The progression of the prophase stages of meiosis in human foetal ovaries is reported from a series of aborted foetuses spanning the first two trimesters of gestation. A surface-spreading technique allowed cells to be examined at both light and electron microscope levels. The pachytene stage was specifically examined for evidence of synaptic or other abnormalities. Two observations of interest are the relatively high incidence with which errors of pairing occur and second the state of thickening observed when such unpaired axes are stained with silver.
本文报道了一系列妊娠前两个月流产胎儿的人类胎儿卵巢减数分裂前期阶段的进展情况。一种表面铺展技术使细胞能够在光学显微镜和电子显微镜水平上进行检查。特别检查了粗线期，以寻找突触或其他异常的证据。两个有趣的观察结果是配对错误发生的相对高发生率，以及当这种未配对的轴用银染色时观察到的增粗状态。
