Effect of nutrition on testicular growth and plasma concentrations of gonadotrophins, testosterone and insulin-like growth factor I (IGF-I) in pubertal male Soay sheep






Journal of Reproduction and Fertility 111(1): 121-125

Effect of nutrition on testicular growth and plasma concentrations of gonadotrophins, testosterone and insulin-like growth factor I (IGF-I) in pubertal male Soay sheep

Groups of 8 lambs (4 months of age) were fed for 18 weeks, starting in August, a ration that restricted growth (group R), the same diet ad libitum (group F) or a restricted diet for 8 weeks followed by ad libitum feeding (R/F). Seasonal increases of plasma FSH, testes size, sexual skin flush and plasma testosterone occurred with similar timing but reduced magnitude in group R compared with group F lambs.
