Prostate responses to a small dose of PRL insexually active males. The treatment with daily doses of ovine PRL (▼) in sexually active males did not modify the weight of the prostate. However, a decrement was observed in the alveoli area of the ventral prostate, and also it was observed a reliable increase of this parameter in the dorsal prostate after 15 days of treatment or fifth behavioural test. The epithelium height was increased starting at the day 9 or third behavioural tests in both regions of the prostate. The incremental slope was constant with a higher magnitude at the ventral prostate. No modification was observed in untreated (◯) or vehicle treated (●) males. * = p < 0.05; ** = p < 0.01.
