title: Frequency of rate of body temperature chart at mid cycle in pregnant women and the subsequent effect on pregnancy.
abstract: OBJECTIVE
  To determine if changes in basal body temperature (BBT) during the ovuratory phase are related to subsequent effects on pregnancy.
  
  
  METHODS
  BBT records from 216 pregnant women in a spontaneous cycle or a clomiphene citrate cycle during a recent 6-year period were studied. The last day of low phase (LDLP) and the number of days until high phase (NDHP) were determined for all subjects.
  
  
  RESULTS
  In the spontaneous cycle group, medium-cycle cases were most frequent and long-cycle cases were most frequent in the clomiphene cycle group. The NDHP ranged between one and three days in 82.8% of the subjects in the spontaneous cycle group and in 86.1% of the subjects in the clomiphene cycle group.
  
  
  CONCLUSIONS
  Our findings demonstrate the importance of properly evaluating an NDPH of two or even three days in a BBT-based assessment of ovarian function in the ovulatory phase.
