TASK ORDER 19: INVITED

这项工作实施了一项II期，剂量范围，随机临床试验（“维生素D和月经周期试验的研究：II期随机试验”），研究维生素D对下丘脑-垂体-卵巢轴的影响。该研究将仔细评估维生素D治疗引起的激素、排卵和整个月经周期的变化。补充维生素D可能是一种低成本的干预措施，可以改善月经周期功能和生育能力。

This work implements a Phase II, dose-ranging, randomized clinical trial (“The Investigation of Vitamin D and Menstrual Cycles Trial: A Phase II Randomized Trial”) investigating vitamin D’s influence on the hypothalamic-pituitary-ovarian axis. The study will carefully evaluate the hormonal, ovulatory, and overall menstrual cycle changes that occur with vitamin D treatment. Vitamin D supplementation may be a low-cost intervention that improves menstrual cycle function and fertility.
