Higher Outcomes of Vasectomy Reversal in Men with the Same Female Partner as Before Vasectomy

PURPOSE We reviewed fertility outcomes of vasectomy reversal at a high surgical volume center in men with the same female partner as before vasectomy. MATERIALS AND METHODS We retrospectively studied a prospective database. All vasectomy reversals were performed by a single surgeon (EFF). Patients who underwent microsurgical vasectomy reversal and had the same female partner as before vasectomy were identified from 1978 to 2011. Pregnancy and live birth rates, procedure type (bilateral vasovasostomy, bilateral vasoepididymostomy, unilateral vasovasostomy or unilateral vasoepididymostomy), patency rate, time from reversal and spouse age were evaluated. RESULTS We reviewed the records of 3,135 consecutive microsurgical vasectomy reversals. Of these patients 524 (17%) who underwent vasectomy reversal had the same female partner as before vasectomy. Complete information was available on 258 patients (49%), who had a 94% vas patency rate. The clinical pregnancy rate was 83% by natural means compared to 60% in our general vasectomy reversal population (p <0.0001). On logistic regression analysis controlling for female partner and patient ages, years from vasectomy and vasectomy reversal with the same female partner the OR was 2 (p <0.007). Average time from vasectomy was 5.7 years. Average patient and female partner age at reversal was 38.9 and 33.2 years, respectively. CONCLUSIONS Outcomes of clinical pregnancy and live birth rates are higher in men who undergo microsurgical vasectomy reversal with the same female partner. These outcomes may be related to a shorter interval from vasectomy, previous fertility and couple motivation.

Impact on Pregnancy of Gross and Microscopic Vasal Fluid during Vasectomy Reversal.

PURPOSE We compared fertility outcomes with gross and microscopic fluid findings at vasectomy reversal at a high volume vasectomy reversal center. MATERIALS AND METHODS A retrospective study of a prospective database was performed. All vasectomy reversals were performed by a single surgeon (EFF) between 1978 and 2011. The clinical pregnancy rate was self-reported or determined via patient mailers. Patient and operative findings were determined through database review. We classified vasal fluid as opalescent, creamy, pasty or clear. Intraoperative light microscopy was used to determine if sperm or sperm parts were present and if they were motile. Multivariate analysis was performed evaluating patient age, partner age, years after vasectomy, type of surgery, and gross and microscopic fluid analysis. RESULTS A total of 2,947 microsurgical vasectomy reversals were reviewed after we excluded reversals performed for post-vasectomy pain. We determined the pregnancy status of 902 (31%) cases. On univariate analysis with respect to pregnancy the presence of motile sperm at vasovasostomy neared statistical significance (p=0.075) and there was no difference between bilateral vs unilateral motile sperm. Gross fluid appearance was not statistically significant but we found the order of pregnancy success to be opalescent, creamy, clear then pasty fluid. On multivariate analysis only female partner age and sperm heads only or no sperm seen on light microscopy had statistical significance (p <0.05). CONCLUSIONS The presence of motile sperm at vasectomy reversal approaches statistical significance on univariate analysis as a factor that affects clinical pregnancy rates. On multivariate analysis female partner age and microscopic findings of sperm heads only or no sperm are inversely related to pregnancy rates. These data will help counsel couples after vasectomy reversal and reinforce the importance of female partner age.

Relating economic conditions to vasectomy and vasectomy reversal frequencies: a multi-institutional study.

PURPOSE It was theorized that the use of permanent contraceptive methods may vary with economic conditions. We evaluated the relationship between vasectomy/vasectomy reversal frequencies at several large referral centers and national economic indicators during 2 recessions spanning 2001 to 2011. MATERIALS AND METHODS We performed an institutional review board approved, retrospective chart review to identify the number of vasectomies/vasectomy reversals per month at several large referral centers from January 2001 to July 2011. The rates of these procedures were pooled, correlated with national economic data and analyzed in a multivariate linear regression model. RESULTS A total of 4,599 vasectomies and 1,549 vasectomy reversals were performed at our institutions during the study period. The number of vasectomies per month positively correlated with the unemployment rate (r=0.556, p<0.001) and personal income per capita (r=0.276, p=0.002). The number of reversals per month negatively correlated with the unemployment rate (r=-0.399, p<0.001) and personal income per capita (r=-0.305, p<0.001). Neither vasectomy nor vasectomy reversal frequency significantly correlated with the inflation rate or the S&P 500®. Regression models confirmed that the unemployment rate explained more of the variance in vasectomy/vasectomy reversal frequencies than other indicators. CONCLUSIONS We noted a correlation between the number of vasectomies/vasectomy reversals performed at our institutions and national economic indicators. The strongest association was with the unemployment rate. This points to the importance of financial pressure on family planning decisions.

MP68-19 FACTORS AND PRACTICE PATTERNS THAT AFFECT THE DECISION FOR VASOEPIDIDYMOSTOMY

INTRODUCTION To determine the factors used to make the decision between vasovasostomy (VV) and vasoepididymostomy (VE) by leaders performing microsurgical vasectomy reversal using a questionnaire. MATERIALS AND METHODS An online questionnaire was sent to all members of the Society for the Study of Male Reproduction (SSMR), a male reproduction subspecialty society of the AUA, using the SurveyMonkey platform. RESULTS Sixty-seven surgeons responded to the questionnaire (27% of SSMR members). Of which 72% of members performed less than 50 vasectomy reversals per year. Also, 71% of members stated that less than 20% of their vasectomy reversals are vasoepididymostomies. When evaluating epididymal fluid at the time of reversal, 87% would perform a VE for pasty fluid, 66% with creamy fluid without sperm heads and 55% with no or scant fluid. With respect to banking sperm, 36% take sperm or testicular tissue at the time of VE while 37% sometimes take sperm mostly depending on the couples preference. The Berger end-to-side with intussusception VE technique is used by the majority of members (78%). The presence of intact sperm or sperm parts determined the location in the epididymis for anastomosis for 55% and 19% of members respectively. Postoperative semen testing after a VE is evaluated first between 6 weeks to 3 months for 64%. The procedure is considered a failure between 6 to 12 months for 34% and 12 to 18 months for another 48% if no sperm is seen on semen analysis. CONCLUSIONS Most members perform a VE with pasty fluid or creamy fluid without sperm heads. Three out of four members are using the Berger end-to-side intussusception technique to perform their VE. More studies are needed to determine the optimal circumstances to perform a VE as there is significant variation in responses even among members of the SSMR.
