28 lut 2022 · IUD expulsions were analyzed in the full study cohort by postpartum timing interval at insertion and in the subcohort of women with breastfeeding status. We estimated incidence rates, cumulative incidence, and crude and adjusted hazard ratios (HRs) and their 95% CIs for risk of IUD expulsion.
The risk of uterine perforation is increased in women who have recently given birth, and in women who are breastfeeding at the time of insertion. In a large US retrospective, postmarketing safety study of IUDs, the risk of uterine perforation was highest when insertion occurred within ≤6 weeks postpartum, and also higher with breastfeeding at ...
29 kwi 2022 · The 52-mg levonorgestrel-releasing intrauterine system maintains an excellent safety profile and contraceptive efficacy through 8 years. For years 6 to 8, the 3-year Pearl Index (95% confidence interval) was 0.28 (0.03–1.00) with a 3-year cumulative failure rate of 0.68% (0.17–2.71).
15 cze 2024 · Three hundred twenty lactating women were randomized to either an IUD containing levonorgestrel (Mirena; n = 163) or the copper-containing IUD Cu T380A group (n = 157). Follow-up of infants for 1 year found no differences in growth and development or in duration of breastfeeding.
The post-partum subcohort of individuals with breastfeeding information had 673 uterine perforations (62% complete), with a 5-year cumulative incidence of 1·37% (95% CI 1·24–1·52) and an increased risk with breastfeeding (aHR 1·37, 95% CI 1·12–1·66).
4 cze 2022 · The post-partum subcohort of individuals with breastfeeding information had 673 uterine perforations (62% complete), with a 5-year cumulative incidence of 1·37% (95% CI 1·24–1·52) and an increased risk with breastfeeding (aHR 1·37, 95% CI 1·12–1·66).
a large US retrospective, postmarketing safety study of IUDs, the risk of uterine perforation was highest when insertion occurred within ≤6 weeks postpartum, and also higher with breastfeeding at the time of insertion. The risk of perforation may be increased if Mirena is inserted when the uterus is fixed, retroverted or not completely involuted.
