Reversible Effect of High Altitude on Rat Testis Morphology and Spermatogenesis: Histological and Ultrastructural Study

The study was carried out at two different altitudes in the southern region of Saudi Arabia: Abha, 2,800 meters above sea level, the high altitude (HA) area and Jazan, 40 meters above sea level the low altitude (LA) area. Following exposure to high altitude, testes of rats revealed various types of...
