Polycystic ovarian syndrome (PcOS) disrupts ovulation leading to both infertility and miscarriage;yet, its impact on obstetrical outcomes remains largely uncertain due to conflicting findings. We analyzed data from the cDc Pregnancy Risk Assessment of Monitoring System, specifically Standard core and Phase 8 responses, with 9549 respondents across the United States through SPSS 28 software in this cross-sectional study. Two variables assessed PcOS status in respondents: history of PcOS and PcOS during pregnancy. With a history of PcOS, there were significantly increased odds of diabetic (OR 1.665, p cy, neonatal mortality (OR 1.550, p cesarean section (c/S) (OR 1.489, p cOS diagnosed during pregnancy, there were significantly greater odds of diabetes (OR 3.278, p cy, and significantly decreased risk for small for gestational age (2 standard deviations) (OR 0.337, p = 0.024). PcOS is a significant risk factor that contributes to maternal morbidity. Our results support the hypothesis that PcOS’ impact extends well into a woman’s obstetrical journey, with varying degrees of associated adverse maternal and fetal risks. Preliminary pathophysiologic explanations associated with PcOS gestational diabetes include pre-existing insulin resistance. Meanwhile, altered placentation and endovascular changes associated with PcOS secondary to a baseline deranged metabolic environment predispose patients to developing hypertensive disorders, PPROM, and preterm delivery. Associations between neonatal mortality and c/S can be attributed to elevated maternal body mass index. The pathophysiologic link between PcOS and the above obstetrical outcomes still remains unknown, necessitating further investigation;however, this study identifies the outcomes that

Background: certain ovarian cancers that were previously common in postmenopausal women are now increasingly observed in women of reproductive age. The research on using β-HcG as a diagnostic biomarker for ovarian cancer in women of reproductive age is ongoing. Aim: This study assessed the level of serum β-HcG in non-pregnant women of reproductive age and determined its potential association with suspicious ovarian ultrasonography results. Methods: The study was conducted in Port Harcourt, Nigeria. This study adopted a cross-sectional design on a quota sample of 224 case notes of women aged 18 - 40 years obtained from eight diagnostic centres. A data extraction form was used for data collection. Data analysis employed descriptive statistics, chi-square, fisher’s exact test, and Odds Ratio at 95% confidence and 5% significance levels. Results: About 5.8% of the participants exhibited detectable levels of serum β-HcG above 5 IU/L (World Health Organization reference) at a mean concentration of 5.87 (±1.75) IU/L. About 4.0% of the participants had suspicious ovarian lesions identified through ultrasonography. Participants with elevated serum β-HcG levels above the WHO reference were 59 times more likely to have suspicious ovarian lesions (Odds ratio: 59.4, 95%cI: 12.3 - 287.8, p β-HcG level and age (p = 0.041) as well as parity (p conclusion: Serum β-HcG levels above the WHO reference in non-pregnant women were associated with suspicious ovarian lesions. More rigorous primary research, systematic reviews, and meta-analyses are needed to confirm the findings of this study.
