A cohort study of both human menopausal gonadotropin (HMG) and recombinant luteinizing hormone addition at early follicular stage in in vitro fertilization outcome: A STROBE-compliant study

At present, the precise role of human menopausal gonadotropin (HMG) and recombinant luteinizing hormone (rLH) supplementation at an early time of follicular phase on in vitro fertilization (IVF)/intra cytoplasmatic sperm injection (ICSI) outcomes remains uncertain. Here infertile women of normal ovarian function undergoing their first cycle of IVF/ICSI were studied and were randomly allocated into 3 groups. Group 1, ovarian stimulation with 150IU recombinant follicle-stimulating hormone (FSH) alone. Group 2, patients received 75IU rFSH and 75IU HMG. Group 3 patients were given 150IU rFSH and 75IU rLH. There were no significant differences in the clinical characteristics, ovarian response, the biochemical, clinical and ongoing pregnancy rates among the 3 groups. No significant differences were found in biochemical, clinical and ongoing pregnancy rates between the patients whose LH levels were lower than 0.75 mIU/ml and those above this threshold in group 1. Furthermore, there were also no significant differences in biochemical, clinical and ongoing pregnancy rates among the 3 group patients whose LH level lower than 0.75 mIU/ml. The results showed that either the addition of HMG or rLH supplementation at an early time of follicular phase produce no significant benefit on IVF outcome in patients with normal ovarian function.
