Abstract
STUDY QUESTION Do infertile couples who recently utilized clomiphene citrate (CC) for ovulation induction or ovarian stimulation (<90 days previously) followed by a single euploid embryo transfer (SEET) have lower implantation potential compared with patients who were not exposed to CC within 90 days before embryo transfer (ET)? SUMMARY ANSWER There does not appear to be an association between recent CC exposure and lower implantation potential in patients who undergo a frozen embryo transfer (FET) of euploid embryos. WHAT IS KNOWN ALREADY Clomiphene has been found to be associated with lower pregnancy rates when compared against other ovarian stimulation medications. The majority of published research about the effects of CC on implantation potential suggest an anti-estrogenic effect on the endometrium. Quality evidence and information about utilization of CC and its effect on implantation potential after euploid ETs is lacking in the literature. STUDY DESIGN, SIZE, DURATION A retrospective cohort study with propensity score matching was carried out. We included all patients that underwent an autologous SEET from September 2016 to September 2022 at a single academic-private ART center. PARTICIPANTS/MATERIALS, SETTING, METHODS The study group included patients that had utilized CC during either ovulation induction cycles and/or controlled ovarian stimulation at least 90 days before FET. A propensity score-matched control group of patients that were unexposed to CC within 90 days prior to SEET was used for comparisons. The primary outcome was positive pregnancy test (defined as a positive serum β-hCG measured 9 days after ET), with other outcomes including clinical pregnancy, ongoing pregnancy, biochemical pregnancy loss, and clinical pregnancy loss rates per SEET. Multivariate regression analyses fitted with generalized estimating equations were utilized to analyze if there was an association between CC utilization and IVF outcomes. Furthermore, the study evaluated the cumulative effect of CC and endometrial receptivity in vivo and subsequent IVF outcomes. MAIN RESULTS AND THE ROLE OF CHANCE A total of 593 patients with utilization of CC in <90 days before ET were compared with 1779 matched controls. Positive pregnancy test rates were comparable among the control group and the CC exposed groups, respectively (74.3% versus 75.7%, P = 0.79), as were clinical pregnancy (64.0% versus 65.0%, P = 0.60), ongoing pregnancy (51.8% versus 53.2%, P = 0.74), biochemical pregnancy loss (15.7% versus 14.03%, P = 0.45), and clinical pregnancy loss rates were also comparable among cohorts (17.1% versus 18.1%, P = 0.71). No association was found between utilization of clomiphene and lower implantation rates (adjusted odds ratio 0.95, 95% CI 0.76-1.18). Also, no differences were observed in sub-analyses based on multiple CC utilization periods. Finally, no association was found between the number of consecutive cumulative clomiphene cycles and sub-optimal IVF outcomes. LIMITATIONS, REASONS FOR CAUTION The study has inherent bias that originated from its retrospective design. Serum levels of CC were not measured and sample size for the sub-analyses was small. WIDER IMPLICATIONS OF THE FINDINGS There does not appear to be an association between recent CC exposure and lower implantation potential in patients who undergo a FET of euploid embryos. This finding remains consistent, even in patients who undergo multiple, consecutive clomiphene cycles prior to ET. There were no long-term effects of CC on endometrial development and clinical characteristics examined in this study. Patients that utilized CC medication prior to a SEET cycle for either ovarian stimulation or ovulation induction, can be assured that there is no evidence of a residual effect of recent CC administration that could jeopardize their pregnancy probability. STUDY FUNDING/COMPETING INTEREST(S) No funding was received for the realization of this study. A.C. is advisor and/or board member of Sema4 (stakeholder in data) and Progyny.

Role of three-dimensional Doppler ultrasonography and leukemia inhibitory factor from endometrial secretion in predicting endometrial receptivity in IVF treatment: a pilot study. Arch Gynecol Obstet 2022; 306:259-265. [PMID: 35224652 PMCID: PMC9300517 DOI: 10.1007/s00404-022-06450-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/19/2021] [Accepted: 02/10/2022] [Indexed: 11/29/2022]
Abstract
Purpose This pilot study aimed to evaluate the potential synergistic role of three-dimensional power Doppler angiography ultrasound and the expression of Leukemia Inhibitory Factor (LIF) protein in predicting the endometrial receptivity of fresh In-Vitro Fertilization (IVF) cycles. Materials and methods This prognostic cohort study involved 29 good prognosis women who underwent fresh IVF cycles with fresh blastocysts transfer. Serial measurements of sub-endometrial parameters including vascularity index (VI), flow index (FI), and vascularization flow index (VFI) were conducted consecutively via power Doppler angiography on the day of oocyte maturation trigger, oocyte retrieval, and blastocyst transfer. Aspiration of endometrial secretion was performed on the day of embryo transfer. Results The mean index of VI and VFI on the trigger and oocyte retrieval day and also LIF protein concentration at the window of implantation were significantly higher in clinically pregnant women than that of the non-pregnant women (p < 0.05). The area under the curve (AUC) of VI and VFI was shown to have a powerful predictive value to forecast receptive endometrium on either trigger day (0.788 and 0.813, respectively) or oocyte retrieval day (0.813 and 0.818). Likewise, LIF concentration on the day of embryo transfer was adequate to become a predictor for endometrial receptivity (AUC 0.874). A combination of the VI and VFI on the trigger day and LIF concentration at specific cut-off values (VI > 5.381, VFI > 1.483, LIF 703.5 pg/mL) produced an algorithm with high AUC (0.881) and high specificity (94.4%) for an adequate prediction of non-receptive endometrium. Conclusion VI and VFI index assessed on maturation trigger day and the expression of LIF protein concentration at the window of implantation provided sufficient information to predict endometrial receptivity. A large randomized control trial is needed to validate these findings.

Abstract
Purpose The aim of the study was to evaluate the effect of clomiphene citrate on uterine artery blood flow using pulsed Doppler and endometrial and subendometrial micro vascularization using 3D power Doppler in unexplained infertility. Patients and methods In a prospective observational study at a university teaching hospital, the mid-luteal (peri-implantation) endometrial thickness and volume, uterine artery pulsatility index (PI) and resistance index (RI), endometrial and subendometrial vascularization index (VI), flow index (FI), and vascularization flow index (VFI), and serum estradiol and progesterone levels were compared between natural and clomiphene citrate stimulated cycles in the same group of 50 patients with unexplained infertility. Statistical analysis was done using paired t-test to compare different study variables. Results The primary outcome, which was the endometrial flow index, was significantly lower in the stimulated cycles (mean ± SD: 23.89±7.96 vs 27.49±8.73, mean difference (95% CI): −3.6 (−2, −5.9); P=0.03). The mean ± SD of endometrial thickness (10.92±3.04 vs 12.46±3.08 mm; P=0.01), volume (4.57±1.28 vs 5.26±1.32 cm3; P=0.009), endometrial VI (0.86±0.15 vs 0.95%±0.21%; P=0.02), VFI (0.25±0.08 vs 0.31±0.12; P=0.004), subendometrial VI (1.93±0.68 vs 2.26%±0.75%; P=0.02), FI (26.81±9.16 vs 30.73±9.87; P=0.04), and VFI (0.68±0.18 vs 0.79±0.21; P=0.006) were significantly lower in the stimulated cycles. However, there were no significant differences in the uterine artery PI (P=0.12) and RI (P=0.08) or serum estradiol (P=0.54) and progesterone (P=0.37) levels between natural and stimulated cycles. Conclusion Peri-implantation endometrial perfusion is significantly lower in clomiphene citrate stimulated cycles when compared to natural ones in patients with unexplained infertility.

Abstract
We aimed to compare ovarian (O), uterine (U) and spiral (S) artery (A) resistance of patients diagnosed as fertile, unexplained infertility (UI) and tubal factor infertility (TFI) in the peri-implantation period and independent from the impact of the treatment. UI (n = 70), TFI (n = 75) and fertile (n = 72) patients' ovarian, uterine and spiral artery pulsatility index (PI), resistance index (RI) and the endometrial thickness, serum estradiol and progesterone levels were compared. The specificity and sensitivity values were calculated according to determined cutoff values. Both TFI and control groups' UA PI values were significantly lower than the UI group's PI values. The highest UA RI values were found in UI group and the lowest values were in the control group. UI and TFI groups' OA PI/RI values were significantly higher than the control group. Both the control and TFI groups' SA PI/RI values were significantly lower than UI group's PI/RI values. UI patients' uterine and spiral arteries PI values >1.86 and >0.85, RI values >0.80 and >0.53 can be used as a valuable test showing reduced uterine perfusion. Ovarian artery PI values >0.96 and RI values >0.58 can be used as tests showing decreased ovarian perfusion in patients with TFI. In these patients, embryo cryopreservation can be considered.

Abstract
Background We conducted this prospective study to evaluate the prognostic significance
of uterine and ovarian artery Doppler velocimetry in clomiphene citrate (CC) cycles. Materials and Methods A total of 80 patients with unexplained infertility were given
100 mg/day of CC from day 3 to day 7 of their cycles in this current prospective study. On
cycle day 3, before administration of CC, each patient underwent Doppler transvaginal ultrasonography. The Doppler velocimetries of the right and left uterine and ovarian arteries were
recorded and analyzed in association with demographic and clinical parameters. Results TheThere were 6 out of 80 patients who became pregnant, the overall pregnancy
rate in this population was 7.5% for the current study. The cases were divided into two
groups according to whether they became pregnant or not. Demographic characteristics
showed no statistically significant differences between these groups (p>0.05). However,
the duration of infertility did show statistically significant differences between the groups.
Doppler velocimetry was not statistically significantly different between the two groups. Conclusion Doppler velocimetry of the uterine and ovarian arteries is not a factor in the
prognosis for pregnancy in CC cycles.

Abstract
OBJECTIVE The aim of this study was assessment of subendometrial blood flow with Doppler ultrasonography as an indicator of endometrial receptivity in stimulated cycles for intrauterine insemination (IUI). PATIENTS AND METHODS This prospective study enrolled 90 women scheduled for IUI after ovarian stimulation randomly assigned to one of the three equal groups; group (C) received Clomiphene citrate, group (H) received HMG and group (CH) received Clomiphene citrate in addition to HMG. All participants had ultrasound folliculometry starting on day 9, followed by transvaginal Doppler study of the subendometrial blood flow and perifollicular blood flow on the day of detecting at least one follicle >18 mm. Resistivity index (RI) and pulsatility index (PI) of subendometrial and perifollicular flow were measured. Endometrial thickness was measured on day of hCG injection. RESULTS Group (H) showed significantly higher frequency of subendometrial flow (80%) compared to the other two groups (p = 0.009). In cases of positive subendometrial flow, the RI and PI were significantly lower in group (H) compared to the other two groups (p = 0.007 and 0.012, respectively). Endometrial thickness was significantly lower in group (C) compared to group (H) (p < 0.001) and group (CH) (p < 0.001). Successful intrauterine implantation was documented in a total of 16 women (17.8%); the highest frequency was in group (H) (23.3%) and the lowest in group (C), however, the difference between the three groups was not significant (p = 0.372). Subendometrial indices and perifollicular RI were significantly lower in cases of successful implantation, while endometrium was significantly thicker in these cases (p < 0.001). CONCLUSION The presence of subendometrial flow is associated with successful IUI in women under stimulated cycles undergoing IUI. HMG seems a superior option for induction of ovulation regarding success of implantation.

Abstract
BACKGROUND The assessment of follicular maturity at the time of human chorionic gonadotropin (hCG) is one of the key factors for the success of all assisted reproductive techniques. AIM To assess follicles by three dimensional (3D) and 3D power Doppler (PD) before giving hCG to improve pregnancy rates in intrauterine insemination (IUI) cycles. DESIGN Prospective randomized study. MATERIALS AND METHODS Ultrasound for pre-hCG follicular assessment was performed over a period of 10 months for all 1000 cycles of IUI. Follicular assessment was performed using a transvaginal multifrequency volume probe. Follicles considered mature by 2D US and color Doppler were assessed by 3D and 3D PD. These values were independently evaluated for the conception and the non-conception groups. RESULTS Conception rates were 32.3 and 27% respectively and individually when the perifollicular resistance index was < 0.50 and the peak systolic velocity was > 11 cm/s 10-12 h before hCG. Conception rates of 32% were achieved with a follicular volume between 3 and 7 cc. The conception rate was 32.3% in the cumulus group. A perifollicular vascularity index of between six and 20 gave conception rates of 35% and perifollicular flow index of 27-43 gave conception rates of 33%. CONCLUSIONS 3D ultrasound is much more accurate for volume assessment of the follicle. Presence of cumulus increases the surety of the presence of a mature ovum in the follicle. 3D and 3D PD when used with 2D US and color Doppler for pre-hCG follicular assessment would definitely improve pregnancy rates in IUI cycles.

Abstract
OBJECTIVE To compare uterine and ovarian blood flow, measured by Doppler ultrasound, in the follicular phase of the menstrual cycle, in women who conceived to women who did not conceive during that cycle. DESIGN A prospective study of 192 women looking at markers of ovarian reserve between August 2000 and September 2002. SETTING A fertility clinic. PATIENT(S) A cross-section of women attending for fertility advice and treatment. INTERVENTION(S) Each woman was monitored during a natural cycle and then during a clomiphene challenge cycle (100 mg clomiphene given for 5 days from days 3-7 of the cycle). Doppler ultrasound scans were performed on days 3 and 12 of the natural cycle and day 11 of the clomiphene challenge cycle. MAIN OUTCOME MEASURE(S) Cycles in which women conceived were compared with those in which women did not conceive to see whether there were differences in uteroovarian blood flow parameters as measured by Doppler ultrasound scan in the follicular phase of the cycle. RESULT(S) In the 15 natural conception cycles there was an increased uterine artery peak systolic velocity at day 12 compared with 131 natural nonconception cycles (in which there was an opportunity to conceive). There were no differences in any uteroovarian blood flow parameters at day 3, and no differences in ovarian blood flow parameters (dominant follicle blood flow, dominant follicle pulsatility index), endometrial thickness or pulsatility at day 12. No differences were seen in any blood flow parameters in 10 clomiphene conception cycles compared with 116 clomiphene nonconception cycles. CONCLUSION(S) In the late follicular phase of natural conception cycles there is an increased uterine artery peak systolic velocity compared with nonconception cycles. This was not seen in clomiphene cycles in which conception occurred. There is very little in the literature comparing natural or clomiphene conception with nonconception cycles.

Abstract
OBJECTIVES To compare the effects of letrozole and clomiphene citrate (CC) on endometrial response in PCOS using subendometrial spiral artery Doppler. METHODS Fifty consecutive patients of anovulatory PCOS were recruited. Twenty-five patients (58 cycles) received 2.5-5 mg of letrozole; 25 patients (56 cycles) received 50-100 mg of CC (both orally on days 5-9 of menses). MAIN OUTCOME MEASURES number of dominant follicles, endometrial thickness (ET), spiral artery resistance index (RI) and pulsatility index (PI) and pregnancy rate. RESULTS The mean number of dominant follicles in letrozole group and CC groups was 1.63+/-1.02 and 1.62+/-0.96, respectively (P>0.05). The mean mid cycle ET was 6.9+/-0.74 mm in letrozole group and 5.9+/-0.53 mm in CC group (P<0.05). In letrozole and CC groups, the mean RI of spiral artery were 0.63+/-0.05 and 0.79+/-0.09, respectively, and the mean PI of spiral artery were 1.19+/-0.06 and 1.55+/-0.13, respectively. Both RI and PI in the letrozole group showed significant lower impedance compared to CC group (P<0.05). Pregnancy rate per cycle was 19% (11/58) in the letrozole group and 12.5% (7/56) in the CC group (P>0.05). CONCLUSION The effect of letrozole showed a significantly better endometrial response compared to CC.

Abstract
OBJECTIVE To examine the relationship between endometrial thickness and outcome of medicated frozen-thawed embryo replacement (FER) cycles. DESIGN A retrospective observational study. SETTING Assisted conception unit at a university hospital. PATIENT(S) All patients who underwent an FER cycle between 1997 and April 2006 and met the inclusion criteria. INTERVENTION(S) For endometrial preparation, a daily dose of 6 mg of oral E(2) valerate was started on menstrual day 1, and P pessaries (800 mg daily) were administrated when the endometrial thickness had reached 7 mm or more, with ET taking place 2-3 days later. The FER cycles were categorized according to endometrial thickness measurement on the day of P supplementation. MAIN OUTCOME MEASURE(S) Implantation, clinical pregnancy, ongoing pregnancy, and live birth rates. RESULT(S) In all, 768 consecutive medicated FER cycles were analyzed. The lowest pregnancy rates were associated with endometrial thickness <7 mm (n = 13) and >14 mm (n = 12; 7% in both groups). Significantly higher implantation (19% vs. 12%), clinical pregnancy (30% vs. 18%), ongoing pregnancy (27% vs. 16%), and live birth (25% vs. 14%) rates were achieved in cycles where endometrial thickness was 9-14 mm (n = 386), compared with those in which endometrial thickness was 7-8 mm (n = 357). These differences remained significant after adjusting for confounding variables (adjusted odds ratio [OR] = 1.83 [confidence interval {CI} = 1.3-2.6] for clinical pregnancy, 1.8 [CI = 1.2-2.6] for ongoing pregnancy and 1.9 [CI = 1.3-2.8] for live birth). CONCLUSION(S) In medicated FER cycles, an endometrial thickness of 9-14 mm measured on the day of P supplementation is associated with higher implantation and pregnancy rates compared with an endometrial thickness of 7-8 mm.

Abstract
Ultrasound examination of the endometrium is a commonly used non-invasive method to assess endometrial receptivity during in vitro fertilization (IVF) treatment. A good blood supply towards the endometrium is usually considered to be an essential requirement for implantation and therefore assessment of endometrial blood flow in IVF treatment has attracted a lot of attention in recent years. Doppler study of uterine arteries does not reflect the actual blood flow to the endometrium. Endometrial and subendometrial blood flows can be more objectively and reliably measured with three-dimensional power Doppler ultrasound. However, conflicting results are reported with regard to their role in the prediction of pregnancy in IVF treatment. Relevant studies in the literature differed in patients' characteristics, the day of ultrasound examination and the selection of the subendometrial region. As the degree of change in endometrial perfusion from the late follicular phase to the early luteal phase may be a more important determinant of endometrial receptivity, further studies should be conducted to determine the change in endometrial and subendometrial blood flows from late follicular phase to early luteal phase in order to delineate the role of endometrial and subendometrial blood flows in predicting IVF outcome.

Abstract
BACKGROUND Although follicular vascularity has been shown to be a good indicator of oocyte quality in IVF, scant evidence is currently available on the predictive value of this variable in terms of pregnancy rate during controlled ovarian stimulation (COS) and intrauterine insemination (IUI) cycles. METHODS Three-hundred and eighteen patients who had received mild COS underwent transvaginal ultrasound scan before performing the IUI. Using power Doppler imaging, vascularity of follicles with a mean diameter > or =16 mm was graded into a three grades according to the circumference of the follicle in which flow was identified. When more than one follicle was observed, grading was performed for all of them, and the highest vascularity grade was recorded. RESULTS Clinical pregnancy rate (number/total) in the low-, medium- and high-grade vascularity groups was 14.1% (14/99), 10.0% (10/100) and 11.8% (14/119), respectively (P = 0.66). Similar results were observed when only monofollicular cycles were considered. CONCLUSIONS Follicular vascularity does not predict the chance of pregnancy in women undergoing mild COS and IUI cycles.

Abstract
OBJECTIVE To determine whether ovarian perifollicular blood flow (PFBF) in the early follicular phase (EFP) was associated with treatment outcome. DESIGN Retrospective longitudinal cohort study. SETTING Tertiary referral centre/university hospital. PATIENTS Thirty-four women underwent 37 IVF cycles, which resulted in 35 embryo transfers. INTERVENTIONS Serial transvaginal scans using power Doppler ultrasound during the follicular phase. Ovarian PFBF of follicles > or =5 mm was subjectively assessed using a modified grading system (grades 0-4). MAIN OUTCOME MEASURES Ovarian PFBF and pregnancy. RESULTS Treatment cycles were retrospectively divided into two groups: Group 1 (n=20) had cycles with at least one small (5-10 mm) or medium (11-14 mm) size follicle(s) of high grade (2-4) PFBF on cycle day 5 or 6 or 7; and Group 2 (n=17), had cycles that did not. Group 1 had a significantly higher proportion of high grade large follicles in the late follicular phase (35% vs. 21%) (OR 2.0; 95% CI 1.1-3.7) and higher clinical pregnancy rate (47% vs. 12%) (OR 6.3; CI 1.1-35.7) compared to Group 2. CONCLUSION High grade ovarian PFBF in the EFP during IVF is associated with both high grade PFBF in the late follicular phase and a higher clinical pregnancy rate.

Abstract
Genital tuberculosis is reported to be a major pelvic factor causing infertility in Indian women and often exists without any apparent signs and symptoms. The role of latent tuberculosis in repeated IVF failure in unexplained infertility is examined. 81 women with unexplained infertility having repeated IVF failure tested for Mycobacterium tuberculosis using PCR, ZN staining and BACTEC-460 culture were selected. Fresh IVF-ET or frozen embryo transfer (FET) was attempted on patients successfully treated with anti-tubercular drugs (ATD). ATD-treated fresh cycles (group A1) and frozen cycles (group B1) were compared to previously failed fresh cycles (group A2) and FET attempts (group B2), respectively. Main outcome measures were gonadotropin required, terminal E2, number of oocytes retrieved, fertilization rate, embryo quality, endometrial thickness and sub-endometrial blood flow (V(max)). Gonadotropin required in group A1 was significantly less as compared to group A2. Number of oocytes retrieved and grade I embryos, endometrial thickness and V(max) were significantly higher in group A1. Endometrial thickness and V(max) were significantly increased in group B1 as compared to B2. The study indicates that latent tuberculosis should be considered in young Indian patients presenting with unexplained infertility with apparently normal pelvic and non-endometrial tubal factors and repeated IVF failure.

Abstract
OBJECTIVE To find whether plasma and follicular prorenin concentrations have any effect on the uterine arterial blood flow in women with polycystic ovarian syndrome (PCOS) compared to those with normal menstrual cycles (NMC). STUDY DESIGN Controlled prospective clinical study involved 55 women undergoing in vitro fertilization: 24 with PCOS and 31 with NMC. In both groups transvaginal colour Doppler assessment of uterine arterial blood flow was analysed on day 22 of the cycle, on the day of human chorionic gonadotrophin (HCG) administration and 36 h after HCG. Plasma and follicular (in the dominant follicle containing mature oocyte, and in the pooled follicles) prorenin and active renin, and serum estradiol and androstenedione concentrations were measured at these time-points. The Student's t-test and Pearson correlation were used for the statistical analysis. RESULTS The resistance index (RI) in the NMC group decreased from 0.84+/-0.05 on the day of HCG to 0.78+/-0.08 36 h after HCG (P < 0.05); in the PCOS group the RI did not decrease. Follicular prorenin concentrations in the dominant follicle and in the pooled follicles were lower in the PCOS than in the NMC group (20,210+/-10,831 microU/l, 16,753+/-8634 microU/l versus 42,637+/-35,400 microU/l, 33,067+/-26,200 microU/l; P < 0.05). CONCLUSIONS Plasma prorenin concentrations do not affect vascular impedance to the uterine artery, but follicular prorenin do by newly formed low resistant vessels in the follicles.

Abstract
OBJECTIVES The purpose of this study is to determine if the effects of tubal sterilization (TS) by laparoscopy have any risk of a subsequent significant decrease in ovarian reserve and vascular support within the ovary by means of stromal artery Doppler study, and to compare the results with matched paired controls. DESIGN Between February 2002 and January 2005, 148 healthy volunteers were enrolled sequentially, 74 undergoing laparoscopic TS (study group) and 74 age-, parity-, body mass index-matched women were recruited as a control group. The main outcome measurements were blood levels of follicle-stimulating hormone (FSH), luteinizing hormone and E2, ovarian volume, number of antral follicles and Doppler study of ovarian stromal artery pulsatile index (PI) and maximum velocity (Vmax) on the third day of the cycle immediately before, and 1 and 12 months after the surgical intervention. RESULTS There were significant elevations in both serum FSH levels and PI values observed 1 month after TS, compared to the preoperative levels (p < .05), and also when compared to controls. However, there were no significant elevations at 12 months postoperation in both study and control groups. The other outcome measurements did not show any significant differences between the two groups. CONCLUSIONS Tubal sterilization by laparoscopic electrocoagulation does not cause any decrease in ovarian reserve or ovarian stromal blood supply, except an early postoperative increase in FSH and PI.

Abstract
PURPOSE OF REVIEW This review summarizes the current knowledge about ultrasound scanning values in monitoring the structural and functional changes of the uterus and ovaries during the menstrual cycle. RECENT FINDINGS The views that ovulation is more frequently right sided have been challenged, with recent data suggesting that ovulation occurs randomly. A 'follicular wave phenomenon', providing a new model for ovarian function during the menstrual cycle, has been described. Follicular development occurs in a wave-like fashion and women with two waves have earlier endometrial development due to earlier increase of the dominant follicle estrogen production. Myometrial contractions during menstrual cycle should be considered in the assessment of endometrial thickness. Uterine-ovarian arterial blood flow impedance is important in understanding the normal physiology of the menstrual cycle and may be of use in assisted conception protocols. SUMMARY At present, ultrasound scanning has an important role in noninvasive assessment of endometrial and ovarian cyclical changes and may be of particular importance in assisted conception procedures. Further work is likely to help in understanding its full diagnostic potential.

OBJECTIVE To use power Doppler ultrasound to assess the effect of endometriosis on intraendometrial and subendometrial blood flow during the menstrual cycle. DESIGN An observational prospective study. SETTING Academic teaching hospital. PATIENT(S) Thirty patients with histologically confirmed ovarian endometrioma and 15 control women. INTERVENTION(S) Power Doppler ultrasound examination during the menstrual cycle. MAIN OUTCOME MEASURE(S) Intraendometrial and subendometrial color signals assessed by power Doppler ultrasound. RESULT(S) A statistically significant higher proportion of endometrioma patients presented simultaneous intraendometrial and subendometrial color signals in the late secretory cycle phase compared with controls (40.0% vs. 6.7%). CONCLUSION(S) The higher endometrial perfusion in patients with ovarian endometrioma that is observed in the late secretory phase of the cycle, close to menstrual shedding, favors the hypothesis that women with endometriosis might have higher endometrial vascular activity, thus facilitating the implantation process of endometrial cells outside the uterus.

Abstract
In order To evaluate whether the parameters of spiral artery blood flow, as measured by transvaginal color Doppler, may be used to assess endometrium receptivity prior to embryo transfer (ET), a retrospective study of 94 infertile women who had undergone ART treatments with different outcomes (pregnant or nonpregnant) was done. Subendometrial blood flow was evaluated. The resistance index (RI), systolic/diastolic ratio (S/D) and pulsatility index (PI) were significantly lower in those who achieved pregnancy as compared with those who did not: 0.62+/-0.04 vs 0.68+/-0.04 (P<0.001), 2.66+/-0.33 vs 3.19+/-0.39 (P<0.01) and 1.15+/-0.17 vs 1.34+/-0.22 (P<0. 05), respectively. Furthermore, when RI>0. 2, PI>1. , and S/D>3. , no pregnancy occurred. These data suggest that the parameters of spiral artery blood flow could be used as a new assay in predicting endometrial receptivity before ET.

Abstract
OBJECTIVES To examine the changes caused by tubal sterilization (TS) in ovarian hormone secretion and uterine and ovarian circulation. DESIGN Tubal sterilization was performed by minilaparotomy and laparoscopy methods in 36 women. Blood samples were taken for hormonal tests on Preoperative Day 3 (D3) of the menstrual cycle, on Postoperative Days 13-15 (periovulatory period) of the same cycle and on D3 in the 1st and 6th months post-TS. Uterine and ovarian artery blood flow rates of the women were measured on the same days as hormonal tests by transvaginal color Doppler ultrasonography (TVCDUSG). The control group was composed of 15 volunteers in the same age group who preferred the barrier method and who had the same TVCDUSG and hormonal analyses in the same periods. RESULTS There was a decrease in the uterine and ovarian artery pulsatility index (PI) measurements and an increase in serum luteinizing hormone (LH) and estradiol (E2) values during the periovulatory period as compared with preoperative and postoperative menstrual measurements in all groups. There was no difference between baseline uterine and ovarian artery PI and serum follicle-stimulating hormone, LH and E2 values and those measured on D3 of the menstrual cycle in the 1st and 6th months post-TS. CONCLUSIONS The 6-month postoperative follow-up of groups that had undergone different TS methods showed no difference in uterine or ovarian artery blood flow rates or ovarian hormone secretion in comparison with baseline values.

Abstract
BACKGROUND We used three-dimensional power Doppler angiography (3D-PDA) to examine the periodic changes in endometrial development and subendometrial vascularity during the normal menstrual cycle in 29 women with unexplained subfertility and 19 controls. METHODS 3D-PDA was performed on alternate days from day 3 of the cycle until ovulation and then every 4 days until menses. VOCAL (Virtual Organ Computer-aided AnaLysis) and shell-imaging were used to define and to quantify the power Doppler signal within the endometrial and subendometrial regions producing indices of their relative vascularity. RESULTS Women with unexplained subfertility demonstrated significant changes with time (P<0.001) in the indices of vascularity within the endometrium and subendometrium during the menstrual cycle characterized by a pre-ovulatory peak and post-ovulatory fall. These changes mirrored those observed in the control group but were significantly reduced in the endometrium and subendometrium during the mid-late follicular phase and early luteal phase. There were no differences in endometrial thickness or volume between the groups or in the plasma concentrations of estradiol or progesterone. CONCLUSIONS Endometrial and subendometrial vascularity are significantly reduced in women with unexplained subfertility during the mid-late follicular phase irrespective of estradiol or progesterone concentrations and endometrial morphometry.

Abstract
OBJECTIVE To characterize endometrial development in unexplained and tubal factor infertility. DESIGN Prospective study of 20 women with unexplained infertility, 22 with tubal factor infertility, and 21 fertile controls in the midproliferative, periovulatory, and midluteal phases of the menstrual cycle. SETTING Reproductive Medicine Department of St. Mary's Hospital, Manchester, United Kingdom. PATIENT(S) Women awaiting assisted conception. INVESTIGATION(S) Serum hormone assays, transvaginal ultrasound, Doppler, and midluteal endometrial biopsies. MAIN OUTCOME MEASURE(S) Serum levels of E2, P, and LH, endometrial ultrasound morphometry, uterine and subendometrial artery Doppler, and endometrial histology and biochemistry. RESULT(S) Women with unexplained infertility demonstrated significantly reduced uterine artery flow velocity in all phases, significantly elevated uterine and subendometrial artery impedance in the periovulatory and midluteal phases, and significantly reduced endometrial texture in the midproliferative phase. Women with tubal factor infertility demonstrated significantly reduced uterine artery flow velocity, without a concomitant increase in impedance, and significantly greater expression of endometrial glandular and luminal keratan sulphate. CONCLUSION(S) Unexplained infertility is associated with a profound impairment of endometrial perfusion that might be amenable to treatment by perfusion enhancers. Tubal factor infertility is associated with endometrial developmental defects that might be corrected by salpingectomy. Endometrial ultrasound and Doppler studies are likely to become a vital tool in the investigation of infertility.

Abstract
Background, Aims and Methods: Clomiphene citrate (CC) has been widely used for induction of ovulation; however, despite the high rate of ovulation, the pregnancy rate is only 30%. The anti-estrogenic effect of CC on the endometrium is one explanation for this finding. It is well known that repeated administration of CC enhances its anti-estrogenic effect. To overcome this adverse affect, a number of techniques have been used. One technique is the early administration of CC, in an attempt to decrease the anti-estrogenic effects of CC on the endometrium. The aim of the present study was to retrospectively evaluate if repeated administration of CC at varying times may affect the endometrium during preovulatory period; pregnancy rates were compiled for patients with unexplained infertility undergoing intrauterine insemination (IUI). The patients were divided into four groups based on the number of repeat administrations and the time of CC administration. Results: The endometrial thickness at the day of human chorionic gonadotropin administration was greater in early administration within three consecutive CC cycles than the others. Conclusion: When the endometrium is thin during classical administration of CC, it is worth attempting the early administration of CC in the CC/IUI treatment for patients with unexplained infertility. However, this effect disappeared over the duration of the three consecutive CC cycles. (Reprod Med Biol 2004; 3: 153-157).

Abstract
OBJECTIVE To evaluate the effect of adjuvant low-dose aspirin on utero-ovarian blood flow and ovarian responsiveness in poor responders undergoing IVF. DESIGN Prospective randomized, double-blind, placebo-controlled study. SETTING University-affiliated teaching hospital. PATIENT(S) Sixty patients classified as poor responders undergoing IVF. INTERVENTION(S) Supplementation with low-dose aspirin (80 mg daily) or placebo to a long down-regulation protocol. MAIN OUTCOME MEASURE(S) Doppler measurement of intraovarian and uterine pulsatility index was performed before (baseline) and after ovarian stimulation (day of hCG administration). Duration of use and dose of gonadotropins, cycle cancellation rate, number of mature follicles recruited, and oocytes retrieved were also measured. RESULT(S) High cancellation rates were found in both groups (33.3% vs. 26.7%, placebo vs. treatment). There were no significant differences in total dose of hMG used (66 vs. 57 hMG, 75 IU ampules), median number of mature follicles recruited (3.5 vs. 3.0), or median number of oocytes retrieved (4 vs. 3). No significant differences were found in either intraovarian or uterine artery pulsatility index measured at baseline or on the day of hCG administration. CONCLUSION(S) Supplementation with low-dose aspirin failed to improve either ovarian and uterine blood flow or ovarian responsiveness in poor responders undergoing IVF.

Abstract
OBJECTIVE To investigate the relationship between color Doppler indices of dominant follicular blood flow and clinical factors in in vitro fertilization-embryo transfer cycles. SUBJECTS AND METHODS This was a prospective study involving 26 patients completing a total of 33 in vitro fertilization cycles. Dominant follicular blood flow indices, peak systolic velocities, the resistance index and the pulsatility index were evaluated using transvaginal color Doppler. The indices were compared to the clinical outcomes of in vitro fertilization-embryo transfer. RESULTS There was a significant correlation between dominant follicular peak systolic velocities and the number of oocytes retrieved, as well as the number of mature oocytes obtained. There was no significant correlation between dominant follicular resistance index or pulsatility index and the number of follicles > 10 mm in diameter, the number of oocytes retrieved or the number of mature oocytes. There were no significant differences between dominant follicular peak systolic velocities, resistance index or pulsatility index, and fertilization rate or the ratio of good quality embryos. However, significant differences were found between the number of oocytes retrieved, as well as the number of mature oocytes for those patients in which the peak systolic velocity was below 25 cm/s. CONCLUSIONS Doppler assessment of dominant follicle blood flow alone is useful for predicting the number of retrievable oocytes. However, morphological quality of the embryo produced or the pregnancy rate cannot be predicted by this method.

Abstract
OBJECTIVE To evaluate whether, by blocking androgen action, flutamide can decrease and normalize vascular resistance in the uterine artery in patients with polycystic ovary syndrome (PCOS). DESIGN Prospective and controlled study. SETTING Endocrinological Centre of the Department of Obstetrics and Gynecology of the University of Cagliari, Italy. PATIENT(S) Twenty-two patients with PCOS were enrolled in the study and randomly assigned to one of the following two treatments for 3 months: oral administration of flutamide (250 mg twice daily) or placebo. INTERVENTION(S) Doppler flow measurement of the uterine artery and serum hormone concentration determination during the early follicular phase of the menstrual cycle before treatment and during the third month of treatment. MAIN OUTCOME MEASURE(S) Pulsatility index (PI) of the uterine artery before and during treatment. RESULT(S) The PI of the uterine artery decreased significantly during treatment. No difference was found in patients treated with placebo. Correlation was found only between the PI values of the uterine artery and DHEAS. CONCLUSION(S) The low uterine perfusion that characterizes patients with PCOS can be improved by the antiandrogenic effect of flutamide.

Abstract
PURPOSE Our purpose was to verify whether the blood flow impedance of the ovarian stromal artery in transvaginal color Doppler ultrasonography can predict the in vitro fertilization and embryo transfer (IVF-ET) outcomes. METHODS Transvaginal color Doppler ultrasonographic examinations were performed in 99 patients undergoing controlled ovarian hyperstimulation (COH) for IVF-ET. The pulsatility index (PI) was evaluated in the bilateral ovarian stromal arteries on the starting day of COH (PI1) and the day of hCG administration (PI2). The patients were classified into three groups by the mean PI1, PI2, and API (PI1 - PI2), respectively, and the IVF-ET outcomes were analyzed and compared. RESULTS There were no significant differences in the duration of COH, the total dosage of gonadotropins used for COH, the serum E2 concentration on day of hCG administration, the number of follicles on the day of hCG administration, the number of oocytes retrieved or fertilized in vitro, and the number of embryos transferred between their respective PI1, PI2, and API values. However, the pregnancy rate was significantly lower in the higher PI1 and PI2 groups than in the lower groups (p < 0.05, p < 0.05). Significant positive correlations were also found between PI1 and PI2 and the total dosage of gonadotropins for COH (Y= 0.483X + 27.1, r = 0.052, p < 0.05; Y = 0.877X + 26.6, r = 0.075, p < 0.05). CONCLUSIONS Our results showed that the lower PI in the ovarian stromal artery during COH is associated with the higher the pregnancy rate and the smaller amount of gonadotropins used for effective COH. This study suggests that the color Doppler ultrasonographic index (PI) of the ovarian stromal artery during COH may be useful for predicting the success of IVF-ET in infertile patients.

Abstract
OBJECTIVE To evaluate arterial and venous intraovarian blood flow in follicle stimulating hormone-stimulated cycles. SUBJECTS AND METHODS This was a prospective study of 76 follicle stimulating hormone-stimulated cycles carried out in 39 infertile patients who were included in a timed intercourse or intrauterine insemination program in a referral center for assisted reproduction. Transvaginal color and pulsed Doppler measurements of the follicular and luteal phase resistance index, pulsatility index, peak systolic velocity and maximum venous velocity were made and serum progesterone levels during the mid-luteal phase were recorded. Velocimetric parameters were established and then used to classify ovarian function as having a normal ovulatory cycle, or a cycle in which there was either luteal phase deficiency or a luteinized unruptured follicle. RESULTS In 52 normal ovulatory cycles, the luteal phase peak systolic and maximum venous velocities were significantly higher and resistance and pulsatility indices were significantly lower than those found in the follicular phase. In 15 women with luteal phase deficiency we did not find any differences in arterial velocimetric parameters when compared with normal ovulatory cycles. However, luteal phase maximum venous velocities were lower in the luteal phase deficiency cycles and there was a significant correlation between luteal phase maximum venous velocity and serum progesterone levels (r = 0.36). Luteinized unruptured follicle cycles (n = 9) did not show significant changes during the ovarian cycle and no 'luteal conversion' of the Doppler signal was identified. CONCLUSIONS Follicle stimulating hormone-stimulated cycles in infertile patients can have a high percentage of abnormal functional responses that can be diagnosed only by sonographic assessment, Doppler and the appropriate hormonal follow-up. Arterial and venous intraovarian blood flow remain unaltered during luteinized unruptured follicle cycles and serum progesterone levels correlated with luteal phase maximum venous velocity, which makes Doppler a potentially useful non-invasive test to assess ovulation and luteal function.

Abstract
The purpose of this review article was to analyze the literature on the prevalence, diagnosis and treatment of the congenital uterine anomalies and to discuss current dilemmas on their influence on reproductive outcome. Congenital uterine anomalies are commonly associated with repeated pregnancy failure, in particular an increased risk of first- and second-trimester miscarriages and preterm delivery. Recent reports on two-dimensional and three-dimensional transvaginal ultrasound and saline contrast sonohysterography appear promising for diagnosis and classification of congenital uterine anomalies. The ability to visualize both the uterine cavity and the fundal uterine contour on a three-dimensional scan facilitates the diagnosis of uterine anomalies and enables differentiation between septate and bicornuate uteri. Color Doppler ultrasound allows visualization of intraseptal vascularity and may help in distinguishing the avascular from the vascular septum. Less connective tissue in the septum may result in poor decidualization and placentation, while an increased amount of muscle tissue in the septum can cause miscarriage by the production of local uncoordinated myometrial contractility. Hysteroscopic septum excision is an effective procedure which improves live-birth rates. Because of its simplicity, minimal invasiveness, low morbidity and low cost, a more liberal approach to the treatment of uterine anomalies is being advocated.

Abstract
OBJECTIVE To evaluate whether the Doppler velocimetry of uterine and ovarian arteries during the periovulatory period in conception cycles differs from that in nonconception cycles. DESIGN Transvaginal color Doppler sonography was used to assess uterine and ovarian perfusion in 63 infertile women during the periovulatory period. RESULTS In the conception cycles (n = 16), the PI values of uterine arteries at the day of ovulation were significantly less than those in nonconception cycles (n = 47). There were no significant differences in the PI values of ovarian arteries between the conception and nonconception cycles. CONCLUSIONS In the present study, the conception cycles showed lower vascular impedance in the uterine during the periovulatory period than did the nonconception cycles. This endometrial perfusion presents an accurate noninvasive assay of uterine receptivity that can be used to predict the successful outcome of implantation and to reveal unexplained infertility problems.

Abstract
OBJECTIVE To compare the pulsatility index (PI) and resistance index (RI) at different sampling sites of the uterine and spiral arteries in the early and mid-menstrual phases. MATERIALS AND METHODS The uterine and spiral arteries of 110 women undergoing similar ovarian hyperstimulation and intra-uterine insemination regimes were examined using transvaginal color Doppler ultrasound. The uterine artery was sampled at five sites: (1) ascending branch; (2) descending branch; (3) proximal, near branch division; (4) mid, 0.5 cm distal to the division; (5) lateral location, 1 cm distal to the division. The spiral artery was sampled at three sites: (a) anterior; (b) fundal; (c) posterior. The uterine and spiral arteries were examined twice, on days 2-3 and 14-16, respectively, of the menstrual cycle. The women were also grouped according to age at examination, < or = 30 years and > 30 years. The PI and RI values for different sites, menstrual phase, and age were compared. RESULTS The mean PI and RI values of the uterine artery were: (1) 2.86 +/- 1.20 and 0.92 +/- 0.13; (2) 2.66 +/- 1.15 and 0.89 +/- 0.12; (3) 2.88 +/- 1.26 and 0.90 +/- 0.15; (4) 3.03 +/- 1.02 and 0.91 +/- 0.07; (5) 3.23 +/- 1.38 and 0.89 +/- 0.12; and of the spiral artery were (a) 1.61 +/- 1.01 and 0.69 +/- 0.17; (b) 1.69 +/- 0.74 and 0.74 +/- 0.17; (c) 1.73 +/- 0.86 and 0.68 +/- 0.17. The PI values for uterine and spiral arteries at two phases of the menstrual cycle were 2.92 +/- 1.18 and 1.55 +/- 0.72 (days 2-3); 3.11 +/- 1.15 and 1.80 +/- 1.02 (days 14-16), respectively; for younger women (age < or = 30 years) these values were 2.83 +/- 1.22 and 1.6 +/- 0.85 and for older women (age > 30 years) 3.0 +/- 1.34 and 1.72 +/- 0.96, respectively. CONCLUSIONS There were no significant differences in PI and RI values of the uterine and spiral arteries at different sampling sites, phase of the menstrual cycle or age. The higher PI values tended to occur in the lateral uterine artery and posterior spiral artery, during the mid-menstrual phase and in the older age group. The PI and RI values of the mid-uterine and fundal spiral artery sampling sites are representative of the whole uterine artery and spiral artery, respectively.

Abstract
Peak systolic velocity (PSV) of individual follicles has been correlated with oocyte recovery, fertilization rate and embryo quality [in women undergoing in-vitro fertilization (IVF) and embryo transfer]. The present study assessed the role of quantitative and qualitative indices of follicular vascularity in predicting pregnancy after IVF and embryo transfer. A total of 106 women undergoing IVF treatment for infertility who were considered to be at risk of failure (>37 years of age, history of low response to gonadotrophin stimulation, or multiple failed IVF cycles) constituted the study group. PSV was measured from the three largest follicles on both the right and left ovaries on the day of human chorionic gonadotrophin (HCG) administration using an Acuson Sequoia with a 4-8 MHz transvaginal probe. The quality of follicular flow was graded from 1 to 4 according to the amount of visible colour flow around the follicle (grade 1 when one-quarter of the follicle, grade 2 when one-half, grade 3 when three-quarters, and grade 4 when the entire follicle was surrounded by colour). Clinical pregnancies resulted in 11 (10%) of the 106 high-risk women. Women who had PSV >/= 10 cm/s in at least one follicle on the day of HCG administration more often became pregnant than those with PSV <10 cm/s (P = 0.05). All pregnancies occurred in women with grade 3 or 4 follicular blood flow. Qualitative as well as quantitative measurements of follicular flow predict pregnancy after IVF and embryo transfer.

Abstract
OBJECTIVE To investigate whether the timing of administration of clomiphene citrate (CC) affects hormone levels, follicular recruitment, reproductive end organs, and pregnancy rates. DESIGN Prospective, randomized, double-blind trial. SETTING Academic center. PATIENT(S) Twenty-three patients with unexplained infertility. INTERVENTION(S) Twenty-three patients with unexplained infertility underwent 45 cycles of CC and IUI. For each cycle, patients were randomized either to receive 100 mg of CC on days 1-5 and placebo on days 5-9 (study group), or placebo on days 1-5 and CC on days 5-9 (control group). MAIN OUTCOME MEASURE(S) The difference in uterine artery PI, number of follicles, endometrial thickness, and pregnancy rates. RESULT(S) Gonadotropins and E2 levels, as well as uterine artery pulsatility index, were significantly higher in the study group on day 5. In addition, in the study group, a longer time interval existed between finishing CC and IUI (8 versus 6 days; MD = 2 days; 95% CI = 1-3) and the pregnancy rate was higher than in the control group (6 versus 0; OR = 15.1; 95% CI = 1.1-72.4). CONCLUSION(S) Clomiphene citrate commenced on day 1 of the menstrual cycle, rather than day 5, results in more rapid follicular growth, a longer CC-free period before IUI, and higher pregnancy rates. Although methodologically sound, our results should be taken with some degree of caution because they are based on a relatively small number of patients.

Abstract
OBJECTIVE To confirm whether patients with polycystic ovary syndrome (PCOS) have a reduction in uterine perfusion and to verify whether chronic administration of cabergoline can decrease this high vascular resistance. DESIGN Prospective randomized trial. SETTING Endocrinological Centre of the Department of Obstetrics and Gynecology, University of Cagliari, Cagliari, Italy. PATIENT(S) Thirty patients were enrolled in the study: 20 affected by PCOS and 10 healthy controls. Patients with PCOS were randomly assigned to one of two treatments for 3 months: oral administration of cabergoline (0.5 mg) every week or oral administration of placebo every week. INTERVENTION(S) All patients underwent transvaginal ultrasonography associated with Doppler flow measurement of the uterine artery, and serum hormone concentrations were determined during the early follicular phase. In women with PCOS, Doppler flow measurement and hormonal assessment were repeated in the early follicular phase of the third month of treatment. MAIN OUTCOME MEASURE(S) Pulsatility index of the uterine artery before and during treatment. RESULT(S) The mean pulsatility index of the uterine artery in patients with PCOS was significantly higher than that of the control group (3.29+/-0.5 and 2.01+/-0.2, respectively). Patients with PCOS treated with cabergoline showed a significant increase in uterine perfusion, with a pulsatility index of 3.14+/-0.6 before and 2.39+/-0.5 during the treatment. No difference was found in patients with PCOS treated with placebo. CONCLUSION(S) Patients with PCOS have high resistance in the uterine arteries, but chronic administration of cabergoline can increase uterine perfusion.

Abstract
Pulsed arterial spin labeling was used for mapping ovarian perfusion and measurement of blood velocity in the ovarian artery. Arterial blood was tagged upstream by pulsed slice selective saturation, and saturation transfer due to perfusion was monitored within the rat ovary. The velocity of arterial blood was determined from the dependence of the saturation transfer on the thickness of the saturation slice and the delay between successive saturation pulses. This method allows for determination of arterial velocity, even when the artery itself is not identified in the images. The arterial velocity of blood to the ovary was 3.6+/-0.6 cm x s(-1). The mean ovarian perfusion was 8.7+/-3.5 ml x min(-1) x g(-1) during the surge of luteinizing hormone and 5.9+/-3.0 ml min(-1) x g(-1) during the luteal phase. Arterial labeling can thus be used for following vascular remodeling and angiogenesis during the ovarian cycle by MRI.

Abstract
Color Doppler ultrasound was used transrectally in 6 mares to locate both the left and right Aa. uterinae and to obtain flow velocity waveforms at defined times (Days 0, 5, 10, 15 and 20) during 4 estrous cycles. Blood flow reflected by the resistance index (RI) was determined for both arteries on 120 occasions. As there was no significant difference and a high correlation in the RI values between the left and right arteries (paired Student's t-test, correlation coefficient r > 0.94; P < 0.05), the average RI value was used for subsequent analyses. There were correlations between RI values, mares and day of estrous cycle (P < 0.0001). The mean RI was higher (P < 0.05) in the 2 multiparous mares (age, 12 to 13 yr) than in the 4 younger maiden mares (age, 6 to 10 yr). During the estrous cycle mean RI values on Day 0 (day of ovulation) and Day 10 were higher (P < 0.05) than on Days 5, 15 and 20, whereas between estrous cycles within mares no differences (P > 0.05) could be measured. The results suggest that transrectal Color Doppler sonography is a noninvasive method for examining differences in impedance to uterine blood flow between different mares and cycle periods.

Abstract
Objective: To review and sum up the published literature on gynecological Doppler ultrasound examination. Methods: Publications on gynecological Doppler ultrasound examination already known by the author, publications found in the bibliographic database Medline, and publications found in the reference lists of available studies were read, and relevant information was extracted and summarized. Results: Reference data representative of normal findings at transvaginal color and spectral Doppler ultrasound examination of the uterine and ovarian arteries have been established in healthy pre- and post-menopausal women and in normal early pregnancies. Blood flow velocities in the uterine and ovarian arteries change during the normal menstrual cycle and are very different in pre- and post-menopausal women. Lower blood flow velocities and higher pulsatility index (PI) values have been recorded in the ovarian arteries after the menopause. Uterine artery blood flow velocities increase and uterine artery PI values and resistance index (RI) values decrease with gestational age in the first trimester. There is not yet an established role of the gynecological Doppler ultrasound examination in clinical practice. It remains unclear whether the gynecological Doppler ultrasound examination contributes substantially to the clinical management of early pregnancy complications or infertility problems, to the differential diagnosis of pelvic masses or uterine pathology. Conclusions: Large prospective studies-preferably randomized controled trials-are needed to determine the clinical value of the gynecological Doppler ultrasound examination.

Abstract
OBJECTIVE To evaluate intraovarian resistance index (RI) in 47 healthy fertile volunteers with ovulatory cycles, 28 patients with luteal phase defect (LPD) and four patients with luteinized unruptured follicle (LUF Sy). STUDY DESIGN Transvaginal color Doppler assessment of the follicular and corpus luteum blood flow and plasma progesterone (P) levels were obtained in each patient. RESULTS Significantly higher intraovarian artery RI (< 0.001) was obtained for LPD group than for controls during the luteal phase. In the control group both follicular and corpus luteum RI were significantly lower (P < 0.001) on the dominant side, while in LPD group no difference (P > 0.05) between the sides occurred. Mean P levels were significantly lower (P < 0.001) in the LPD group (6.9 +/- 2.3 ng/ml) than in controls (24.1 +/- 11.4 ng/ml). In all the LPD patients histopathology revealed delayed endometrial pattern, while normal endometrial dating was found in all the evaluated patients form the control group (n = 15). In the patients with LUF Sy (n = 4) similar RI values were obtained in the follicular and corpus luteum phase. There was no difference between the sides in terms of the intraovarian RI, while subnormal values of P were obtained in all the examined patients (14.1 +/- 6.2 ng/ml). CONCLUSIONS Transvaginal color Doppler may predict the function capacity of the corpus luteum.
