Abstract
OBJECTIVE: The frequencies of one subject's spontaneous otoacoustic emissions (SOAEs) were tracked intermittently for 295 days. DESIGN: The first 40 days encompassed a normal menstrual cycle. During the next 186 days, the subject exhibited amenorrhea. For the last 69 days, she took oral contraceptives prescribed by her doctor to reestablish menstrual function. RESULTS: Anovulation, as evidenced by amenorrhea or induced by oral contraception, reduced the fluctuation of SOAE frequencies relative to the naturally occurring menstrual cycle. CONCLUSIONS: Future research might fruitfully be aimed at monitoring SOAE frequencies in humans and animals to determine whether the fluctuations can provide a noninvasive measure of the functioning of the pituitary-gonadal axis.
