概括
居住地与森林大火相邻并没有显著影响辅助生殖技术 (ART) 的结果. 这项研究发现,生活在野火附近与ART周期成功率 (包括怀孕和活产) 之间没有联系.
科学领域:
- 生殖医学 生殖医学
- 环境健康 环境健康
- 流行病学 流行病学
背景情况:
- 全球森林大火事件的发生率和严重程度不断增加,引发了人们对其对公共卫生潜在影响的担忧.
- 环境曝光对生殖健康的影响,如林火灾烟雾,尚不清楚.
- 辅助生殖技术 (ART) 周期是潜在的环境影响生育结果的敏感时期.
研究的目的:
- 调查澳大利亚维多利亚州林大火附近的住宅是否与ART循环结果有关.
- 为了比较居住在附近和远离野火事件的参与者之间的ART结果 (例如受精,怀孕,活产率).
- 探索野火事件发生后的时间与ART成功率之间的潜在相关性.
主要方法:
- 一个回顾性队列研究分析了2001个ART周期从2019年7月到2020年6月在维多利亚莫纳什试管婴儿诊所.
- 参与者按周期日期 (森林火灾前或之后的事件) 和住宅邮编附近 (近邻或非近邻的活火) 分层.
- 统计分析包括ANOVA,克鲁斯卡尔-瓦利斯,费舍尔的精确测试,概括估计方程和后勤/回归分析,以评估ART结果和时间相关性.
主要成果:
- 在森林火灾后的近邻和非近邻群体之间,没有观察到获得/受精的卵细胞数量,使用的胚胎或受精率,利用率,临床怀孕和活产率的显著差异.
- 当在近邻和非近邻住宅群体内比较火灾前和火灾后的周期时,ART结果仍然相似 (P > 0.1).
- 相关性分析显示,在近邻与非近邻组的火灾后,胚胎利用率随时间推移呈现出非统计学意义上的趋势 (R2 = 0.080.09,P ≈ 0.06).
结论:
- 住宅附近发生重大野火事件与ART结果在时间和临床匹配周期中的显著变化无关.
- 这些发现表明,与野火相邻的短期暴露可能不会对关键的ART指标产生不利影响.
- 鉴于全球大火事件的频率和强度不断上升,需要进一步的研究来调查潜在的长期生殖健康与林火灾暴露的关联.

Infertility in Females
3.6K
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.

Infertility in Males
522
Male infertility affects millions of couples worldwide, arising from various factors that impact different stages of the reproductive process. An endocrine imbalance resulting from conditions like hypogonadism, Klinefelter syndrome, or pituitary disorders can disrupt hormone levels and reduce sperm production. Testicular defects, such as tumors, cryptorchidism, atrophic testes, abnormal sperm morphology, and low sperm count or motility, may arise due to genetic factors, structural...
