This prospective study found that women with luteal phase defect exhibited significantly higher corpus luteum blood flow resistance indices than normal women, suggesting color flow pulsed Doppler analysis may aid in assessing luteal phase adequacy.

Abstract

ObjectiveTo determine whether color flow pulsed Doppler analysis of corpus luteum blood flow in normal cycles differs from cycles with a luteal phase defect.DesignA prospective study of natural ovarian cycles.SettingThe University of Vermont Reproductive Endocrinology and Infertility Service.PatientsTen women with regular menstrual cycles and at risk for luteal phase defect (LPD) four with unexplained infertility, two with recurrent abortion, and four with age > 35 years.InterventionsAll women were examined by transvaginal color flow pulsed Doppler during the early follicular, late follicular, early luteal, midluteal, and late luteal phase of the menstrual cycle. Venous blood for P concentration was drawn on each day of Doppler exam. Urine testing for LH surge and endometrial biopsy during the late luteal phase were performed on each patient.Main outcome measuresLowest resistance index associated with the highest amplitude signal from intraovarian vessels of each ovary, dated endometrial biopsies, serum P.ResultsMean resistance indexes in LPD patients (n = 3) were significantly higher compared with normal women (n = 6) throughout the follicular and luteal phases. One patient remained anovulatory and was excluded from statistical analysis. Although systolic and diastolic velocities generally were observed to be lower in LPD patients compared with normal women, these differences were not statistically significant. High correlations were observed between P and resistance index within each luteal time point, achieving its highest value during the midluteal phase.ConclusionsThis initial study provides evidence that color flow pulsed Doppler analysis of blood flow impedance to the corpus luteum may aid in assessing luteal phase adequacy.
