title: The measurement of steroid hormones in endometrial tissue: a comparison between two methods of extraction.
abstract: Concentrations of oestrone, oestradiol, 5-androstene-3 beta,17 beta-diol (androstenediol) and dehydroepiandrosterone (DHA) were measured in human endometrium by radioimmunoassay following extraction with either diethyl ether or ethanol-acetone. Our results demonstrate that there is no difference between values obtained using these methods of extraction.
