Progesterone in saliva as an index of ovarian function.

Author information

Department of Obstetrics and Gynecology, University College Hospital, Ibadan, Nigeria.


Progesterone was assayed in samples of saliva collected daily throughout the menstrual cycle and correlated with corresponding daily concentrations of pregnanediol-3 alpha-glucuronide in early morning urine. Ovarian follicular growth was monitored on a daily basis with a real-time sector scanner. The concentrations of salivary progesterone shows a specific pattern with a mid-cycle rise and a peak in the luteal phase. The mean concentration in the follicular phase, as determined, was 40.4 pmol/l (range 15.3-110.7 pmol/l). It increased in the peri-ovulatory period to a peak of 201.1 pmol/l (range 46.4-289.8 pmol/l) 6 days following follicular rupture.
