Influence of Vitamin B12 Upon Vaginal Patency in the Rat

Abstract

Summary

The onset of sexual maturity in female rats, as measured by vaginal patency, was found to be delayed in vit. B₁₂-dencient animals as compared to vit. B ^-supplemented littermates when their mothers were fed a B₁₂-dencient ration during lactation. No such differences were observed when the mothers were fed B₁₂ during lactation. The nature of the carbohydrate and protein in the ration was found to have an effect on the differences observed.
