J Ovarian Res 2021; 14:111. [PMID: 34454544 PMCID: PMC8403432 DOI: 10.1186/s13048-021-00863-4] [Citation(s) in RCA: 9] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/21/2021] [Accepted: 08/18/2021] [Indexed: 12/17/2022] Open
Abstract
Background Recent studies have consistently shown that AFC and serum AMH are good predictors of ovarian response and have shown strong correlations. However, it is not unusual for reproductive medicine specialists to encounter discordance between them. This is the first study to investigate the efficacies of the different COS protocols when the AFC and AMH levels are discordant. Based on the association between COS protocols and pregnancy outcomes, we attempt to explain the controversial results and clarify the predictive value of AMH and AFC in this context. Methods 19,239 patients undergoing their first fresh in vitro fertilization (IVF)/intracytoplasmic sperm injection (ICSI) cycles with GnRH antagonist protocols, GnRH-a long protocols or GnRH-a ultra-long protocols between January 1, 2016, and December 31, 2019, were enrolled and then divided into four groups in accordance with the boundaries for the AFC and serum AMH level provided by the Poseidon Classification. Our study was divided into two parts. Firstly, we retrospectively compared the effects of the three COS protocols in patients with discordant AMH and AFC. Multivariate logistic regression models were conducted in a forward manner to exclude the influence of confounding factors. Afterward, to increase comparability between Group 2 (low AMH and normal AFC) and Group 3 (normal AMH and low AFC), propensity score matching (PSM) analysis was performed based on age, BMI, the number of embryos transferred, and COS protocol. IVF intermediate and reproductive outcomes were compared between Group 2 and Group 3. Results For people with low AMH and normal AFC (Group 2), the number of total oocytes, clinical pregnancy rate (CPR), live birth rate (LBR) and cumulative live birth rate (CLBR) were significantly higher in GnRH-a ultra-long protocol compared with GnRH antagonist protocol. In multivariate logistic regression models, significant associations of COS protocol with fresh LBR and CPR were found after adjusting for age, BMI, AFC, AMH and the number of embryos transferred. Whereas, in patients with normal AMH and low AFC (Group 3), the number of total oocytes, CLBR, LBR and CPR were highest in the long GnRH-a protocol although there was no statistically significant difference. After PSM, the results showed that although oocytes yield and available embryos in patients with normal AMH and low AFC were significantly higher, there was no significant difference in reproductive outcomes between Group 2 and Group 3. Conclusions We found that women with normal AFC and low AMH may benefit from the GnRH-a ultra-long protocol. Nevertheless, for women with normal AMH and low AFC, the long GnRH-a protocol seems to be associated with better clinical outcomes. Furthermore, after eliminating the confounding factors including the COS protocol, we found that AMH can only predict the number of oocytes but not the quality of oocytes when there was discordance between AFC and AMH.

Anti-müllerian hormone levels and antral follicle count in women with a BRCA1 or BRCA2 germline pathogenic variant: A retrospective cohort study. Breast 2021; 59:239-247. [PMID: 34304065 PMCID: PMC8326804 DOI: 10.1016/j.breast.2021.07.010] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/22/2021] [Revised: 07/05/2021] [Accepted: 07/08/2021] [Indexed: 12/22/2022] Open
Abstract
Background Some studies suggested a decreased ovarian reserve among BRCA1/2 pathogenic variant carriers, with conflicting results. Methods We conducted a retrospective single-center observational study of ovarian reserve and spontaneous fertility comparing BRCA1/2 pathogenic variant carriers to controls (women who attended consultations to discuss fertility preservation before gonadotoxic treatment). Measures of associations between plasma AMH concentration, AFC and BRCA1/2 status were modelled by nonlinear generalized additive regression models and logistic regressions adjusted for age at plasma storage, oral contraceptive use, body mass index, cigarette smoking, and the AMH assay technique. Results The whole population comprised 119 BRCA1/2 pathogenic variant carriers and 92 controls. A total of 110 women (42 carriers, among whom 30 were cancer-free, and 68 controls) underwent an ovarian reserve evaluation. Spontaneous fertility analysis included all women who previously attempted to become pregnant (134 women). We observed a tendency towards a premature decrease in ovarian reserve in BRCA1/2 pathogenic variant carriers, but no difference in mean AMH or AFC levels was found between BRCA1/2 pathogenic variant carriers and controls. An analysis of the extreme levels of AMH (≤5 pmol/l) and AFC (≤7 follicles) by logistic regression suggested a higher risk of low ovarian reserve among BRCA1/2 pathogenic variant carriers (adjusted odds ratio (OR) = 3.57, 95% CI = 1.00–12.8, p = 0.05; and adjusted OR = 4.99, 95% CI = 1.10–22.62, p = 0.04, respectively). Discussion Attention should be paid to BRCA1/2 pathogenic variant carriers’ ovarian reserve, considering this potential risk of premature alteration. A tendency towards a premature decrease in the ovarian reserve in BRCA1/2 pathogenic variant carriers was found. BRCA1/2 pathogenic variant carriers presented a higher risk of a low ovarian reserve. Information and education regarding reproduction is mandatory among BRCA1/2 pathogenic variant carriers.

Abstract
This study aimed to study whether IVF stimulation that results in one or two mature follicles should proceed to oocyte retrieval. This is a retrospective cohort study conducted at McGill University Health Center on 459 patients who underwent IVF treatment between 2011 and 2014, undergoing hormonal stimulation and monitoring of their ovarian response. The primary outcomes were pregnancy and live birth rates. Statistical modeling was used to determine individual roles of patient age and ovarian reserve on outcomes, while controlling for the other factors. Of the 459 cycles included in the study, 360 cycles (78.4%) ended in embryo transfer. Live birth rates per cycle were 15.6%, for the ≤ 34-year-olds; 6.5%, for the 35-39-year-olds; and 2.7%, for the ≥ 40-year-olds (p < 0.01). Twenty-five percent of the cycles in the ≥ 40-year-old group were canceled versus 17% and 15% in the 35-39-year-old and ≤ 34-year-old groups, respectively (p < 0.05). Testing likelihood of live birth as a function of age and antral follicular count (AFC) revealed that a 1-year increase in age reduces the likelihood of live birth by 11% (p < 0.05) and one-unit increase in AFC count leads to a 9% increase in the odds of a live birth (p < 0.05). For the youngest age group, the AFC had a most significant effect, and those with AFC > 11 had 56% live birth rate, while those with AFC ≤ 11 had only 6% of live birth rate. This study supports a shift in reasoning from age being the predictor of outcomes in women with a low response at IVF to both age and ovarian reserve needing to be taken into consideration.

Abstract
Air pollution has been an important risk factor for female reproductive health. However, epidemiological evidence of ambient air pollution on the predictor for ovarian reserve (antral follicle count, AFC) is deficient. We aim to comprehensively evaluate the association of long-term exposure to ambient air pollution with AFC among women of reproductive age in Shanxi of north China. 600 women with spontaneous menstrual cycle, not using controlled ovarian stimulation, were enrolled in the retrospective study. Two distinct periods of antral follicle development were designed as exposure windows. Generalized linear model was employed to estimate the change of AFC associated with exposure of atmospheric pollutants (SO2, NO2, PM10, PM2.5, CO and O3). Stratification analysis based on age (<30, ≥30 years), university degree (yes, no), years of exposure (2013-2016, 2017-2019) and duration of infertility (<2, 2-5, >5 years) along with two pollutants model were employed to further illustrate the association. We found every 10 μg/m3 increase in SO2 concentration level during the entire development stage of antral follicle was associated with a -0.01 change in AFC (95% confidence interval: -0.016, -0.002) adjusting for the confounders including age, BMI, parity and infertility diagnosis factors. The significant association of increased SO2 level with decreased AFC was particularly observed during the early transition from primary follicle to preantral follicle stage by 10 μg/m3 increase in SO2 exposure level with a -0.01 change (95% CI: -0.015, -0.002) in AFC. The negative association was pronounced among women aged ≥30 years old, and also significant in two pollutants model after adjusting the confounders. No significant associations between other air pollutants and AFC were observed. Our finding suggests that long-term exposure to air pollutant SO2 is associated with lower AFC, raising our concern that atmospheric SO2 exposure may have potential adverse impact on women ovarian reserve.

Abstract
Background The ovarian function and therefore the ovarian reserve may be compromised by the pathogenesis of autoimmune diseases of which, Hashimoto’s thyroiditis (HT) is the most common in women of reproductive age. Furthermore, a prolonged reduction in thyroid hormone concentration results in a broad spectrum of reproductive alteration. Previous reports in the literature have been controversial regarding the impact of hypothyroidism and alterations in the ovarian reserve. Thus, this prospective and comparative study aimed to evaluate the association of hypothyroidism with low ovarian reserve. Materials and Methods A subset of 27 patients with primary autoimmune hypothyroidism were compared to healthy women. The ovarian reserve was assessed through the anti-Mullerian hormone (AMH) and the antral follicle count (AFC). Results Overall, the two groups did not display significant differences in length of their menstrual cycles neither in the AMH serum levels nor the AFC. Conclusions No significant alteration was found in the ovarian reserve of women with HT.

Abstract
STUDY OBJECTIVE To compare the effects of ultrasound-guided aspiration and ethanol sclerotherapy with those of laparoscopic surgery on anti-Müllerian hormone (AMH) levels and ovarian reserve in benign-appearing ovarian endometrioma. DESIGN A prospective, cohort pilot study. SETTING Multiple centers, Spain. PATIENTS Forty patients with a suspected ovarian endometrioma with a maximum diameter of 35-100 mm. Serum hormonal concentrations were analyzed in 26 of these women. INTERVENTIONS Two groups: one that received US-guided aspiration plus alcohol sclerotherapy (n = 16) and the other that underwent laparoscopic cystectomy (n = 10). MEASUREMENTS AND MAIN RESULTS We studied serum hormonal concentrations (AMH, FSH and 17-β-estradiol) and antral follicle counts (AFC) in each patient at baseline, and after the procedures and pregnancies. No differences were found when comparing AMH and FSH concentrations before and after each procedure. 17-β-estradiol concentrations were significantly increased after alcohol sclerotherapy (p < 0.001). AFC recovery after 6 months seemed to be higher after sclerotherapy than after surgery. Three patients became pregnant in the sclerotherapy group. CONCLUSION This pilot study indicated that alcohol sclerotherapy preserves fertility in patients with endometriomas better than surgery, with significant increases in serum estradiol concentrations, possible AFC recovery and spontaneous pregnancies observed in the patients after sclerotherapy.

Abstract
RESEARCH QUESTION What is the association between serum anti-Müllerian hormone (AMH) concentrations and the number of utilizable embryos obtained per stimulation cycle of IVF/intracytoplasmic sperm injection (ICSI) in POSEIDON Groups 3 and 4? DESIGN Retrospective cohort study of 412 cycles, in which patients in POSEIDON Groups 3 and 4 (antral follicle count [AFC] ≤5 and AMH <1.2 ng/ml) underwent complete IVF/ICSI treatment cycles in the Reproductive Center of the First Affiliated Hospital of Xinjiang Medical University between January 2017 and March 2019. Patients underwent IVF/ICSI treatment using either progestin-primed ovarian stimulation (PPOS) or gonadotrophin-releasing hormone (GnRH) antagonist protocol as ovarian stimulation protocol. RESULTS Three models were established to analyse the correlation between AMH and the number of utilizable embryos in this study. After adjusting for covariates (age, baseline FSH, stimulation protocol and AFC), the number of embryos increased by 0.1 (95% confidence interval [CI] 0.06-0.14) with each increment of 0.1 ng/ml in AMH concentration. AMH was transformed from a continuous variable to a categorical variable (through trisection of AMH concentrations) and for the sensitivity analysis it was found that the number of embryos in the high AMH group (0.52-1.19 ng/ml) was 0.62 (95% CI 0.37-0.97) higher than in the low AMH group (0.06-0.24 ng/ml). CONCLUSIONS High AMH in patients in POSEIDON Groups 3 and 4 was found to be associated with an increase in the number of available embryos in IVF/ICSI. The potential reproductive prognosis can be assessed by AMH, to reduce the abandonment of treatment due to underestimation or to implement multiple ineffective stimulation cycles of treatment.

Abstract
PURPOSE The aim of this study was to determine the autoimmune effects of ankylosing spondylitis (AS) on the fertility potential of women by evaluating ovarian reserves of AS patients. METHODS A total of 104 patients, 52 in the AS group (study group) and 52 in the control group were included in the study. Ovarian reserve was evaluated by serum anti-Müllerian hormone (AMH) levels, antral follicle count (AFC) and baseline serum follicle-stimulating hormone (FSH) levels. RESULTS The mean serum AMH levels were significantly lower in the study group when compared to the controls (2.203 ± 1.110 vs. 1.188 ± 0.891, p < 0.001). In addition, the mean AFC was also significantly lower in the study group. (10.67 ± 1.81 vs. 9.54 ± 2.50, p = 0.009). Mean FSH levels were calculated to be 6.72 ± 1.14 in the study group and 7.21 ± 1.22 in the control group. The difference was not statistically significant (p = 0.781). CONCLUSION This study shows that AS like several other autoimmune conditions has an adverse effect on the female fertility potential. Therefore, an early start and long-term management of AS patients who have fertility desire is recommended. Serum AMH levels can be used in monitoring ovarian reserve and in early detection of reproductive decline of AS patients. CLINICALTRIAL NUMBER NCT04209881.

Abstract
Studies suggest that the presence of endometriosis may lead to impaired ovarian reserve, while results evaluating the changes in antral follicle count (AFC) in endometriosis remain controversial. A systematic search returned 15 studies, of which nine compared AFC between patients with and without endometriosis, five articles reported differences in AFC between affected and unaffected ovaries in patients with unilateral ovarian endometriosis and one reported both of the above two situations. Overall results showed a significant decrease in AFC and anti-Müllerian hormone (AMH) and increase in serum FSH concentrations in patients with endometriosis when compared with controls. Additionally, the AFC for the ovary with the endometrioma was also significantly lower than that of the contralateral ovary in patients with unilateral ovarian endometriosis. Moreover, it appears that the AFC in patients with endometriosis where the ovaries are not affected or in early stage were not significantly different in the control group. These findings demonstrate that endometriosis is associated with reduced AFC and AMH and elevated serum concentrations of FSH, suggesting a reduction in ovarian reserve in patients with endometriosis, especially in those with ovarian endometrioma and advanced stage.

Abstract
In the present study, there was an evaluation of in vitro embryo production (IVEP) in Bos indicus donor cows with small or large antral follicle counts (AFCs) when there was synchronization of follicular dynamics among cows before ovum pick-up (OPU). Donor cows classified as having small or large AFC were submitted to OPU/IVEP program (Experiment-I) or had follicular-stage synchronization imposed before OPU/IVEP (Experiment-II). In Experiment-I, the cows with a large AFC had a greater (P < 0.01) mean of embryos developing to the blastocyst stage compared to those with a small AFC. In Experiment-II, percentage of viable oocytes/OPU were not affected (P = 0.33) by synchronization of follicular dynamics, but the AFC had an effect (P < 0.0001). There was an interaction (P = 0.01) indicating the larger AFC, with or without imposing of a synchronization treatment regimen, resulted in the most desirable outcome. The number of embryos was affected (P < 0.001) by follicular-stage synchronization and AFC, with there being an interaction (P = 0.002) with the most desirable results for the large AFC-synchronized group. Number of pregnancies was greater (P ≤ 0.02) for recipient females with embryos from synchronized donors and with a large AFC. There was an interaction (P = 0.03) with there being a greater pregnancy percentage for cows with synchronized follicular stages and the large AFC. Bos indicus donor with a large AFC when associated with the synchronization of stage of follicular dynamics pre-OPU results in improvement of the efficacy of IVEP.

Abstract
BACKGROUND To determine if a modified ovarian sensitivity index (MOSI), based on initial follicular measurements and the initial follicle-stimulating hormone (FSH) dose, can predict the production of high-quality embryos for successful implantation during in vitro fertilization (IVF). METHODS This study consisted of two phases: 1) a retrospective study and 2) a prospective observational study. For the first phase, 363 patients charts were reviewed, of which 283 had embryos transferred. All women underwent a standardized antagonist-based IVF protocol. At the first follow-up (Day 3/4), the number and size of the follicles were determined. MOSI was calculated as ln (number follicles (≥6 mm) × 1000 / FSH initial dose). Afterward, the number and quality of the ova, embryo development, and the number and quality of the blastocysts were determined. Embryo implantation was confirmed by β-hCG. For the second phase, 337 IVF cycles were followed to determine MOSI's accuracy. RESULTS MOSI could predict the production of ≥4 high-quality embryos by Day 2 (AUC = 0.69, 95%CI:0.63-0.75), ≥2 blastocysts (AUC = 0.74, 95%CI:0.68-0.79), and ≥ 35% rate of blastocyst formation (AUC = 0.65, 95%CI:0.58-0.72). Using linear regression, MOSI was highly associated with the number of ova captured (β = 5.15), MII oocytes (β = 4.31), embryos produced (β = 2.90), high-quality embryos (β = 0.98), and the blastocyst formation rate (β = 0.06, p < 0.01). Using logistic regression, MOSI was highly associated with achieving ≥4 high-quality embryos (odds ratio = 2.80, 95%CI:1.90-4.13), ≥2 blastocysts (odds ratio = 3.40, 95%CI:2.33-4.95), and ≥ 35% blastocysts formation rate (odds ratio = 1.96, 95%CI:1.31-2.92). This effect was independent of age, BMI, and antral follicle count. For implantation, MOSI was significantly associated with successful implantation (odds ratio = 1.79, 95%CI:1.25-2.57). For the prospective study, MOSI was highly accurate at predicting ≥6 high-quality embryos on Day 2 (accuracy = 68.5%), ≥6 blastocysts (accuracy = 68.0%), and a blastocyst formation rate of ≥35% (accuracy = 61.4%). CONCLUSION MOSI was highly correlated with key IVF parameters that are associated with achieved pregnancy. Using this index with antagonist cycles, clinicians may opt to stop an IVF cycle, under the assumption that the cycle will fail to produce good blastocysts, preventing wasting the patient's resources and time.

Abstract
OBJECTIVE To investigate the associations between dietary patterns and antral follicle count (AFC), a marker of ovarian reserve. DESIGN Prospective cohort study. SETTING Fertility center at an academic hospital. PATIENT(S) A total of 363 women seeking preconception evaluation and infertility care at the Massachusetts General Hospital who participated in the Environment and Reproductive Health Study. INTERVENTION(S) None. At enrollment, women reported diet through a food frequency questionnaire, from which we computed three dietary pattern adherence scores: the Mediterranean diet, the Fertility diet, and the Profertility diet. MAIN OUTCOME MEASURE(S) The AFC was assessed with a transvaginal ultrasound performed on the third day of an unstimulated menstrual cycle or on the third day of a P withdrawal bleed. RESULT(S) Higher adherence to the three dietary patterns examined were unrelated to AFC. The multivariable adjusted AFC means and 95% confidence intervals for women in the highest compared with the lowest quartile of adherence score were 13.9 (13.0-14.9) and 13.5 (12.6-14.4) for the Mediterranean diet, 14.0 (13.2-14.9) and 13.5 (12.7-14.3) for the Fertility diet, and 12.5 (11.6-13.5) and 13.3 (12.5-14.2) for the Profertility diet. CONCLUSION(S) Dietary patterns were unrelated to AFC among a cohort of women presenting at a fertility center. Due to the limited and heterogeneous current evidence, it is important to evaluate this association in further studies, and in particular among women from the general population.

Abstract
Purpose Problems with fallopian tubes are one of the main reasons for women to undergo in vitro fertilization-embryo transfer (IVF-ET). A large proportion of women with ectopic pregnancy, fallopian tube obstruction and hydrosalpinx have had one or both fallopian tubes removed by salpingectomy. With increasing age, ovarian reserve deteriorates, the numbers of retrieved oocytes, available embryos and high-quality embryos are reduced, and the live birth rate for women treated with IVF treatment is affected. Thus, it is important to understand how salpingectomy affects live birth rates for IVF patients of different ages. This study analyzed how patients’ age and salpingectomy influenced ovarian reserve, ovarian response and pregnancy outcomes for infertile women undergoing IVF-ET. Methods A total of 1922 patients that underwent IVF-ET treatment from January 1, 2012, to December 31, 2018, were included in this retrospective study. The patients were divided into two groups according to whether or not they had a previous history of salpingectomy. The salpingectomy (group A, 534 patients) and control groups (group B, 1388 patients) were then further divided into two subgroups according to patient age (age<35 years, and age 35–39 years). Ovarian reserve, ovarian response, and IVF outcomes were investigated for each subgroup. Logistic regression model was used to estimate the relationship between clinical pregnancy and live births and patients’ baseline characteristics. Results In the salpingectomy group, antral follicle counts (AFC) were significantly lower for the subgroup aged 35 to 39 years compared with the control group. But this difference did not appear in women younger than 35 years. In addition, there were no significant differences in levels of basal follicle stimulation hormone (FSH), basal luteinizing hormone (LH), basal estradiol (E2), total gonadotropins (Gn) dose, duration of Gn, numbers of retrieved oocytes, fertilization rates, numbers of available embryos, live birth rates, clinical pregnancy rates, miscarriage rates, ectopic pregnancy rates, or multiple pregnancy rates between the salpingectomy group and the control group (P > 0.05). Age is a risk factor for the clinical pregnancy and live birth. Conclusion Salpingectomy may decrease antral follicle count but not live birth rate for IVF-ET patients aged 35–39 years. The increased female age was negative related with clinical pregnancy and live birth.

Abstract
Both 2-D and 3-D transvaginal ultrasonography are effective imaging modalities for assessment of ovarian reserve. Our aim was to compare both modalities in assessment of ovarian reserve of women undergoing in vitro fertilization/intra-cytoplasmic sperm injection (IVF/ICSI). Fifty women were scheduled according to their menstrual cycle to be examined by both 2-D and 3-D transvaginal ultrasonography. We found that the average time for computerized analysis of the 3-D ultrasound data was significantly shorter than that for analysis of the 2-D ultrasound data, for both total antral follicle count and ovarian volume. However, there were no statistically significant differences between the methods in total antral follicle count and ovarian volume. We conclude that, where available, 3-D ultrasonography can be used for assessment of ovarian reserve in addition to the biochemical marker, particularly in overcrowded in vitro fertilization centers that need to save time.

Abstract
In organ or non-organ-specific autoimmune disorders, human ovary is usually the target of the autoimmune attack. We aimed to demonstrate the correlation between ovarian reserve and DM1, based on the view that women with type-1 diabetes mellitus (DM1) will have lower AMH levels secondary to poor glycemic control and autoimmune attacks. Ovarian functions of 42 patients diagnosed with DM1 who use insulin and 65 healthy volunteers were analyzed. Basal hormone and AMH levels were measured during the follicular phase. Fasting and postprandial blood glucose concentrations, HbA1c and C-peptide levels were evaluated. The mean antral follicle count (AFC) was significantly lower in DM1 patients than in healthy controls (p = .001). The AMH levels were lower in women with DM1 than in the controls (p = .001). The HbA1c values of DM1 patients, who formed the study group, was significantly higher than the control group. Ovarian reserve that is evaluated with serum AMH level is affected by poor glycemic control in type 1 diabetes. Due to the time of the autoimmune damage in the ovaries and the observable effects of this damage, more comprehensive and longer-term studies are needed to be conducted for the follow-up of reproductive abnormalities.

Abstract
RESEARCH QUESTION Does the presence of ovarian endometriomas affect ovarian response to ovarian stimulation after adjusting for age and ovarian reserve markers? DESIGN This retrospective cross-sectional study compared the ovarian response between patients with ovarian endometriomas and women with other infertility factors undergoing their first ovarian stimulation for IVF/intracytoplasmic sperm injection (ICSI). An age-specific nomogram model for the number of oocytes retrieved was built for both groups, and ovarian response was compared after adjusting for age, gonadotrophin dose, anti-Mullerian hormone (AMH) concentration and antral follicle count (AFC). RESULTS A total of 923 patients were included: 101 women with at least one ovarian endometrioma, and 822 patients with other infertility factors. Comparisons of the nomograms for the number of oocytes retrieved demonstrated that response was significantly lower for women with endometrioma when the results were adjusted for age the z-score for the number of oocytes retrieved (-0.49 ± 0.71 versus -0.20 ± 0.86; 95% confidence interval [CI] -0.47 to -0.12) and also after adjustment for the total dose of gonadotrophins and AMH values (z-score mean difference -0.338; 95% CI -0.54, -0.14). When the z-score was adjusted for gonadotrophin dose and AFC, the number of oocytes retrieved was comparable between the two groups (z-score mean difference -0.038; 95% CI -0.34 to 0.27). CONCLUSIONS Ovarian response after ovarian stimulation for IVF/ICSI in women with endometriomas is significantly lower than in controls after adjusting for age, gonadotrophin dose and AMH. Dose and protocol selection for ovarian stimulation in patients with endometrioma should be based on AFC rather than AMH, as the latter may be overestimated.

Abstract
It was hypothesized that Brahman cows have greater in vitro embryo production than Simmental cows, and that regardless of breed, antral follicle count (AFC) and vulvar width (VW) are positively associated with oocyte quality, embryo number and pregnancy rate. Brahman (Bos taurus indicus, n = 184) and Simmental (Bos taurus taurus, n = 99) cows were classified as having a large AFC (Brahman: ≥50, Simmental: ≥25); intermediate AFC (Brahman: >30 and ≤49; Simmental: >16 and <24) and small AFC (Brahman: <30, Simmental: ≤15). The VW was considered to be large (Brahman: >123 mm, Simmental: >80 mm); intermediate (Brahman: >102 mm and ≤123 mm; Simmental: >65 mm and ≤80 mm) and small (Brahman: ≤102 mm and Simmental: ≤65 mm). For each group of cows, ovum pick up, oocyte in vitro maturation, fertilization and embryo culture were performed. Embryo transfers were subsequently performed and pregnancy rate was evaluated. Brahman cows had a larger number of viable oocytes, greater efficiency of embryo production and greater pregnancy rate (P < 0.05) than Simmental cows. Pregnancy percentages in Simmental cows with a small AFC were greater than those cows with an intermediate and large AFC. With the Brahman cows, there was no difference in pregnancy rate among the cows with different AFC classifications. In contrast to Simmental cows, Brahman cows with an intermediate VW had a greater pregnancy percentage than those with a small and large AFC. In conclusion, Brahman cows have a larger AFC, number of viable oocytes, and pregnancy rate than Simmental cows.

Abstract
PURPOSE This study sought to evaluate the prevalence of menopausal symptoms in a population of reproductive-aged women remote from cancer therapy compared with a group of healthy similar-aged controls and with a cohort of late reproductive-aged (LR) controls. METHODS Participants were assessed for symptoms of menopause, early follicular phase hormones, and ultrasound examinations. Menopausal symptoms were analyzed in exposed participants and controls using χ2 analyses, Wilcoxon-Mann Whitney tests, and multivariable logistic regression models. RESULTS One hundred seventy cancer survivors, 135 similar-aged controls, and 71 LR controls were followed prospectively for an average of 38 months. Compared with similar-aged controls, a greater proportion of survivors reported vasomotor symptoms at some point over the study period (35% vs 19%, p < 0.01), and this proportion was similar to LR controls (44%, p = 0.22). Survivors were more likely to be bothered by vaginal dryness (27%) than similar-aged controls (16%, p = 0.02) or LR controls (14%, p = 0.02). FSH levels were 38.4% higher in those with vasomotor symptoms compared with those without symptoms (p = 0.021). CONCLUSIONS Reproductive-aged cancer survivors have a higher prevalence of vasomotor symptoms and vaginal dryness than their similar-aged peers. IMPLICATIONS FOR CANCER SURVIVORS Providers should be attuned to the high prevalence of menopausal symptoms in cancer survivors.

Abstract
Objective: To compare the effects of laparoscopic cystectomy on ovarian reserve between women with endometrioma and dermoid cyst. Materials and Methods: Thirty-six patients were diagnosed as having endometrioma (group A) and 32 patients with dermoid cyst (group B) using ultrasonography. Preoperative anti-mullerian hormone (AMH) levels were measured and unilateral antral follicle counts (AFC) were calculated for the ovary side containing the cyst. Laparoscopic cystectomy was performed using the stripping technique for all participants. After 3 months, all participants were re-evaluated between the third and sixth day of their menstrual cycle to determine AFC and AMH levels. Results: The mean serum preoperative AMH level and AFC level were significantly lower in group A than in group B (p=0.001, p=0.002), respectively. At 3 months after the surgery, serum AMH levels decreased significantly in group A from 2.04±0.68 to 1.47±0.55 (p=0.001), and from 2.60±0.57 to 2.17±0.56 in group B (p=0.001). In group A, unilateral (operated side) AFC levels decreased significantly from 4.05±1.24 to 2.16±0.94 (p=0.001), and in group B, it decreased significantly from 4.93±0.94 to 3.40±0.87 (p=0.001). The decrease in AMH levels was significantly higher in group A than in group B (p=0.033). The decrease in AFC levels was also significantly higher in group A than in group B (p=0.044). Conclusion: Laparoscopic stripping has destructive effects on serum AMH levels and the operated side AFC levels after surgery for patients with endometrioma and dermoid cysts, and laparoscopic excision of endometrioma has more destructive effects on ovarian reserve than dermoid cysts.

Abstract
BACKGROUND The timing of the first postpartum ovulation is an important factor affecting the timing of estrous resumption in dairy cows. The first postpartum ovulation is delayed in cows producing large amounts of milk with an intensive negative energy balance. The antral follicle count (AFC) and serum anti-Müllerian hormone concentrations are known to be indicators of the ovarian reserve, which is the number and quality of follicles left in a pair of ovaries and known as an indicator of female fertility. Cows with higher AFC have been proven to show higher pregnancy rate and shorter calving to conception intervals; however, the relationship between the timing of the first postpartum ovulation and ovarian reserve remains unclear. Therefore, this study examined the relationships between postpartum follicular dynamics, the ovarian cycle, nutritional status, and ovarian reserve. METHODS Transrectal ultrasonography was conducted from calving to 70-120 days in milk (DIM) in 26 cows to monitor AFC, follicular dynamics and the ovarian cycle. Body weight (BW) and milk yield were used as indicators of nutritional status. RESULTS The first postpartum ovulation was significantly later in cows with low AFC (< 25) than in those with high AFC (≥25), while changes in BW from calving to the nadir and milk production were similar in both groups. The present results also suggested that cows with low AFC and a delayed first postpartum ovulation had a shorter first ovarian cycle after the first postpartum ovulation. The mean DIM of the first postpartum artificial insemination (AI) and days open (days from calving to AI with which pregnancy was achieved) were similar in high and low AFC groups. CONCLUSIONS The first postpartum ovulation was significantly earlier in cows with high AFC than in those with low AFC. The assumed reason for this result was higher sensitivity to luteinizing hormone and larger androstenedione and estradiol production in follicles in high AFC cows. Therefore, cows with high AFC may be more fertile than those with low AFC while their milk production increase and BW decrease; it means they are in negative energy balance. (340/350 words).

Abstract
Objective The aim of this study was to establish whether differences in ovarian size exist between the right and the left ovary of the same individual in women with polycystic ovary syndrome. Methods In total, 206 Korean women with polycystic ovary syndrome were included in this study. In all participants, a transvaginal or transrectal ultrasound examination was conducted in the early follicular phase of the menstrual cycle. Results A significant linear correlation was found between the two ovaries with regard to antral follicle count and ovarian volume. The mean antral follicle count in the right ovary (26.75±11.72) was significantly higher than that in the left ovary (23.98±10.85), and the mean volume of the right ovary (11.06±5.17 cm3) was significantly different from that of the left ovary (9.12±4.89 cm3). Conclusion Ovarian size is different between the right and the left ovary in women with polycystic ovary syndrome.

Abstract
BACKGROUND The antral follicle count (AFC) in mammalian ovaries positively correlates with female fertility. To clarify the causes of differences in fertility between low and high AFC cows, we investigated follicular growth dynamics and hormone concentrations in plasma, follicular fluid, and in vitro growth (IVG) media at different stages of follicular growth. METHODS Seven cows were divided into high AFC (n = 4, > 30 follicles) and low AFC (n = 3, < 30 follicles) groups based on the peak AFC detected by ultrasonography. These cows were subjected to estrous synchronization, daily ovarian ultrasonography, and blood collection. Their follicular fluid was collected from dominant follicles at different stages (selection, luteal, and ovulatory phases). In another experiment, we cultured oocyte-cumulus-granulosa cell complexes collected from early antral follicles (< 1 mm) for 12 days. Estradiol-17β (E2), testosterone (T), progesterone (P4), and anti-Müllerian hormone (AMH) concentrations in follicular fluids and plasma were measured. Plasma follicle-stimulating hormone (FSH) concentrations were examined. E2, P4, and AMH concentrations were also measured in IVG media. RESULTS The numbers of small (< 4 mm) and intermediate (4-8 mm) follicles were larger in the high AFC group than in the low AFC group (P < 0.05). The number of intermediate follicles was stable in the low AFC group, indicating consistent development. However, the number of these follicles fluctuated in the high AFC group. Plasma FSH concentrations were higher, whereas E2 and T concentrations were lower in the low AFC group (P < 0.05). E2 concentrations and the E2/P4 ratio in ovulatory follicles and IVG media on day 8 were higher in the high AFC group (P < 0.05). AMH concentrations in plasma and IVG media (P < 0.01) were higher in the high AFC group. CONCLUSIONS The weaker response to FSH of granulosa cells caused low E2 production in the low AFC group, resulting in high FSH concentrations and the consistent development of intermediate follicles. Conversely, higher E2 concentrations suppressed FSH secretion in the high AFC group. Granulosa cells in the high AFC group had the ability to produce more AMH than those in the low AFC group throughout IVG culture.

Abstract
Background The incidence of Cesarean has increased in recent years. The purpose of this study is to evaluate the effect of cesarean section on ovarian reserve. This is a prospective cohort study from January 2016 to November 2017. Inclusion criteria included singleton primigravid pregnant women whose gestational age was above 37 weeks. Exclusion criteria included history of infertility, pelvic surgery, underlying chronic diseases, any adverse pregnancy outcome and postpartum complication in current pregnancy and hormonal medication within six months of delivery. Anti-Mullerian hormone was measured at the admission time for delivery. The type of delivery was determined based on obstetrics indications. Six months after delivery, antral follicle count was performed and anti-Mullerian hormone was measured again. Result(s) First blood sample was taken from 730 women. After excluding 550 women, the second blood sample was taken from 180 participants. The mean of first anti-Mullerian hormone in women with cesarean and vaginal delivery were 1.01 ng/mL (95% CI 0.82 to 1.18) and 1.18 ng/mL (95% CI 0.96 to 1.40) respectively (P = 0.211). The mean of second anti-Mullerian hormone in women with cesarean and vaginal delivery were 4.77 ng/mL (95% CI:3.91 to 5.63) and 4.92 ng/mL (95% CI: 4.01 to 5.82) respectively (P = 0.818). No statistically significant difference existed in total AFC between cesarean and vaginal delivery groups (MD: 0.41, 95% CI: − 1.05 to 1.89, P = 0.576). Conclusion Antral follicle count and anti-Mullerian hormone, six month after delivery, are not affected by delivery mode even after adjusting for women’s age, baseline Anti-Mullerian hormone, body mass index, gestational age at delivery, breastfeeding, postpartum menstruation, neonatal sex and weight. Based on our best knowledge, this is the first report that investigates the effects of delivery mode on ovarian reserve. Decreased fertility following cesarean has been shown in some previous studies but most of them had assessed this association based on the incidence of subsequent pregnancy. Since subsequent pregnancy can be influenced by several confounding factors, we investigated the effect of cesarean on fertility using its impact on anti-Mullerian hormone levels and antral follicle count. We hope that this study will be a beginning of more detailed studies in this field. We believe that this link is yet to be studied.

Abstract
The objective of the current analysis was to investigate the associations of urinary triclosan concentrations with parameters of ovarian reserve. Five hundred eleven female aged 25-39 years who attended the infertility clinic for diagnostic purposes were recruited. Urinary concentrations of triclosan were measured by a validated gas chromatograohy ion-tap mass spectrometry method. Parameters of ovarian reserve were: antral follicle count (AFC), anti-Müllerian hormone (AMH), follicle-stimulating hormone (FSH) and estradiol (E2) levels. Urinary concentrations of triclosan decrease antral follicle count. There were no statistically significant associations between other parameters of ovarian reserve (estradiol, FSH and AMH levels) and triclosan concentrations. Triclosan exposure may negatively affect antral follicle count, a marker of ovarian reserve. As the data on triclosan exposure and ovarian reserve are scarce additional study is needed to confirm the results.

Abstract
BACKGROUND In general, anti-Müllerian hormone (AMH) is positively associated with antral follicle count (AFC). However, there is often discordance between the AMH level and AFC in clinical practice. In cases of discordance, which indicator should be chosen to predict ovarian response and subsequently develop an ovulation induction protocol? The objective of this study was to investigate which indicator was more accurate in predicting ovarian response and pregnancy outcomes when the AMH level and AFC were discordant. METHODS A total of 1121 infertile women undergoing IVF/ICSI were recruited in this study. During the study period, patients were subjected to individualized controlled ovarian hyperstimulation (COH) protocols according to specific characteristics. The AMH levels and AFCs were measured on days 2-3 of the menstrual cycle. Serum samples were obtained to determine AMH levels. Transvaginal ultrasound was performed to determine the AFC. All patients were divided into four groups: Group A had AFCs and AMH levels in the normal range; Group B had normal AFCs and low AMH levels; Group C had low AFCs and normal AMH levels; and Group D had low AFCs and AMH levels. RESULTS Two hundred three women (18.11%) showed discordant AFCs and AMH levels. In the two groups with discordant AFCs and AMH levels, namely, Group B and Group C, the oocyte yield, good-quality embryo rate and clinical pregnancy rate were significantly higher in Group B than in Group C. The incidence of poor ovarian response (POR) was significantly lower in Group B than in Group C. According to the stratified analysis of age, for the three categories above the age of 30, oocyte yield was higher in Group B than in Group C. In all age categories, the clinical pregnancy rate was higher in Group B than in Group C.

In view of the AFC being better than AMH for predicting POR, the AFC should be the preferred indicator for predicting ovarian response to subsequently develop an optimal individualized COH protocol.
