ABSTRACT
The Phylum Cressdnaviricota consists of a large number of circular Rep-encoding single-stranded (CRESS)-DNA viruses. Recently, metagenomic analyzes revealed their ubiquitous distribution in a diverse range of eukaryotes. Data relating to CRESS-DNA viruses in humans remains scarce. Our study investigated the presence and genetic diversity of CRESS-DNA viruses in human vaginal secretions. Vaginal swabs were collected from 28 women between 29 and 43 years old attending a fertility clinic in New York City. An exploratory metagenomic analysis was performed and detection of CRESS-DNA viruses was confirmed through analysis of near full-length sequences of the viral isolates. A phylogenetic tree was based on the REP open reading frame sequences of the CRESS-DNA virus genome. Eleven nearly complete CRESS-DNA viral genomes were identified in 16 (57.1%) women. There were no associations between the presence of these viruses and any demographic or clinical parameters. Phylogenetic analysis indicated that one of the sequences belonged to the genus Gemycircularvirus within the Genomoviridae family, while ten sequences represented previously unclassified species of CRESS-DNA viruses. Novel species of CRESS-DNA viruses are present in the vaginal tract of adult women. Although they be transient commensal agents, the potential clinical implications for their presence at this site cannot be dismissed.

PROBLEM: The association of viruses with infertility remains incompletely evaluated. METHOD OF STUDY: Vaginal secretions from 46 women seeking treatment in the Center for Reproductive Medicine and Infertility at Weill Cornell Medicine were tested for viruses by metagenomic analysis by lab personnel blinded to all clinical data. RESULTS: Torquetenovirus (TTV) was identified in 16 women, alphapapillomavirus in seven women and most were positive for bacteriophages. Twelve of the subjects were fertile and sought to freeze their oocytes for future implantation. These women were all negative for TTV. In contrast, 16 of the 34 women (47.1%) being treated for infertility were TTV-positive (p = .0035). Evaluating the women by cause of infertility, five of nine women (55.6%) whose male partner had inadequate sperm parameters and six of 14 women (42.9%) with defective ovulation were TTV positive (p = .0062 and p = .0171, respectively, vs. the fertile women). Alphapapillomavirus was identified in one (8.3%) fertile woman, five (35.7%) women with ovulation deficiency, and one (11.1%) woman with male factor infertility. These differences were not statistically significant. There were no differences in bacteriophage families or the presence of Lactobacillus phages between fertile or infertile women or between different causes of infertility. There was a negative association between TTV detection and Lactobacillus crispatus dominance in the vaginal microbiota (p = .0184), but no association between TTV detection and the presence of alphapapillomavirus or Candida species. CONCLUSION: Detection of TTV in the vagina might be a biomarker for specific causes of infertility.

OBJECTIVE: To determine whether peak estradiol (E2) levels above the usual physiologic range (300-500 pg/mL) will impact programmed frozen embryo transfer (FET) outcomes in an ideal study population of those using good-quality single euploid blastocysts. DESIGN: Retrospective cohort study. SETTING: University-based clinic. PATIENTS: Single euploid-programmed FET done at a single academic institution from January 2016 to December 2019. The population was divided into three groups on the basis of peak serum E2 levels during endometrial preparation: group A (E2 <300 pg/mL), group B (300-500 pg/mL), and group C (>500 pg/mL). Group B was used as the reference range for statistical analysis. INTERVENTION: Frozen embryo transfer cycles. MAIN OUTCOME MEASURES: The primary outcome was the live birth rate (LBR). Secondary outcomes included implantation, biochemical, ectopic, and miscarriage rates. RESULTS: A total of 750 FET cycles were included in this study. Poisson regression analysis showed a negative impact of higher peak E2 on the LBR. A decrease in LBR was noted between group C and referent group B (50.2% vs. 63.4%, risk ratio 0.79 [0.68-0.91]) and group A and referent group B (42.5% vs. 63.4%, risk ratio 0.67 [0.46-0.98]). Secondary outcomes were notable for a lower implantation rate when groups A and C were compared with group B and a higher biochemical rate between group C and group B. There was no notable difference between groups in ectopic or miscarriage rates. CONCLUSION: Limiting peak serum E2 levels to 300-500 pg/mL during programmed FET cycles is associated with improved LBRs compared with cycles with peak E2 levels of <300 pg/mL or >500 pg/mL in an ideal study population.

BACKGROUND: Approximately 15% of all clinically recognized pregnancies in patients with infertility result in spontaneous abortion. However, despite its potential to have a profound and lasting effect on physical and emotional well-being, the natural history of spontaneous abortion in women with infertility has not been described. Although vaginal bleeding is a common symptom in pregnancies conceived via reproductive technologies, its prognostic value is not well understood. OBJECTIVE: This study aimed to evaluate the combination of early pregnancy bleeding and first-trimester ultrasound measurements to determine spontaneous abortion risk. STUDY DESIGN: This was a retrospective cohort study of patients with infertility who underwent autologous embryo transfer resulting in singleton intrauterine pregnancy confirmed by ultrasound from January 1, 2017, to December 31, 2019. Early pregnancy symptoms of bleeding occurring before gestational week 8 and measurements of crown-rump length and fetal heart rate from ultrasounds performed during gestational week 6 (6 0/7 to 6 6/7 weeks of gestation) and gestational week 7 (7 0/7 to 7 6/7 weeks of gestation) were recorded. Modified Poisson regression with robust error variance was adjusted a priori for patient age, embryo transfer day, and transfer of a preimplantation genetic-tested embryo to estimate the relative risk and 95% confidence interval of spontaneous abortion for dichotomous variables. The relative risks and positive predictive values for early pregnancy bleeding combined with ultrasound measurements on the occurrence of spontaneous abortion were calculated for patients who had an ultrasound performed during gestational week 6 and separately for patients who had an ultrasound performed during gestational week 7. The primary outcome was spontaneous abortion in the setting of vaginal bleeding with normal ultrasound parameters. The secondary outcomes were spontaneous abortion with vaginal bleeding and (1) abnormal crown-rump length, (2) abnormal fetal heart rate, and (3) both abnormal crown-rump length and abnormal fetal heart rate. RESULTS: Of the 1858 patients who were included (359 cases resulted in abortions and 1499 resulted in live births), 315 patients (17.0%) reported vaginal bleeding. When combined with ultrasound measurements from gestational week 6, bleeding was significantly associated with increased spontaneous abortion only when accompanied by absent fetal heart rate (relative risk, 5.36; 95% confidence interval, 3.36-8.55) or both absent fetal heart rate and absent fetal pole (relative risk, 9.67; 95% confidence interval, 7.45-12.56). Similarly, when combined with ultrasound measurements from gestational week 7, bleeding was significantly associated with increased spontaneous abortion only when accompanied by an abnormal assessment of fetal heart rate or crown-rump length (relative risk, 5.09; 95% confidence interval, 1.83-14.19) or both fetal heart rate and crown-rump length (relative risk, 14.82; 95% confidence interval, 10.54-20.83). With normal ultrasound measurements, bleeding was not associated with increased spontaneous abortion risk (relative risk: 1.05 [95% confidence interval, 0.61-1.78] in gestational week 6 and 0.80 [95% confidence interval, 0.36-1.74] in gestational week 7), and the live birth rate was comparable with that in patients with normal ultrasound measurements and no bleeding. CONCLUSION: Patients with a history of infertility who present after embryo transfer with symptoms of vaginal bleeding should be evaluated with a pregnancy ultrasound to accurately assess spontaneous abortion risk. In the setting of normal ultrasound measurements, patients can be reassured that their risk of spontaneous abortion is not increased and that their live birth rate is not decreased.

The study objectives were to determine whether ovarian morphology can distinguish between women with regular menstrual cycles, normo-androgenic anovulation (NA-Anov), and PCOS and whether body mass index (BMI)-specific thresholds improved diagnostic potential. Women with PCOS (biochemical and/or clinical hyperandrogenism and irregular cycles; N = 66), NA-Anov (irregular cycles without clinical and/or biochemical hyperandrogenism; N = 64), or regular cycles (controls; cycles every 21-35 days in the absence of clinical or biochemical hyperandrogenism; N = 51) were evaluated. Participants underwent a reproductive history, physical exam, transvaginal ultrasound, and a fasting blood sample. Linear regression analyses were used to assess the impact of BMI on ovarian morphology across groups. The diagnostic performance of ovarian morphology for anovulatory conditions, and by BMI (lean: <25 kg/m2; overweight: ≥25 kg/m2), was tested using Receiver Operating Characteristic (ROC) curves. Follicle number per ovary (FNPO) and ovarian volume (OV), but not follicle number per cross-section (FNPS), increased across controls, NA-Anov, and PCOS. Overall, FNPO had the best diagnostic performance for PCOS versus controls (AUCROC = 0.815) and NA-Anov and controls (AUCROC = 0.704), and OV to differentiate between PCOS and NA-Anov (AUCROC = 0.698). In lean women, FNPO best differentiated between PCOS and controls (AUCROC = 0.843) and PCOS versus NA-Anov (AUCROC = 0.710). FNPS better distinguished between NA-Anov and controls (AUCROC = 0.687), although diagnostic performance was lower than when thresholds were generated using all participants. In women with overweight and obesity, OV persisted as the best diagnostic feature across all analyses (PCOS versus control, AUCROC = 0.885; PCOS versus NA-Anov, AUCROC = 0.673; NA-Anov versus controls, AUCROC = 0.754). Ovarian morphology holds diagnostic potential to distinguish between NA-Anov and PCOS, with marginal differences in diagnostic potential when participants were stratified by BMI suggesting that follicle number may provide better diagnostic performance in lean women and ovarian size in those with overweight.
ABSTRACT
OBJECTIVE: To assess the association between antimüllerian hormone (AMH) and embryo ploidy rates in 2 cohorts of patients undergoing in vitro fertilization (IVF) with trophectoderm biopsy for preimplantation genetic testing for aneuploidy (PGT-A): the general population of women pursuing IVF with PGT-A (Infertile cohort) and women pursuing IVF with preimplantation genetic testing for monogenic disorders (PGT-M) owing to the risk of hereditary monogenic diseases (Non-infertile cohort). DESIGN: Retrospective cohort study. SETTING: Academic center. PATIENT(S): Patients undergoing their first cycle of IVF with trophectoderm biopsy and PGT-A or PGT-A and PGT-M in our center between March 2012 and June 2020. Patients of advanced maternal age according to the Bologna criteria (age ≥40 years) and patients who underwent fresh embryo transfers were excluded. INTERVENTION(S): None. MAIN OUTCOME MEASURE(S): Proportion of euploid, mosaic, and aneuploid embryos per cycle. RESULT(S): "Infertile" (n = 926) and "Non-infertile" (n = 214) patients were stratified on the basis of AMH levels, with low-AMH defined as <1.1 ng/mL in accordance with the Bologna criteria. Age-adjusted regression models showed no relationship between AMH classification and proportion of euploid, mosaic, and aneuploid embryos in the Infertile or Non-infertile cohorts. In the Infertile cohort, no association between AMH classification and embryo ploidy rates was identified in a subgroup analysis of patients aged <35 years, 35-37 years, and 38-39 years. These findings persisted in a sensitivity analysis of infertile patients stratified into AMH (ng/mL) quartile categories. CONCLUSION(S): No association was found between AMH and the proportion of euploid, mosaic, or aneuploid embryos in 2 large cohorts of patients undergoing IVF with PGT-A (Infertile patients) or PGT-A and PGT-M (Non-infertile patients), suggesting that a quantitative depletion of ovarian reserve does not predict the ploidy status of the embryo cohort.

OBJECTIVE: To determine the ongoing pregnancy rate among patients with infertility with a low antimüllerian (AMH) level compared with those with a normal AMH level after oral and injectable ovulation induction (OI)/intrauterine insemination (IUI). DESIGN: Retrospective cohort. SETTING: Academic center. PATIENT(S): Patients completing ≥1 medicated OI/IUI cycle at our center between 2015 and 2019 were included. The AMH levels were measured within 12 months of treatment initiation. The cohort was stratified into low AMH (AMH level, <1.0 ng/mL) and normal AMH (AMH level, ≥1.0 ng/mL) groups. All subsequent medicated OI/IUI cycles occurring within 1 year of initial cycle start date were included up to the third completed cycle or until an ongoing pregnancy was recorded. Patients were stratified by age (<35, 35-40, and >40 years), and the relationship between the low and normal AMH groups and each binary endpoint were quantified as risk ratios using the age-adjusted Poisson models. INTERVENTION(S): None. MAIN OUTCOME MEASURE(S): Ongoing pregnancy. RESULT(S): A total of 3,122 patients completed 5,539 oral antiestrogen cycles, and 1,060 completed 1,630 injectable gonadotropin cycles. For oral antiestrogen treatment, pregnancy outcomes, including ongoing pregnancy rate per cycle, for patients with a low AMH level were comparable with those for patients with a normal AMH level (<35 years, 15.4% vs. 14.9%; 35-40 years, 10.0% vs. 11.0%; and >40 years, 2.8% vs. 3.3%). For injectable gonadotropin treatment, the ongoing pregnancy rate was lower in the low AMH group than in the normal AMH group for the ages of <35 (12.1% vs. 23.5%; relative risk [RR], 0.52 [95% confidence interval {CI}, 0.28-0.97]) and 35-40 (12.5% vs. 18.5%; RR, 0.70 [95% CI, 0.49-0.99]) years but comparable with that for patients aged >40 years (3.0% vs. 4.0%; RR, 0.86 [95% CI, 0.31-2.35]). The proportion of multifetal gestations was similar between the low and normal AMH groups treated with oral antiestrogens (13.1% vs. 10.8%); however, for injectable gonadotropin treatment, patients with a normal AMH level had a higher proportion of multifetal gestations (18.6% vs. 31.1%). CONCLUSION(S): Compared with normal ovarian reserve, treatment with oral antiestrogens for OI/IUI for patients with low ovarian reserve results in comparable follicular development and ongoing pregnancy rates for all age groups. When patients with low ovarian reserve are treated with gonadotropins for OI/IUI, multifollicular recruitment is less likely resulting in a significantly decreased ongoing pregnancy rate for patients aged <35 and 35-40 years but also a decrease in multifetal gestations. Overall, the ongoing pregnancy rates of 8.7% per oral antiestrogen cycle and 8.1% per injectable gonadotropin cycle in patients with low ovarian reserve are comparable with the expected rates in the general infertility population.

RESEARCH QUESTION: Is household income or IVF insurance coverage associated with live birth outcomes in infertile women undertaking IVF? DESIGN: Retrospective cohort study in an academic hospital, including patients residing in New York State undergoing a frozen single embryo transfer at the study IVF centre between 1 January 2017 and 31 December 2018. Only the first embryo transfer per patient was included. Patients were stratified by tertiles of estimated income using home zip code census data: <$85,888 (nâ¯=â¯348), $85,888-122,628 (nâ¯=â¯348) and >$122,628 (nâ¯=â¯350). A second analysis stratified patients by IVF insurance coverage or no coverage. The primary outcome was live birth. Modified Poisson regression with robust error variance adjusted a priori for age, preimplantation genetic testing and previous fresh embryo transfer estimated the relative risk of outcomes with a 95% confidence interval. RESULTS: A total of 1046 patients were included. Live birth rate was similar among all three income tertiles. Secondarily, the pregnancy rate and pregnancy loss rate were also similar among all three tertiles. In the IVF insurance coverage analysis, live birth rate was similar between patients with and without IVF insurance coverage. Secondarily, the pregnancy rate and pregnancy loss rate were also similar among these two groups. CONCLUSION: Overall, neither median household income nor IVF insurance coverage of patients undergoing single frozen embryo transfer was associated with pregnancy, pregnancy loss or live birth outcomes. Lower income, relative to the patient cohort, and lack of insurance coverage are well-described barriers to accessing infertility evaluation and treatment. However, once treatment is initiated, the current results suggest that these variables do not influence pregnancy and live birth outcomes in infertile patients.

OBJECTIVE: To assess the association between body mass index (BMI) and embryo aneuploidy and mosaicism in a cohort of patients undergoing in vitro fertilization (IVF) with trophectoderm biopsy for preimplantation genetic testing for aneuploidy (PGT-A) using next-generation sequencing technology. DESIGN: Retrospective cohort study. SETTING: Academic center. PATIENTS: Patients undergoing their first IVF cycle with trophectoderm biopsy and PGT-A at our center between January 1, 2017, and August 31, 2020. Patients classified as underweight on the basis of BMI (BMI <18.5 kg/m2) and patients who underwent fresh embryo transfers were excluded. INTERVENTION: None. MAIN OUTCOME MEASURES: Number and proportion of aneuploid, mosaic, and euploid embryos. RESULTS: The patients were stratified according to the World Health Organization's BMI classification: normal weight (18.5-24.9 kg/m2, n = 1,254), overweight (25-29.9 kg/m2, n = 351), and obese (≥30 kg/m2, n = 145). Age-adjusted regression models showed no relationship between BMI classification and the number or proportion of aneuploid embryos. There were no statistically significant associations between BMI classifications and the number or proportion of mosaic or euploid embryos. A subgroup analysis of patients classified into age groups of <35, 35-40, and >40 years similarly showed no relationships between BMI and embryo ploidy outcomes. CONCLUSION: Body mass index was not associated with the number or proportion of aneuploid, mosaic, or euploid embryos in this large cohort of patients undergoing IVF with PGT-A, suggesting that the negative effect of excess weight on reproductive outcomes was independent of the ploidy status of the embryo cohort.

OBJECTIVE: To determine if the time from oocyte retrieval to frozen embryo transfer (FET) in the natural cycle affects reproductive or neonatal outcomes. DESIGN: Retrospective cohort. SETTING: Not applicable. PATIENT(S): Five hundred and seventy-six consecutive freeze-all cycles from January 2011 to December 2018 followed by natural cycle FET of a single blastocyst. INTERVENTION(S): None. MAIN OUTCOME MEASURE(S): Primary outcome of live birth; secondary outcomes of preterm delivery (24-37 weeks) and small for gestational age (SGA) with a multivariable logistic regression performed with adjustment for age, infertility diagnosis, ovulatory trigger type, and preimplantation genetic testing (PGT). RESULT(S): Before adjustment for confounding, we found a statistically significantly different live-birth rate (57.7% vs. 48.6%) for natural cycle FET occurring in the first versus second menstrual cycle, respectively. In a multivariate analysis, performing a natural cycle FET of a single blastocyst in the second compared with the first menstrual cycle did not statistically significantly impact the odds of live-birth rate. After adjustment for age, diagnosis, and ovulatory trigger type, only PGT was associated with statistically significantly increased odds of live birth compared with no PGT. There were no differences in the incidence of SGA (male, 6.6% vs. 2.3%; female, 9.8% vs. 11.1%) or preterm delivery (1.6% vs. 5.6%) between both groups. CONCLUSION(S): Performing a natural cycle FET of a single blastocyst in the second compared with the first menstrual cycle after ovarian stimulation did not statistically significantly impact the odds of live birth or neonatal outcomes.

PURPOSE: This study sought to identify the initiation of placental hormonal production as defined by the production of endogenous estradiol (E2) and progesterone (P4) in a cohort of patients undergoing programmed endometrial preparation cycles with single embryo transfers resulting in live-born singletons. METHODS: In this retrospective cohort study, patients undergoing either programmed frozen-thawed embryo transfer (FET) with autologous oocytes or donor egg recipient (DER) cycles with fresh embryos were screened for inclusion. Only patients who underwent a single embryo transfer, had a single gestational sac, and a resultant live-born singleton were included. All patients were treated with E2 patches and intramuscular progesterone injections. Main outcome measures were serial E2 and P4, with median values calculated for cycle days 28 (baseline), or 4w0d gestational age (GA), through 60, or 8w4d GA. The baseline cycle day (CD) 28 median value was compared to each daily median cycle day value using the Wilcoxon signed rank test. RESULTS: A total of 696 patients, 569 using autologous oocytes in programmed FET cycles and 127 using fresh donor oocytes, from 4/2013 to 4/2019 met inclusion criteria. Serum E2 and P4 levels stayed consistent initially and then began to increase daily. Compared to baseline CD 28 E2 (415 pg/mL), the serum E2 was significantly elevated at 542 pg/mL (P < 0.001) beginning on CD 36 (5w1d GA). With respect to baseline CD 28 P4 (28.1 ng/mL), beginning on CD 48 (6w6d GA), the serum P4 was significantly elevated at 31.6 ng/mL (P < 0.001). CONCLUSION: These results demonstrate that endogenous placental estradiol and progesterone production may occur by CD 36 and CD 48, respectively, earlier than traditionally thought.

RESEARCH QUESTION: What is the impact of low body mass index (BMI) on live birth rates and obstetric outcomes in infertile women treated with IVF and fresh embryo transfer? DESIGN: This was a retrospective cohort study of infertile patients in an academic hospital setting who underwent their first oocyte retrieval with planned autologous fresh embryo transfer between 1 January 2012 and 31 December 2018. The primary study outcome was live birth rate. Secondary outcomes were IVF treatment and delivery outcomes. Underweight patients were stratified into a significantly underweight group (body mass index [BMI] <17.5 kg/m2) and a mildly underweight group (BMI 17.5-18.49 kg/m2), and were compared with a normal-weight group (BMI 18.5-24.9 kg/m2). RESULTS: A total of 5229 patients were included (significantly underweight, 76; mildly underweight, 231; normal weight, 4922), resulting in 4798 embryo transfers. After oocyte retrieval, there were no significant differences between groups for total oocytes, mature oocyte yield and number of supernumerary blastocysts cryopreserved. Among women who had an embryo transfer, there were no significant differences in the live birth rates in significantly (31.0%, odds ratio [OR] 0.67, confidence interval [0.95, CI] 0.40-1.13) and mildly (37.7%, OR 0.95, CI 0.73-1.33) underweight patients compared with normal-weight patients (35.9%). Additionally, there were no statistically significant increased risks of preterm delivery, Caesarean delivery or a low birthweight (<2500 g) neonate. CONCLUSIONS: Mildly and significantly underweight infertile women have similar pregnancy and live birth rates to normal-weight patients after IVF treatment. In addition, underweight patients do not have an increased risk of preterm delivery (<37 weeks), Caesarean delivery or a low birthweight neonate.

OBJECTIVE: Assess the effect of class III (body mass index [BMI, kg/m2] 40-49.9) and class IV obesity (≥ 50) on clinical pregnancy and live birth outcomes after first oocyte retrieval and fresh embryo transfer cycle. DESIGN: Cohort study SETTING: Academic center PATIENTS: Patients undergoing their first oocyte retrieval with planned fresh embryo transfer in our clinic between 01/01/2012 and 12/31/2018. Patients were stratified by BMI: 18.5-24.9 (n = 4913), 25-29.9 (n = 1566) 30-34.9 (n = 559), 35-39.9 (n = 218), and ≥ 40 (n = 114). INTERVENTION: None MAIN OUTCOME MEASURE: Live birth rate RESULTS: Following embryo transfer, there were no differences in pregnancy rates across all BMI groups (p value, linear trend = 0.86). However among pregnant patients, as BMI increased, a significant trend of a decreased live birth rate was observed (p value, test for linear trend = 0.004). Additionally, as BMI increased, a significant trend of an increased miscarriage rate was observed (p value, linear trend = < 0.001). Compared to the normal-weight cohort, women with a BMI ≥ 40 had a significantly higher rate of cancelled fresh transfers after retrieval (18.4% vs. 8.2%, OR 2.51; 95%CI 1.55-4.08). Among singleton deliveries, a significant trend of an increased c-section rate was identified as the BMI increased (p value, linear trend = <0.001). CONCLUSION: Overall, patients with a BMI > 40 have worse IVF treatment outcomes compared to normal-weight patients. After embryo transfer, their pregnancy rate is comparable to normal-weight women; however, their miscarriage rate is higher, leading to a lower live birth rate for pregnant women in this population. Patients with a BMI > 40 have a c-section rate that is 50% higher than normal-weight patients.

The relationship between diet quality and ovarian morphology has biological plausibility yet remains unclear and was therefore evaluated. In a multicenter cross-sectional analysis, four dietary patterns were scored for 111 consecutive reproductive-aged women (18-45 years) using (1) Healthy Eating Index (HEI-2015); (2) alternative HEI-2010; (3) alternate Mediterranean Diet (aMED); (4) and Dietary Approaches to Stop Hypertension (DASH) indices. Ovarian volume (OV) and follicle number per ovary (FNPO) were evaluated on transvaginal ultrasonography. Relationships between dietary and ovarian morphology indices were evaluated by linear regression and mediation analyses. Associations between aMED and DASH scores and OV/FNPO were completely mediated by obesity, insulin resistance, and hyperandrogenism (All: p < 0.05), unlike direct associations (All: p ≥ 0.89). Namely, a 1-standard deviation [SD] increase in aMED score was associated with decreases in OV (0.09 SD; 0.4 mL) through reducing waist circumference. Likewise, a 1 SD increase in aMED and DASH score was associated with decreases in OV (0.07 SD; 0.3 mL) by reducing glucose response to a 75 g glucose tolerance test. A 1 SD increase in DASH score was associated with decreased FNPO (0.07 SD; 2 follicles) by reducing free androgen index (All: p < 0.05). Adherence to aMED and DASH eating plans was indirectly associated with significant improvements in ovarian form, providing novel mechanistic insights for future interventions about contributions of diet quality on ovarian function.

CONTEXT: Osteosarcopenia (loss of skeletal muscle and bone mass and/or function usually associated with aging) shares pathophysiological mechanisms with polycystic ovary syndrome (PCOS). However, the relationship between osteosarcopenia and PCOS remains unclear. OBJECTIVE: We evaluated skeletal muscle index% (SMI% = [appendicular muscle mass/weight (kg)] × 100) and bone mineral density (BMD) in PCOS (hyperandrogenism + oligoamenorrhea), and contrasted these musculoskeletal markers against 3 reproductive phenotypes (i): HA (hyperandrogenism + eumenorrhea) (ii); OA (normoandrogenic + oligoamenorrhea) and (iii), controls (normoandrogenic + eumenorrhea). Endocrine predictors of SMI% and BMD were evaluated across the groups. DESIGN, SETTING, AND PARTICIPANTS: Multicenter case-control study of 203 women (18-48 years old) in New York State. RESULTS: PCOS group exhibited reduced SMI% (mean [95% confidence interval (CI)]; 26.2% [25.1,27.3] vs 28.8% [27.7,29.8]), lower-extremity SMI% (57.6% [56.7,60.0] vs 62.5% [60.3,64.6]), and BMD (1.11 [1.08,1.14] vs 1.17 [1.14,1.20] g/cm2) compared to controls. PCOS group also had decreased upper (0.72 [0.70,0.74] vs 0.77 [0.75,0.79] g/cm2) and lower (1.13 [1.10,1.16] vs 1.19 [1.16,1.22] g/cm2) limb BMD compared to HA. Matsuda index was lower in PCOS vs controls and positively associated with SMI% in all groups (all Ps ≤ 0.05). Only controls showed associations between insulin-like growth factor (IGF) 1 and upper (r = 0.84) and lower (r = 0.72) limb BMD (all Ps < 0.01). Unlike in PCOS, IGF-binding protein 2 was associated with SMI% in controls (r = 0.45) and HA (r = 0.67), and with upper limb BMD (r = 0.98) in HA (all Ps < 0.05). CONCLUSIONS: Women with PCOS exhibit early signs of osteosarcopenia when compared to controls likely attributed to disrupted insulin function. Understanding the degree of musculoskeletal deterioration in PCOS is critical for implementing targeted interventions that prevent and delay osteosarcopenia in this clinical population.
