Association between Myometrial Thickness and Assisted Reproductive Technologies Outcomes: A Prospective Cohort Study.

BACKGROUND: Myometrial thickness has been expected to be a prognosticator for lower uterine segment function. An abnormal function of the uterine muscle layer can cause common and important reproductive problems. This study aimed to evaluate the relationship between baseline myometrial thickness and assisted reproductive technologies (ART) outcomes. MATERIALS AND METHODS: In this prospective cohort study, 453 infertile women undergoing ART cycles without any obvious uterine pathology, participated in this prospective cohort study from February 2013 to May 2015. In order to measure the myometrial thickness in the anterior and posterior of the uterine, trans-vaginal ultrasounds were conducted on days 2-4 of the cycle (menstrual phase) preceding ovarian stimulation and the day of human chorionic gonadotropin (hCG) injection. We defined three groups based on the baseline myometrial thickness in the anterior and posterior, including (A) <25 mm, (B) 25-29.9 mm and (C) ≥30 mm. Ovarian stimulation, oocyte retrieval and luteal phase support were performed in accordance with the standard long protocol. Two weeks after embryo transfer, the patients underwent a pregnancy test by checking their serum ß-hCG levels. The primary outcome measure was clinical pregnancy rate. Secondary outcome measures were, implantation rate, abortion rate and live birth rate. RESULTS: The clinical pregnancy (P=0.013) and implantation (P=0.003) rates were significantly lower in group A than in two other groups. Although the live birth rate was lower in group A than two other groups, this decrease was not statistically significant (P=0.058). CONCLUSION: The findings may be a way for clinicians to draw focus on providing therapeutic strategies and a specific supportive care for women with a baseline myometrial thickness <25 mm in order to improve the reproductive outcome of in vitro fertilization/intracytoplasmic sperm injection (IVF-ICSI).

Does The Culture of Post-Thawed Cleavage-Stage Embryos to Blastocysts Improve Infertility Treatment Outcomes of Frozen-Thawed Embryo Transfer Cycles? A Randomised Clinical Trial.

BACKGROUND: There is a definite shift in assisted reproductive centres from cleavage-stage embryo transfer (ET) to blastocyst transfer that is attributed to improvements in laboratory environments and advances in the development of embryo culture media. The aim of the study was to investigate the reproductive outcomes of thawed cleavage-stage ET versus blastocysts derived from an extended culture of these embryos. MATERIALS AND METHODS: This open-label, randomised, parallel group clinical trial study enrolled 182 women aged ≤37 years who underwent frozen-thawed ET from November 2015 to June 2020 at Royan Institute Research Centre, Tehran, Iran. The women were randomly assigned to either the thawed cleavage ET group (n=110) or the post-thaw extended culture blastocysts group (n=72). The primary outcome measure was the clinical pregnancy rate. Secondary outcome measures were implantation rate, live birth rate (LBR), and miscarriage rate. A P<0.05 indicated statistical significance. RESULTS: There were no significant differences between the two groups in terms of demographic characteristics. Both the mean numbers of embryos transferred and good quality embryos transferred were significantly lower in the postthaw extended culture blastocysts group compared to thawed cleavage-stage ET cycles. However, the post-thaw extended culture blastocysts group had higher clinical pregnancy (56.94 vs. 40.91%, P=0.034), implantation (34.43 vs. 19.84%, P=0.001) and live birth (49.3 vs. 33.63%, P=0.036) rates compared to the thawed cleavage-stage ET group. Miscarriage and multiple gestations rates were comparable between the groups. CONCLUSION: These results allow us to take a position in favour of post-thaw extended culture blastocysts; thus, it is important to improve the post-thawing extended culture technique (registration number: NCT02681029).

Embodying Time in the Brain: A Multi-Dimensional Neuroimaging Meta-Analysis of 95 Duration Processing Studies.

Time is an omnipresent aspect of almost everything we experience internally or in the external world. The experience of time occurs through such an extensive set of contextual factors that, after decades of research, a unified understanding of its neural substrates is still elusive. In this study, following the recent best-practice guidelines, we conducted a coordinate-based meta-analysis of 95 carefully-selected neuroimaging papers of duration processing. We categorized the included papers into 14 classes of temporal features according to six categorical dimensions. Then, using the activation likelihood estimation (ALE) technique we investigated the convergent activation patterns of each class with a cluster-level family-wise error correction at p < 0.05. The regions most consistently activated across the various timing contexts were the pre-SMA and bilateral insula, consistent with an embodied theory of timing in which abstract representations of duration are rooted in sensorimotor and interoceptive experience, respectively. Moreover, class-specific patterns of activation could be roughly divided according to whether participants were timing auditory sequential stimuli, which additionally activated the dorsal striatum and SMA-proper, or visual single interval stimuli, which additionally activated the right middle frontal and inferior parietal cortices. We conclude that temporal cognition is so entangled with our everyday experience that timing stereotypically common combinations of stimulus characteristics reactivates the sensorimotor systems with which they were first experienced.

Evaluation of the relationship between vitamin D levels with oocyte quality in breast cancer women: a cross-sectional study.

Recent evidence suggests that vitamin D deficiency could play an important role in the development of non-skeletal diseases, including cancer. Vitamin D also affects the function of the reproductive system. In the present study, the relationship between 25(OH)D levels with oocyte quality in Breast Cancer (BC) women and control group have been investigated. After initial evaluations, ovarian stimulation began with the GnRH antagonist protocol in the BC group (N = 16) and control group (N = 16). The serum and follicular fluid (FF) 25(OH)D levels were measured at the time of oocyte retrieval and their relationship to oocyte quality was examined. The mean levels of serum and FF 25(OH)D in BC women were significantly lower than in the control group (22.26 ± 7.98 vs. 29.61 ± 9.12, P = 0.02, 21.65 ± 7.59 vs. 28.00 ± 9.05, P = 0.04, respectively). There was a significant correlation between the levels of 25(OH)D in FF and serum in BC women (r = 0.873, P < 0.001). But there was no correlation between the serum or FF 25(OH)D levels with the parameters related to oocytes (P > 0.05). In the BC women, the number of dysmorph and highly dysmorph oocytes was higher than in the control group (P < 0.001). Women with BC referring to infertility centers for fertility preservation are more likely to be deficient in serum 25(OH)D level; this subsequently affects the FF 25(OH)D level. However, serum and FF 25(OH)D levels may not be suitable indicators for examining maturity and quality of oocytes in terms of morphology in BC women, and the poor morphological quality of oocytes in BC women may be due to other factors.

Comparison of sexual function in infertile women with polycystic ovary syndrome and endometriosis: A cross-sectional study.

Background: Infertility is one of the issues affecting sexual function (SF). Infertility is also one of the complications of polycystic ovary syndrome (PCOS) and endometriosis. Objective: This research seeks to assess and compare SF and the prevalence of sexual dysfunction in infertile women with PCOS and endometriosis. Materials and Methods: A cross-sectional study was carried out with a sample of 630 (210 infertile women with endometriosis, 210 infertile women with PCOS, and 210 healthy women of childbearing age as the control group). SF was assessed by the female sexual function index (FSFI). Descriptive statistics and inferential statistics were used to analyze the data. The primary outcome measured was FSFI score. Secondary outcome was hospital anxiety and depression scale score. Results: The results showed that the mean score of the total FSFI in the 2 groups of PCOS and endometriosis was lower than the control group (p < 0.001). In addition, women with higher education (university education) had a higher total FSFI. Conclusion: Sexual dysfunction rates are high in infertile women with endometriosis and PCOS. Infertility service providers in infertility centers need to pay attention to this issue.

Does prevalence of sexual dysfunction differ among the most common causes of infertility? A cross-sectional study.

BACKGROUND: Sexuality as a fundamental component of women's health, can be affected by infertility. The current study aimed at comparing the prevalence of sexual dysfunction among women with the most common causes of infertility. METHODS: The current cross-sectional study was conducted on 240 infertile females with infertility due to polycystic ovary syndrome (PCOS, n = 80), endometriosis (n = 80) and male factor (n = 80) at Royan Institute for Reproductive Biomedicine (Tehran, Iran) and 160 fertile women at health care centers, between May 2016 and June 2017. Sexual function was assessed by Female Sexual Function Index (FSFI). Data were analyzed using SPSS (version 25.00) and differences were regarded statistically significant at p < 0. 05. RESULTS: The prevalence of female sexual dysfunction was 98.8% in women with PCOS, 100.0% in those with endometriosis, and 80.0% in those with male factor infertility. Overall, 36.2% of the enrolled fertile women were suffering from sexual dysfunction. CONCLUSIONS: There was an association between the prevalence of female sexual dysfunction or individual domain scores of the FSFI, and infertility etiologies. Therefore, infertility care providers are required to take this into consideration and develop preventive strategies in this regard. Infertility as a major health care problem affects an estimated 8-12% of couples of reproductive age globally and sexuality as an important part of women's health, can be affected by infertility. In this study, the prevalence of sexual dysfunction among women with the most common causes of infertility has been evaluated. The present study was conducted on 240 infertile females with infertility due to polycystic ovary syndrome (PCOS, n = 80), endometriosis (n = 80) and male factor (n = 80) at Royan Institute (Tehran, Iran) and 160 fertile women at health care centers, between May 2016 and June 2017. Sexual function was assessed by Female Sexual Function Index (FSFI); a brief self-report measure of sexual functioning. Results highlight that the prevalence of sexual dysfunction in women with endometriosis and PCOS was higher than in other groups. As, the prevalence of female sexual dysfunction was 98.8% in women with PCOS, 100.0% in those with endometriosis, and 80.0% in those with male factor infertility. In total, 36.2% of the enrolled fertile women were suffering from sexual dysfunction. The results point to an association between the prevalence of female sexual dysfunction and causes of infertility. Therefore, infertility care providers are required to take this into consideration and develop preventive strategies in this regard.

Comparison of various aspects of women's lives between infertile and women with and without tubal ligation: a comparative cross-sectional study.

BACKGROUND: The aim of this study is to compare anxiety, depression, body image, self-esteem, sexual function, and quality of life (QoL) between infertile women and control fertile women undergoing tubal ligation (TL) and using condom. METHODS: This cross-sectional study was conducted on 600 women in three groups of infertile and control fertile women with or without TL (200 women in each group), who met the inclusion criteria. They were selected from Royan Institute and a number of health care centers in Tehran (Iran) from May 2017 to February 2019. The subjects were asked to fill out the Short Form Health Survey (SF-12), Female Sexual Function Index (FSFI), Hospital Anxiety and Depression Scale (HADS), Body Image Concern Inventory (BICI), and Rosenberg' Self-Esteem Scale (RSES). One-way ANOVA was used to identify the possible statistical differences between the three groups of participants. RESULTS: The mean scores of all FSFI domains were lower in the control TL women, and the differences between the three groups in all dimensions were statistically significant. In addition, the TL group had more female sexual dysfunction (FSD) comparing to the infertile and condom group (22.43 ± 5.30, 24.79 ± 4.74, and 28.03 ± 3.29, respectively P < 0.001). There was a significant difference between the three groups in SF-12 scores (76.59 ± 13.14, 68.49 ± 14.47, and 78.87 ± 12.62, respectively P < 0.001). Also there was a significant difference between the three groups in anxiety, depression, and total scores of HADS (P < 0.001). Furthermore, infertile women had lower body image (P < 0.05) and the TL group had lower self-esteem comparing to the two other groups (P < 0.05). CONCLUSIONS: The findings revealed the adverse effects of using TL on the anxiety, depression, sexual life, body image, and QoL of women. It is recommended that health-care professionals should increase their awareness and knowledge regarding the side-effects of using TL on women's lives and share this information with the patients.

Diet and The Risk of Endometriosis in Iranian Women: A Case-Control Study.

BACKGROUND: Endometriosis is one of the most common pelvic diseases associated with dyspareunia, pelvic pain, and infertility. The primary aim of this study is to evaluate the role of diet on the risk of endometriosis among Iranian women. MATERIALS AND METHODS: This case-control study was conducted in two health research centres between 2015 and 2016. There were 207 women with endometriosis (case) and 206 women without endometriosis (control) who were evaluated by laparoscopy. The women were asked about their frequency of consumption per week of portions of selected dietary items in the Iranian diet in the year before the interview. RESULTS: The results indicated that intake of green vegetables (odds ratio [OR]=0.39, 95% confidence interval [CI]=0.21-0.74, Ptrend=0.004), red meat (OR=0.61, 95% CI=0.41-0.91, Ptrend=0.015) and dairy products (milk [OR=0.65, 95% CI=0.47-0.92, Ptrend=0.014], cheese [OR=0.53, 95% CI=0.37-0.76, Ptrend<0.001]), fresh fruit (OR=0.68, 95% CI=0.50-0.93, Ptrend=0.015) and grain legumes (OR=0.59, 95% CI=0.47-0.77; Ptrend<0.001) had a significant association with lower risk of endometriosis. Consumption of carrots, green tea, fish, eggs and oil was not significantly related to the risk of endometriosis. CONCLUSION: This study suggests that certain types of dietary components may be related to the risk of endometriosis.

Pain Perception and Side Effects During Saline Infusion Sonohysterography With a Balloon Catheter: A Randomized Comparative Study of Cervical Versus Intrauterine Catheter Placement.

OBJECTIVES: This study aimed to evaluate whether the site of the balloon placement into either the uterine cavity or cervical canal can affect the intensity of pain during sonohysterography. METHODS: In this randomized clinical trial, women who underwent saline infusion sonohysterography (SIS) were randomized to intracervical or intrauterine balloon placement between May 2012 and May 2014. The examination was scheduled at the early follicular phase of the menstrual cycle. The primary outcome measures included the degree of pain after inflation and then after deflation of the balloon catheter. Data were analyzed on the basis of the intention-to-treat principle for each woman who underwent SIS. RESULTS: A total of 300 infertile women were assigned to the treatment groups. There were no significant differences in inflation and deflation pain and the total procedure time between the 2 groups. The total volume of required saline for adequate distention of the cavity was significantly lower in the cervical group than the intrauterine group (p = .015). Nulliparous women had insignificantly more pain after the initial inflation of the balloon compared with multiparous women (p = .069). The pain score was not associated with patients' age, the volume of the saline infused, the presence of intrauterine abnormality, and the procedure time. CONCLUSIONS: Intracervical catheter placement did not reduce pain during or after SIS. However, intracervical balloon insertion requires a less-significant volume of saline compared with intrauterine placement, leading to a reduced risk of intrauterine infection and the spread of malignant endometrial cells into the peritoneal cavity at the time of the procedure.

Randomized controlled trial of gonadotropin-releasing hormone agonist microdose flare-up versus flare-up among poor responders undergoing intracytoplasmic sperm injection.

OBJECTIVE: To compare the effect of gonadotropin-releasing hormone (GnRH) agonist microdose flare-up and GnRH agonist flare-up protocols among women with poor ovarian reserve undergoing intracytoplasmic sperm injection (ICSI) cycles. METHODS: Randomized controlled trial study among 131 women with poor ovarian reserve who underwent ICSI cycles at a single center in Tehran, Iran, between September 2008 and May 2014. Eligible women were randomly assigned to either the microdose flare-up (n=66) or flare-up (n=65) protocol. The primary outcome measure was live birth rate. RESULTS: Both groups were comparable in cycle cancellation, mean number of dominant follicles, retrieved oocytes, and metaphase II oocytes. Number of stimulation days (P=032) and endometrial thickness (P=0.001) were significantly higher, and gonadotropin dose was non-significantly higher (P=0.075) in the microdose flare-up group than in the flare-up group. No difference in clinical pregnancy, implantation, or abortion rate was observed between the two protocols. Live birth was higher in the microdose flare-up group than in the flare-up group (P=0.036). CONCLUSION: The microdose flare-up protocol seemed to be superior to the flare-up protocol, but it required a higher dose of gonadotropins and a longer duration of stimulation. Further prospective clinical trials of the microdose flare-up protocol are recommended. CLINICALTRIALS.GOV: NCT01006954.

The Effect of Vaginal Sildenafil on The Outcome of Assisted Reproductive Technology Cycles in Patients with Repeated Implantation Failures: A Randomized Placebo-Controlled Trial.

BACKGROUND: The aim of this study was to investigate the effects of vaginal sildenafil on the outcome of patients with at least two unsuccessful in vitro fertilization/intracytoplasmic sperm injection (IVF/ICSI) attempts. MATERIALS AND METHODS: In this randomized placebo-controlled trial study, a total of 66 infertile women aged ≤38 years, with a history of normal ovarian reserve, two prior consecutive failed IVF/ICSI attempts, human chorionic gonadotropin (hCG) day endometrial thickness <7 mm in all prior IVF/ICSI cycles, normal endometrial appearance by either hysteroscopy, hysterosonography, or hysterosalpingography enrolled in this study. The conventional gonadotropin-releasing hormone (GnRH) protocol was used for ovarian stimulation. The patients were randomly divided into three groups: vaginal sildenafil (suppository-100 mg/daily), vaginal placebo/sildenafil (suppository-100 mg/daily), and vaginal placebo (suppository). Each patient underwent colour Doppler ultrasound on day 14 of their previous cycle to investigate any abnormalities in the uterus and adnexa. Endometrial thickness, echo pattern, uterine artery resistance, and pulsatility indices were recorded pre- and post-treatment. The primary outcome measures were implantation, chemical and clinical pregnancy rates. For data analysis, SPSS version 20 software was used. In all tests, the significance level was considered less than 0.05. RESULTS: There was no significant difference between three groups in endometrial thickness on the hCG injection day. The chemical pregnancy in women who received sildenafil (alone or in combination with placebo) showed a two-fold increase in comparison to the placebo group. This increase was clinically meaningful, but according to sample size, it was statistically non-significant. The results of our study showed that the implantation was higher in women who received placebo/sildenafil compared to the other groups. The abortion rate was not statistically significant among the groups. CONCLUSION: Vaginal sildenafil may conceivably improve chemical pregnancy rates in repeated IVF failure patients. Further randomized clinical trials using oral or vaginal sildenafil with higher sample size are recommended (Registration number: NCT03192709).

Does low-dose aspirin improve pregnancy rate in women undergoing frozen-thawed embryo transfer cycle? A pilot double-blind, randomized placebo-controlled trial.

AIM: To evaluate the effect of adjuvant low-dose aspirin therapy on clinical pregnancy rate and uterine perfusion in women undergoing frozen-thawed embryo transfer (FET) cycles. METHODS: This study was performed as a pilot randomized, double-blind placebo-controlled trial, from May 2012 to February 2015. Overall, 60 available eligible women who were candidates for FET were randomly assigned to two groups receiving either 100 mg oral aspirin (n =30) or placebo (n =30). The primary outcome measure was clinical pregnancy rate. Secondary outcome measures were pulsatility index (PI), resistance index (RI), implantation rate, live birth rate and miscarriage rate. RESULTS: There was no significant difference in endometrial thickness, PI and RI. However, the study group had higher rates of clinical pregnancy, implantation, live birth (P = 0.042, P = 0.031 and P = 0.007, respectively) and lower rate of miscarriage (P = 0.020) as compared to the control group. Twin birth rate was comparable between the two groups. CONCLUSION: Our pilot study demonstrated that administration of low-dose aspirin in FET cycles results in better pregnancy, implantation and live birth rates without changing the uterine hemodynamics or endometrial thickness. However, further randomized clinical studies in larger populations are needed to confirm these findings.

Is preterm placental calcification related to adverse maternal and foetal outcome?

This prospective cohort study aimed to evaluate the role of premature placental calcification in adverse pregnancy outcomes and identify its associated potential risk factors. We consecutively enrolled 293 women who presented to three academic medical centres from September 2011 to March 2013. Participants underwent transabdominal sonographies between 28-36 weeks of gestation in an attempt to determine placental maturity. We compared maternal and foetal outcomes between two groups of women, those with grade III placenta (n = 69) and those without grade III placenta (n = 224). Passive smoking was the only predictor of early placental calcification. There were more abnormal Doppler, low birth weight (LBW) and caesarean section (CS) deliveries observed in the preterm calcification group. No definite relationship existed between maternal hypertension (HTN), diabetes and other medical diseases with placental calcification. In conclusion, umbilical artery (UA) resistance index (RI) and absent or reversed end-diastolic velocity (AREDV) were observed more often in preterm placental calcification. Serious antepartum follow-up should be advised for these mothers. Impact Statement • Placental calcification is a physiological phenomenon but normally, a grade III placenta is not frequently found until 36 weeks of gestation (so is called preterm placental calcification - PPC). There is currently a lack of consistent evidence on the clinical significance of PPC and pregnancy outcome. The present study was designed to evaluate the role of PPC in adverse pregnancy outcomes. • In our study, although none of the pregnant women were smokers, we found that passive smoking was the only predictor of PPC. Abnormal umbilical artery Doppler waveforms considerably and absent end diastolic velocity pattern significantly were observed more often in the PPC group. • We observed that PPC can be a landmark for high-risk pregnancy and an alarm sign for placental dysfunction. So, close antepartum follow up should be advised for these mothers. Regular and frequent foetal wellbeing tests should be done to prevent pregnancy complications. Certainly larger and more extensive study can provide more valid results.

Is Coasting Valuable in All Patients with Any Cause of Infertility?

OBJECTIVES: This study aimed to assess the influence of coasting duration on the number and quality of oocytes and fertilization rate in male factor infertile women and those with polycystic ovary syndrome (PCOS). METHODS: In this prospective observational follow-up study, 114 patients undergoing coasting (53 women with male factor infertility and 61 women with PCOS) were evaluated at the Royan Institute Research Center, Iran, between 2010 and 2012. RESULTS: The results were analyzed according to the coasting periods of 1-4 days. In normal females, the number of oocytes retrieved was significantly reduced after the second day (p = 0.004). In addition, a statistically significant drop was observed in the number of metaphase II oocytes and fertilization rate after the third day (p = 0.006 and p = 0.006, respectively). No significant differences were observed in the number and quality of oocytes retrieved and fertilization rate with regard to coasting days in PCOS patients. CONCLUSION: Coasting with duration of more than three days should be performed with caution in normal females who are at risk of developing ovarian hyperstimulation syndrome.

Urine-Based Nested PCR for the Diagnosis of Mycobacterium tuberculosis: A Comparative Study Between HIV-Positive and HIV-Negative Patients.

BACKGROUND: While tuberculosis (TB) can be diagnosed by microscopy and culture, the sensitivity of Ziehl-Neelsen staining is variable and culture results require 4 - 8 weeks to be determined. Polymerase chain reaction (PCR) and its modifications, including nested PCR, might be promising methods for the rapid diagnosis of TB. OBJECTIVES: This study aimed to evaluate the performance of nested PCR on urine samples of human immunodeficiency virus (HIV)-positive and -negative patients with different manifestations of clinical TB. METHODS: In a prospective study, three early-morning urine samples from 100 patients with pulmonary TB (PTB) or extrapulmonary TB (EPTB) were evaluated using a molecular target with insertion element IS6110, specific to the Mycobacterium tuberculosis genome, and nested PCR was performed. The results were analyzed with SPSS version 22. RESULTS: A total of 100 patients, including 74 (74%) with PTB and 26 (26%) with EPTB, were enrolled. Positive smears were seen in 38 patients (38%). Lymph nodes were the most commonly involved organ in 14 of the 26 (53.8%) EPTB patients (13.5%). Seven (23.1%) of the EPTB patients were HIV-positive. Urine PCR was positive in only 28 patients (28%). Seven HIV-positive patients with PTB showed positive urine PCR results. Moreover, PCR results were positive in only one of the seven HIV-positive subjects with EPTB. Positive PCR results were found in 20 of the 73 HIV-negative patients (27.4%) and in 8 of the 27 HIV-positive patients (29.6%). Therefore, there was no significant difference between the HIV-negative and HIV-positive patients for urine PCR (sensitivity 29.6%, specificity 72.6%; positive and negative predictive values 28% and 72%, respectively; P = 0.138). CONCLUSIONS: Nested PCR showed the same sensitivity in HIV-positive and HIV-negative patients. It can be applied as a rapid technique for the diagnosis of TB.

Metabolic syndrome in infertile women with polycystic ovarian syndrome

ABSTRACT Objective The aim of the present study was to determine the prevalence of metabolic syndrome (MS) in infertile Iranian women with polycystic ovary syndrome (PCOS) using the ATPIII criteria. Subjects and methods In this cross-sectional study, 624 women with PCOS were enrolled at a tertiary referral center in Tehran, Iran, between April, 2012 and March, 2013. Diagnosis of MS was according to ATPIII criteria. Also, we divided PCOS patients into following two main groups: (i) with MS (n = 123) and (ii) without MS (n = 501), and then compared variables between two groups. Results The mean age, body mass index (BMI) and waist circumference were 28.6 ± 4.3 years, 26.7 ± 3.7 kg/m2 and 85.2 ± 8.7 cm, respectively. The prevalence of MS was 19.7%. Our findings showed that age, BMI, waist circumference and all metabolic parameters were higher in PCOS women with MS than related values in those without MS. The most and least prevalent forms of MS were low level of high density lipoprotein-cholesterol (HDL-C) and hypertension, respectively. Conclusion It seems the prevalence of metabolic syndrome in our country isn’t as high as western countries. The prevalence rate of MS increased with age and BMI. One of the major cardiovascular risk factors, low level of HDL-C, is the most prevalent metabolic abnormality in our participants.

Our findings showed that age, BMI, waist circumference and all metabolic parameters were higher in PCOS women with MS than related values in those without MS. The most and least prevalent forms of MS were low level of high density lipoprotein-cholesterol (HDL-C) and hypertension, respectively. CONCLUSION: It seems the prevalence of metabolic syndrome in our country isn't as high as western countries. The prevalence rate of MS increased with age and BMI. One of the major cardiovascular risk factors, low level of HDL-C, is the most prevalent metabolic abnormality in our participants.

Empty Follicle Syndrome: The Possible Cause of Occurrence.

OBJECTIVES: Empty follicle syndrome (EFS), although rare, is a disappointing condition in which no oocytes are retrieved from mature follicle after ovulation induction in in vitro fertilization (IVF) cycles. The aim of this study was to estimate the incidence and factors associated with EFS. METHODS: All cycles resulting in EFS from May 2012 to September 2013 were retrospectively identified at a tertiary referral infertility center. Among the 3,356 cycles performed, 58 (1.7%) women who underwent their first IVF cycle and had no oocyte retrieval were enrolled in the study. Three different stimulation protocols (long, antagonist, and miniflare) were mainly used for induction of follicular growth. Data relating to the age, follicle stimulating hormone (FSH) level, anti-Müllerain hormone (AMH) level, and the number of ampules and follicles for each patient was obtained. RESULTS: Out of 58 individuals, 10 (17.2%) showed false type and 48 (82.8%) showed genuine EFS. The most frequent findings in our study were diminished ovarian reserve, low anti-Müllerian hormone (AMH; ≤0.5 ng/mL), and less than four mature follicles, indicating EFS in 1.7% of the patients. CONCLUSION: Low serum AMH levels and a small number of follicles after ovarian stimulation is the manifestation of diminished ovarian reserve. Thus, we suggest that EFS could be a manifestation of low ovarian reserve.

A randomized controlled trial evaluating the effect of ethinyl estradiol during clomiphene citrate cycles among women with polycystic ovary syndrome.

OBJECTIVE: To investigate the effects of low-dose ethinyl estradiol (EE) on the clinical pregnancy rate among women with polycystic ovary syndrome (PCOS) undergoing ovulation induction with clomiphene citrate (CC). METHODS: Between March 12, 2011, and February 10, 2013, a randomized, double-blind, placebo-controlled trial was conducted at the Royan Institute Research Center, Tehran, Iran, among women with PCOS who were aged 25-30 years, were undergoing their first intrauterine insemination cycle, and had a history (≥2 years) of infertility, oligomenorrhea, or amenorrhea. Participants were randomly allocated to receive EE (0.05 mg daily for 5 days) or placebo, co-administered with CC cycles (100 mg daily for 5 days). The primary outcome was clinical pregnancy rate. Analyses were per protocol: patients who discontinued the intervention were excluded. RESULTS: Analyses included 45 women who received CC and EE, and 50 women who received CC and placebo. The number of women who achieved a clinical pregnancy was higher among participants who received CC and EE (13 [29%]) than among those in the control group (5 [10%]; P =0 .02). No adverse effects of EE were reported. CONCLUSION: The combination of CC and EE seems to increase the clinical pregnancy rate among women with PCOS undergoing intrauterine insemination.
