Number of elongated spermatid heads per gram of testis following 10ρg (A), 1ηg (B) and 1µg (C) doses after 2, 4, 6, 8, 10 and 12 days of alone kisspeptin treatment. A few elongated spermatids were observed before 41 days i.e. at 6 days of kisspeptin treatment. Elongated spermatids decreased significantly at all doses. Values are expressed as mean ± SE (n=7). *p < 0.05, **p< 0.01, ***p< 0.001.
