National Characteristics of Surgeons Performing Vasectomy: Increasing Specialization and a Persistent Gender Gap. Urology 2020; 143:130-136. [PMID: 32325136 DOI: 10.1016/j.urology.2020.04.016] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/16/2019] [Revised: 03/25/2020] [Accepted: 04/05/2020] [Indexed: 11/25/2022]
Abstract
OBJECTIVE To describe trends in the characteristics of urologic surgeons performing vasectomy over time. METHODS We performed a retrospective, cross-sectional study examining surgeon characteristics for case logs from the American Board of Urology between 2004 and 2013. We used generalized estimating equations with a log link and negative binomial distribution to examine demographic differences (gender, rural location, and surgeon volume) in the number of vasectomies surgeons performed over time. RESULTS Between 2004 and 2013, 5316 urologists had case logs collected within the 7-month certification window. The majority of these surgeons self-identified as general urologists (82.8%), and a small proportion identified as andrology and infertility specialists (1.7%). Across all years, the median number of vasectomies performed per certifying surgeon during the study period was 14 (interquartile range 6-26). The majority of vasectomies were performed by high-volume surgeons (≥ 26 vasectomies) ranging from 49.2% to 66.9% annually, whereas the proportion performed by low-volume (≤ 5 vasectomies) surgeons ranged from 3.3% to 6.6% annually. Male surgeons performed vasectomies 2.20 times more frequently than female surgeons (95% confidence interval 1.93-2.49; P <.0001) across the study period with no evidence to suggest this gap changed over time (gender-year interaction 1.01 [95% confidence interval: 0.97-1.06; p = .576]). CONCLUSION While the majority of urologists performing vasectomy identify as general urologists, there appears to be a focus on vasectomy practice among a small number of high-volume surgeons. Furthermore, while the number of female surgeons performing vasectomies increased, a gender gap persists in the proportion of vasectomies performed by females.

Abstract
According to data from the National Study of Family Growth, vasectomy is utilized by 6–13% of American couples for their form of contraception. Physician surveys have shown that over 500,000 men undergo vasectomies per year, and more than 75% of vasectomies are performed by urologists. This chapter provides a brief history of vasectomy, as well as recommendations for preoperative counseling, an overview of the modified no-scalpel vasectomy technique, and a brief description of the complications of vasectomy.

Abstract
PURPOSE While hospital discharge and ambulatory surgery registries provide accurate estimates of female sterilization procedures, current estimates of male sterilization rates are lacking since these procedures are done in many settings. Population based data are used to estimate annual sterilization numbers. MATERIALS AND METHODS We analyzed data on 4,928 men and 7,643 women from the 2002 National Survey of Family Growth. We determined the year of vasectomy in men and the year of tubal ligation in women who reported a history of surgical sterilization. After accounting for the complex survey design of the National Survey of Family Growth we calculated the estimated number of individuals who underwent surgical sterilization in the United States. RESULTS A total of 141 men reported vasectomy, representing an overall 6% prevalence in National Survey of Family Growth survey population, while 1,173 women (16%) reported tubal ligation. Using National Survey of Family Growth data an estimated 175,000 to 354,000 vasectomies were done yearly from 1998 to 2002. In the same period the National Survey of Family Growth estimated that 546,000 to 789,000 tubal ligations were done annually in the United States. This compares closely to the 596,000 to 687,000 tubal ligations calculated using ambulatory surgery and hospital discharge data from a similar period. CONCLUSIONS The estimated annual number of tubal ligations from the National Survey of Family Growth is in line with the current literature using hospital discharge and ambulatory surgery registries, suggesting the accuracy of the method of estimating surgical sterilization numbers. This suggests that the National Survey of Family Growth may be used to provide an estimate of vasectomy use in the United States.

Abstract
OBJECTIVES To explore whether health care, socioeconomic, or personal characteristics account for disparities observed in the utilization of vasectomy. More than 500,000 vasectomies are performed annually in the United States. The safety and efficacy of vasectomy make it a good family planning option, yet the factors related to use of male surgical sterilization are not well understood. In this analysis, we examined differences in vasectomy rates according to factors such as race and socioeconomic status. METHODS We analyzed data from the male sample of the 2002 National Survey of Family Growth to examine the use of vasectomy among the sample of men aged 30-45 (n = 2161). Demographic, socioeconomic, and reproductive characteristics were analyzed to assess associations with vasectomy. RESULTS About 11.4% of men aged 30-45 years reported having a vasectomy, representing approximately 3.6 million American men. Although 14.1% of white men had a vasectomy, only 3.7% of black and 4.5% of Hispanic men reported undergoing vasectomy. On multivariate analysis, a significant difference in the odds of vasectomy by race/ethnicity remained, with black (odds ratio = 0.20, 0.09-0.45) and Hispanic men (odds ratio = 0.41, 0.18-0.95) having a significantly lower rate of vasectomy independent of demographic, partner, and socioeconomic factors. Having ever been married, fathering 2 or more children, older age, and higher income were the factors associated with vasectomy. CONCLUSIONS After accounting for reproductive history, partner, and demographic characteristics, black and Hispanic men were less likely to rely on vasectomy for contraception. Further research is needed to identify the reasons for these race/ethnic differences and to identify factors that impede minority men's reliance on this means of fertility control.

Abstract
Vasectomy is safer, simpler, less expensive, and equally as effective as female sterilization--yet it remains one of the least known and least used methods of contraception. Worldwide, an estimated 33 million of married women ages 15 to 49 (less than 3%) rely on their partner's vasectomy for contraception.

Abstract
Despite significant advances in contraceptive options for women over the last 50 yr, world population continues to grow rapidly. Scientists and activists alike point to the devastating environmental impacts that population pressures have caused, including global warming from the developed world and hunger and disease in less developed areas. Moreover, almost half of all pregnancies are still unwanted or unplanned. Clearly, there is a need for expanded, reversible, contraceptive options. Multicultural surveys demonstrate the willingness of men to participate in contraception and their female partners to trust them to do so. Notwithstanding their paucity of options, male methods including vasectomy and condoms account for almost one third of contraceptive use in the United States and other countries. Recent international clinical research efforts have demonstrated high efficacy rates (90-95%) for hormonally based male contraceptives. Current barriers to expanded use include limited delivery methods and perceived regulatory obstacles, which stymie introduction to the marketplace. However, advances in oral and injectable androgen delivery are cause for optimism that these hurdles may be overcome. Nonhormonal methods, such as compounds that target sperm motility, are attractive in their theoretical promise of specificity for the reproductive tract. Gene and protein array technologies continue to identify potential targets for this approach. Such nonhormonal agents will likely reach clinical trials in the near future. Great strides have been made in understanding male reproductive physiology; the combined efforts of scientists, clinicians, industry and governmental funding agencies could make an effective, reversible, male contraceptive an option for family planning over the next decade.

Abstract
Medical barriers to contraception can prevent women from obtaining, initiating, and continuing their contraceptive method of choice. The barriers include lack of appropriate counseling, delaying initiation for menses or laboratory tests, inappropriate contraindications or mandated warnings, untrained clinicians, and financial or regulatory barriers preventing access by low-income, undocumented, or adolescent women. These barriers may partially explain why almost half of pregnancies in the United States are unintended and occur predominantly in the small proportion of sexually active women not using contraception.

Abstract
PURPOSE We estimated the number of vasectomies performed in the United States in 2002 and gathered information on the vasectomy procedures and protocols used. It follows similar studies done in 1991 and 1995. MATERIALS AND METHODS A retrospective mail survey with telephone followup was performed in 2,300 urologists, family physicians and general surgeons randomly sampled from the American Medical Association Physician Masterfile. RESULTS The response rate was 73.8%. An estimated 526,501 vasectomies were performed in 2002 for a rate of 10.2/1,000 men 25 to 49 years old. Overall 37.8% of physicians reported currently using no scalpel vasectomy and almost half of the vasectomies performed in 2002 were no scalpel vasectomies. Methods of vas occlusion varied in and among specialties with a combination of ligation and cautery being most common (41.0% of cases). Of the physicians 45.6% reported routinely performing fascial interposition, 94.4% reported removing a vas segment, 23.3% reported routinely folding back 1 or 2 ends of the vas and 7.5% reported using open-ended vasectomy. Followup protocols varied widely. Of respondents 53.5% reported charging $401 to $600 for vasectomy in 2002. CONCLUSIONS Although the estimated number of vasectomies performed in the United States during 2002 represents an increase from 1991 and 1995, incidence rates remained unchanged at approximately 10/1,000 men 25 to 49 years old. The percent of vasectomies performed using no scalpel vasectomy as well as the number of physicians who reported that they use no scalpel vasectomy increased substantially since 1995. Wide variation in surgical techniques and followup protocols were found.

Abstract
OBJECTIVES To evaluate the association of vasectomy with prostate cancer. METHODS Participants were male members of the CLUE II cohort followed since 1989. On a questionnaire mailed in 1996, the men were asked if they had had a vasectomy and their age at vasectomy. Between 1996 and April 2004, 78 prostate cancer cases were confirmed among the 3373 men who were at least 35 years old at baseline and who completed the questions about vasectomy. Cox proportional hazards regression was used to estimate age-adjusted hazard ratios (HR) of prostate cancer. RESULTS The HR for prostate cancer for men who had had a vasectomy was 2.03 (95% CI: 1.24-3.32). Risk of low-grade disease (HR=2.87; 95% CI 1.49-5.54), but not high-grade disease (HR=0.99; 95% CI 0.36-2.76), was higher in men who had had a vasectomy. No statistically significant associations were observed for low- or high-stage disease. The association for vasectomy was more pronounced in men who were 40 years at the time of vasectomy (HR=2.63; 95% CI 1.40-4.94) than in men who were younger at vasectomy. CONCLUSIONS The results from this prospective study suggest a positive association between vasectomy and prostate cancer, especially low-grade disease.

Abstract
OBJECTIVES The aims of this paper are: 1. To study the demand and reasons why of the vasectomy in area 12 of Valencian Community. 2. To analyse the adverse effects of our series and the predictable risk factors. 3. To review the adverse effects in the national series. 4. To review the adverse effects referred to in international publications. PATIENTS AND METHODS A retrospective study was made of 300 patients who had submitted themselves to a vasectomy between january 1992 and december 2000. All the clinical dossiers were reviewed according to 10 pre-established variables. age, number of offspring, reasons why, pre-vasectomy anticontraceptives; date of operation, type of anaesthesia used, pathologic anatomy, semen analysis after vasectomy, adverse effects and their possible causes (risk factors). The basic statistic study was done using a data base of Microsoft Access and the interpretations of the different variables using a table of Excel. RESULTS The demand for contraceptive attention (vasectomy) is the 8th cause for external urological consulting and the 4th for urological local ambulatory surgery of our area. 300 operations were done during that period. The average age of the patients was 37.5 years old (ranging from 25 to 51). The number of offspring ranged from 1 to 7, with a promedia of 2.41 children/patient. The reasons why were: voluntary family planning (86%), medical illnesses of the female which contraindicated gestation (9%), genetic reasons (4.33%) and social-sanitary problems (0.66%). Contraceptive methods used by 71.63% are known: The widest-used method being IUD (49.74%) and the preservative (25.88%). 30 patients (10%) had adverse effects, 29 patients having light adverse effects. The most frequent were: 12 orchiepididymitis (4%), 5 spermatic granulomas (1.66%), 3 chronic scrotal pain (1%), 2 scrotal haematoma (0.66%) and 2 bleeding (0.66%). There was one serious complications and of all the cases mentioned above only one needed hospitalization (impetigo-sepsis) and another needed surgery due to a spermatic granuloma. There were no pregnancies or post-vasectomy court cases. 81% of the patients had been declared azoospermic within 45 to 60 days after the vasectomy in one or two consecutive semen analysis. CONCLUSIONS The vasectomy is a safe and simple way for male sterilization. It's the most widely done urologic operation in Spain. The technique isn't extent of adverse effects (0 to 18%) and its seriousness varies from a simple ecchymosis to Fournier's gangrene, endocarditis or sepsis. A doctor would be considered negligent if he/she didn't inform the patient about the remote possibility of a spontaneous recanalisation of the vas deferens leading to renewed fertility (failure of the vasectomy). It is imperative to give post-vasectomy information where the patient must continue using his habitual anticonceptive method until the azoospermia shown in 2 semen analysis confirm the sterility of the patient so that the urologist has no legal problem.

Abstract
We surveyed 2000 US urologists using mailed questionnaires. The aim of this survey was to estimate the incidence of pregnancy after vasectomy and to gather information on the surgical methods used. Of 586 responding urologists, 538 reported performing vasectomies, and they reported a total of 177 pregnancies during the preceding 5 years. Ninety pregnancies (51%) were attributed to unprotected intercourse during the immediate post-vasectomy period. The remaining pregnancies were attributed to recanalization or other less common causes of method failure. Based on the number of vasectomies performed by these surgeons, about 1 pregnancy was reported per 1000 vasectomies. This is probably an underestimate of the true rate. The risk of pregnancy was lower following vasectomies by surgeons who performed more than 50 procedures per year.

Abstract
Vasectomy is regarded as the safest method now available for male fertility control. Almost 100 million men worldwide have relied on vasectomy for family planning. This review discusses all currently relevant operative techniques, including no-scalpel vasectomy, complications, possible long-term effects on the testis and epididymis, and diseases for which associations with vasectomy have been suggested, such as arteriosclerosis, autoimmune diseases and cancer of the prostate and testis. Other topics of discussion include the timing of post-operative semen analysis, patient noncompliance concerning post-operative controls, persistent cryptozoospermia and transient reappearance of spermatozoa after vasectomy, vasectomy failure and legal aspects.

Abstract
OBJECTIVE To determine the long-term safety of nonsurgical sterilization with quinacrine. DESIGN Observational cohort study. SETTING Rural provinces in northern Vietnam. PATIENT(S) Two thousand eight hundred forty women who had had quinacrine insertions and an age-matched comparison group of 1,658 women who had an intrauterine device (IUD) insertion between 1989 and 1993. METHOD(S) Interviews in 1994, 1995, and 1996 and review of available medical records. This is a planned interim analysis. MAIN OUTCOME MEASURE(S) Ectopic pregnancies and the occurrence of other adverse health events. RESULT(S) Over 90% of women were interviewed at least once. Despite matching on age, the groups differed on baseline parity. The ectopic pregnancy rates were similar after either one or two insertions and were similar to the rate of ectopic pregnancies after surgical sterilization in the United States. The quinacrine group reported more gynecologic health problems than the IUD group. However, after correcting for information bias, there was no dose-response effect between the one- and two-insertion quinacrine groups, suggesting the possibility of recall bias or differing baseline health status. CONCLUSION(S) Ectopic pregnancies do not appear to be increased compared with U.S. surgical sterilization rates. The data on other adverse events are more difficult to interpret.
