Figure 4: Effects of different FSH preparations on sperm concentration and total sperm count. Both hpFSH and rhFSH improved (a) the sperm concentration and (b) the total sperm count. FSH: follicle-stimulating hormone; hpFSH: highly purified FSH; rhFSH: recombinant human FSH; CI: confidence interval; s.d.: standard deviation; a–d: study subgroups; IV: Inverse Variance methods; df: degree of freedom.
