An oxygen electrode was maintained by suction on the vaginal wall in seven women. The basal value of pO2 was 9.3 mm Hg +/- 10.7 (mean +/- standard deviation) before clitoral self-stimulation was initiated. When stimulation took place the oxygen tension rose and peaked immediately after orgasm to 39.5 +/- 14.1 mm Hg. It then declined and fell to 20.1 +/- 13.8 mm Hg 10 minutes after the peak value. The changes correlate closely with changes in vaginal blood flow. The increased oxygen tension may… CONTINUE READING
