High prevalence of vasectomy in New Zealand

Vasectomy and Risk of Prostate Cancer

“…The prevalence of vasectomy in controls, adjusted to the age distribution of New Zealand European men aged 40 to 74 years, was 44%. 12 A history of vasectomy was less common among cases than controls, although this was not statistically significant (RR, 0.92; 95% CI, 0.75-1.14). Adjustment for social class, geographic region, religious affiliation, and a family history of prostate cancer had little effect on the RR of prostate cancer from vasectomy (RR, 0.92; 95% CI, 0.74-1.13).…”

‘I’m committed to her and the family’: positive accounts of vasectomy among New Zealand men

“…While the use of different data can make comparisons difficult (Amor et al, 2008;Pile & Barone, 2009), there is agreement that New Zealand has had a very high prevalence of vasectomy since the 1970s (Pile & Barone, 2009;Sneyd, et al, 2001). Contemporary assessments suggest over 18% of adult men and more than 25% of married men opt to have the operation (Clifton, Kaneda, & Ashford, 2008;Sneyd, et al, 2001). The numbers are highest at early middle age (i.e.…”

“…40-49), 57% in the single comprehensive study on New Zealand's vasectomy uptake (Sneyd et al, 2001). New Zealand is also one of the very few countries where vasectomy has surpassed tubal ligation as a preferred method of sterilisation (Pile & Barone, 2009;Sneyd et al, 2001;UN, 2003UN, , 2007. Currently New Zealand, Australia and Canada vie for the 'top spot' for vasectomy uptake, comfortably well ahead of all other countries (Clifton et al, 2008).…”

Assessment of needs of men for decision support on male sterilization

“…Vasovasostomy, performed in 1-3% of men who had a vasectomy [4][5][6], partially estimates the extent of decisional regret after vasectomy. Studies have shown that between 7% and 10% of men and/or couples who choose vasectomy as a contraceptive method experience decisional regret [7][8][9][10].…”
