OBJECTIVE To determine the frequency of and factors associated with delayed vasectomy success in men with first postvasectomy semen analysis showing motile sperm. DESIGN Descriptive study. SETTING One hospital-based family planning clinic and two private clinics from the Quebec City area, Canada. PATIENT(S) Three hundred nine men vasectomized between 1990 and 2001 and who had a first seme...

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-13246 men aged 25-49 years who had undergone vasectomy between 1970 and 1986, and 22196 comparison subjects who had...

In the past, family-planning programs have focused attention primarily on women, because of the need to free women from excessive child-bearing, and to reduce maternal and infant mortality through the use of modern methods of contraception. Most of the family-planning services were offered within maternal and child health (MCH) centers, most research and information campaigns focused on women a...

BACKGROUND Advocacy for male involvement in family planning has been championed over the years after the 1994 International Conference on Population and Development (ICPD). There are a few contraceptive methods for men, and vasectomy uptake has been identified as one of the indicators of male involvement in family planning. Vasectomy also known as male sterilization is a permanent form of contr...

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 Med...

BACKGROUND Even though several studies comparing vasectomy and cardiovascular disease (CVD) risk have been reported, most are small series with conflicting results. However, the extent of the risk is still uncertain. We therefore explored whether an association exists between vasectomy and CVD incidence and mortality. METHODS We searched PubMed, Embase, Web of Science, and Cochrane Library da...

The operation of vasectomy is a commonly performed procedure for male sterilisation. It should normally be a straightforward day case procedure undertaken by a competent medical practitioner under local anaesthesia. But how is competence assessed? General practitioners (GPs) have increasingly undertaken minor surgical procedures, and guidance to ensure an appropriate standard of care for patien...

OBJECTIVE To examine whether the observed difference in tubal sterilization rates between black and white women is dependent on racial/ethnic differences in vasectomy rates. DESIGN Secondary analysis of national, cross-sectional survey. SETTING 2002 National Survey of Family Growth. PATIENT(S) Women 15 to 44 years old with a current partner who were able to provide information about their...

OBJECTIVE To determine the percentage of patients with nonmotile sperm 12 weeks after vasectomy, to estimate the time needed for eventual azoospermia in these patients, and to record the percentage of patients with recurrence of nonmotile sperm after initial azoospermia after vasectomy. DESIGN A review of the semen analysis of vasectomies performed in a 2-year period. Semen analysis in a grou...

BACKGROUND Our understanding of early post-vasectomy recanalization is limited to histopathological studies. The objective of this study was to estimate the frequency and to describe semen analysis patterns of early recanalization after vasectomy. METHODS Charts displaying serial post-vasectomy semen analyses were created using the semen analysis results from 826 and 389 men participating in ...
