    AbstractThe association between early pregnancy ultrasound parameters and reproductive hormone levels was investigated through a case-control study. Participants for this retrospective study were recruited from obstetrics and gynecology departments across multiple tertiary care centers over 2 years. Inclusion criteria for the case group included pregnant women in their first trimester with detailed ultrasound data, while the control group comprised nonpregnant women without hormonal disorders. A sample size of 850 was estimated to provide sufficient power for detecting differences in hormone levels. Hormone levels were assayed using enzyme-linked immunosorbent assay, and statistical analysis was performed using Statistical Package for the Social Sciences 26.0. A total of 425 participants in each group were included after accounting for dropouts. For hCG, a strong positive correlation was observed with crown-rump length (R = 0.62, P < .001), gestational sac diameter (R = 0.59, P < .001), and a moderate correlation with yolk sac diameter (R = 0.40, P = .003). Progesterone levels exhibited moderate positive correlations with these ultrasound parameters, and estradiol levels demonstrated strong positive correlations. Conversely, follicle-stimulating hormone levels showed a moderate negative correlation with ultrasound measurements, while luteinizing hormone levels indicated a slight negative correlation. Prolactin levels were positively correlated with all ultrasound parameters in cases. The control group did not show any significant correlations between hormone levels and ultrasound parameters. The study concluded a significant association between early pregnancy ultrasound parameters and reproductive hormone levels in pregnant women, underscoring the potential of these hormones as biomarkers for pregnancy development.Copyright © 2024 the Author(s).
