Serum inhibin A and B levels. (A) inhibin A and (B) inhibin B levels before (white bars) and 24 hours after a single injection of recombinant FSH (450 IU sc) (black bars) in 10 women with PCOS and 8 normally cycling women (control). The FSH injection was given to the women with PCOS twice, i.e. first 15-20 days after a spontaneous period (before progesterone treatment) and second after a 20-days treatment with progesterone per os (after progesterone treatment). The FSH injection was given to the normally cycling women on cycle day 3. After the FSH injection, serum inhibin A and inhibin B levels increased significantly in the women with PCOS but not in the control women. A. a,b,c,e,f p < 0.05, d p < 0.001 B. a,b p < 0.05.
