This was a prospective, randomised, Phase II, comparative study with a parallel control for evaluating the efficacy and safety of combined treatment of recombinant human follicle stimulating hormone (r-hFSH) and recombinant human luteinizing hormone (r-hLH). The combined treatment was administered at the middle of the follicular phase in subjects undergoing in-vitro fertilisation (IVF) through intracytoplasmic sperm injection (ICSI) and transfer of embryos (ET).
