Serum thyroid-stimulating hormone receptor antibody levels and thyroid dysfunction after hysterosalpingography: a case-control study.

OBJECTIVE: Hysterosalpingography (HSG) performed with an iodine contrast media can cause thyroid dysfunction, including thyrotoxicosis and hypothyroidism. We investigated the association between the serum levels of thyroid-stimulating hormone receptor antibody (TRAb), an indicator of Graves' disease, and abnormal thyroid function after performing HSG. METHODS: The screening of TRAb was conducted in 362 patients who first visited the Tawara IVF Clinic between April and September 2018. The association between TRAb levels and the effects of HSG examinations on thyroid function were evaluated. RESULTS: Of the 362 patients, 2 (0.55%) had high levels (>2.0 IU/L) of TRAb, whereas 18 (5.0%) had intermediate TRAb levels, ranging from 0.3 to 1.9 IU/L. Of the 98 women (including 7 of the 18 women with TRAb level 0.3-1.9 IU/L, and 91 of the 342 women with TRAb level <0.3 IU/L) who had undergone HSG, two women developed overt thyrotoxicosis after HSG, and the frequency was significantly higher (p = .0044) in the group with intermediate levels of TRAb (28.6%, 2 of 7) than that in the group with low TRAb levels (<0.3 IU/L; 0.0%, 0 of 91). CONCLUSIONS: These findings indicate that increased serum levels of TRAb are significantly associated with the development of thyrotoxicosis after HSG.

Use of atropine in four-dimensional hysterosalpingo-contrast sonography: Does it suppress pain during infertility examination?

This study aimed to ascertain if atropine is useful for suppressing the pain suffered during four-dimensional hysterosalpingo-contrast sonography (4D-HyCoSy) when assessing infertility in women. A total of 252 patients were divided into 2 groups to receive or not receive atropine (0.5 mg) injection 30 minutes before 4D-HyCoSy. Pain was evaluated using a numerical rating scale (NRS): during 4D-HyCoSy; upon 2-dimensional transvaginal sonography; before catheter insertion; upon insertion and fixation of the catheter into the uterine cavity; 30 minutes after 4D-HyCoSy. According to the degree of patency of Fallopian tubes, the 6 patterns observed were integrated further into 3 patient groups: all-negative (both Fallopian tubes were negative), positive-and-negative (one Fallopian tube showed patency and the other showed stenosis or non-patency), and all-positive (both Fallopian tubes showed stenosis or non-patency). We compared the NRS scores and prevalence of side-effects other than pain between the atropine-injection and non-atropine-injection groups within the three groups mentioned above. The NRS score showed no significant differences among the groups at any time point (all P > .05). The different prevalence of side-effects other than pain was significant between the atropine-injection and atropine-non-injection groups (P = .012). These data suggest that atropine does not reduce pain in patients during 4D-HyCoSy. However, atropine may reduce the prevalence of other side-effects during 4D-HyCoSy, which needs a further, large, prospective, multi-cohort study to verify.

Evaluation of the Cervix After Cervical Conization by Transvaginal Elastography.

OBJECTIVES: The purpose of this study was to investigate the stiffness of the cervix after the loop electrosurgical excision procedure (LEEP) by transvaginal elastography and its potential ability to predict future pregnancy. METHODS: A retrospective study included patients of reproductive age who underwent LEEP for cervical high-grade squamous intraepithelial lesions on the basis of colposcopic findings and who desired fertility. The characteristics on conventional transvaginal ultrasonography and elastography before and 6 months after LEEP were reviewed and analyzed. Each case had a 12-month follow-up, and the information on pregnancy and a cervical cytologic examination was recorded. RESULTS: Fifty-three patients who completed the 12-month follow-up were included in the analysis. Thirty-two cases (group 1) were pregnant during the follow-up, and the other 21 (group 2) had pregnancy failure. The cervical lengths of group 1 and 2 as measured by traditional transvaginal ultrasonography were similar before and 6 months after LEEP. The resistive index of group 1 was significantly higher 6 months after LEEP than before LEEP (mean ± SD, 0.88 ± 0.36 versus 0.42 ± 0.22; P = .007). The mean elasticity score for the cervix was statistically significantly lower after LEEP (2.21 ± 0.53) than before (3.46 ± 0.78; P = .001) in group 1. However, in group 2, the mean elasticity scores were similar after LEEP (3.19 ± 0.58) and before (3.25 ± 0.66; P = .75). CONCLUSIONS: Our results suggest that elastography was a useful technique for evaluating the stiffness of the cervix after LEEP. Elastography could provide a potential means to predict future pregnancy after LEEP.

Subfertility: What the Radiologist Needs to Know.

The role of imaging in subfertility is well established but is changing. In addition to traditional fertility assessments, there is an emerging role for the radiologist. The role of imaging in fertility-restoring procedures in benign disease and congenital malformations is evolving, and there is a growing need for accurate identification of young candidates suitable for fertility-preserving surgery in the oncologic setting. To facilitate this developing role, knowledge of the key imaging modalities used and potential therapeutic applications is important for accurate diagnosis and interpretation by the radiologist. ©RSNA, 2017.

MicroRNA expression profiling in endometriosis-associated infertility and its relationship with endometrial receptivity evaluated by ultrasound.

OBJECTIVE: To investigate the microRNA expression profiling in endometriosis-associate infertility, and relationship between the microRNA expression and endometrial receptivity evaluated by ultrasound. METHODS: First, miRNA expression profiling difference of ectopic endometrium between 8 endometriosis patients and 6 endometriosis-free patients were compared. Bioinformatics analyses detected 61 differentially expressed (DE) known miRNAs and 57 DE novel miRNAs. Next, other 24 patients were selected for checking the microRNAs in differential expression by RT-PCR. Among them, case and control groups include 14 endometriosis and 10 endometriosis-free infertility patients, respectively. Last, endometrial receptivity of other 20 endometriosis patients was evaluated by ultrasound. In this group of patients, 12 had high endometrial receptivity, in which infertility is caused by fallopian tube occlusion, and 8 had low endometrial receptivity. The study compared endometrial miRNAs expression between two groups, and also evaluated the relationship between the endometrial miRNAs expression and the endometrial receptivity. RESULTS: First, study indicated that "proteinaceous extracellular matrix," "laminin binding" and "extracellular matrix binding" were enriched in 6 up-regulated miRNA targets, while "cell proliferation" was enriched in the 4 down-regulated miRNA targets. Second, 10 miRNAs in different expression (miR-1304- 3p, miR-544b, miR-3684, miR-494-5p, miR-4683, miR-6747-3p; miR-3935, miR-4427, miR-652-5p, miR-205-5p) were detected by RT-PCR, and the results showed statistically significant differences between 2 groups in all 10 miRNAs. Third, the expression levels of miR-1304-3p, miR-494-5p, and miR-4427 were different between the two groups with different endometrial receptivity. But for the miR-544b, there was no statistically significant difference between two groups. CONCLUSIONS: The study provided a comprehensive understanding to the current knowledge in the field of miRNAs in endometriosis and the relationship between them and the endometrial receptivity. miRNAs could be used as diagnostic biomarkers and therapeutic agents for this disease. The combination of ultrasound and miRNAs detection could be a better choice for the diagnosis of infertility in the future.

Laparoscopic Repair of Cesarean Scar Defect "Isthmocele".

STUDY OBJECTIVE: To demonstrate the technique of laparoscopic repair of a large cesarean scar defect (isthmocele). DESIGN: Case report (Canadian Task Force classification III). SETTING: Cesarean scar defect, also known as an isthmocele, is the result of incomplete healing of the isthmic myometrium after a low transverse uterine incision performed for cesarean section. Although mostly asymptomatic, it may cause menstrual abnormalities (typically postmenstrual spotting), chronic pelvic pain, and secondary infertility. Scar tissue dehiscence, scar pregnancy, and abnormally adherent placenta are some of the obstetric complications associated with this defect. No standardized treatment has yet been accepted. Hysteroscopy and laparoscopy are the minimally invasive approaches currently used to repair the defect. INTERVENTION: A 40-year-old patient, G2P2, presented with postmenstrual spotting and secondary infertility for the past 2 years. She had a history of 2 previous cesarean deliveries. Transvaginal ultrasound revealed a large (2.5 × 1.5 cm) niche. Thickness of the myometrium over the defect was 3 mm. Laparoscopic repair of the uterine defect was performed. The bladder that was densely adherent to the lower uterine segment was freed by careful dissection. The defect was then localized with a sharp curette placed transcervically into the uterus. The curette was pushed anteriorly to delineate the margins of the defect and puncture the ceiling of the isthmocele cavity. The fibrotic tissue that formed the ceiling and the lateral borders of the defect was excised using laparoscopic scissors. Reapproximation of the edges was done with continuous nonlocking 3-0 V-Loc sutures. The procedure took 90 minutes, and there were no associated complications. Postoperative ultrasound performed in the second month after the operation showed a minimal defect measuring 0.5 cm, with a residual myometrial thickness of 7 mm. At the time of this writing, the patient was free of symptoms. CONCLUSION: Laparoscopic repair, although not standardized, is a minimally invasive procedure that can be performed to treat uterine scar defects. Mobilization of the overlying bladder, resection of the isthmocele margins and secondary suturing of the remaining myometrial tissue appears to be an effective treatment option for affected patients.

Sonographic appearances of the postoperative testis.

PURPOSE: To describe the sonographic findings observed in the testis in patients who have undergone testicle-sparing surgery and surgical biopsies. METHODS: We reviewed the color Doppler sonographic findings from 14 patients after testicular interventions: 2 open biopsy procedures for infertility and 12 testicle-sparing surgical procedures (1 for spontaneous intratesticular hemorrhage and 11 for small tumors). Ten patients had benign tumors; one had a malignancy. Three patients were symptomatic; all others were studied as follow-up. RESULTS: Hypoechoic and hypovascular lesions at site of surgery were seen in 10 of the 11 patients after tumorectomy; no changes were observed in one patient. The lesions were either linear or an irregularly triangular shape, located at the surgical site, and interpreted as scars. Retraction of the testicular surface was detected in two cases. In the eight patients who underwent follow-up, lesions disappeared in one case, became smaller in two, and remained stable in five. Of the two patients who underwent biopsy, one developed peritesticular hematoma, and both had late hypoechoic scars in the testis. CONCLUSIONS: Hypoechoic and hypovascular scars are a "normal" postoperative pattern after testicle-sparing surgery. They are either linear or triangular, with rectilinear margins. Such findings need to be correctly interpreted and not misinterpreted as recurrences.

Use of colour and spectral Doppler ultrasonography in stallion andrology.

Doppler ultrasonography is an important tool in the andrological evaluation in humans; however, this method is not so extensively used by equine andrologists. Spectral or pulse Doppler is a useful non-invasive method for the early diagnosis of subfertility problems in the male, especially those triggered by vascular disturbance. The identification of any disturbance in the blood flow of the testis is crucial for a correct diagnosis of various testicular and scrotal disorders but also to monitor the therapeutic outcome following treatment. The aim of this review is to provide an update on the current use of colour and spectral Doppler ultrasound in stallion andrology, and to promote the use of this technique during the soundness reproductive examination of the stallion, as this particular branch of reproductive medicine is receiving increasing interest.

Accuracy of 3-dimensional sonography for diagnosis and classification of congenital uterine anomalies.

OBJECTIVES: Congenital abnormalities of the müllerian ducts are not very common, yet they contribute to the problem of infertility. The purpose of this study was to determine the sensitivity and specificity of 3-dimensional (3D) sonography for diagnosis of congenital uterine abnormalities. METHODS: This study was performed in 214 women with fertility problems who were suspected to have müllerian anomalies at Arash Hospital from April 2010 to April 2011. All patients underwent 3D sonography to assess for uterine anomalies during the luteal phase of the spontaneous cycle. Sonography was performed by one radiologist, after which one surgeon performed a hysteroscopy and a laparoscopy in each of the patients while under general anesthesia. The 3D sonographic results were not available to the surgeon. Finally, the results were compared to determine the sensitivity, specificity, and accuracy of 3D sonography. RESULTS: Final evaluations of 204 patients showed uterine anomalies in 84.3% of the patients. For diagnosis of uterine anomalies, the sensitivity of 3D sonography was 86.6%, and specificity was 96.9%. The positive predictive value was 99.3%, and the negative predictive value was 54.4%, with an 88.2% accuracy rate. For classification, the positive predictive value of 3D sonography was 82.3%, and accuracy was 76%; without short septa and arcuate uteri, accuracy was 95%. CONCLUSIONS: It seems that 3D sonography has a high level of accuracy for most uterine anomalies. In the case of an arcuate uterus and short septa, more precision and increased experience will improve accuracy.

First experiences with hysterosalpingo-foam sonography (HyFoSy) for office tubal patency testing.

BACKGROUND: This study was conducted to describe the first experiences with hysterosalpingo-foam sonography (HyFoSy) as a first step routine office procedure for tubal patency testing. METHODS: A prospective observational cohort study was started in a university affiliated teaching hospital. In 2010, 73 patients with subfertility and a low risk of tubal pathology were examined. A non-toxic foam containing hydroxymethylcellulose and glycerol was applicated through a cervical applicator for contrast sonography (HyFoSy). Tubal patency was determined by transvaginal ultrasonographic demonstration of echogenic dispersion of foam in the Fallopian tube and/or the peritoneal cavity. Only in case patency could not be demonstrated, a hysterosalpingography (HSG) was performed as a control. RESULTS: In 67 out of 73 (92%) patients, a successful procedure was performed. In 57 out of 73 (78%) cases, there was no further need for a HSG. In five patients (5/73; 7%) tubal occlusion was confirmed by HSG and in five patients (5/73; 7%) there was discordance between HyFoSy and HSG. Of 73 patients, 14 (19%) conceived within a median of 3 months after the procedure. CONCLUSIONS: HyFoSy is a successful procedure to demonstrate tubal patency as a first step office procedure.

Correlations between antral follicle count and ultrasonographic ovarian parameters and clinical variables and outcomes in IVF cycles.

AIMS: To assess the correlation between the antral follicle count (AFC) and other ultrasonographic parameters and clinical variables in in vitro fertilization (IVF) cycles. METHODS: Pretreatment ultrasonographic evaluation included AFC (total), large (5-10 mm) and small (2-4 mm) antral follicles, ovarian volume, and ovarian Doppler indices. Data were prospectively uploaded and subsequently analysed in relation to IVF cycle results. RESULTS: The study included 128 women (128 cycles). Analysis of body mass index (BMI) yielded a weak significant correlation with large (5-10 mm) AFC but not with other sonographic variables. AFC was significantly correlated with patient age, ovarian volume, number of retrieved oocytes, total dose of used gonadotropins, peak estradiol, number of top-quality embryos, and number of frozen embryos and marginally correlated with number of aspirated immature oocytes. Lower large (5-10 mm) AFC was the only ovarian parameter associated with oral contraception pretreatment compared to nontreatment, even after adjustment for age and BMI. There was no difference in any of the parameters between short and long IVF cycles. CONCLUSIONS: BMI is only weakly correlated with AFC. Pretreatment with oral contraceptives may be associated with lower AFC. Pretreatment with gonadotropin-releasing hormone agonist (long protocol) does not alter the ultrasonographic ovarian parameters.

Elevated body mass index correlates with higher seminal plasma interleukin 8 levels and ultrasonographic abnormalities of the prostate in men attending an andrology clinic for infertility.

BACKGROUND: Obesity is associated with a systemic, low-grade inflammatory state. Although the relationship between obesity and semen parameters or prostate diseases has been previously investigated, the association between body mass index (BMI), prostate inflammatory diseases and color- Doppler ultrasound (CDU) of the male genital tract (MGT) has been poorly studied. AIM: To evaluate the association between BMI and CDU features of the MGT, signs and symptoms of prostate inflammation, semen parameters. MATERIALS/SUBJECTS AND METHODS: We studied 222 men seeking medical care for couple infertility. According to the World Health Organization classification, subjects were divided into 3 groups: normal weight (no.=131, BMI=18.5-24.9 kg/m2), overweight (no.=71, BMI=25.0-29.9 kg/m2), obese (no.=20, BMI≥30.0 kg/m2). All patients underwent simultaneous testosterone evaluation and seminal analysis, including interleukin 8 (sIL-8), along with scrotal and transrectal CDU, before and after ejaculation. Prostatitis symptoms were evaluated by National Institutes of Health- Chronic Prostatitis Symptom Index questionnaire. RESULTS: After adjusting for age and testosterone levels, higher BMI was significantly related to higher prostate volume and several CDU features of the prostate, including macro-calcifications, inhomogeneity, higher arterial peak systolic velocity (the latter adjusted also for blood pressure), but not with abnormalities of testis, epididymis, seminal vesicles. Furthermore, higher BMI and BMI class were significantly related to higher sIL-8, a reliable surrogate marker of prostate inflammatory diseases, even after adjustment for age. Conversely, no associations among BMI, clinical symptoms of prostatitis or semen parameters were observed. CONCLUSIONS: Subjects with higher BMI might develop CDU and biochemical signs suggestive of prostate inflammation, although not clinically overt.

Endometrial osseous metaplasia in a patient with secondary infertility referred for hysterosalpingogram with ultrasound.

Endometrial osseous metaplasia is a rare entity resulting in the formation of trabecular bone fragments within the uterine cavity and frequently presents as secondary infertility with a history of previous pregnancy loss or termination. The unusual transvaginal ultrasound appearances are important to recognise, as fertility is often restored after hysteroscopic removal of the bone fragments from the uterine cavity.

Endometrial thickness is not predictive for live birth after embryo transfer, even without a cutoff.

OBJECTIVE: To investigate the predictive value of endometrial thickness (EMT) for live birth when a lower threshold of EMT is not employed for embryo transfer (ET). DESIGN: Retrospective study SETTING: Academic assisted reproduction center PATIENT(S): All women who underwent fresh or frozen-thawed ET at the Koç University Hospital Assisted Reproduction Unit between October 2016 and August 2019 INTERVENTION(S): After ruling out endometrial pathology, blastocyst transfer was planned regardless of the EMT in the absence of increased serum progesterone level on the trigger day in fresh embryo transfer cycles or before commencing progesterone treatment in artificially prepared frozen-thawed ET cycles. MAIN OUTCOME MEASURE(S): The primary outcome was live birth. Live birth and miscarriage rates per ET were stratified according to fresh and frozen-thawed ET cycles for each millimeter of endometrial thickness. Receiver operator characteristic curve analyses were performed to evaluate the predictive value of EMT for live birth. RESULT(S): A total of 560 ET cycles, 273 fresh and 287 frozen-thawed, were included in the study. Relevant patient characteristics as well as EMTs were similar between women who achieved a live birth and those who did not after fresh or frozen-thawed ET. There was no linear association between EMT and live birth or miscarriage rates. Area under the curve values for EMT to predict live birth after fresh, frozen-thawed, and all ETs were 0.56, 0.47, and 0.52, respectively. CONCLUSION(S): Our results showed that the EMT was not predictive for live birth in either fresh or frozen-thawed ET cycles. Once intracavitary pathology and inadvertent progesterone exposure were excluded, women with thinner EMTs should not be denied their potential for live birth because it is comparable to that of those with thicker EMT.

Predictive Factors of Conception and the Cumulative Pregnancy Rate in Subfertile Couples Undergoing Timed Intercourse With Ultrasound.

The aim of this study was to determine predictive factors for pregnancy and assess the cumulative pregnancy rate (CPR) and live birth rate (CLBR) in subfertile couples undergoing timed intercourse (TI) using ultrasound. This retrospective cohort study included 285 women (854 cycles) who started TI with ultrasound between January 2017 and October 2019. The overall clinical pregnancy rate was 28.1% (80/285) per couple and 9.4% (80/854) per cycle. Pregnant women had a higher body mass index (BMI), higher percentage of irregular menstrual cycles, a shorter duration of subfertility, lower serum follicle-stimulating hormone levels, and higher anti-Müllerian hormone levels than non-pregnant women. A longer duration of subfertility (≥24 months vs. <12 months; odds ratio: 0.193; 95% confidence interval: 0.043-0.859) and endometriosis (vs. ovulatory factors; odds ratio: 0.282; 95% confidence interval: 0.106-0.746) as causes of subfertility were unfavorable factors that independently affected clinical pregnancy. In subgroup analysis, old age ≥ 35 years [vs. < 35 years; odds ratio: 0.279; 95% confidence interval: 0.083-0.938), a longer duration of infertility ≥24 months (vs. <24 months; odds ratio: 0.182; 95% confidence interval: 0.036-0.913) and a higher BMI ≥ 25 kg/m2(vs. >25 kg/m2; odds ratio: 3.202; 95% confidence interval: 1.020-10.046) in couples with ovulatory factor and a longer duration of infertility ≥24 months (vs. <24 months; odds ratio: 0.185; 95% confidence interval: 0.042-0.819) in couples with non-ovulatory factors were significant independent predictive factors for pregnancy. No significant differences were found in the cycle characteristics between pregnant and non-pregnant women. The CPR substantially increased during the first three cycles and significantly increased until the sixth cycle. No significant increase was observed in the CPR after the sixth cycle. The CLBRs substantially increased during the first three cycles and significantly increased until the fourth cycle. No significant increase was observed in the CLBRs after the fifth cycle. When comparing CPRs and CLBRs according to subfertile causes, CRPs was significantly different and CLBRs was different with borderline significance. Our findings may indicate that women with a longer duration of subfertility or subfertility due to endometriosis have poor outcomes during TI with ultrasound. Women who failed to achieve conception by the fourth or fifth cycle of TI with ultrasound may be encouraged to consider advancing to the next treatment strategy.

Optimal lead follicle size for human chorionic gonadotropin trigger in clomiphene citrate and intrauterine insemination cycles: an analysis of 1,676 treatment cycles.

OBJECTIVE: To identify the optimal lead follicle size for hCG trigger in clomiphene citrate (CC)-intrauterine insemination (IUI) cycles. DESIGN: Retrospective cohort study. SETTING: University-affiliated center. PATIENT(S): Patients <40 years of age with ovulatory dysfunction or unexplained infertility undergoing their first CC-IUI cycle. INTERVENTION(S): Ovulation induction, hCG trigger, and IUI. MAIN OUTCOME MEASURE(S): Clinical pregnancy rate (CPR) was the primary outcome and was plotted against lead follicle size in increments of 1 mm. Odds ratios with 95% confidence intervals for associations between lead follicle size and CPR were calculated from a multivariable logistic regression model. A receiver operating characteristic (ROC) curve was generated for CPR as a function of lead follicle size. RESULT(S): 1,676 cycles were included. The overall CPR was 13.8% (232/1,676). There was no difference in baseline demographics or ovulation induction parameters of patients who did or did not conceive. The odds of clinical pregnancy were 2.3 and 2.2 times higher with lead follicle sizes of 21.1-22.0 mm and >22.0 mm, respectively, compared with the referent category of 19.1-20.0 mm. Lead follicle size was an independent predictor of CPR, even after accounting for confounders. A lead follicle size of 22.1 mm corresponded to a sensitivity and specificity of 80.1% and 90.4% for clinical pregnancy, respectively, with an area under the ROC curve of 0.89. CONCLUSION(S): hCG administration at a lead follicle size of 21.1-22.0 mm is associated with higher odds of clinical pregnancy in patients undergoing their first CC-IUI cycles for ovulatory dysfunction or unexplained infertility.

Role of endometrial blood flow assessment with color Doppler energy in predicting pregnancy outcome of IVF-ET cycles.

This is a prospective study of 182 women (38 yrs or younger) undergoing IVF-ET. Endometrial thickness, echo pattern and blood flow on transvaginal ultrasonography were recorded eight hours prior to hCG administration. The patients were divided into three groups: A (n = 10) with undetectable endometrial blood flow; B (n = 82) with sub-endometrial blood flow; C (n = 90) with both endometrial and sub-endometrial blood flow. According to IVF-ET outcomes, all patients were re-divided into three groups: 1 non-pregnancy (n = 92); 2 intrauterine pregnancy with live fetus (n = 70); 3 others (n = 20 including biochemical pregnancy, embryonic diapause, ectopic pregnancy and miscarriage). Intrauterine pregnancy with live fetus in Group C (62.2%) was much higher than that in Group A and B (0% and 17.1%, p less than or equal to 0.001). The implantation rate (33.2%) was much higher than that in Group A and B (0% and 19.90%, p less than or equal to 0.001). The pulsatility index, resistance index, and S/D of endometrial spiral arteries were 0.1 +/- 0.2, 0.6 +/- 0.1 and 2.5 +/- 0.4 in Group 2, which were much lower than those in Group 1 and Group 3 (p1-2 less than 0.001, p2-3 less than 0.05). The patients with detectable endometrial blood flow had higher clinical pregnancy rates and implantation rates.
