Muscle growth and Testes

http://www.ncbi.nlm.nih.gov/pubmed/15753334

Points of note from this study are...

- Testosterone is known to act differentially on skeletal muscle from different regions, Sexual dimorphism in muscle growth relates to the protein anabolic effect of testicular hormones.

- Testosterone through the androgen receptor can stimulate local IGF-1 which increases muscle mass independent of myostatin.
