Brief Summary: LM001 is a recombinant human Follicle Stimulating Hormone (r-hFSH) Injection, which is proposed for Assisted Reproductive Technology (ART). This is a randomized, open-label, two-period, two-crossover study to evaluate the safety and pharmacokinetics of recombinant human follicle stimulating hormone injection (LM001), compared with Gonal-F®, both given subcutaneously.
