Like humans, dogs are occasionally born with birth defects. At the Baker Institute for Animal Health, Dr. Vicki Meyers-Wallen studies XX DSD, a disorder of sexual development in which affected puppies have normal female sex chromosomes (XX) but are born with masculinized genitalia and are often infertile or sterile. Dr. Meyers-Wallen’s work focuses on tracking down the genetic reasons for XX DSD so that the disorder can be avoided or eventually eliminated from purebred dogs.
