Vasectomy is a popular choice of contraception worldwide. In the UK, vasectomy reversal is not usually licensed under the NHS with reports on outcomes being limited. Microsurgical reversal is a technique commonly performed under the operating microscope. Loupe magnification, however, is emerging as a safe and reliable technique to perform microsurgery.
Loupe-assisted microsurgical vasovasotomies were performed on 14 men in a 3-year period. Indications for the procedure were for fertility only. Semen analysis variables were measured against European Association of Urologists (EAU) guidelines at six weeks. Patients were followed-up at clinic in three months. Data were collated using operation notes and cytology results, and analysed using descriptive statistics. Pearson's correlation coefficient was used to compare years after vasectomy, and age to sperm count.
The average sperm count in our group was 41.3 million per millilitre (median 29.95, range 2.7-107.8) at 6 weeks. Seventy-five per cent were found to have positive sperm motility, and all had acceptable sperm morphology at follow-up. A very low to weak correlation between time after vasectomy and age, with sperm count.
We have demonstrated that fertility and post-operative outcomes using a loupe-assisted microsurgical vasovasotomy approach are favourable as per EAU guidelines.
输精管结扎术是全球范围内一种流行的避孕选择。在英国，输精管复通术通常不在国民保健制度（NHS）的许可范围内，因此报告的结果有限。显微外科复通术是一种在手术显微镜下常见的技术。然而，使用放大镜进行显微手术正逐渐成为一种安全可靠的技术。
在 3 年期间，对 14 名男性进行了放大镜辅助显微输精管吻合术。该手术的适应证仅为生育。精液分析变量根据欧洲泌尿外科学会（EAU）指南在 6 周时进行测量。患者在 3 个月时在诊所进行随访。使用手术记录和细胞学结果收集数据，并使用描述性统计进行分析。使用皮尔逊相关系数比较输精管结扎术后的年数和年龄与精子计数之间的关系。
我们组的平均精子计数为每毫升 4130 万（中位数 29.95，范围 2.7-107.8），在 6 周时。75%的患者发现精子活力呈阳性，且所有患者在随访时精子形态均可接受。输精管结扎术后时间与精子计数之间的相关性非常低或较弱，与年龄之间的相关性也很弱。
我们已经证明，使用放大镜辅助显微输精管吻合术的方法，根据 EAU 指南，生育能力和术后结果是有利的。
