The main purpose of trials for the evaluation of new contraceptive methods is to test their effectiveness, and therefore only women below 38 years of age are accepted. Furthermore, when new methods are being tested, only healthy women are accepted, and those having health problems of almost any kind are excluded. Therefore our knowledge about the contraceptive methods in women over 40 years of age is scanty and comes from trials with a long\u2010lasting follow\u2010up on healthy women who can use the method without problems until they are 45 or reach menopause. We have very limited reported information on the use of contraceptives by women who have cardiovascular disease, diabetes, liver problems, etc. Therefore the main body of experience in this review comes from healthy women between 35 and 44. On the other hand, one should remember that these women have a high motivation to use contraceptive methods and therefore the continuation rate in the trials is high. This compensates for the relatively small number of acceptors by giving more women\u2010years in follow\u2010up. Continuation rate and the proper use of methods are directly correlated to increase in age, socioeconomical status, and to education of users. Highly educated women in this age group have very low failure rate with almost any method.<\/jats:p>","DOI":"10.3109\/00016349209009913","type":"journal-article","created":{"date-parts":[[2007,11,13]],"date-time":"2007-11-13T19:09:04Z","timestamp":1194980944000},"page":"169-174","update-policy":"http:\/\/dx.doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":10,"title":["Contraception after thirty\u2010five"],"prefix":"10.1111","volume":"71","author":[{"given":"Tapani","family":"Luukkainen","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2011,1,7]]},"reference":[{"key":"e_1_2_1_2_1","first-page":"841","article-title":"Efficacy of different contraceptive methods","volume":"1","author":"Lawless Vessey M.
