Forty eight POP women were divided into experimental and control groups in this quasi-experimental study. The experimental group was given 0.5 mcg alfacalcidol orally for three months. We measured levator ani muscle strength, serum 25-hydroxy-vitamin D3 levels, and serum Vitamin D Receptor (VDR) levels at zero months and three months preoperative. Enzyme-linked immunosorbent assay (ELISA) assessed VDR and myoblast determination protein 1 (MyoD) protein expressions in levator ani muscle surgical biopsies.
This is a study performed to evaluate the role of vitamin D supplementation on the strength of levator ani muscle in menopausal women with pelvic organ prolapse
