title: Effect of acute chloroquine treatment on prostaglandin- and gonadotropin-stimulated testosterone secretion of rat testis.
abstract: The effect of chloroquine injection to rats on in vitro-testosterone secretion stimulated by human chorionic gonadotropin (hCG) and prostaglandin E1 (PGE1) was studied. Rats were injected for 5 days with chloroquine phosphate. Testosterone secretion was stimulated by hCG or PGE1 for 3 h in the removed testis and was measured by radioimmunoassay. Chloroquine treatment in vivo does not seem to have any demonstrable effect on testosterone secretion stimulated by hCG or PGE 1 in prepubertal as well as in the postpubertal rats. However, in pubertal rats chloroquine treatment inhibited testosterone secretion in hCG-stimulated testis.
