Abstract
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.
