将来 ICSI 使用的精子证明是有价值的,使总分娩率提高了一倍(32/90;36.6%)。手术干预被认为是一种有用的技术,可以实现自然受孕的可能性,同时通过采集精子来提高成本效益。
