At the time of cabergoline discontinuation, both groups had similar prolactin levels [median 6.0 (2.5–10.0) ng/ml vs 4.0 (1.0–7.0) ng/ml], testosterone levels (5.8 ± 1.7 ng/ml vs 5.2 ± 2.4 ng/ml), and mean pituitary adenoma size (3.0 ± 1.4 mm vs 3.8 ± 1.3 mm; Table 4). Here, PRL is linked to pituitary gland adenoma.
