Detaljeret beskrivelse
Vitamin D was measured on the sixth day of stimulation. According to vitamin D level, women were divided into 2 groups (deficiency when 25(OH)D <20 ng/ml and sufficient when 25(OH)D >20 ng/ml).
Pregnancy rates were compared among these two groups after controlling age, BMI, characteristics of ovarian stimulation, number of ovocytes obtains, etc.
