title: Diagnosis of luteinized unruptured follicle by ultrasound and steroid hormone assays in peritoneal fluid: a comparative study.
abstract: Luteinized unruptured follicle detection was carried out in 27 women by means of ultrasound scans three times per day and estimation of 17 beta-estradiol and progesterone levels in peritoneal fluid. The incidence of luteinized unruptured follicle diagnosed by ultrasound was 2 of 27 and by estimation of steroid levels was 8 of 27. In three women, a follicle-like structure appeared within 24 hours after ovulation was established by ultrasound; this was accompanied by extremely low progesterone levels in the peritoneal fluid. The disparity between these methods requires further evaluation.
