To investigate whether endurance running in men produced basal hormonal changes similar to those reported in women, we obtained blood samples from 31 men running at least 64 km each week and 18 sedentary controls for measurement of levels of total testosterone, non-sex hormone-binding globulin-bound and free testosterone, luteinizing hormone, follicle-stimulating hormone, prolactin, and cortisol. The mean levels of total and nonspecifically bound testosterone as well as prolactin were significantly lower than in controls, although levels remained within the physiological range. Other hormone levels were similar in both groups. The lowered testosterone and prolactin levels parallel the changes reported in women runners.

Hormones and Behaviour in Higher Vertebrates pp Cite as. The brain is known to control a variety of functions which differ in males and females. Many of these functions become irreversibly organized under the influence of hormones during particular developmental stages. Two of the best-studied sexually differentiated brain functions in a variety of animals are the patterns of gonadotropic hormone release and sexual behaviour.

Objective: To evaluate the safety and effectiveness of lanreotide Autogel on growth hormone and insulinlike growth factor 1 IGF-1 concentrations and tumor size in patients with acromegaly. Methods: Between September and March , patients with active acromegaly who had not previously been treated with somatostatin analogues or received irradiation were enrolled in a 1-year, prospective, open, multicenter study. Tumor shrinkage, clinical score, pituitary function, and safety parameters were evaluated. Results: Twenty-seven patients 15 women, 12 men were enrolled.
