The association between vasectomy and prostate cancer: a systematic review of the literature

Medical history, body size, and cigarette smoking in relation to fatal prostate cancer

“…Positive associations have been reported with longer time since vasectomy [30,[32][33][34][35], older age at vasectomy [28,36], and younger age at prostate cancer diagnosis [37]. It has been suggested that detection bias and ascertainment bias may have produced an upward bias in the relative risk in these studies [17,31,38]. To our knowledge, the present study is the first to examine the association between vasectomy and prostate cancer mortality.…”

“…Some prior case-control and cohort studies [17,28] reported a positive association between vasectomy and incident prostate cancer, but others did not; [17,29] two meta-analyses drew different conclusions [30,31]. Positive associations have been reported with longer time since vasectomy [30,[32][33][34][35], older age at vasectomy [28,36], and younger age at prostate cancer diagnosis [37].…”

Repercussions of castration and vasectomy on the ductal system of the rat ventral prostate

“…Although some studies have indicated increased risk of prostate cancer in vasectomized men (Giovanucci et al, 1993a,b;Emard et al, 2001), another study reports that vasectomy decreases the relative risk (Ross et al, 1983), while others infer that there is no association between vasectomy and prostate cancer (Bernal-Delgado et al, 1998;Lesko et al, 1999;Cox et al, 2002).…”

Sociología de la práctica médica autoritaria: violencia obstétrica, anticoncepción inducida y derechos reproductivos

“…Pese a que la información que vinculó a la vasectomía con el cáncer testicular y la disminución de la libido ya fue rebatida (Goldacre, Wotton, Seagroatt y Yeates, 2005;Bernal-Delgado, Latour-Pérez, Pradas-Arnal y Gómez-López, 1998), la idea de que ésta se relaciona con el cáncer permanece. En las entrevistas también pervive el temor de que la vasectomía puede llegar a asociarse con el desarrollo de enfermedades auto-inmunes:…”
