title: Effect of age on plasma androstenedione concentration in oophorectomized women.
abstract: Plasma androstenedione concentration was measured in 92 oophorectomized women in the age range 33 to 76 years. Although this concentration was significantly inversely correlated with age, the data suggest a discrete change in the first half of the sixth decade rather than a continuous fall.
