“…Since 1970s, color Doppler ultrasonography has been used during the menstrual cycle as a non-invasive method to monitor uterine and ovarian blood flow [3][4][5][6]. With the constant change and development of Doppler ultrasound, and a widespread use of this technique, uterine and ovarian arteries as well as endometrial, sub-endometrial, ovarian artery and ovarian stromal blood flow changes during the menstrual cycle have been shown [5][6][7][8].…”

Objectives: Blood flow to uterus and ovaries is demonstrated to be altered during mensturation. Studies has been published stating that blood flow differs also in ovulatory and anovulatory cycles. In this study, using color Doppler ultrasound, we aim to compare uterine, endometrial and ovarian blood flow during ovulatory and anovulatory cycles. Material and methods:Women volunteers who are aged between 18-40 had no endocrinological problem and not recieving exogenous hormone therapy were included to study. Blood levels of FSH, LH, E2, prolactine, DHEAS, free T4 were collected in early follicular phase. Uterina, subendometrial and intraovarian artery blood flow pulsatility and resistance indexes were analysed using Doppler USG technique. Patients were called out to control on 21st of cycle and progesterone levels were analysed. Patients who has ovulation signs in USG and progesterone level above 5 ng/mL were included to ovulatory cycle group. Patient who has no signs of ovulation in ultrasound and has not enough progesterone level were included to anovulatory cycle group.Results: LH and E2 levels were significantly higher in anovulatory patients. No correlation was found between endometrial blood flow resistance and basal E2, prolactine, testosterone levels. However, DHEAS levels were related to endometrial blood flow resistance in anovulatory cycles. No correlation was found between ovarian blood flow resistance/uterine blood flow resistance and basal E2, prolactine, testosterone, DHEAS levels. Conclusions:There is statistically significant difference between endometrial, ovarian, uterine artery blood flow resistance in ovulatory and anovulatory cycles. Blood flow resistance was found to be increased in anovulatory patients. Increased E2 levels in anovulatory cycles were related to endometrial linethickness and endometrial volume

“…A number of studies have reported on the use of color Doppler ultrasonography to assess differences in uterine blood flow impedance between fertile and infertile women (1,2) and to study uterine receptivity in women undergoing in vitro fertilization (3). Doppler ultrasonography has also been used to assess changes in blood flow to the uterus and ovaries during menstrual cycles (4)(5)(6)(7).…”

Purpose : Color Doppler imaging permits the accurate localization of vessels and highfrequency pulsed Doppler ultrasonography has improved the resolution of flow velocity waveforms. In this study, intraovarian arterial blood flow before and after follicle rupture in the natural cycle was examined using transvaginal color flow Doppler imaging and changes in intraovarian arterial resistance in relation to the outcome of infertility treatment was analyzed. Methods : In a prospective study, 227 spontaneous cycles in 118 infertile patients who were undergoing infertility treatment at the division of Reproductive Medicine in our center were recruited in this study. The impedance to flow in intraovarian vessels was measured by means of transvaginal color flow Doppler imaging during the periovulatory period in the natural cycle of all patients. The pulsatility index (PI) of intraovarian arterial blood flow and pregnancy rate was evaluated. Results : On the basis of PI values before and after follicular rupture, 227 cycles were classified into severely decreased (113 cycles) and not-severely decreased groups (114 cycles). The pregnancy rate per cycle in the severely decreased group was 18.6% (21/113), significantly higher than that in the not-severely decreased group (7/114; 6.1%, p = 0.004). The miscarriage rate was similar in the two groups. Conclusions : A reduction in intraovarian blood vessel resistance is necessary to achieve pregnancy in a natural cycle.
