To assess sexual function of first-time users of the contraceptive ring and contraceptive patch.
Open-label randomized trial.
Multicenter study.
PATIENT(S): A total of 500 healthy, premenopausal, nonpregnant women who had recently used combined oral contraceptives.
INTERVENTION(S): Contraceptive ring vs. contraceptive patch.
MAIN OUTCOME MEASURE(S): Subjects completed the Female Sexual Function Index (FSFI) before randomization to the study product and after 3 months. Unadjusted and adjusted changes in total and domain FSFI scores from baseline to exit were compared between treatment groups using linear regression (intention-to-treat approach).
RESULT(S): Final adjusted mean total FSFI scores increased by 0.32 points in the patch group and decreased by 0.74 points in the ring group. Subjects in the ring group had worsening scores in the areas of arousal (score change -0.169 ring vs 0.010 patch), lubrication (score change -0.202 ring vs. 0.031 patch), and pain (score change -0.162 ring vs. 0.182 patch).
CONCLUSION(S): Among recent combined oral contraceptive users, slight decrements in sexual function scores were noted with contraceptive ring use overall and in several domains of sexual functioning, whereas slight increases were noted with patch use. However, for both products, these changes are not likely to be clinically significant.
评估初次使用避孕环和避孕贴的女性的性功能。
开放性、随机试验。
多中心研究。
500 名健康、绝经前、未怀孕的近期使用复方口服避孕药的女性。
避孕环与避孕贴。
受试者在随机分组至研究产品前和 3 个月后完成女性性功能指数(FSFI)。使用线性回归(意向治疗方法)比较两组治疗组之间从基线到退出时总 FSFI 和各领域 FSFI 评分的未调整和调整后变化。
最终调整后的平均总 FSFI 评分在贴剂组中增加了 0.32 分,在环组中降低了 0.74 分。环组在唤起(评分变化-0.169 环 vs 0.010 贴)、润滑(评分变化-0.202 环 vs. 0.031 贴)和疼痛(评分变化-0.162 环 vs. 0.182 贴)等领域的评分恶化。
在近期使用复方口服避孕药的女性中,使用避孕环总体上和在几个性功能领域的性功能评分略有下降,而使用贴剂则略有增加。然而,对于这两种产品,这些变化不太可能具有临床意义。
