Design outcomes

Primary

MeasureTime frame
Improvement of menstrual cyclicity evidence by Proportion of resumption of normal menstrual cycle and menstrual frequency (number of menses/ month) The typical menstrual cycle pattern is 28 ± 7 days with menstrual flow lasting 4 ± 2 days and blood loss averaging 20 to 60 mL. Menstrual Cycle Patterns: will be assessed by cycle frequency, duration, regularity and volume. Frequency is defined as the interval between menstrual cycles, duration as the period from the beginning to the end of menstrual bleeding and regularity as variations of menstrual cycle length. [Day 1, 14, 21 , 2 months from visit 1 and final visit at 3 months from visit 1 ] Change in serum androgen level (total testosterone, SHBG and LH/FSH ratio) [ Day 1 and and final visit at 3 months from visit 1 ] Change in serum androgen level (total testosterone, SHBG and LH/FSH ratio) [ Day 1 and and final visit at 3 months from visit 1 ]

Secondary

MeasureTime frame
Change in ovarian morphology and endometrial thickness evidence by the ultrasound scanning [Day 1, 14, 21 , 2 months from visit 1 and final visit at 3 months from visit 1 ] Change in insulin sensitivity indices, would be measured by homeostasis model assessment insulin-resistant (HOMA-IR) calculations based on fasting blood glucose and fasting serum insulin [ Day 1 and and final visit at 3 months from visit 1 ] Improvement of glycemic and metabolic indices evidenced by fasting blood sugar, OGTT, HbAIC and triglyceride and cholesterol (LDL, HDL, and total) [ Day 1 and and final visit at 3 months from visit 1 ] Change in circulatory hormones including FSH, LH, E2, P4, AMH, chemerin [ Day 1 and and final visit at 3 months from visit 1 ] Change in weight evidence by BMI and change in body fat distribution evidenced by, waist circumference (WC), hip circumference (HC), and waist/hip ratio. [ Day 1 and and final visit at 3 months from visit 1 ] Change in insulin sensitivity indices, would be measured by homeostasis model assessment insulin-resistant (HOMA-IR) calculations based on fasting blood glucose and fasting serum insulin [ Day 1 and and final visit at 3 months from visit 1 ] Improvement of glycemic and metabolic indices evidenced by fasting blood sugar, OGTT, HbAIC and triglyceride and cholesterol (LDL, HDL, and total) [ Day 1 and and final visit at 3 months from visit 1 ] Change in circulatory hormones including FSH, LH, E2, P4, AMH, chemerin [ Day 1 and and final visit at 3 months from visit 1 ] Change in weight evidence by BMI and change in body fat distribution evidenced by, waist circumference (WC), hip circumference (HC), and waist/hip ratio. [ Day 1 and and final visit at 3 months from visit 1 ] [Include safety outcome here] [ Respective time/period of assessment]
