title: Human chorionic gonadotropin production by the pituitary gland in a premenopausal woman.
abstract: OBJECTIVE
  Our purpose was to investigate the source of human chorionic gonadotropin production in a nonpregnant, premenopausal woman.
  
  
  METHODS
  A case of human chorionic gonadotropin production by the pituitary gland in a premenopausal woman is described.
  
  
  RESULTS
  Our results confirm that a biologically active human chorionic gonadotropin-like molecule was secreted in a nonpregnant woman.
  
  
  CONCLUSIONS
  Our results indicate that the pituitary gland was the most likely source of human chorionic gonadotropin production.
