THE EFFECT OF GOSSYPOL ON K~+, Na~+ AND TESTOSTERONE IN SERUM AND RAT TESTIS FLUID IN RATS / 中国药理学通报

ABSTRACT

Feeding adult male rats with gossypol acetic acid at a dose of 15 nig/kg/day for 50 days led to infertility. Spermatogenesis and sperm motility were impaired ( table 1 ) . However, testosterone, K+ and Na+ concentsrations in serum and RTF were found to be unchanged (table 2, 3 ) . It suggests that at low antifertility doses gossypol disrupts spermatogenesis in the seminiferous epithelium without affecting testosterone, K+ and Na+ secretion and translation in testis.
