PSVII-6 - Effect of summer months on testicular histoarchitecture and spermatogenesis in Dezhou donkey: A histological study

Abstract: This study aims to illustrate testicular histoarchitecture and progression of spermatogenesis in Dezhou donkeys during summer months. For experiment, 8 male Dezhou donkeys having body weight 260 + 20 kg and aged 2 years were analyzed using microscopy and Jonhson’s score. Based on acrosomal system, Dezhou donkey spermatogenesis comprised of XII stages. Various types of spermatogonia: A_1, A_2, A_3, B1 and B₂ were observed along with undifferentiated spermatogonia (A_und). Testicular histoarchitecture during spermatogenesis, seminiferous tubules diameter (ST), ST height ((µm), Luminal tubulaR diameter (µm), No. of ST/field, No. of germ cells along with normal Jonhson’s score illustrated that stages of spermatogenesis and testicular histoarchitecture of adult Dezhou donkeys are not affected during summer months.
