Win 18446 (200 mg/kg, Orally for 4, 8, and 16 weeks) significantly reduces intratesticular concentrations of retinoic acid, severely impaired spermatogenesis, and caused infertility.
Animal Model:
Six-month-old male New Zealand white rabbits.
Dosage:
200 mg/kg.
Administration:
Orally for 4, 8, and 16 weeks.
Result:
Resulted in marked suppression of testicular weight over time.
Dramatically suppressed spermatogenesis.
Significantly reduces intratesticular concentrations of retinoic acid and Stra8 expression and very severely suppresses spermatogenesis and fertility.
