Determining Pregnancy

Giant panda Mei Xiang undergoes an ultrasound exam to test for pregnancy on March 8, 2010. Veterinarian Jessica Siegal-Willott, (L) works the ultrasound probe.

Despite the successful birth of Tai Shan, several attempts by veterinarians to artificially inseminate Mei Xiang from 2007 to 2011 failed.

Because of a giant panda's size and the tendency to have what scientists call "pseudopregnancies," it is very difficult to confirm whether or not a panda is actually pregnant, even after artificial insemination.
