HMG improves IVF outcome in patients with high basal FSH/LH ratio: a preliminary study.
In an attempt to examine the role of human menopausal gonadotrophin (HMG) administration in patients with high basal FSH/LH ratio, patients undergoing at least two IVF cycles, where one included HMG (HMG group) and the other included recombinant FSH (rFSH) only (FSH group), were studied. The use of HMG, in this specific group of patients, produced significantly higher number of top-quality embryos (3.9 +/- 3.1 versus 2.5 +/- 1.7, respectively; P < 0.05), higher implantation (27.9% versus 5.3%, respectively; P +/- 0.003) and clinical pregnancy rates (44.4% versus 11.1%, respectively; P < 0.02), as compared with rFSH. Moreover, while the HMG group achieved a significantly higher peak oestradiol concentration (P = 0.04), no differences were observed between the groups in the other ovarian stimulation variables. In conclusion, the use of HMG in patients with high basal FSH/LH ratio, produced significantly higher number of top-quality embryos, and higher implantation and clinical pregnancy rates, compared with rFSH.
