[QUOTE="Nelson Vergel, post: 39174, member: 3"] Characterized by low serum testosterone levels and diverse symptoms, male hypogonadism is a common condition. Current medical treatment focuses on testosterone supplementation using multiple modalities such as injections, gels and pellets. Interestingly, while testosterone is considered an anabolic androgenic steroid, it has not been saddled with the social stigma that other, similar medications have. The goal of this review is to highlight an anabolic steroid, 19-nortestosterone (i.e., nandrolone, deca-durabolin) and illustrate prospective therapeutic applications for male health. Containing a chemical structure similar to testosterone, nandrolone has a higher myotrophic: androgenic ratio resulting in improved effects on muscle mass. Animal models have suggested application in the improvement of joint healing following rotator cuff repair. Minimal literature exists regarding the use of nandrolone and, as such, further human studies are required. [B]Nandrolone and joint healing[/B] Recent studies in animal models have identified a potential role for nandrolone in joint pain, particularly post rotator cuff tears ([URL='http://www.ncbi.nlm.nih.gov/pmc/articles/PMC4837307/#r31']31[/URL],[URL='http://www.ncbi.nlm.nih.gov/pmc/articles/PMC4837307/#r32']32[/URL]). In one such study by Gerber[I]et al[/I].
