BACKGROUND PVPS is different from acute post procedure pain. Acute post procedure pain typically resolves 2–4 weeks postoperatively whereas PVPS continues to persist or may occur months to years after the vasectomy. PVPS can be an extremely frustrating problem to treat for both the patient and the clinician, as there remains no widely accepted protocol for evaluation and treatment of the proble...

OBJECTIVE  To determine the association between vasectomy and prostate cancer, adjusting for measures of health seeking behaviour. DESIGN  Population based matched cohort study. SETTING  Multiple validated healthcare databases in Ontario, Canada, 1994-2012. PARTICIPANTS  326 607 men aged 20 to 65 who had undergone vasectomy were identified through physician billing codes and matched 1:1 o...

The present study was undertaken to clarify changes in secretions of FSH, LH, inhibin and testosterone, and sperm motility after bilateral vasectomy in adult male rats. Bilateral vasectomy was created surgically (treated group) and intact rats were used as control (control group). On days 3, 5, 7, 14, 30, 60, and 90 after surgery, plasma concentrations of FSH, LH, inhibin, and testosterone were...

Dear Editor, Researchers reported an association between vasectomy and primary progressive aphasia (PPA—a rare variety of frontotemporal dementia) in a 2006 manuscript in Cognitive Behavioral Neurology detailing a case–control study that compared 47 men with the disease to 57 controls. The rate of vasectomy in PPA patients was 40% (19/ 47) vs. 16% (9/57) in normal controls. This difference met ...

OBJECTIVE To evaluate the expression of the apoptotic genes survivin, Bax and Bcl-2 in vasectomized rabbits and to determine their relation with vasectomy-induced spermatogenic impairment and germ cell apoptosis. MATERIALS AND METHODS Twelve adult rabbits (6-12 months old) were divided into three groups: sham control, unilateral vasectomy or bilateral vasectomy. Six months after vasectomy, te...

PURPOSE To determine the prevalence of unilateral absence of vas deferens (UAVD) in men with both testes seeking vasectomy. MATERIALS AND METHODS Computerized charts of 23.013 patients encountered between January 1994 and December 2013 in one university hospital and two community clinics of Quebec City, Canada, were searched. Pre-vasectomy consultation, operative reports and semen analysis re...

Objective—The effects of vasectomy on testes and related structures are disputable. The aim of this study was to determine whether the reproductive organs of rabbits were influenced after 12 months vasectomy. Study design—Bilateral vasectomy was performed on 10 male adult New Zealand Big Eared White Rabbits (another 10 rabbits set as sham operated group) and tissue samples were examined by ligh...

The potential influence of vasectomy being a risk factor for the development of prostate cancer is not a new concept, with more than 30 publications addressing the topic. Given the global frequency of vasectomy and the prevalence of prostate cancer, this subject justifiably deserves scrutiny. Several articles have claimed that vasectomy puts men at risk for future development of prostate cancer...

Vasectomy is a highly effective and safe contraceptive method for couples who want to stop childbearing, but only 2.4% of men around the world use this method. We conducted an extensive review of the vasectomy research literature and programmatic reports, published between April 2005 and April 2015, to synthesize barriers and facilitators to vasectomy adoption. Of the more than 230 documents in...

OBJECTIVE To determine whether vasectomy is associated with an increased risk of several diseases, and in particular testicular cancer, after operation. DESIGN Retrospective cohort study using linked medical record abstracts. SETTING Six health districts in Oxford region. SUBJECTS 13,246 men aged 25-49 years who had undergone vasectomy between 1970 and 1986, and 22,196 comparison subjects...
