| Abstract: | Urinary excretion of 10 C21 steroids was investigated in women and baboons (Papio hamadryas) in various stages of pregnancy, in comparison to controls. In pregnant women, excretion of total C21 steroids is slightly increased, whereas in pregnant baboons it is slightly decreased. In women, excretion of tetrahydrocortisol and tetrahydrocortisone is diminished, that of 20 beta-OH-F (11-beta,17alpha,20beta,21-tetrahydroxy-4-pregnen-3,20-dione) and of 11-deoxycortisol is increased. In pregnant baboons no significant alterations in corticosteroid metabolism were established. |
