Zusammenfassung:Vasectomy is a widely used method of contraception. However, some men may have the desire to become biological fathers again after a period. To explore the effect of time since vasectomy and different male comorbidities on live birth rates from intracytoplasmic sperm injection cycles using donated oocytes by using testicular spermatozoa obtained by testicular sperm extraction. This was a retrospective study of 123 couples who underwent a testicular sperm extraction‒intracytoplasmic sperm injection cycle after vasectomy using donated oocytes. Subjects were divided into groups according to time since vasectomy and the male risk factor evaluated. The main outcomes measured were live birth rate per embryo transfer, per oocyte donation cycle, and per couple. We assessed the cumulative live birth rate according to the time since vasectomy and considered male comorbidities: body mass index, hypertension, diabetes mellitus, dyslipidemia, and smoking. The overall live birth rate per couple was 59.3% (50.6-68.0). Considering the number of embryo transfer and oocyte donation cycle, the live birth rates were 34.1% (27.8-40.4) and 44.5% (36.9-52.1), respectively. The live birth rate according to time since vasectomy was not statistically different between groups. Consequently, the cumulative live birth rate was similar between the different interval times when considering one to eight embryo transfers (p = 0.74). No statistical differences in live birth rate and cumulative live birth rate were found between groups clustered according to male body mass index, smoking, hypertension, and dyslipidemia. However, diabetic male patients had a significantly lower rate of live birth rate per couple (22.2% [4.94-49.4]) than non-diabetic patients did (62.7% [53.7-71.8]) (p = 0.03), but not in their cumulative live birth rate. The time since vasectomy seems to have no detrimental effects on the live birth rate and cumulative live birth rate in testicular sperm extraction‒intracytoplasmic sperm injection cycles with donated oocytes. Male diabetes negatively affects the overall live birth rate per couple, but not the cumulative live birth rate. These results could be useful for multidisciplinary patient-tailored counseling, regarding the chance of having a pregnancy and facilitating the decision-making process of the fertility specialists.
