Day, P A

Six beagle dogs were exposed to a total dose of 183 R of gamma radiation at a dose rate of 1 R/day, while three other dogs were exposed to a single dose of 100 R. Weekly semen analysis was performed on all irradiated dogs plus four nonirradiated dogs. Semen volume, sperm concentration, total sperm count, sperm motility and sperm head morphometry were examined. Dogs exposed to chronic radiation showed a severe decline in sperm numbers, detected after seven weeks of exposure. Sperm concentration and total sperm count were the first parameters affected and were the only parameters consistently affected. The dogs exposed to 100 R as a single dose, did not show a significant decline in sperm numbers. During a 36 week recovery period, the chronically irradiated dogs did show a slight increase in sperm numbers, but they never approached pre-exposure levels.
