Giant Panda Mei Xiang may be having a Baby Panda!

Smithsonian Conservation Biology Institute (SCBI) scientists have confirmed a secondary rise in giant panda Mei Xiang’s (may-SHONG) urinary progesterone levels. The slow rise started July 20 and indicates that she will either have a cub or experience the end of a pseudopregnancy within 30 to 50 days. Scientists have been carefully tracking Mei Xiang’s hormone levels since she was artificially inseminated April 26 and 27. The inseminations used frozen sperm collected from Hui Hui, a panda living in China, and fresh sperm collected from the National Zoo’s Tian Tian (tee-YEN tee-YEN).
