概括
通过比较受孕方法,辅助生殖技术 (ART) 产生的胎盘问题和不良结果的风险更高. 排卵诱导和次生育组为ART健康结果提供了更好的比较.
科学领域:
- 生殖医学 生殖医学
- 孕产妇和胎儿医学 孕产妇和胎儿医学
- 公共卫生 公共卫生
背景情况:
- 辅助生殖技术 (ART) 越来越多地用于不孕症.
- 了解ART怀孕产生的健康结果需要适当的比较组.
- 以前的研究经常使用肥沃的自然受孕分娩作为唯一的比较对象,可能掩盖了ART特定的风险.
研究的目的:
- 为了确定和描述适合的对比组对ART出生健康结果研究:排卵诱导 (OI),未经治疗的子育,和肥沃的自然受孕.
- 评估ART分娩的妊娠并发症和不良分娩结果是否高于非受精 (未经治疗和OI) 怀孕组.
主要方法:
- 链接西澳州和英联邦数据集,用于2003-2014年的出生 (≥20周).
- 在受孕群体 (ART,OI,未经治疗的亚肥沃,自然肥沃) 中比较人口特征,母亲的情况,产科史和怀孕并发症.
- 使用概括估计方程来计算单子妊娠并发症和分娩结果的调整风险比率 (aRR).
主要成果:
- 确定了9456例ART,3870例OI,11484例未经处理的子孕,以及303921例自然受孕.
- 经过OI和未经治疗的次生育群体与ART的特征比生育群体更多,尽管差异仍然存在.
- 单独治疗的ART患者患有胎盘问题 (例如,胎盘前aRR2.42) 和不良结果 (例如,早产aRR1.38) 的风险更高,而不是未经治疗的子育.
- 单独的OI显示出更高的孕前和妊娠糖尿病的风险,类似于次生育组.
结论:
- 排卵诱导和子育未经治疗的怀孕组是解释ART分娩健康结果的有价值的比较器.
- 怀孕并发症,特别是胎盘疾病和不良分娩结果在ART受孕后更为频繁.
- 这些发现强调了在ART研究中选择适当的比较组的重要性.

In Vitro Fertilization
259
In vitro fertilization (IVF) is a form of assisted reproductive technology where an egg is fertilized with sperm in a controlled laboratory environment before transferring the resulting embryo into the uterus. This process is designed to help individuals and couples experiencing difficulties conceiving.
The IVF process begins with ovarian stimulation, during which reproductive endocrinologists prescribe hormonal medications to stimulate the ovaries to produce multiple eggs instead of the single...

Birth Control Methods

Vasectomy is a surgical form of male sterilization that involves severing and sealing the vasa deferentia, preventing sperm from mixing with semen during ejaculation. Because a vasectomy does not impact the testes' ability to produce testosterone, hormone levels, libido, and sexual function generally remain unchanged. While vasectomy is highly effective in preventing pregnancy, with a success rate near 99.85%, rare cases of recanalization (spontaneous reconnection) can occur. Although...

Infertility in Females
292
Female infertility is defined as the inability to conceive after a year of regular, unprotected intercourse and affects about 10–15% of couples worldwide. The primary cause of female infertility is ovulatory disorders, which hinder the release of eggs. These disorders can be classified as hypothalamic amenorrhea, polycystic ovarian syndrome (PCOS), premature ovarian failure, and hyperprolactinemic anovulation disorders.
