选择铜子宫内置器 (Cu-IUD) 的产后妇女更年轻,怀孕次数更多. 然而,使用Cu-IUD的女性怀孕回来的女性较少,而不是使用Depot medroxyprogesterone acetate (DMPA) 或没有避孕措施的女性.
科学领域:
- 生殖健康 生殖健康
- 流行病学 流行病学
- 避孕药是一种避孕药,用于避孕.
背景情况:
- 了解产后避孕选择对于计划生育和生殖健康结果至关重要.
- 产后立即期为启动长效可逆避孕药 (LARC) 和永久方法提供了一个关键的窗口.
- 有多种可用的避孕方法,包括铜子宫内避孕装置 (Cu-IUD),乙凝植入物 (ENG),输卵管结合 (TL) 和储存的美德基酸 (DMPA).
研究的目的:
- 确定选择各种产后避孕方法的妇女的流行病学概况:Cu-IUD,ENG,TL,DMPA或没有方法 (NCM).
- 为了比较Cu-IUD和DMPA与非方法选择 (非MAC) 的避孕有效性.
主要方法:
- 对HMU-SBC产后妇女的电子病历分析 (2016年1月 - 2020年12月).
- 流行病学概况和避孕选择 (Cu-IUD, ENG, TL, DMPA, NCM) 被记录下来.
- 通过跟踪返回第二次分娩的妇女,分析她们最初选择的产后方法,怀孕间隔和社会人口统计特征来评估避孕药的有效性.
主要成果:
- 从20896名妇女的数据显示,39%的妇女选择了Cu-IUD,2.5%的DMPA和52.5%的NCM.
- DMPA使用者更年轻 (26.5岁),而NCM使用者怀孕的次数更少 (2.2). TL用户的怀孕率最高 (3.8),而ENG用户的流产率最高 (1.6).
- 在再次怀孕的女性中,5.5%使用DMPA,6%使用NCM,只有2.3%使用Cu-IUD.
结论:
- 选择Cu-IUD插入的女性比不选择这种方法的女性更年轻,怀孕率也更高.
- 与DMPA或NCM使用者相比,Cu-IUD显示出更高的避孕效果,与DMPA或NCM使用者相比,回归孕妇的比例更低.
- 这些发现突出了与不同产后避孕方法相关的不同流行病学概况.

Hormonal Regulation of the Menstrual Cycle
At puberty, GnRH begins a pulsatile release pattern, which triggers the anterior pituitary gland to secrete follicle-stimulating hormone (FSH) and luteinizing hormone (LH). The frequency and amplitude of GnRH pulses vary across the menstrual cycle, with faster pulses favoring LH release and slower pulses favoring FSH...
