Vasectomy Reversal-Age of the female is important.

In addition to the skill of the surgeon, the character of the fluid at the time of the reversal, and years since the vasectomy…the age of the female is an important factor in achieving pregnancy.

What Affects Pregnancy, Patency Rates After Vasectomy Reversal?

Urology – October 30, 2015 – Vol. 33 – No. 4

The Silber grading scale appears to dictate pregnancy rates after vasectomy reversal with increasing female age being a negative predictive factor.

Article Reviewed: Impact on Pregnancy of Gross and Microscopic Vasal Fluid During Vasectomy Reversal. Ostrowski KA, Polackwich AS, et al: J Urol; 2015;194 (July): 156-159.

Background: The examination of the vasal fluid at the time of vasectomy reversal has implications for surgical decision making with effects on patency and pregnancy rates. The Silber grading system characterizes these findings and has been used to help surgeons with the decision to perform vasovasostomy (VV) or the more technically challenging vasoepididymostomy (VE).

Objective: To determine both intraoperative and patient factors that affect pregnancy rates after vasectomy reversal.

Design: Retrospective review of prospectively maintained database.

Methods: This paper reviewed the results of a single surgeon series that encompassed >30 years of vasectomy reversals. Vasal fluid was characterized as opalescent, creamy, pasty or clear and intraoperative light microscopy was used determined if sperm parts were present or motile. Univariate and multivariate analysis examined the data set for significant factors that affected pregnancy rates.

Results: 2947 vasectomy reversals were included in the analysis. Pregnancy status was only known for 31% of these cases. Bilateral VV was performed 83% of the time and most patients fell into a Silber 1 to 3 classification. No factors met statistical significance for increasing the pregnancy rate, although the presence of motile sperm was almost significant (P =0.075).

Negative predictive factors for pregnancy were identified on multivariate analysis with increasing female age and the findings of either no sperm (odds ratio [OR], 0.08) or sperm heads only (OR, 0.46) on microscopy decreasing pregnancy rates. Rarely were sperm parts identified when pasty fluid was encountered.

Conclusions: The findings from this paper echo the findings of the Vasovasostomy study group, with the Silber grading system essentially dictating pregnancy rates.

Reviewer’s Comments: The decision to perform VV or VE can be a difficult one and is based on many factors including findings from the vasal fluid, time since vasectomy, and surgeon skill level. Few papers have examined this decision-making algorithm since the landmark paper by the Vasovasostomy study group in 1991. While most microsurgeons prefer VV to VE due to increased patency and pregnancy rates, the need to perform a VE is generally encouraged when pasty fluid or no sperm parts are found in the vas at the time of reversal. These findings are interesting and are another important addition to the literature. Unfortunately, despite the authors’ efforts, relatively few predictive factors were found. Their findings do somewhat parallel those published by the Vasovasostomy study group, wherein the Silber grading system appears to correlate with pregnancy rates. The authors identified sperm heads only (Silber 4) or no sperm (Silber 5) as negative predictors with motile sperm (Silber 1) almost achieving statistical significance as a positive factor.(Reviewer–Charles Welliver, MD).

Tubal ligation vs. Vasectomy-which is more common?

1427215753am

The more invasive tubal ligation still outnumbers vasectomy among the options for permanent sterilization for couples. The rationale for this involves speculation, but male partner anxiety surrounding issues of sexual function have been proposed and are certainly evident when counseling males before vasectomy.

Vasectomy is not associated with decreased frequency of sexual intercourse.
Article Reviewed: Relationship Between Vasectomy and Sexual Frequency. Guo DP, Lamberts RW, Eisenberg ML: J Sex Med; 2015;12 (September): 1905-1910.
Background: Men often report the concern that having a vasectomy will impair their future sexual function.

Objective: To determine in an objective and quantifiable manner if vasectomy leads to a decrease in sexual frequency.

Design: The authors analyzed data from the National Survey of Family Growth (NSFG), which is a large survey of American households.

From Vasectomy.com

If one of the things that makes you uneasy about a vasectomy is the idea of a needle near that very sensitive area, fear not. One of the newer techniques allows physicians to apply anesthetic needle-free, with virtually no pain whatsoever.
