  • Title: Androgen binding protein levels and FSH binding to testicular membranes in vitamin A deficient rats and during subsequent replenishment with vitamin A.
    Author: Unni E, Rao MR.
    Journal: J Steroid Biochem; 1986 Oct; 25(4):579-83. PubMed ID: 3773529.
    Abstract:
    ABP levels in the testes and epididymides of vitamin A deficient-retinoic acid maintained rats were only 20 and 6% respectively as compared with those in normal rats. The number of FSH receptors in the testes of vitamin A deficient rats, as measured by [125I]ovine FSH binding to isolated testicular membranes, was only 40% of that in the testes of normal rats. Supplementation of retinyl acetate to these vitamin A deficient rats for 16 days resulted in restoration of the number of FSH receptors to normal levels. On the other hand, ABP levels were restored to 32 and 34% only in the testes and epididymides respectively.
