Nuevas recomendaciones para el consejo anticonceptivo basadas en el estilo de vida. Resultados de un estudio Delphi

“…El anillo vaginal, que libera 15 mg de EE y 120 mg de etonogestrel, ha demostrado en numerosos estudios un excelente control del ciclo 10,11 . Así, el control del ciclo inducido por el anillo vaginal es superior al de los ACO, tal y como demuestran los estudios comparativos llevados a cabo con píldoras con 30 mg de EE y 150 mg de levonorgestrel y con 30 m de EE y 3 mg de drospirenona 12,13 .…”

Efficacy, safety, and patient acceptability of the etonogestrel and ethinyl estradiol vaginal ring

“…24 In two studies, the comparator was an oral contraceptive with 30 µg of EE and 150 µg of LNG. 25,26 In the other study, the ring was compared with two different pills, one with 20 µg of EE and 100 µg of LNG, and the other with 15 µg of EE and 60 µg of gestodene. 27 The percentage of women with intermenstrual bleeding in the four studies ranged from 1.1%-9.5%, in the ring groups, and from 3.5%-35.8% in the pill groups.…”

New technologies in contraception

“…44,45 Evidence from both clinical studies and clinical experience programmes shows better cycle control than with the combined pill. [46][47][48][49] The ring can, however, cause leucorrhoea, vaginal discomfort, vaginitis and ring-related events comprising foreign body sensation, coital problems and expulsion. 44,45 Nestorone rings have undergone preliminary investigation by the Population Council.…”
