Response from Dr. McGovern
Adefovir is listed as a "category C" drug for pregnant women. That means that the drug should only be used in pregnant women if necessary since there are no studies in pregnant women of this drug.
Studies in rats and rabbits are reassuring, but studies in animals don't always reflect what happens in humans.
As for the male partner, I don't know of any information regarding the concentration of adefovir in sperm. There is a number to call regarding women who are taking adefovir who then become pregnant to register for follow-up. Perhaps your doctor could call on your behalf and get additional information from the company: 1-800-258-4263. Dr. McGovern
