JF The British Journal of Venereal Diseases JO Br J Vener Dis FD BMJ Publishing Group Ltd SP 307 OP 309 DO 10.1136/sti.51.5.307 VO 51 IS 5 A1 Berger, G S A1 Keith, L A1 Moss, W YR 1975 UL http://sti.bmj.com/content/51/5/307.abstract AB Among 2,005 women attending a contraceptive clinic 9-3 per cent. were found to have gonorrhoea. When these women were classified according to the method of contraception used at the time of their initial visit to the clinic, the following prevalence of gonorrhoea was observed: oral contraceptives 11-5 per cent., intrauterine contraceptive devices 9-9 per cent., barrier methods (condom-diaphragm-foam) 4-2 per cent. These differences are statistically significant. The authors suggest that the additional protective advantage of barrier methods should be considered when the physician and patient are selecting appropriate methods of contraception.
