Plasma LH concentration following treatment with 10ρg (A), 1ηg (B) and 1µg (C) doses after 2, 4, 6, 8, 10 and 12 days of alone kisspeptin treatment. LH levels increased significantly after 4 days of treatment at 1ηg and 1µg doses but decreased afterwards. The decrease was significant after 12 days of treatment. The levels remained unaltered at 10ρg dose as compared to control throughout the experiment. Values are expressed as mean ± SE (n=7). *p<0.05, **p<0.01.
