Figure 2From: Prostate response to prolactin in sexually active male ratsSerum levels of PRL after Treatments. The graph represents the estimated daily profile of PRL in serum after experimental treatments. Lines show the comparison between basal values (◯) and the values obtained after treatments with haloperidol (▼), pituitary grafts transplants (▽), and ovine PRL administration (●). Thus, the experimental paradigms allowed continuous levels and transient levels. Each point represents the mean value. The profile induced by sexual behaviour is not represented (see Fig. 1).Back to article page
