Infertility in Males01:23

Infertility in Males

262
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...

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.
Endometriosis, a condition characterized by abnormal growth of...

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...

科学领域:

  • 生殖医学 生殖医学
  • 临床流行病学临床流行病学
  • 生物统计学 生物统计学

背景情况:

  • 无法解释的不孕症诊断带来了一个困境,平衡不确定性与自然受孕潜力.
  • 如果所有病例都接受立即干预,过度治疗是有风险的.
  • 预测模型可以估计自然受孕的可能性,帮助治疗决策.

研究的目的:

  • 评估预测模型在指导治疗决策的有效性,对夫妇有不明原因的不孕不育.
  • 为了确定预测模型是否优化生育结果,并限制不必要的干预.

主要方法:

  • 一项对25项评估自然受精预测模型的研究的系统综述,用于无法解释的不孕不育.
  • 分析重点是模型导出,验证和影响评估.
  • 包括随机临床试验来评估模型对治疗结果的影响.

主要成果:

  • 胡纳尔特模型结合了女性年龄,不孕持续时间,先前的怀孕和精子运动,尽管歧视有限,但显示出出色的校准.
  • 对于12个月自然受精率>30%的不明原因不孕症,即时子宫内受精 (IUI) 和受控的卵巢过度刺激并不优于预期的管理.
  • 在30%门以下,IUI优于预期的管理,但即时体外受精 (IVF) 对IUI没有优势.

结论:

  • 延迟治疗适用于无法解释的不孕症病例,自然受孕的预后良好.
  • 对于预后不佳的病例,需要立即治疗,包括控制卵巢过度刺激的IUI.
  • 将预测模型集成到临床实践中可以优化治疗选择,最大限度地提高生育结果,并最大限度地减少过度治疗.
