decreased testes secretion ( J:278979 )

• in culture, primary Leydig cells from 50-day-old males show a drastic reduction in basal testosterone as well as severely impaired testosterone synthesis in response to stimulation with hCG (human choriogonadotropin), dibutyryl(Bt2)cAMP (a permeable cAMP analog), 22OHC (22-hydroxycholesterol) or P5 (pregnenolone)
