A single dose of oral androstenedione increases testosterone levels, and to a lesser extent estrone levels, in postmenopausal women, according to a new study.
“If these hormonal effects are sustained during long-term administration, regular use of this supplement by postmenopausal women could thus cause both beneficial and adverse effects,” the researchers conclude.
Women, as well as men, are known to use over-the-counter androstenedione for its perceived effects on strength, libido, well-being and quality of life, Dr. Benjamin Z. Leder and his research team note in the Journal of Clinical Endocrinology and Metabolism for December.
