randomized controlled study of comparing follitrope versus gonal-f in chinese infertility women.

Conditions: Infertility, Female

Summary: this study is for evaluating safety and efficacy of recombinant human follicle-stimulating hormone (follitrope) injection compared with gonal-f® pen undergoing controlled ovarian hyper stimulation in vitro fertilization - embryo transfer (ivf-et) in china

this is a phase 3, multicenter, blinded, randomized, controlled, parallel, comparative study for the evaluation of safety and efficacy of recombinant human follicle-stimulating hormone injection (follitrope) compared with gonal-f® pen undergoing controlled ovarian hyper stimulation in vitro fertilization - embryo transfer (ivf-et) in china.
