For the PCOS group there was non significant correlation between basal serum LH and CP (R2 = 0.02, F = 1.7 and P= 0.76) or to LB (R2 = 0.01, F = 2.6 and P = 0.77) after adjusting for age, BMI, day of oocyte retrieval, starting dose, total dose of stimulation, type of gonadotrophin used, number of oocytes retrieved, fertilization rate and number of embryos transferred. This evidence concerns the gene CP and polycystic ovary syndrome.
