Microsurgical varicocelectomy (MVC) is the current gold standard for the treatment of varicocele. Studies have shown that MVC can bring certain clinical benefits to patients with varicocele and male infertility. In today’s era of assisted reproduction, MVC is clinical used usually to improve ART outcomes before treatment with assisted reproductive technology (ART). This article summarizes the efficacy evaluation and cost-effectiveness of MVC combined with ART. Although there is a lack of prospective evidence supporting MVC before ART, many large retrospective studies have shown that operating MVC before using ART may improve ART outcomes. However, large-scale and standardized clinical trials are still needed to further verify the effectiveness and feasibility of MVC before ART.
①供體授精:我們發現,在供體授精的效果方面,尚缺乏高質量證據.②胞漿內精子注射+體外授精:1篇系統評價發現,尚無足夠的證據說明胞漿內精子注射+體外授精與單獨使用體外授精何者效果更好.③宮腔內人工授精:兩篇系統評價發現,宮腔內人工授精較宮頸內授精或自然性交,能明顯增加每個周期的妊娠率.④體外授精與配子輸卵管內移植:1個RCT顯示,尚無足夠證據證明體外授精與配子輸卵管內移植何者效果更好.
