[Effect of Ginkgo biloba extract on biological endocrine parameters].

In order to find out whether Ginkgo biloba extract has an influence on endocrine balance, 7 male volunteers (mean age: 26.1 years) received twice the usual dose of the drug for 8 weeks. Different hormonal assays and stimulation tests with LHRH and TRH were performed before, and 4 and 8 weeks after treatment. No significant change or tendency to change was observed. The other, usual blood tests also were unmodified.
