Abstract

PURPOSE

This prospective observational study evaluated the bleeding patterns of adolescents receiving a monthly injectable contraceptive containing norethisterone enanthate 50 mg plus estradiol valerate 5 mg.

MATERIALS AND METHODS

The study enrolled 73 volunteers aged between 14 and 19 years; of these patients, 38 (52%) recorded their menstrual cycles during 1 year.

RESULTS

After 1 year of using the contraceptive, most of the 38 women (71.1%) had adequate menstrual patterns (two to four bleeding episodes; none lasting 10 days or longer; with a range of bleeding-free intervals not exceeding 17 days), 23.7% reported prolonged bleeding episodes, 2.6% had irregular bleeding and 2.6% had amenorrhea. Only 1 of the 38 teenagers is known to have discontinued the method due to bleeding. Among these 38 adolescents, dissatisfaction with bleeding patterns was not a frequent reason given for discontinuation of the monthly injectable contraceptive.

摘要

目的

这项前瞻性观察性研究评估了接受含50毫克庚酸炔诺酮加5毫克戊酸雌二醇的每月注射用避孕药的青少年的出血模式。

材料与方法

该研究招募了73名年龄在14至19岁之间的志愿者；在这些患者中，38名（52%）在1年内记录了她们的月经周期。

结果

使用避孕药1年后，38名女性中的大多数（71.1%）月经模式正常（有两到四次出血事件；没有一次持续10天或更长时间；无出血间隔时间范围不超过17天），23.7%报告有出血时间延长的情况，2.6%有不规则出血，2.6%有闭经。已知38名青少年中只有1人因出血而停用该方法。在这38名青少年中，对出血模式不满意并不是停用每月注射用避孕药的常见原因。
