Vitamin B12 and potential fertility in male lactovegetarians

  • Rashmi Hirwe (a1), V. S Jathar (a1), Shantha Desai (a2) and R. S Satoskar (a2)

Semen and serum vitamin B12 levels in Indian lactovegetarian and non-vegetarian subjects were estimated along with routine semen examination. Lactovegetarians had distinctly lower serum and semen vitamin B12 levels than the non-vegetarians. However, in normal and oligospermic subjects the ratio of semen vitamin B12 to serum vitamin B12 in the various diet groups was not significantly different and was always greater than one. In azoospermic subjects the serum vitamin B12 levels were always higher than the corresponding semen vitamin B12 values. Although semen vitamin B12 content was related to serum vitamin B12 level and sperm concentration in the normal and oligospermic groups. Further, in healthy lactovegetarians with low serum and semen vitamin B12 content and oligospermia, treatment with hydroxocobalamin produced no significant improvement in semen quality.
