Figure 5: Effects of different FSH preparations on progressive sperm motility and morphology. (a) Both hpFSH and rhFSH increased the progressive sperm motility. (b) Neither of them improved the sperm morphology. FSH: follicle-stimulating hormone; hpFSH: highly purified FSH; rhFSH: recombinant human FSH; CI: confidence interval; s.d.: standard deviation; std: standard; a–d: study subgroups; IV: Inverse Variance methods; df: degree of freedom.
