This instrument indicates the highest retention force (HRF) in newtons (N). Ages of the women ranged from 17-50 years. The IUDs were fitted in nulligravidae (56%), nulliparous with 1 or more abortions (13%), primiparous (18%), and multiparous (13%) women. The IUDs used were the ML Cu 250-standard, 7 Cu 200, T Cu 200-adapted, with a shortened transversal arm of 15-30 mm and T Cu 200 standard. With the low expulsion rate, the ML Cu 250-standard IUD needed 5.8-5.4N and the 7 Cu 200 3.8-2.6N. The adapted T Cu 200 IUD needed 2.6-1.6N, i.e., about 1N more thant the T Cu 200-standard with an HRF of 1.7-1.0N. As the dynamomoeter only indicated the highest retention force, a retentiograph was devised to demonstrate the different retention forces and phases of the various IUDs by characteristic curves. The possible connections between retention and expulsion of IUDs are discussed. The retention forces of the different IUDs compared are congruent with the published expulsion rates. The retentiograph showed new patterns to test IUDs before they demonstrate side effects in vitro.</p>","PeriodicalId":84493,"journal":{"name":"Contraceptive delivery systems","volume":"3 2","pages":"107-16"},"PeriodicalIF":0.0,"publicationDate":"1982-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"22033990","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Lippes loops were inserted in 22 amenorrheic women who continued injectable contraception, and in 6 cases with prolonged postinjectable amenorrhea. The occurrence and rhythm of subsequent bleeding was recorded. IUD insertion induced bleeding in most cases of continued injectable users but it was usually irregular and unpredictable. It was regular in 6 subjects only while the IUD was in situ. After the removal of the IUD, the majority regained the state of amenorrhea within 3 months. Temporary IUD insertion had a positive impact on continuation (a mean additional rate of 18 months of use) among subjects who had wished to terminate the method because of amenorrhea. This procedure of temporary IUD insertion may serve to provide these women with an alternative contractive approach. In the postinjectable amenorrhea group, temporary IUD insertion induced bleeding during IUD application as well as after its removal, which was more predictable than that in the continued users. IUD insertion may facilitate return of regular menses and resumption of fertility in amenorrheic women who stop injectable contraception.</p>","PeriodicalId":84493,"journal":{"name":"Contraceptive delivery systems","volume":"3 2","pages":"127-33"},"PeriodicalIF":0.0,"publicationDate":"1982-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"22033992","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

No tablet failures were reported in large-scale multicenter trials. Clinical studies, confirmed by receptor studies, showed that desogestrel lacks androgenicity in the dosages used. Also, studies on lipid metabolism revealed that desogestrel does not abolish EE-induced rises in HDL cholesterol. Since low levels of HDL cholesterol have been associated with an increased risk of ischemic heart disease, this can be regarded as a favorable aspect of desogestrel. In view of increasing demands for safer OCs, it can be concluded that preference should be given to OCs containing this progestogen.</p>","PeriodicalId":84493,"journal":{"name":"Contraceptive delivery systems","volume":"3 1","pages":"11-5"},"PeriodicalIF":0.0,"publicationDate":"1982-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"22003733","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
