Figure 3. Serum levels of FSH and LH in controls and patients on hemodialysis and erythropoietin values are mean + SEM. * P< 0.05 , * *P< 0.01 and ***P< 0.001 as compared with age matched healthy subjects using Kruskalwallis H with Mann Whitney U test. No significant difference was observed between the levels of the hormones in the two different patient groups. FSH = Folicle stimulating hormone, LH = Leutinizing hormone, Contr = Normal subjects Pat = patients on hemodialysis and on erythropoietin, Gp1, Gp2 = groups with age < 45 and >45 respectively.
