Portable device for vaginal thermal conductance studies.
Design and development of a portable and self-contained vaginal probe, consisting of an acetone-filled silver cylinder attached to a pressure gauge, is described. Qualitative changes in vaginal thermal conductance were inferred from rates of thermal expansion of precooled acetone measured as a pressure rise. Administration of 10 mg estradiol-17 beta i.v. to ovariectomized heifers resulted in significant increases in rate of thermal expansion.
