AI Article Synopsis
- The study aimed to assess the probability of sterilization reversal and subsequent sterilization or pregnancy in men and women.
- Researchers analyzed payment data from Quebec’s health insurance for individuals who underwent sterilization from 1980 to 1999, using survival analysis methods to evaluate various outcomes.
- Findings revealed that both men and women experienced notable rates of pregnancy and reversal following sterilization, particularly among younger individuals, highlighting the need for improved contraceptive counseling.
Article Abstract
Objective: 1). To determine the likelihood of sterilization reversal and of subsequent sterilization after sterilization reversal among men and women and 2). to examine the likelihood of pregnancy after sterilization (contraceptive failure) and of pregnancy after sterilization reversal.
Methods: Payment data from the Quebec provincial health insurance system were obtained for each person undergoing vasectomy or female sterilization from January 1, 1980 to December 31, 1999 and linked through a unique identifying number for each person. Using standard techniques of survival analysis, we computed the cumulative probability of experiencing each of six events.
Results: Among women, 0.9% (of 311960) experienced a pregnancy after sterilization, 1.8% (of 321929) obtained a reversal after sterilization, 61% (of 4369) achieved a pregnancy after sterilization reversal and 48% achieved a delivery; 23% (of 4677) obtained a subsequent sterilization after reversal. Among men, 2.4% (of 310827) obtained a reversal after vasectomy and 18% (of 6694) obtained a subsequent vasectomy after reversal. All of these risks were much higher among those in the youngest age groups.
Conclusion: Sterilization reversal and pregnancy after sterilization are not rare. Relatively high rates of reversal among the youngest age groups suggest a need for better counseling about alternative contraceptive strategies.

Background: Vasectomy reversal (VR) is the only technique that allows men previously submitted to a vasectomy to conceive by natural pregnancy. We report our experience with microsurgical VR and identify predictive factors of natural pregnancy.
Methods: We retrospectively reviewed all patients submitted to VR by a single surgeon from 2008 to 2021 at our single center.

The vasectomy is a safe and effective method of contraception for men. Up to 6% of men who underwent vasectomy have a renewed child wish. Microsurgical vasectomy reversal (VR) in men, microsurgical epididymal sperm aspiration (MESA), or testicular sperm extraction (TESE) in men plus assisted reproductive technology (ART) in the female partner as well as the combination of VR and MESA/TESE plus ART represent established therapeutic strategies.

Article Synopsis
- Tubal sterilization is the leading contraceptive method in the U.S., and this study investigates the rates of pregnancy following the procedure using data from the National Survey of Family Growth over various years.
- Results indicate that 2.9 to 5.2% of participants reported pregnancies after tubal sterilization, with lower rates associated with postpartum procedures compared to interval procedures, although this was not consistent in all analyses.
- The study found that older age at the time of sterilization decreased the likelihood of pregnancy, while factors such as race/ethnicity, education, and Medicaid funding did not have consistent impacts on post-sterilization pregnancy rates.
Factors affecting patency time and semen quality in a single-armed microsurgical vasoepididymostomy.

Although microsurgical vasoepididymostomy (MVE) is an effective treatment for epididymal obstructive azoospermia, some patients may experience delayed patency or suboptimal semen parameters after patency. However, research into patency time, semen quality postpatency, and associated influencing factors remains limited. This study aimed to address these issues by evaluating 181 patients who underwent at least one-sided MVE employing asingle-armed longitudinal intussusception vasoepididymostomy technique, with a follow-up period of over 12 months for 150 patients.

Introduction: Vasectomy is a relatively common procedure performed for the purposes of sterilization; however, up to 6% of men that undergo vasectomy wish for its reversal at some point. Few studies have examined the motivation behind vasectomy reversal (VR), especially within special populations, such as the U.S.
