The influence of elevated testicular temperature and scrotal surgery on the number of gonocytes in the newborn pig.
Morphological changes become apparent shortly after birth in the abdominally located testes of the pig. To test the influence of temperature on gonocyte multiplication, scrotal testes of newborn piglets were subjected to continuous artificial heating. It was found that in the young pig during the first 2 weeks of life when the mitotic activity of the gonocytes is high, they are very sensitive to a combination of elevated testicular temperature and scrotal surgery.
