Hormonal and vitamin d metabolic profiles in reproductive-age women with abnormal uterine bleeding and associated extragenital conditions

Conclusions: The study revealed distinct features of the hormonal profile and vitamin D metabolism in women of reproductive age with abnormal uterine bleeding and concomitant extragenital conditions. Specifically, this patient population demonstrated decreased serum levels of LH, FSH, PRG, and vitamin D, accompanied by hyperestrogenemia. A statistically significant correlation was observed between serum E2 and vitamin D levels.
