A single human chorionic gonadotropin determination was performed in 786 infertile women during the late luteal phase to determine the frequencies of preclinical abortions and whether the frequency was increased in women with endometriosis. Thirty-seven pregnancies (4.7% of cycles) were identified, of which six were classified as preclinical abortions (0.8%). In women with endometriosis, the frequency of preclinical abortions was 0.9% and was not statistically different from other infertile subgroups. This study suggests that preclinical abortions are not cause of infertility in either an infertile population as a whole or in the subgroup of women with endometriosis.
在786名不孕妇女的黄体晚期进行了单次人绒毛膜促性腺激素测定，以确定临床前流产的发生率以及子宫内膜异位症患者的发生率是否增加。共识别出37次妊娠（占周期的4.7%），其中6次被归类为临床前流产（0.8%）。在子宫内膜异位症患者中，临床前流产的发生率为0.9%，与其他不孕亚组无统计学差异。这项研究表明，临床前流产在整个不孕人群或子宫内膜异位症女性亚组中均不是不孕的原因。
