Blood Levels of Fsh, Lh, Tsh, and Gh in Parkinsonian Patients Before and During L-Dopa Treatment

Serum levels of FSH, LH, TSH, and GH were studied in 17 parkinsonian patients before treatment with L-DOPA and in 25 patients during treatment with L-DOPA. A radioimmunosorbent technique was used. With few exceptions the hormone levels were normal in the non-treated patients. No statistically significant differences between the treated and non-treated patients were found.
