To analyze the presence of Y chromosome microdeletions in males of Mexican couples with idiopathic recurrent pregnancy losses (RPL).
Seventy-one males from couples with RPL and 66 fertile males as controls were studied. DNA was isolated from peripheral lymphocytes and used to run multiplex polymerase chain reactions. Regions AZFa (sY84, sY86), AZFb (sY127, sY134) and AZFc (sY254, sY255) of the Y chromosome were analyzed according to valid guidelines recommended by the European Academy of Andrology and the European Molecular Genetics Quality Network. Also, the sequence tagged sites (STSs): DYS262 (sY67), DYS220 (sY129), DYF85S1 (sY150), DYF86S1 (sY152) and DYF87S1 (sY153) were included in order to analyze STSs previously reported as deleted. A power analysis to support our simple size was performed.
Results show an absence of Y chromosome microdeletions in males of couples with RPL and controls with an acceptable statistical power.
The study did not show an association of recurrent pregnancy loss and Y chromosome microdeletions in Mexican male partners. Based on the results, the study of Y chromosome microdeletions in couples with RPL is not considered clinically relevant.
分析患有特发性复发性流产（RPL）的墨西哥夫妇中男性的Y染色体微缺失情况。
研究了71名来自复发性流产夫妇的男性以及66名可育男性作为对照。从外周血淋巴细胞中分离DNA，并用于进行多重聚合酶链反应。根据欧洲男科学会和欧洲分子遗传学质量网络推荐的有效指南，分析Y染色体的AZFa（sY84、sY86）、AZFb（sY127、sY134）和AZFc（sY254、sY255）区域。此外，还纳入了序列标签位点（STSs）：DYS262（sY67）、DYS220（sY129）、DYF85S1（sY150）、DYF86S1（sY152）和DYF87S1（sY153），以分析先前报道为缺失的STSs。进行了功效分析以支持我们的样本量。
结果显示，在患有RPL的夫妇中的男性以及对照中，均未发现Y染色体微缺失，且具有可接受的统计功效。
该研究未显示墨西哥男性伴侣的复发性流产与Y染色体微缺失之间存在关联。基于这些结果，对复发性流产夫妇进行Y染色体微缺失的研究在临床上不被认为具有相关性。
