title: Infusions of hFSH and hLH in normal men. I. Kinetics of human follicle stimulating hormone.
abstract: Serial serum assays of immunoreactive FSH before, during and after a 4 h intravenous infusion of human follicle stimulating hormone (hFSH) in five healthy men revealed two disappearance rate constants with corresponding mean half-lives of 2.9 and 50.6 h. The mean distribution spaces calculated for the fast and slow component were 4.36 1 and 75.9 1 respectively. The average value for the metabolic clearance rate was 17.2 ml/min and for the endogenous production rate 50.9 mU/min. Two of the subjects had human luteinizing hormone (hLH) added in the infusions without the FSH kinetics changing.
