It has been suggested that the chronologic date of an endometrial biopsy performed to evaluate luteal adequacy should be based on the date of the luteinizing hormone surge rather than the date of the next menstrual period. Sixty-four infertile women used a urinary luteinizing hormone immunoassay to identify the luteinizing hormone surge; timed serum progesterone level tests and an endometrial biopsy were then performed. An out-of-phase endometrium was identified in 26.6% of cycles dated traditionally and 28.1% of cycles dated from the luteinizing hormone surge. No relationship was identified between progesterone levels and endometrial biopsy results when the next menstrual period was used. When the luteinizing hormone surge was used no progesterone cutoff value could be identified that would reliably distinguish between in-phase and out-of-phase cycles. Use of a urinary luteinizing hormone immunoassay offers no advantage over the next menstrual period and does not lead to better agreement between histologic and chronologic dating.
OBJECTIVE: We attempted to clarify the relationship between luteinized unruptured follicle, which occurs in the early stages of endometriosis, and unexplained infertility. STUDY DESIGN: Seventy patients who had unexplained infertility were reviewed. RESULTS: Laparoscopic examination showed that 47 patients (67%) had endometriosis; of these, 40 (85%) had minimal or mild disease. The incidence of luteinized unruptured follicle was higher (p < 0.05) in patients who had endometriosis (35%/patient and 25%/cycle) compared with patients who did not have endometriosis (11%/patient and 7%/cycle). Degenerated oocyte cumuli were collected in 6 (43%) of 14 luteinized unruptured follicles diagnosed by transvaginal ultrasound. CONCLUSIONS: These results show that luteinized unruptured follicle is common in patients who have mild or minimal endometriosis and that it may be one of the causes of endometriosis-associated infertility. Transvaginal ultrasound-guided follicular puncture of luteinized unruptured follicle during the mid luteal phase may be useful in establishing a definitive diagnosis of luteinized unruptured follicle.
