Abstract
PURPOSE Endometrial compaction (EC) is defined as the difference in endometrial thickness from the end of the follicular phase to the day of embryo transfer (ET). We aimed to determine the role of EC in predicting assisted reproductive technology (ART) success by conducting a meta-analysis of studies reporting the association between EC and clinical outcomes of ART. METHODS MEDLINE via PubMed, Web of Science, Scopus, and the Cochrane Central Register of Controlled Trials (CENTRAL) were searched from the date of inception to May 19, 2023. The primary outcome was live birth rate (LBR) per ET. Secondary outcomes were live birth or ongoing pregnancy per ET, ongoing pregnancy per ET, clinical pregnancy per ET, and miscarriage per clinical pregnancy. RESULTS Fifteen studies were included. When data from all studies reporting live birth were pooled, overall LBR rates were comparable in cycles showing EC or not [RR = 0.97, 95%CI = 0.92 to 1.02; 10 studies, 11,710 transfer cycles]. In a subgroup of studies that included euploid ET cycles, a similar LBR for patients with and without EC was noted [RR = 0.99, 95%CI = 0.86 to 1.13, 4 studies, 1172 cycles]. The miscarriage rate did not seem to be affected by the presence or absence of EC [RR = 1.06, 95%CI = 0.90 to 1.24; 12 studies]. CONCLUSION The predictive value of EC in determining LBR is limited, and assessment of EC may no longer be necessary, given these findings. TRIAL REGISTRATION PROSPERO CRD42023410389.

Abstract
We aimed to assess the effect of endometrial compaction on the live birth rate in frozen-thawed embryo transfer (FET) cycles and to investigate the parameters associated with compaction. FET cycles performed in a tertiary care infertility centre between May 2013 and October 2019 were reviewed retrospectively. The decremental change of endometrial thickness between the end of oestrogen phase and ET day was defined as endometrial compaction. The primary outcome measure was endometrial compaction, and the secondary outcome was the live birth rate. Among all, 89 had endometrial compaction and 194 did not. The live birth rate was significantly higher in the compaction group (23.6 vs. 13.4%, respectively; p = 0.039). Multivariate logistic regression analysis revealed that in FET cycles with artificial endometrial preparation, the chance for live birth was significantly higher in cycles with endometrial compaction [OR: 3.133, 95% confidence interval (CI) 1.104-8.892; p = 0.032] when adjusted for age, stage of the embryo, and endometrial thickness at the end of the oestrogen phase. According to receiver operating characteristic (ROC) curve analysis the sensitivity and specificity of 9.25 mm endometrial thickness at the end of oestrogen phase were 76.4 and 58.8%, respectively (area under the curve: 0.701, 95% CI 0.640-0.763; p < 0.001) to predict endometrial compaction.

Abstract
Objective: The aim of our study was to evaluate sonographic endometrial thickness succeeding the estrogen-only stage and on the
day when embryo transfer (ET) occurred in artificial frozen embryo transfer (FET) cycles to delve into the effect of endometrial
compaction (EC) on clinical pregnancy rate (CPR).
Patients and Methods: In the first group endometrial thickness diminished when ET occurred when compared to the end of the
estrogen-only phase (n:37). Endometrial thickness increased/did not alter for the second group (n:70).
Demographic characteristics were recorded and the following were studied: in vitro fertilization (IVF) treatment indications, hormone
levels, total antral follicle count, duration of infertility, embryo quality, embryo-fundus distance, endometrial thickness at the end of
estrogen-only phase and on ET day, luteal support, CPR.
Results: No significant difference occurred in CPRs (n:107). ET, on day 5 was higher in the first group (p

Endometrial compaction is associated with increased clinical and ongoing pregnancy rates in unstimulated natural cycle frozen embryo transfers: a prospective cohort study. J Assist Reprod Genet 2022; 39:1909-1916.

Abstract
PURPOSE To investigate the association between endometrial compaction and pregnancy rates in unstimulated natural cycle frozen embryo transfers. DESIGN A single-center prospective cohort study. Endometrial thickness by transvaginal ultrasound and blood progesterone levels on the day of ovulation and the day of embryo transfer were evaluated in patients undergoing natural cycle frozen embryo transfer. Compaction was defined as > 5% decrease in endometrial thickness between ovulation day and day of transfer. Clinical and ongoing pregnancy rates in cycles with and without compaction were compared. RESULTS Seventy-one women were included, of which 44% had endometrial compaction, with similar rates when subdividing the patients by day of transfer (day 3 or day 5). Clinical and ongoing pregnancy rates were higher in the compaction group compared to the non-compaction group (0.58 vs. 0.16, P < 0.001; 0.52 vs. 0.13, P < 0.001 respectively). Subdividing by degree of compaction > 10% and > 15% revealed similar pregnancy rates as > 5%, with no added benefit to higher degrees of compaction. CONCLUSIONS About half the patients in our study undergoing unstimulated natural cycle frozen embryo transfer experienced compaction of the endometrium, occurring as early as day 3 post-ovulation. This was significantly correlated with increased clinical and ongoing pregnancy rates.

Abstract
OBJECTIVE To evaluate whether endometrial thickness (EMT) change in response to progesterone has an effect on pregnancy outcomes in frozen-thawed embryo transfer (FET) cycles. DESIGN Retrospective observational study. SETTING Tertiary-care academic medical center. PARTICIPANTS 4465 infertile women undergoing their first FET between January 2010 and December 2015 in our center. METHODS This observational study included 4465 patients undergoing their first FET cycles between January 2010 and December 2015. EMT was measured by transvaginal ultrasound one day before progesterone administration and on the day of FET to observe EMT change. MAIN OUTCOME MEASURES Clinical pregnancy rate (CPR) and the live birthrate (LBR) was discussed. RESULTS Regardless of the endometrial preparation protocols such as artificial cycle, estrogen-progesterone replacement therapy (EP) or natural cycle (NC), EMT may increase, decrease or remain stable on the day of FET compared with that of one day before progesterone administration. CPR in EMT increase, decrease and stable groups were 48.4%, 51.3% and 50.7% in EP cycle versus 49.2%, 52.0% and 48.9% in NC cycle, showing no significant difference between the three groups in both cycles (P= 0.48, P= 0.49). LBR was 40.9%, 45.9% and 42.6% in EP cycle versus 44.2%, 44.8% and 42.1% in NC cycle, also showing no significant difference between the three groups in both cycles (P= 0.16, P= 0.66). In addition, CPR and LBR were not significantly associated with EMT increase. CONCLUDES EMT may increase, decrease or remain stable on the day of FET as compared with that of one day before progesterone administration. Whatever change in EMT that occurs after progesterone administration has no significant effect on CPR and LBR in FET cycles.

Abstract
OBJECTIVE To evaluate whether the change in endometrial thickness between the end of the estrogen phase and the day of embryo transfer has an impact on the pregnancy rate in frozen-thawed embryo transfer (FET) cycles. DESIGN Retrospective observational cohort study. SETTING Single tertiary care medical center. PATIENT(S) Ultrasound images in 274 FET cycles were reviewed. All patients underwent endometrial preparation with the use of hormonal therapy. INTERVENTIONS(S) Ultrasound measurements of endometrial thickness at the end of the estrogen phase and the day of embryo transfer. MAIN OUTCOME MEASURE(S) The change in endometrial thickness and ongoing pregnancy rate. RESULT(S) We calculated the ongoing pregnancy rate in patients whose endometrial thickness decreased (compacted) after starting progesterone by 5%, 10%, 15%, or 20% compared with patients with no change or increased endometrial thickness. The ongoing pregnancy rate was significantly increased at all levels of compaction compared with no compaction. The ongoing pregnancy rate showed a significant increase with each decreasing quartile of change in thickness (increased percentage of compaction) in the progesterone phase compared with the estrogen phase. CONCLUSION(S) There is a highly significant inverse correlation between the ongoing pregnancy rate and the change of endometrial thickness between the end of estrogen administration and the day of embryo transfer.

Abstract
BACKGROUND A detailed assessment of the uterus forms a pivotal part of the ART treatment process. The emergence of three-dimensional ultrasound (3D US) has provided clinicians with a highly powerful tool in this respect. Assessments with 3D US range from the reconstruction of anatomical planes elusive to conventional US, to the objective measurement of anatomical volumes and vascularization parameters. However, despite the ever increasing number of publications emerging in the literature, the question of which aspects of 3D US are of most clinical value remains a topic of debate. OBJECTIVE AND RATIONALE The objective of this review is to dissect which aspects of the 3D US assessment of the uterus are supported by a strong level of evidence to date, and should therefore be incorporated into current routine clinical practice. SEARCH METHODS We conducted a systematic search of the PubMed database up to May 2016, using a combination of text words and Medical Subject Headings (MeSH) pertaining to the 3D US assessment of the uterus. All articles published in the English language were screened to ascertain relevance to women of reproductive age; further citations were retrieved through manual reference list searching. OUTCOMES A multitude of predominantly observational studies were identified, which concerned a vast variety of 3D US uterine assessments. All articles unequivocally praised the non-invasive, cost-effective, highly acceptable and objective nature of 3D US. Studies regarding the value of assessing the endometrial volume and vascularization prior to embryo transfer appeared conflicting and inconsistent. Studies regarding the imaging of uterine pathology and identification of intratubal and intrauterine devices consistently reported high rates of diagnostic accuracy. A recent RCT did not show an improvement in clinical outcomes when comparing 3D versus 2D US during embryo transfer. However, preliminary studies suggested that 3D US is superior in determining the site of implantation, particularly in ambiguous cases such as interstitial and angular pregnancies. Finally, pilot studies have suggested that the further integration of 3D and possibly 4D US with surgical interventions of the uterus may be a promising prospect. WIDER IMPLICATIONS 3D US may prove to be an invaluable tool in the assessment of the uterus within the context of ART. Currently, the aim should be to highlight the aspects of 3D US that are most evidence-based and valuable for patients, and to incorporate these into routine clinical practice.

Abstract
Ultrasound (US) is very useful in diagnosing causes of infertility. Pelvic masses, mullerian anomalies, ovarian reserve, and tubal patency can all be assessed using ultrasonographic techniques. US has also proven to be a very useful aid in managing infertility treatments. In this chapter, we review the uses of US in monitoring follicular development, assessing the endometrium during treatment, and as an aid to embryo transfer during in vitro fertilization.

Abstract
Endometrial receptivity plays a crucial role in the establishment of a healthy pregnancy in cycles of assisted reproduction. The endometrium as a key factor during reproduction can be assessed in multiple ways, most commonly through transvaginal grey-scale or 3-D ultrasound. It has been shown that controlled ovarian hyperstimulation has a great impact on the uterine lining, which leads to different study results for the predictive value of endometrial factors measured on different cycle days. There is no clear consensus on whether endometrial factors are appropriate to predict treatment outcome and if so, which one is suited best. The aim of this review is to summarize recent findings of studies about the influence of endometrial thickness, volume and pattern on IVF- and ICSI-treatment outcome and provide an overview of future developments in the field.

Abstract
OBJECTIVE To compare pregnancy rates with two different methods of intrauterine insemination (IUI) timing in patients treated with clomiphene citrate (CC). DESIGN Prospective, randomized trial. SETTING Academic medical center. PATIENT(S) One hundred fifty ovulatory, infertile women. INTERVENTION(S) Patients were randomized into a luteinizing hormone (LH) surge group or a follicle monitoring/human chorionic gonadotropin (hCG) group. All patients underwent baseline ultrasound, and took clomiphene citrate, during days 5-9. Patients in the LH surge group underwent IUI on the day after a home test for the LH surge was positive, whereas those in the hCG group received hCG according to ultrasound parameters and underwent insemination 33-40 hours later. Patients remained in the same study group for up to three cycles. MAIN OUTCOME MEASURE(S) Pregnancy rates per cycle and per patient. RESULT(S) No significant differences were found between groups in pregnancy rates per patient or per cycle. The LH surge group underwent IUI significantly later than the hCG group. Cancellation rates were significantly higher for the LH surge group (31% vs. 11%) and attributable mainly to failure to detect an LH surge. The majority of pregnancies in both treatment groups occurred in the first cycle. CONCLUSION(S) The decision to use hCG for IUI timing should be influenced by factors other than pregnancy rates.

Abstract
OBJECTIVE To compare the effectiveness of clomiphene citrate (CC) alone or combined with phytoestrogens (PE) in ovulation induction in patients who had intrauterine insemination in a randomized, double-blind study. METHODS A total of 134 women aged 25-35 years, who were infertile for at least 2 years and who had oligomenorrhea or amenorrhea associated with a positive menstrual response to the intramuscular progesterone-challenge test were enrolled. They were randomly treated with CC (100 mg daily for 5 days) and CC (100 mg daily for 5 days) in combination with PE (1500 mg daily for 10 days). We estimated the difference in uterine artery pulsatily index, number of preovulatory follicles, endometrial thickness, and pregnancy rate. RESULTS Both treatments increased follicle-stimulating hormone, luteinizing hormone, and 17beta-estradiol plasma concentrations, but the differences were not statistically significant. However, the differences in endometrial thickness of the two groups were statistically significant. No significant differences in the pulsatility index values and in the number of preovulatory follicles were noted. CONCLUSION A high dose of phytoestrogens can reverse the deleterious effects of clomiphene citrate on endometrial thickness and could contribute to higher pregnancy rates.

Abstract
An optimal initial infertility investigation protocol would be a process that is diagnostically accurate, expeditious, cost-effective, reliable and as minimally invasive as possible. In addition, the investigation should provide the clinician with useful prognostic information regarding possible future treatment. At present, extensive use of invasive procedures such as diagnostic hysteroscopy and laparoscopy is the standard at many fertility centres. Recent advances in gynaecological ultrasonography have shown that ultrasound can replace routine invasive investigative procedures. An ultrasound-based approach would make the basic infertility investigation less time-consuming and less expensive, but at the same time more acceptable to the majority of patients. This chapter describes an ultrasound-based approach to the assessment of infertility. In addition, the role of ultrasonography for assessment of the pelvic organs as a basic part of the initial investigation of an infertile couple is discussed and compared to more traditional invasive methods.

Abstract
OBJECTIVES The aim of the present study was to investigate the relations of ultrasonographic endometrial thickness and uterine size to bone mineral density (BMD). METHODS Subjects were 200 postmenopausal women (mean age +/- S.D., 57.4 +/- 7.7 years; range, 46-75 years). Age, age at menopause, years since menopause (YSM), height, weight, and body mass index (BMI, weight/height2) were recorded. Endometrial thickness and uterine size (i.e. uterine volume and cross-sectional area) were measured by transvaginal ultrasonography. BMD of the nondominant forearm (one-tenth of the distance from the distal end of the radius) was measured by dual-energy X-ray absorptiometry. Relations of these variables to BMD were investigated. RESULTS BMD was inversely correlated with age and YSM (r = -0.69, P < 0.0001; r = -0.56, P < 0.001, respectively), while was positively correlated with uterine volume, uterine cross-sectional area, and endometrial thickness (r = 0.52, P < 0.001; r = 0.45, P < 0.01; r = 0.32, P < 0.05, respectively). After adjusting for age, YSM, and BMI, BMD was still correlated with uterine volume and uterine cross-section (P < 0.01 and 0.05, respectively), while correlation of endometrial thickness with BMD disappeared. CONCLUSION Ultrasonographic uterine size shows higher correlation with BMD than endometrial thickness in postmenopausal women. This may be attributable to the fact that uterine size rather than endometrial thickness reflects the duration of estrogen deficiency after menopause.

Abstract
OBJECTIVE The purpose of this study was to investigate the influence of body mass index and body composition on endometrial thickness and bone mass. STUDY DESIGN This was a cross-sectional study that included 531 healthy postmenopausal women aged 48 to 65 years. Endometrial thickness was measured as double-layer thickness. Body composition was measured by dual energy x-ray absorptiometry, which divides the body into fat mass, lean mass, and bone mass, both for the total body and regional body compartments. An abdominal region was inserted manually. Statistics were Pearson correlations and analysis of variance. RESULTS Endometrial thickness and total body bone mass were correlated, respectively, to body mass index (r = 0.14, P <.01; r = 0.35, P <.001), total body fat mass (r = 0.14, P <.01; r = 0.38, P <.001), abdominal fat mass (r = 0.16, P <.001; r = 0.33, P <.001), peripheral fat mass (r = 0.10, P <.05; r = 0.41, P <.001), and abdominal/peripheral fat mass (r = 0.12, P <.01; r = 0.11, P <.01). CONCLUSION High body mass index and abdominal fat distribution correlate with increased endometrial thickness and bone mass.

Abstract
OBJECTIVE To compare the effectiveness of clomiphene citrate used alone and in combination with ethinyl E2 for the induction of ovulation in patients undergoing IUI. DESIGN Randomized, double-blind study. SETTING Four infertility treatment centers. PATIENT(S) Women aged 25-35 years with infertility of at least 2 years' duration and oligomenorrhea or amenorrhea associated with a positive menstrual response to an IM progesterone challenge. INTERVENTION(S) A total of 64 patients were randomized to treatment with CC (100 mg daily for 5 days) or CC (100 mg daily for 5 days) plus ethinyl E2 (0.05 mg daily for 5 days). MAIN OUTCOME MEASURE(S) The uterine artery pulsatility index, number of preovulatory follicles, endometrial thickness, and pregnancy rate. RESULT(S) Both treatment regimens increased FSH, LH, and 17beta-E2 levels, with no statistically significant differences. There was a statistically significant difference in endometrial thickness between the two treatment groups. No statistically significant differences were noted in pulsatility index values or in the number of preovulatory follicles. CONCLUSION(S) Ethinyl E2 can reverse the deleterious effects of CC on endometrial thickness, which may contribute to higher pregnancy rates.

Abstract
PURPOSE Our purpose was to verify our earlier observation of an altered endometrial echo character during the periimplantation period, signifying the earliest detection of implantation by ultrasound. METHODS The transvaginal ultrasound study used a 7.5-MHz probe on day 6 following preembryo transfer. RESULTS Of 31 embryo transfers studied. 8 (25.8%) were positive for this sign on day 6, whereas 9 patients later showed a gestational sac, giving an accuracy of this sign of 88.8% (8 of 9). CONCLUSIONS The normal secretory-phase endometrium shows a typical, evenly distributed hyperechogenecity described earlier by Hackeloer (1). In some cases of proliferative phases, too, this echo pattern has been reported by others (2, 3), and observed by us in stimulated and unstimulated cycles, and has been named type A endometrium by Gonen et al. (4) Both these varieties are seen to have an even, unbroken outline at the anterior and posterior myometrial-endometrial interphase. We report what we believe to be the earliest ultrasound picture of implantation, resembling this variety of endometrial echo but having an irregular outline (Fig. 2).

Abstract
In 53 patients of an in vitro fertilization (IVF) program with unsuccessful fertilization of oocytes, an endometrial biopsy was carried out on the day of the intended embryo transfer. The results were compared with the thickness (assessed on the very same day by means of ultrasonography) and the echo pattern of the endometrium, which was classified into four grades (A to D). We found grade A in 16 cases (30%), grade B in 22 cases (41.5%) and grade C in 15 cases (28.5%); no endometrium was assessed as grade D. The distribution of histologic findings was not significantly skewed within the respective grading categories (only 37.5% of grade A endometria, 63.5% of grade B endometria and 66.5% of grade C endometria were in phase with the menses). The in-phase and out-of-phase endometria did not display significant differences in endometrial thickness (8.8 +/- 0.29 mm vs. 9.13 +/- 0.4mm). Neither the sonographically measured endometrial thickness nor the echo pattern correlated with the histologic findings, suggesting that ultrasonography is inadequate for drawing reliable conclusions about endometrial receptivity in an IVF program.

Abstract
Transvaginal sonography is useful for the identification of physiologic and pathologic changes within the myometrium and endometrium. Endometrial ultrasonography is simple to learn because of the reliable identification of the uterus. It is useful for monitoring fertility treatment, evaluation of abnormal bleeding and monitoring patients in the menopause.

Abstract
OBJECTIVE To determine preovulatory uterine sonographic predictors of pregnancy in women undergoing ovulation induction for assisted reproductive treatments. DESIGN Prospective evaluation of uterine sonographic and vascular flow profiles in women stimulated with leuprolide acetate and hMG. SETTING Private fertility center and tertiary-care academic center. PATIENTS Ninety-six women underwent 102 cycles of ovulation induction for IVF (46), GIFT (20), and zygote intrafallopian transfer (36). MAIN OUTCOME MEASURES Endometrial texture, thickness, resistance index at the first branch of uterine artery, diastolic blood flow, and pregnancy outcome (no conception, spontaneous abortion, and delivery). RESULTS Triple-lined pattern was predominant in women who delivered liveborn infants (P < 0.005). Endometrial pattern and diastolic blood flow were the only predictive markers of term pregnancy (P < 0.001 and P < 0.05, respectively). CONCLUSION Preovulatory triple-lined sonographic endometrial texture and the presence of end diastole blood velocities at the first branch of uterine artery are the most important uterine predictors of conception.

Abstract
The possible antiestrogenic effect of clomiphene citrate on endometrial growth was assessed by serial transabdominal ultrasonographic measurements in 46 women with unexplained infertility. A significantly higher (p < 0.05) rate of endometrial growth was observed in the 8 women who conceived compared with the 38 women who failed to conceive. A thicker endometrium (4.6 +/- 0.3 mm) was observed from the third day before ovulation as well as a higher average growth rate in the three days prior to ovulation (0.7 +/- 0.1 mm/day) in the group that achieved pregnancy compared to a lower endometrium (2.1 +/- 0.2 mm) from the third day before ovulation and a slower growth rate in the three days prior to ovulation (0.2 +/- 0.0 mm/day) in the group that did not achieve pregnancy (p < 0.05). These data suggest that clomiphene citrate may exert an antiestrogenic effect on the endometrium, and thus interfere with implantation.

Abstract
OBJECTIVE To determine if preovulation endometrial thickness or pattern are related to fecundity and to use of clomiphene citrate (CC) or hMG in IUI. DESIGN Prospective ultrasound evaluation the day of hCG after CC alone (n = 197), hMG alone (n = 49), concurrent hMG or sequential CC and hMG (n = 205), and no medications (n = 23). SETTING Private fertility clinic. PATIENTS Two hundred seventy-one patients undergoing 474 cycles of IUI. MAIN OUTCOME MEASURES Endometrial thickness, pattern, per cycle fecundity, and continuing pregnancy. RESULTS Endometrial thickness was related to fecundity and continuing pregnancy. No pregnancies occurred when thickness was < 6 mm. The continuing pregnancy rate was 12.6% when thickness was > or = 9 mm, compared with 6.9% when thickness was 6 mm to 8 mm. Endometrial pattern was unrelated to pregnancy. Average endometrial thickness was decreased when hMG and CC were used in combination (7.9 mm) compared with hMG alone (9.4 mm). Endometrial thickness was negatively related to CC dose and positively related to the day of hCG administration by ANOVA. CONCLUSIONS Endometrial thickness the day of hCG administration is prognostic of fecundity and continuing pregnancy in cycles of ovulation induction.

Abstract
Diagnostic curettage has for many years been the method of choice to diagnose endometrial cancer in women with postmenopausal bleeding. The costs for curettage performed today are huge, and approximately only 10% in this group of women will be diagnosed with endometrial cancer. Thus less expansive techniques to obtain endometrial samples have been evaluated, but all of them are invasive. The value of endovaginal ultrasonography for identifying endometrial abnormality in this group of women has not been evaluated until now. This study used endometrial thickness as measured by endovaginal ultrasonography as an indicator of endometrial abnormality. It was demonstrated in 205 women with postmenopausal bleeding that if the endometrium was less than 9 mm thick, no endometrial cancer was found at curettage. The mean endometrial thickness in those women with endometrial cancer was 18.2 +/- 6.2 mm as compared with 3.4 +/- 1.2 mm in those women with atrophic endometrium. If the cutoff limit for endometrial abnormality was 5 mm, the positive predictive value for identifying endometrial abnormality was 87.3%. If this limit had been used in this study, 70% of the curettage procedures could have been avoided.

Abstract
Transvaginal sonography was used and endometrial response patterns of 3 groups of patients (Spontaneous cycles, hMG cycles, and Clomiphene Citrate cycles) were observed based on endometrial characteristics of thickness and texture. All groups demonstrated cyclical changes evident by transvaginal sonography. Clomiphene Citrate cycles showed retardation of endometrial growth during the proliferative phase and delayed endometrial development based on textural patterns. There exists a positive correlation between estrogen levels and endometrial thickness in induced cycles, which is not observed in spontaneous cycles. There were no correlations between hormonal levels of progesterone, FSH and LH, in relation to endometrial characteristics of thickness and texture.

Abstract
The texture and the thickness of the endometrium as assessed by transvaginal sonography were prospectively evaluated in 123 patients undergoing IVF treatment. Three different types of endometrial patterns could be distinguished: (A) an entirely homogenous, hyperechogenic endometrium; (B) an intermediate type characterized by the same reflectivity of ultrasound as the myometrium, with a nonprominent or absent central echogenic line; and (C) a multilayered endometrium consisting of prominent outer and midline hyperechogenic lines and inner hypoechogenic regions. On the day before oocyte retrieval, endometrial thickness was significantly greater in the group of patients who achieved pregnancy than in the group who did not (8.7 +/- 0.4 vs 7.5 +/- 0.2 mm, respectively; P less than 0.01) and significantly more patients had multilayered, pattern C, endometrium (75% in pregnant women vs 42.4% in nonpregnant women; P less than 0.01). No pregnancy occurred when the endometrial thickness was less than 6 mm. When type C endometrium greater than or equal to 6 mm thick was seen, the pregnancy rate per embryo transfer was 39%. When type A or B endometrial pattern was seen, the negative predictive value for the occurrence of pregnancy was 90.5%. Our results suggest that transvaginal sonographic evaluation of endometrial texture and thickness may be an indicator of the likelihood of achieving pregnancy.

Abstract
It is estimated that as many as 15% of married couples are affected by fertility disorders. The number of such couples seeking medical help has increased dramatically in the past 10 years due to both relative and absolute factors. The increase in population, the rising rate of sexually transmitted diseases, and the reduced availability of adoptable infants all contribute to the magnitude of this problem. The role of diagnostic imaging in the effective and compassionate care of couples desiring offspring is the subject of this review. Infertility is a disorder of a couple, not of two individuals. The diagnostic evaluation, therefore, must include both partners. Hysterosalpingography and ultrasound constitute the mainstay of the evaluation of the female member. The various techniques and complications of hysterosalpingography are reviewed. The normal appearance of the uterine cavity together with a review of the numerous anomalies and variations that might be encountered are presented. Along similar lines, the possible filling defects, synechiae, postoperative changes, and other alterations that may be encountered in imaging the uterine cavity are described. Evaluation of the fallopian tubes is of paramount importance, primarily to assess patency but also to assess the possibility of patent but diseased salpinges or disease of the surrounding peritubal tissue. Recently, interventional techniques using radiographic and sonographic control have been developed and are beginning to demonstrate promising results in the management of fallopian tube obstruction. These procedures, adapted from previously established radiographic interventive techniques, are discussed. The role of diagnostic imaging of the male partner is of lesser magnitude. Clinical assessment and semen evaluation generally permit adequate assessment of the male factor. Occasionally, however, vasography and seminal vesiculography are called into play. More frequently, sonographic evaluation to establish the presence of varicoceles is necessary. Such techniques are reviewed, as well as the interventional approaches for ablating varicoceles. The application of conventional and transvaginal sonography in the management of gynecologic fertility disorders is reviewed. Follicular monitoring, guided follicle aspiration, assessment of the status of the endometrium, guided embryo transfer and tubal cannulation, and evaluation of other pelvic disorders are significant factors in the appropriate management of the infertile couple.(ABSTRACT TRUNCATED AT 400 WORDS)

Abstract
In 45 women from an in vitro fertilization (IVF) program, the uterine and ovarian blood flows were investigated by vaginal Doppler sonography. The resistance index was used to evaluate the blood pattern. When comparing the patients who became pregnant after embryo transfer (ET [group I, n = 12]) with those who did not conceive (group II, n = 33), it is evident that in group I the vascular resistance of the uterine arteries is significantly lower on the day of follicular aspiration. No differences could be detected in the ovarian vessels. The data obtained so far suggest that the receptivity of the endometrium is a crucial factor for successful implantation. In the final analysis, this can be appraised not only on the basis of morphological but also of hemodynamic parameters.

Abstract
The present study was undertaken to evaluate endometrial thickness and the amount of endometrial growth (delta) in patients who conceived during in vitro fertilization (IVF) (n = 36) compared with matched women who did not conceive (n = 72). Estradiol (E2) and endometrial thickness were measured daily from cycle day 10 to the day after human chorionic gonadotropin (hCG). Mean endometrial thickness and E2 levels on cycle day 10 did not differ. On the day before ovum retrieval, significantly thicker endometrium was observed in the pregnant than in the nonpregnant women (8.6 +/- 0.3 [SEM] and 7.1 +/- 0.3 mm, respectively; P less than 0.0005), whereas the mean E2 levels did not differ. The delta endometrial growth was greater in the women who conceived than in the nonpregnant group (4.3 +/- 0.2 and 2.5 +/- 0.2 mm, respectively; P less than 0.0005). The fertilization rate and serum E2 levels did not correlate with endometrial thickness nor with delta endometrial growth. Our data suggest that the amount of endometrial growth during ovarian hyperstimulation and the endometrial thickness on the day before oocyte retrieval deserve further study as possible predictive parameters for implantation.

Abstract
Endometrial thickness and reflectivity were assessed by transvaginal ultrasound in both spontaneous and hyperstimulated menstrual cycles. Two groups of women with ovulatory cycles were examined; women in group 1 had unexplained infertility and women in group 2 were having artificial insemination by donor because of reduced spermatogenesis; a third group (group 3) comprised women with tubal infertility undergoing hyperstimulation for in-vitro fertilization. There was no difference in endometrial thickness or reflectivity between the three groups. A basic pattern of endometrial appearance common to all cycles was found, consisting of hypoechoic, isoechoic and hyperechoic images, occurring in the early follicular, late follicular and luteal phases, respectively. In all three groups a positive correlation was found between proliferative phase plasma oestradiol concentration and endometrial thickness. Group 1 r = 0.403, P less than 0.01; group 2 r = 0.439, P less than 0.01; and group 3 r = 0.617, P less than 0.01. There was a progressive increase in endometrial growth throughout the normal cycle until a plateau was reached 5 days after the LH surge. This pattern was also seen without acceleration of the process in hyperstimulated cycles, despite supranormal levels of oestrogen. Assessment of endometrial thickness is not a useful variable in monitoring hyperstimulated cycles. No aberrations of endometrial growth or pattern were observed in the women with unexplained infertility.

Abstract
Using real-time ultrasound, a study was undertaken to evaluate the morphology of normal uterus in the neonate delivered at term. The uterus was visualized in 41 (89.1%) of the 46 neonates. The cervical volume (CE-V) was 3.65 +/- 1.36 cm3, the corporeal volume (CO-V) 1.18 +/- 0.42 cm3, and the CE-V was significantly larger than the CO-V (p less than 0.001). The uterine volume (U-V) was 4.83 +/- 1.57 cm3, and U-V showed a good correlation with birth weight (r = 0.42, p less than 0.01). The endometrial echo was constantly depicted as a mixed echo of a highly echogenic line and/or a myometrial halo. These normal values and the morphology of the neonatal uterus provide useful information for distinguishing a possible pathologic pelvic mass and screening of congenital genital disorders.

Abstract
Ultrasonic volume evaluation of the endometrium was performed on 19 spontaneously ovulating and 48 ovulation-induced women and correlated to E2 and P values in peripheral blood. No statistical correlations were obtained between either hormone level and any of the sonographically obtained parameters except for E2 levels in reference to the anteroposterior diameter of the endometrium in stimulated cycles (R = 0.29; P less than 0.05). It is concluded that the sonographic evaluation of the endometrium does not contribute to the evaluation of either spontaneous or induced cycles.

Abstract
The thickness of the endometrium was compared in 15 patients who conceived and 15 who did not with an in vitro fertilization and embryo transfer (IVF-ET) protocol after ovulation induction with human menopausal gonadotropin/human chorionic gonadotropin (hMG/hCG). There was no statistically significant difference (P = 1.0) in the endometrial thickness in the conception versus the nonconception group. Average estradiol (E2) values and number of mature follicles were also not statistically different in the two groups (P = 0.78, P = 0.81). There was a slightly significant difference in the number of embryos transferred in the conception versus nonconception groups (2.5 versus 1.9, P = 0.005). However, the most significant difference between the conception and nonconception groups was the total number of oocytes retrieved (4.4 versus 2.8, P = 0.005). These findings indicate that there are no sonographically detectable differences in the endometrial thickness in patients who achieve pregnancy versus those that do not when given a similar ovulation induction regimen of hMG/hCG for IVF-ET.

Abstract
This work was undertaken for evaluation of the value of endometrial thickness as an early predictor for the success of in vitro fertilization (IVF). Endometrial changes were evaluated ultrasonographically in 47 women undergoing IVF. A high-dose gonadotropin protocol was used for induction of multiple follicular development. Thirty-seven women did not conceive following the procedure (group I), and 10 conceived (group II). Ultrasonographic endometrial measurements were performed repeatedly throughout the cycle. Serum 17 beta-estradiol and progesterone levels were evaluated concomitantly. Three consecutive growth patterns of the endometrium were observed. The first was a rapid one with a daily growth rate of about 0.5 mm from approximately 9 mm on day -3 to 12 mm on day +2 (day 0 being the day of human chorionic gonadotropin administration). The second phase, following follicular aspiration, showed a decrease in growth rate to about 0.1 mm per day until day +11, when a thickness of about 13 mm was measured. In group I growth was arrested from day +11 until menstruation, whereas in group II an accelerated growth rate of about 0.4 mm per day could be demonstrated from day +14 onward. Endometrial growth did not correlate with serum estradiol or progesterone levels. No conception occurred with an endometrial thickness below 13 mm on day +11. It is concluded that endometrial thickness follows a distinct pattern of growth in human menopausal gonadotropin-induced cycles and does not correlate with serum sex hormones.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
Ultrasonography is a noninvasive technique for studying the characteristics of the endometrium. This method was used in our in vitro fertilization and embryo transfer program during the periovulatory period for determination of whether there exists a moment at which the uterine mucosa is most favorable for implantation of the ovum. The endometrial thickness was noted in the course of the periovulatory phase. No correlation was found between the ultrasound image and hormonal assays. The endometrial thickness was significantly greater (P less than 0.01) when the in vitro fertilization attempt resulted in a pregnancy, even when considering the number of embryos transferred. However, it was not possible to predict the probability of pregnancy with the use of endometrial thickness.

Abstract
Diagnostic ultrasound offers unique possibilities to study ovarian morphology, especially follicular growth and development. This makes the technique an important tool for the management of ovulation induction in an in vitro fertilization and embryo replacement (IVF/ER) program. Different general aspects of the use of ultrasound in IVF/ER are discussed in this communication.
