Effect of High Altitude Hypoxia on the Postnatal Development of Rat Testis: Histological and Histometric 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, and up to the third week of postnatal dev...
