Lori Schwacke, a NOAA scientist, said the dolphins' hormone problems could not definitely be tied to the oil spill but were "consistent with oil exposure."
Over the same period of time, NOAA says 714 dolphins and whales have been found stranded from the Florida Panhandle to the Texas state line, with 95 percent of those mammals found dead. Normally, the region sees 74 reported dolphin deaths a year.
