title: Steroid levels after intramuscular injection of testosterone propionate in the caprine.
abstract: Nine sexually mature intact grade does were injected intramuscularly with testosterone propionate and subsequent plasma steroid concentrations determined and male-like behavior recorded. The does received either 100 mg testosterone propionate every three days for six treatments, total dose 600 mg (N = 5); 50 mg testosterone propionate daily for eighteen days, total dose 900 mg (N = 2) or 10 mg testosterone propionate daily for eighteen days, total dose 180 mg (N = 2). The treatments induced male-like sex behavior, the intensity of which was related to the dose of exogenous testosterone used, the regimen of administration, and the plasma levels of testosterone. Exogenous testosterone treatment had minimal effect on the subsequent reproductive activity of the does.
