Abstract
BACKGROUND Premature ovarian insufficiency (POI) is a clinical syndrome resulting from loss of ovarian function before the age of 40. It is a state of hypergonadotropic hypogonadism, characterised by amenorrhoea or oligomenorrhoea, with low ovarian sex hormones (oestrogen deficiency) and elevated pituitary gonadotrophins. POI with primary amenorrhoea may occur as a result of chromosomal and genetic abnormalities, such as Turner syndrome, Fragile X, or autosomal gene defects; secondary amenorrhoea may be iatrogenic after the surgical removal of the ovaries, radiotherapy, or chemotherapy. Other causes include autoimmune diseases, viral infections, and environmental factors; in most cases, POI is idiopathic. Appropriate replacement of sex hormones in women with POI may facilitate the achievement of near normal uterine development. However, the optimal effective hormone therapy (HT) regimen to maximise the reproductive potential for women with POI remains unclear. OBJECTIVES To investigate the effectiveness and safety of different hormonal regimens on uterine and endometrial development in women with POI. SEARCH METHODS We searched the Cochrane Gynaecology and Fertility (CGF) Group trials register, CENTRAL, MEDLINE, Embase, PsycINFO, CINAHL, and two trials registers in September 2021. We also checked references of included studies, and contacted study authors to identify additional studies. SELECTION CRITERIA We included randomised controlled trials (RCTs) investigating the effect of various hormonal preparations on the uterine development of women diagnosed with POI. DATA COLLECTION AND ANALYSIS We used standard methodological procedures recommended by Cochrane. The primary review outcome was uterine volume; secondary outcomes were endometrial thickness, endometrial histology, uterine perfusion, reproductive outcomes, and any reported adverse events. MAIN RESULTS We included three studies (52 participants analysed in total) investigating the role of various hormonal preparations in three different contexts, which deemed meta-analysis unfeasible. We found very low-certainty evidence; the main limitation was very serious imprecision due to small sample size. Conjugated oral oestrogens versus transdermal 17ß-oestradiol We are uncertain of the effect of conjugated oral oestrogens compared to transdermal 17ß-oestradiol (mean difference (MD) -18.2 (mL), 95% confidence interval (CI) -23.18 to -13.22; 1 RCT, N = 12; very low-certainty evidence) on uterine volume, measured after 12 months of treatment. The study reported no other relevant outcomes (including adverse events). Low versus high 17ß-oestradiol dose We are uncertain of the effect of a lower dose of 17ß-oestradiol compared to a higher dose of 17ß-oestradiol on uterine volume after three or five years of treatment, or adverse events (1 RCT, N = 20; very low-certainty evidence). The study reported no other relevant outcomes. Oral versus vaginal administration of oestradiol and dydrogesterone We are uncertain of the effect of an oral or vaginal administration route on uterine volume and endometrial thickness after 14 or 21 days of administration (1 RCT, N = 20; very low-certainty evidence). The study reported no other relevant outcomes (including adverse events). AUTHORS' CONCLUSIONS No clear conclusions can be drawn in this systematic review, due to the very low-certainty of the evidence. There is a need for pragmatic, well designed, randomised controlled trials, with adequate power to detect differences between various HT regimens on uterine growth, endometrial development, and pregnancy outcomes following the transfer of donated gametes or embryos in women diagnosed with POI.

Relationship between temporal changes of endometrial blood flow impedance during natural and hormone replacement cycles and prediction of pregnancy during vitrified-warmed embryo transfer. J Obstet Gynaecol Res 2021; 47:1052-1063.

Abstract
AIM This study aimed to examine the relationship between the temporal changes in endometrial blood flow impedance during natural and hormone replacement therapy (HRT) cycles and clinical outcomes of vitrified-warmed embryo transfer (ET). METHODS This retrospective observational cohort study included 60 women, 28 with natural, and 32 with HRT cycles, who underwent vitrified-warmed ET. Uterine radial artery resistance index (RA-RI) was measured during the natural and HRT cycles at the following time points: early follicular phase, day of the human chorionic gonadotropin injection during a natural cycle or day of progesterone administration during an HRT cycle, and day of ET. RESULTS The clinical pregnancy rates of the natural and HRT cycles were 32.1% and 34.4%, respectively. The RA-RI at the early follicular phase was significantly lower in the pregnant group than in the nonpregnant group with natural but not HRT cycles (p = 0.04). The odds ratio for pregnancy was 0.70 (95% confidence interval [CI], 0.52-0.95) when the RA-RI value at the early follicular phase was increased by 0.01 in the natural cycle. With the natural cycle, the area under the receiver-operating characteristic curves for the RA-RI at the early follicular phase with a threshold of 0.68 was 0.75 (95% CI, 0.57-0.93), and the positive and negative predictive values were 0.53 (95% CI, 0.37-0.59) and 0.92 (0.74-0.99), respectively. CONCLUSION RA-RI at the early follicular phase might be an effective and useful tool for deciding between natural or HRT cycles for vitrified-warmed ET.

Abstract
BACKGROUND Infertility is an important issue in women with Premature Ovarian Failure (POF). With no conclusive treatment available to enhance fertility in these women, it is the use of donor eggs with In-Vitro Fertilization (IVF) which can fulfil their desire to become a mother in a novel way. Hormone replacement therapy (HRT) in POF apart from correcting the endocrine defect also helps in improving the milieu of the uterus by improving its vascularisation and the sub endometrial blood flow. We thus aimed to carry out a study to find out whether hormone replacement therapy if administered prior to the oocyte donation cycle in patients of premature ovarian failure improves the pregnancy rate. METHODS A comparative study was carried out incorporating 46 subjects with 23 in each group. Group A received HRT prior to their oocyte donation cycle while the second group entered into the oocyte donation programme directly after an artificially induced menstruation. RESULTS It was observed that, although the HRT group had a slightly higher pregnancy rate, with a better mean endometrial thickness as compared to the non HRT group it was not statistically significant. CONCLUSIONS Institution of hormone replacement therapy does improve the vascularisation of the uterus, corrects the histologic features of the uterine lining and makes the endometrium receptive but whether it enhances the pregnancy rate needs to be elucidated with further studies.

Abstract
Normal gestation implants on a relatively hypoxic deciduas so that trophoblast deeply invades endometrium and angiogenesis seeks for oxygen supply. If implantation occurs before those hypoxic conditions occur, trophoblast invasion is defective, due to the relatively high oxygen tension in the decidual environment, laying the foundations for subsequent pre-eclampsia.

Abstract
BACKGROUND The endometrium becomes receptive to the embryo after sequential actions of estrogen and progesterone. The purpose of this study was to examine the effects of estrogen and progesterone on endometrial hemodynamics and on secretion of vascular endothelial growth factor (VEGF) from endometrial epithelial cells (EEC). METHODS Six early postmenopausal women taking sequential estrogen and progestin [days 1-11: estradiol valerate (estrogen) 2 mg daily; days 12-21: estradiol valerate 2 mg plus norethisterone acetate (progestin) 1 mg daily] were recruited. Three-dimensional power Doppler angiography (3D-PDA) was performed before hormone treatment (phase 0), on days 10-11 of hormone treatment (phase E), and on days 18-20 of hormone treatment (phase E + P). Ishikawa EEC were treated with or without 17-beta-estradiol and progesterone for 24 hours, followed by determination of VEGF concentrations in the supernatants. RESULTS The endometrial volume was significantly increased in phase E and phase E + P as compared with that in phase 0. The vascularization index, flow index, and vascularization flow index in the subendometrial region, as measured by 3D-PDA, were significantly higher in phase E + P than in phase 0, but there were no significant differences in these indices between phase 0 and phase E. While treatment of EEC with 17-beta-estradiol had little enhancing effect on VEGF production, progesterone alone or in combination with 17-beta-estradiol significantly increased VEGF secretion from EEC. CONCLUSION Our data suggested that progesterone could stimulate VEGF secretion from EEC and subsequently increase subendometrial vascularity and blood flow.

Abstract
OBJECTIVE To evaluate the predictive value of serial uterine artery Doppler ultrasound for embryo implantation in in-vitro fertilization (IVF)-intracytoplasmic sperm injection (ICSI) cycles. METHODS This was a prospective observational study at the VU University Medical Center, Amsterdam. Patients with an indication for IVF or IVF-ICSI according to departmental protocol underwent controlled ovarian hyperstimulation followed by IVF or IVF-ICSI and embryo transfer and had serial Doppler ultrasound performed during this treatment cycle. Patient and cycle characteristics, number of conceptions and ongoing pregnancies and pulsatility index (PI) of both uterine arteries on different cycle days were assessed and results were compared between patients who conceived and those who did not. RESULTS Of the 102 patients enrolled into the study, 83 underwent embryo transfer. Of these, 41 became pregnant and 42 did not (Group 1). Of the 41 pregnancies, 30 were ongoing (Group 2) and 11 miscarried (Group 3). Between Groups 1, 2 and 3, linear regression revealed no significant difference between any of the variables examined except in the quality of transferred embryos. There was no significant difference in the mean PI of the left and right uterine arteries on any day of the cycle, or in the change in PI during the cycle. Receiver-operating characteristics curves derived to determine the performance of PI to predict pregnancy outcome supported our findings that the uterine artery PI is not a suitable marker for identifying patients with implantation failure. Multivariate analysis showed no relationship between pregnancy and PI between groups, but it did show a relationship between pregnancy and some patient and cycle characteristics. CONCLUSION In an unselected group of patients undergoing IVF or IVF-ICSI and embryo transfer, serial Doppler ultrasound examination of the uterine artery does not discriminate between cycles resulting in ongoing pregnancy, miscarriage and no pregnancy.

Abstract
OBJECTIVE To determine the role of saline infusion sonography (SIS) in uterine evaluation before a frozen embryo transfer (FET) cycle. DESIGN Retrospective cohort analysis. SETTING University hospital. PATIENT(S) Thirty-six patients who had uterine evaluation by SIS before FET cycle. INTERVENTION(S) The SIS was performed in the follicular phase of the menstrual cycle before the actual FET cycle. MAIN OUTCOME MEASURE(S) The SIS findings, clinical pregnancy rate (PR), ongoing PR, and correlation between positive SIS findings with and without subsequent treatment and pregnancy outcome. RESULT(S) Positive SIS findings were found in 11/36 patients (30.5%), which included uterine septum (9.0%), endometrial polyp (45.4%), intramural fibroid with normal cavity (9.0%), cystic endometrial changes (9.0%), cervical stenosis (18.1%), and calcification with normal cavity (9.0%). The overall clinical PR in all groups was 51.4%, with an ongoing PR of 45.7%. Patients with positive SIS finding who underwent subsequent hysteroscopic correction (7/11) had a clinical PR of 85.7% as compared to 54.1% in patients with normal uterine cavity (24/35). Patients with positive SIS findings and no operative hysteroscopy (4/11) had a clinical PR of 50% and pregnancy loss rate of 100%. CONCLUSION(S) Obtaining an SIS before the FET cycle can be helpful in the detection of uterine abnormalities. If time since uterine evaluation has been more than 1-2 years, performing an SIS is recommended as subsequent correction of the anomalies may improve FET outcome.

Abstract
It is well known that an adequate endometrial receptivity is required for successful implantation in both natural and assisted reproductive cycles. In particular, a brief "implantation window", during which endometrium undergoes anatomical and molecular changes necessary for embryo implantation, has been observed. The hormonal treatment applied to induce ovulation seems to be able to modify the normal development of the prenidatory endometrium, with possible negative effect on the implantation rate. For this reason, several attempts have been made to identify specific markers of endometrial receptivity, useful for predicting implantation outcome in clinical practice. Even if different histological, immunohistochemical, and ultrasonographic parameters are studied, none unfortunately has been univocally shown to be predictive of pregnancy outcome. Therefore, the evaluation of endometrial receptivity remains a challenge in clinical practice.

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
The understanding and control of embryo implantation represents the major challenge for assisted reproductive technologies. Along with developments in basic research and efforts to optimize embryo quality, the improvement of noninvasive and reliable methods to assess uterine receptivity constitutes an important step toward meeting such a challenge. Today, ultrasound-based approaches to evaluate endometrial echogenicity and uterine perfusion and contractility are available for practical use. Increasing evidence indicates that echogenic patterns of the endometrium reflect histologic processes that are involved in the establishment of receptivity. This constitutes a possible explanation for the reported association between premature hyperechogenic patterns of the endometrium and poor implantation rates. Nevertheless, additional studies aiming at correlating further morpho-biochemical events in the endometrium with its echogenicity patterns are needed. Further, developments in vascular assessment by Doppler, Doppler-related, and vascular detection technologies will also be instrumental in monitoring and improving vascular changes that lead to uterine receptivity. Finally, data supporting the hypothesis that uterine contractility, as visualized by ultrasound, influences in vitro fertilization-embryo transfer (IVF-ET) pregnancy rates encourage further investigation on both the regulation and control of uterine contractions. This article discusses some of the advantages and limitations of ultrasonographic assessments of uterine receptivity in the perspective of the new millennium.

Abstract
OBJECTIVE To investigate the role of sonographic parameters in assessing endometrial receptivity in an in vitro fertilization (IVF) program. DESIGN Prospective clinical study. SETTING University setting. PATIENT(S) One hundred thirty-five patients in our IVF program, selected prospectively on the day of oocyte retrieval. INTERVENTION(S) Transvaginal ultrasound examination was performed before oocyte collection. MAIN OUTCOME MEASURE(S) Association between implantation rate and spiral artery blood flow (primary outcome measure) and between implantation rate and endometrial measurements as well as uterine artery blood flow (secondary outcome measures). RESULT(S) Overall implantation rate was 23.7% per cycle. Subendometrial blood flow was detected in 113 (83.7%) cases, with pregnancy occurring in 21.2%. Mean spiral artery pulsatility index values were 1.12 +/- 0.28 and 1.21 +/- 0.27 for nonconception and conception cycles, respectively. Nondetectable spiral artery blood flow was not associated with a lower implantation rate. Neither endometrial thickness nor endometrial volume was correlated with the likelihood of successful implantation. Minimum endometrial thickness and volume associated with pregnancy were 6.9 mm and 1.59 mL, respectively. CONCLUSION(S) Neither Doppler sonography of the spiral or uterine arteries nor measurement of the endometrial thickness or volume allowed a reliable prediction of subsequent IVF outcome.

Abstract
This study was designed to investigate the role of three-dimensional (3D) power Doppler sonography of the (sub-) endometrial area on the first day of ovarian stimulation in predicting the outcome of an in-vitro fertilization (IVF) programme. Among the 75 cycles analysed, the overall pregnancy rate was 20% (15/75) per cycle and 23.8% (15/63) per embryo transfer. Intra-observer variability of the colour histogram was checked in 14 patients with the results demonstrating a high level of agreement. Neither endometrial measurements nor uterine blood flow were correlated with the pregnancy rate. In contrast, all 3D indices were significantly lower in conception compared with non-conception cycles (P < 0.05). Logistic regression analysis found the subendometrial flow index to be the strongest predictive factor of IVF success among the tested sonographic parameters (P = 0.04). In conclusion, quantitative assessment of spiral artery blood flow may be of predictive value for implantation in IVF cycles even before ovarian stimulation therapy is started.

Abstract
OBJECTIVE To assess the effect of oral hormone replacement therapy (HRT) on body weight, insulin-like growth factor I (IGF-I), and GH response to exogenous GHRH [corrected] in women with premature ovarian failure (POF) [corrected]. DESIGN Controlled clinical study. SETTING Outpatients studied in the department of endocrinology of the University Hospital in Vienna. PATIENT(S) Twenty-four women with POF (study group) and 24 volunteers with normal ovarian cycles (control group). INTERVENTION(S) Pituitary GHRH [corrected] stimulation was performed in all women at study entry and in patients with POF after 1, 6, and 12 months of standard oral HRT. Blood samples were collected from 15 minutes before to 120 minutes after GHRH administration [corrected]. Body weight also was evaluated. RESULT(S) No differences in baseline and stimulated serum GH were found either between POF women and controls or in POF women during HRT. Women with POF without HRT had significantly higher IGF-I levels; a reduction in circulating IGF-I levels occurred during HRT. Body weight remained stable. CONCLUSION(S) Our results show the following: [1] Women with POF have similar Gh secretion patterns as healthy age-matched women; [2] physiologic HRT has no impact on GHRH-induced [corrected] GH stimulation; and [3] HRT has no impact on body weight in women with POF.

Abstract
Transvaginal color Doppler offers a closer look at blood flow within the reproductive organs. Recent literature using this technique demonstrates that 1) blood flow in the uterine and ovarian arteries is related inversely to estrogen levels, 2) no significant difference is seen between right and left uterine arteries among fertile and infertile patients, and 3) high resistance in uterine and ovarian arteries is correlated directly with poor pregnancy outcome. The question remains: Is there an resistive index or pulsatility index value, representing a cut-off point, for predicting successful outcome in the patient undergoing in vitro fertilization?

Abstract
OBJECTIVE To determine whether uterine vasculature is affected by age using oocyte donation as an in vivo model. DESIGN Prospective longitudinal study in which recipients were grouped according to age. They underwent a successful oocyte donation cycle, and single pregnancies were followed during the first trimester by color Doppler ultrasound in uterine arteries. SETTING Oocyte donation and IVF program at the Instituto Valenciano de Infertilidad. INTERVENTIONS Serum E2, P, and hCG levels in single ovum donation pregnancies; pulsatility and resistance indexes in uterine arteries during initial pregnancy. RESULTS Similar serum levels of E2, P, and hCG in both groups of patients were observed. There was no difference between groups regarding the flow indexes analyzed. CONCLUSIONS The increased incidence of early pregnancy losses observed in patients > 40 years cannot be attributed to defective response of uterine vasculature to exogenous hormone replacement. Thus, uterine aging does not appear to be a factor influencing the poor reproductive performance of women with advancing age.
