Thirty-three infertile patients presenting spontaneous ovulatory cycles with long follicular phases (greater than or equal to 20 days) underwent a luteal function evaluation by basal body temperature, plasma progesterone (P), estradiol, and prolactin determination, and endometrial biopsy study. An endometrial luteal phase deficiency (LPD) was detected in 13 patients (39.4%), although in 10 of them (77%) P levels were normal. This study shows a high incidence of endometrial LPD among cycles with delayed ovulation and that in cases of LPD related to abnormal folliculogenesis, the endometrium is a better indicator than plasma P.
33例有自发排卵周期且卵泡期长（大于或等于20天）的不孕患者接受了黄体功能评估，评估方法包括基础体温测定、血浆孕酮（P）、雌二醇和催乳素测定以及子宫内膜活检研究。13例患者（39.4%）检测到子宫内膜黄体期缺陷（LPD），尽管其中10例（77%）的P水平正常。本研究表明，排卵延迟的周期中子宫内膜LPD的发生率很高，并且在与卵泡发生异常相关的LPD病例中，子宫内膜比血浆P是更好的指标。
