Abstract Background: Intake of resveratrol has been associated with improved ovarian morphology under in vitro and in the animal models; however, this finding has not been confirmed in trials. The aim of our study was, therefore, to use a placebo-controlled approach with the detailed assessment of the ovarian morphology by applying transvaginal ultrasound to examine the effectiveness of this therapeutic approach in this group of women. Methods: Forty-one women with polycystic ovary syndrome (PCOS) were randomly assigned (1:1) to 3 months of daily 1000 mg resveratrol or placebo. Random assignment was done by blocked randomisation. Our primary endpoints were the change in the ovarian volume, stromal area and antral follicle count per ovary (FNPO) from the baseline to 3 months. Secondary endpoints were improvement in the distribution of follicles and ovarian echogenicity. Differences between the resveratrol and control groups were evaluated by Chi-square, fisher’s exact test and repeated-measures of ANOVA. Results: The mean age of all participants was 28.61 ± 4.99 years, with the mean BMI of 28.26 ± 5.62 kg/m2. Resveratrol therapy, as compared with placebo, was associated with a significantly higher rate of improvement in the ovarian morphology (p= 0.02). Women who received resveratrol had a more dominant follicle than those getting placebo, with a significant reduction in the ovarian volume (p<0.05). However, the number of FNPO, stromal area, ovarian echogenicity and distribution of follicles were not significantly altered (P>0.05). Conclusions: Treatment with resveratrol significantly reduced the ovarian volume and PCOM, thus suggesting a disease-modifying effect in PCOS. Trial registration: IRCT, IRCT2017061917139N2.

Aim: To compare the rate of ovarian hyperstimulation syndrome in women with and without polycystic ovarian syndrome, and to determine the cut-off for the antral follicle count and the anti-Müllerian hormone level predictive of ovarian hyperstimulation syndrome in both groups. Methods: This was a prospective cohort study conducted in women aged 20–35 years who were undergoing controlled ovarian stimulation. The women were divided into those with polycystic ovarian syndrome and the controls on the basis of the Rotterdam criteria. The outcome of stimulation was recorded, and the ovarian response markers were compared in both groups. Results: Among 689 women included in the study, 276 (40.1%) had polycystic ovarian syndrome, and 476 (59.9%) were used as the controls. Ovarian hyperstimulation syndrome occurred in 19.6% of the cases, and in 7.7% of the controls (p <0.001). The conception rate was greater in the group of cases (52.5% vs. 16.5%, p = 0.001). Among the cases, the sensitivity and specificity for the prediction of hyper-response were 94.4% and 97.3% for AFC, and 92.6% and 93.7% for the anti-Müllerian hormone, at the cut-off values of ≥18 and ≥6.425 ng/ml, respectively. Among the controls, the sensitivity and specificity for the prediction of hyper-response were 93.8% and 97.1% for the antral follicle count, and 93.6% and 94.5% for the anti-Müllerian hormone, at the cut-off values of ≥10 and ≥3.95 ng/ml, respectively. Conclusion: Group-specific values should be used to identify and counsel women undergoing controlled ovarian stimulation. In light of available evidence, gynaecologists should be trained to perform ultrasound evaluation, determine the antral follicle count of their patients, and offer them appropriate counselling.

Abstract The pathophysiology of iron-induced compromised fertility in women with thalassemia major (TM) was evaluated in 26 adult TM females. Low gonadotropin secretion resulted in reduced ovarian antral follicle count and ovarian volume, but levels of anti-müllerian hormone (AMH), a sensitive marker for ovarian reserve independent of gonadotropin effect, were mostly normal. AMH correlated with non–transferrin-bound iron (NTBI), suggesting a role of labile iron in the pathogenesis of decreased reproductive capacity, possibly occurring in parallel to cardiac iron toxicity, as cardiac iron was associated with the presence of amenorrhea and with NTBI levels. AMH emerges as an important biomarker for assessment of reproductive capacity in TM, demonstrating that fertility is preserved in the majority of those younger than 30 to 35 years. AMH can be useful in future studies aiming at improved chelation for fertility preservation, whereas NTBI and labile plasma iron may be valuable for monitoring iron effect on the reproductive system.

The objective was to evaluate the possible relationships between AFC, ovarian volume, ovarian follicle reserve and oocyte quality in abattoir-derived ovaries (experiment 1) and in cows (experiment 2) submitted to OPU. Antral follicle counts of ≥25, 16 to 24, and ≤ 16 were used to define AFC classes as high (HAFC), intermediate (IAFC), and low (LAFC) in both experiments. In experiment 1, after antral follicles were aspirated, abattoir ovaries (n = 10 per AFC class) were processed by conventional histology and pre-antral follicles were counted within primordial, primary, secondary, and tertiary classes and classified as either healthy or degenerate under regular microscopy (Cushman et al. 1999). In experiment 2, HAFC (n = 42), IAFC (n = 34), and LAFC (n = 29) cows were submitted to OPU and oocytes classified as grades 1, 2, and 3 or degenerate (IETS, 2010). Antral follicles (≥3 mm in diameter) were counted by ultrasonography. Data were analysed by GENMOD and GLM procedures of SAS (SAS Institute Inc., Cary, NC, USA) after transformations, when required. In experiment 1, mean normal primordial follicle number was higher (P < 0.001) in HAFC (137.0 ± 1.6)a compared with IAFC (52.6 ± 1.9)b and LAFC (20.2 ± 5.3)c ovaries. However, the mean number of degenerate primordial follicles was lower (P < 0.001) in low count ovaries (2.4 ± 0.6) compared with HAFC (19.0 ± 4.7) and IAFC (16.4 ± 1.5, P < 0.001). Normal primary follicle number was higher in the HAFC compared with IAFC and LAFC ovarian classes (86.2 ± 7.0a v. 34.6 ± 5.1b and 14.4 ± 3.3c, respectively; P < 0.01). Degenerate primary follicles were higher in the HAFC compared with LAFC ovarian class (16.8 ± 6.5 v. 5.2 ± 2.64; P < 0.05). Normal secondary follicle number was also higher in the HAFC compared to LAFC ovarian classes (25.2 ± 7.67 v. 2.4 ± 0.8; P < 0.05). The number of degenerate secondary follicles differed (P < 0.01) only between the IAFC and the LAFC ovarian classes (0.6 ± 0.4 and 7.2 ± 2.4, respectively), which were similar (P > 0.5) to the HAFC class (3.8 ± 1.0). In experiment 2, grade 1, 2, and 3 oocytes, viable oocytes, and ovarian volume (mm3) were higher (P < 0.001) in HAFC compared with IAFC and LAFC cows (grade 1: 7.9 ± 0.6a, 4.9 ± 0.7b and 3.3 ± 0.7c; grade 2: 4.0 ± 0.4a, 2.8 ± 0.4b and 1.2c; grade 3: 2.1 ± 0.4a, 2.5 ± 0.4a and 1.3 ± 0.5b, respectively; viable oocytes: 16.3 ± 1.1a, 13.1 ± 1.2b, and 8.1 ± 1.3c, respectively; (volumes: 12.6 ± 0.7a, 10.1 ± 0.8b, and 8.1 ± 0.9c, respectively). In conclusion, high AFC is linked to a higher follicular reserve, oocyte quality, and ovarian volume. It is safe to apply AFC in the selection of bovine females without compromising oocyte or pre-antral follicular population qualities.
