概括
仅靠植入前遗传检测 (PGT) 无法确保怀孕. 一个新的基于RNA-seq的子宫内膜受体测试 (rsERT) 与PGT相结合,改善了结果,解决了不育患者的植入失败问题.
科学领域:
- 生殖医学 生殖医学
- 遗传学 遗传学 是一个
- 内分泌学 在内分泌学.
背景情况:
- 植入前遗传检测 (PGT) 可以识别遗传疾病,但不能保证植入成功.
- 植入失败可能源于子宫内膜受体 (ER) 异常,独立于胚胎质量.
- 目前的PGT方法无法解决已知遗传病症患者的ER问题.
研究的目的:
- 为了验证一种基于RNA-seq的新型ER测试 (rsERT),以改善辅助生殖技术 (ART) 的结果.
- 在不孕症患者中评估rsERT指导的个性化胚胎移植 (pET) 的疗效.
- 为了调查一个患有多发性内分泌新生病1型 (MEN1) 和ER异常的不孕症患者的病例.
主要方法:
- 追溯队列研究涉及511个PGT周期.
- 一种新开发的基于RNA-seq的ER测试 (rsERT) 的验证.
- 基于rsERT预测的个性化胚胎移植 (pET) 在MEN1患者的应用.
主要成果:
- 个性化胚胎移植 (pET) 组显示,临床怀孕率 (69.7%,P = 0.035) 显著改善.
- 一名 MEN1 患者在 PGT-M 后通过 pET 实现了健康的活产,在 rsERT 的指导下实现了最佳的植入时间.
- 在患者的mRNA变体和MEN1基因之间没有发现强烈的关联.
结论:
- 将rsERT与PGT集成,可以提高ART的成功率.
- 对子宫内膜接受度 (ER) 的评估对于不育的患者至关重要,特别是那些患有内分泌疾病的患者,如MEN1.
- MEN1诱导的内分泌功能障碍,而不是MEN1突变本身,似乎导致ER异常.

Infertility in Males
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
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.
