Three of 24 infertile women with a short luteal phase transiently showed chorionic gonadotrophin (HCG) like immunoreactivity in serum as measured by the HCG-beta subunit radioimmunoassay. The plasma progesterone concentration was elevated above the lower normal postovulatory level in 2 of these women who also had elevated basal body temperature at the time HCG was detected. Positive HCG reaction coincided with the pre-ovulatory surge of luteinizing hormone (LH) in one patient, but in 2 other cases the LH concentration was low suggesting absence of LH interference. Our results suggest that some infertile women may conceive during their cycles with a short luteal phase and maintain pregnancy until HCG becomes detectable.
在24名黄体期短的不孕女性中，有3名通过人绒毛膜促性腺激素β亚基放射免疫测定法检测发现，血清中短暂出现了类似绒毛膜促性腺激素（HCG）的免疫反应性。其中2名女性的血浆孕酮浓度高于排卵后正常水平下限，在检测到HCG时，她们的基础体温也有所升高。1例患者的HCG阳性反应与促黄体生成素（LH）排卵前高峰同时出现，但在另外2例中，LH浓度较低，提示不存在LH干扰。我们的结果表明，一些不孕女性可能在黄体期短的周期中受孕，并维持妊娠直至检测到HCG。
