Boric acid in a dose of 1 g/kg was given orally to albino rats for a period of 2 weeks, daily. Changes in the nucleus and the cytoplasm of both the spermatozoids and spermatides were revealed at the early stages of their formation. The appearance of numerous multinuclear cells with an even and odd number of nuclei (from 2 to 10 and over) was noted. The formation of multinuclear cells can be apparently attributed to the action of boric acid on the prolonged processes of meiotic division of the spermatogenic epithelium cells (spermatocytes, spermatides).
