Infertility in Males

295
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...

概括

近10%的男性患有阿佐精子症可以通过提供新鲜排泄的精子样本来避免微切割丸精子提取 (mTESE),用于细胞内质精子注射 (ICSI). 短暂的禁欲期可以改善有加密动物精子症的男性的精子运动性.

科学领域:

  • 生殖医学 生殖医学
  • 安德罗学与人类学
  • 不孕症治疗 不孕症治疗

背景情况:

  • 阴精症,以射精中缺少精子为特征,通常需要进行手术取精,如微剖析丸精子提取 (mTESE).
  • 内细胞质精子注射 (ICSI) 是克服男性不孕症的关键辅助生殖技术.
  • 在射精中识别可活性的精子可能会消除对侵入性手术的需要.

研究的目的:

  • 为了确定适合ICSI的精子在新鲜射精的精液样本中的流行率,这些精子来自预定接受mtESE的男性.
  • 评估短暂禁欲期对加密动物精子症男性的精液质量和ICSI结果的影响.

主要方法:

  • 一个学术医疗中心的回顾性队列研究.
  • 在2015年9月至2021年5月期间,对727名计划参加mtese的男性进行了分析.
  • 对ICSI和精液参数进行精射精子存在的评估.

主要成果:

  • 9.5%的计划中的mTESE手术被取消,因为在手术前的射精中发现了适合ICSI的精子.
  • 6.9%的男性在ICSI中使用了这些射精精子,每次试验实现了36%的活产率.
  • 较短的禁欲期 (<24小时) 与精子运动率的改善有关.

结论:

  • 在mTESE的当天提供新鲜的射精样本可以帮助近10%的亚精子症男性避免手术,并获得令人满意的ICSI结果.
  • 短时间内多次射精样本不会对精子度产生负面影响,并且可能会增强患有加密动物精子症的男性的运动性.
