In a dominant lethal assay, CD1 male mice
were exposed to up to 50000 ppm HFC 134a for 5 days. After the last
exposure, each male was housed with 2 virgin females for 4 consecutive
nights. Further matings with new females were conducted at weekly
intervals for a total of 8 times. The study indicated that HFC 134a did
not affect male fertility or cause mutagenic effects through sperm.
