Taymor, Boston, Massachusetts states on page 416, “The special contribution of this paper is the correlation of the changes in the end-organ responses, i.e. BBT, and changes in cervical mucus, with the hormonal changes. As a result, these changes which are naturally of more interest to the clinician, are placed on a firmer physiologic basis.”
