title: Application of Chinese hamster ovary cells transfected with the recombinant human follicle-stimulating hormone (FSH) receptor for measurement of serum FSH.
abstract: OBJECTIVE
  To evaluate the activity of the serum FSH bioactivity in patients with premature ovarian failure (POF).
  
  
  METHODS
  Prospective study.
  
  
  METHODS
  Infertility and gynecology outpatient clinics at the Gunma University School of Medicine, Gunma, Japan.
  
  
  METHODS
  Twelve women, aged 27 to 39 years, with POF and nine postmenopausal women.
  
  
  METHODS
  Serum samples obtained from postmenopausal women and POF patients. The immunoglobulin (Ig)G fractions of some sera from POF patients were prepared by 20% polyethylene glycol.
  
  
  METHODS
  Serum samples were measured simultaneously by the bioassay system and immunoradiometric assay (IRMA).
  
  
  RESULTS
  The bioassay values correlated with those obtained by IRMA, and the correlation coefficient and the slope of the regression lines calculated from nine pairs of assay values from the postmenopausal women were 0.867 and 1.10, respectively. The mean of the biologic:immunologic ratios of sera from postmenopausal women and POF patients were 1.44 and 1.25, respectively.
  
  
  CONCLUSIONS
  The IgG fractions of some sera from POF patients showed stimulatory or inhibitory effect on cyclic adenosine 3':5' monophosphate production compared with that from postmenopausal women. These results may reflect the more complex pathophysiological states of the patients with POF.
