Literature regarding the influence of maternal age on pregnancy rates with male partners who have undergone vasectomy reversal is sparse. With the tendency towards delayed childbirth, the increased use of vasectomy as means of family planning, and advances in reproductive techniques, this issue is very important for patient counseling. The aim of this study is to determine the importance of maternal age on pregnancy rates following vasectomy reversal.
A retrospective analysis was performed on 212 patients who underwent vasectomy reversal by a single surgeon (W.H.W.). Patient characteristics of the male and the female partner were evaluated using the Fisher exact test and predictors of pregnancy were identified using multivariable logistic regression analyses.
The mean age of the male patients was 40.4 years and the mean age of their female partners was 31.3 years. The postoperative vas patency rate was 93.4%, which resulted in a pregnancy rate of 72.2%. In univariate and multivariable analysis, the age of the female partner (p = 0.014 univariate and p = 0.010 multivariable) and Silber score (p = 0.028 univariate and p = 0.024 multivariable) were predictive of pregnancy following vasectomy reversal with age of the female partner >40 years being associated with lower pregnancy rates compared to those <or=29 and 30-39 years.
Maternal age of >or=40 years is an independent predictor of a lower rate of pregnancy following vasectomy reversal but still compared favorably to published pregnancy rates following intracytoplasmatic sperm injection in patients aged 40 years and older. Therefore, vasectomy reversal should be the treatment of choice for patients with advanced maternal age desiring reinstated fertility following vasectomy.
关于母亲年龄对输精管复通男性伴侣受孕率影响的文献稀少。随着生育推迟的趋势、输精管切除术作为计划生育手段的使用增加以及生殖技术的进步,这个问题对于患者咨询非常重要。本研究的目的是确定母亲年龄对输精管复通后受孕率的重要性。
对由单一外科医生(W.H.W.)进行输精管复通的212例患者进行回顾性分析。使用Fisher精确检验评估男性和女性伴侣的患者特征,并使用多变量逻辑回归分析确定受孕的预测因素。
男性患者的平均年龄为40.4岁,其女性伴侣的平均年龄为31.3岁。术后输精管通畅率为93.4%,受孕率为72.2%。在单变量和多变量分析中,女性伴侣的年龄(单变量p = 0.014,多变量p = 0.010)和Silber评分(单变量p = 0.028,多变量p = 0.024)可预测输精管复通后的受孕情况,与年龄≤29岁和30 - 39岁的女性相比,年龄>40岁的女性伴侣受孕率较低。
母亲年龄≥40岁是输精管复通后受孕率较低的独立预测因素,但与40岁及以上患者胞浆内单精子注射后的已发表受孕率相比仍具有优势。因此,对于输精管切除术后希望恢复生育能力的高龄母亲患者,输精管复通应是首选治疗方法。
