概括
在植入前遗传测试 (PGT) 周期中,增加总性淋巴激素 (Gn) 剂量并没有影响欧普洛伊德母细胞母细胞的发病率. 随着年龄的增长和结构重组的PGT与较低的胚胎细胞形成率和euploid率有关.
科学领域:
- 生殖医学 生殖医学
- 遗传学 遗传学 是一个
- 不孕症研究 不孕症研究
背景情况:
- 植入前遗传检测 (PGT) 涉及在移植之前对胚胎进行遗传异常的评估.
- 确定最佳刺激方案,包括淋巴激素 (Gn) 剂量,对于最大限度地提高PGT成功率至关重要.
- 在PGT循环中,总Gn剂量与欧囊胚胎细胞发育率之间的关系需要进一步阐明.
研究的目的:
- 为了研究增加总性淋巴激素 (Gn) 剂量和经过植入前遗传测试 (PGT) 的卵细胞中欧普洛伊德胚胎细胞率之间的关联.
主要方法:
- 回顾性队列研究分析了2017-2022年在一个生殖医学中心的19246个卵细胞.
- 卵子细胞根据在受控卵巢刺激 (COS) 期间给予的总Gn剂量的三截面定量进行分组.
- 包括PGT循环用于形积分,单基性疾病和结构重组,通过下一代测序平台进行染色体分析.
主要成果:
- 总Gn剂量与囊胚形成的增加或减少或欧囊胚形成率没有明显的相关性.
- 年龄的增长被确定为减少胚胎细胞形成和euploid率的重要风险因素.
- 结构重组的PGT与较低的胚胎细胞形成和euploid率相关,而 aneuploidy的PGT相比.
结论:
- 总性腺激素 (Gn) 剂量似乎不会影响PGT周期中的胚胎囊形成或euploid速率.
- 提前的孕产妇年龄和接受PGT进行结构重组是成功的胚胎细胞发育和euploidy的显著负面预测因素.
- 这些发现表明,要关注患者特定的因素,如年龄,而不是仅仅调整 Gn 剂量以优化 PGT 结果.

Oogenesis
63.6K
In human women, oogenesis produces one mature egg cell or ovum for every precursor cell that enters meiosis. This process differs in two unique ways from the equivalent procedure of spermatogenesis in males. First, meiotic divisions during oogenesis are asymmetric, meaning that a large oocyte (containing most of the cytoplasm) and minor polar body are produced as a result of meiosis I, and again following meiosis II. Since only oocytes will go on to form embryos if fertilized, this unequal...

In Vitro Fertilization
239
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...
