Edinburgh panda's hormone levels return to normal
Efforts to breed the UK's only female panda have failed once again as Edinburgh Zoo confirms Tian Tian is no longer pregnant.
"All data gathered since conception took place pointed to a pregnant panda likely to carry to full term, sadly this did not happen," explained Iain Valentine, director of the zoo's giant panda project.
"There is no evidence she had a miscarriage, so late reabsorption of the foetus could have occurred."
The panda was artificially inseminated in April of this year. It was her second unsuccessful pregnancy, as a previous attempt in 2013 also failed.
Mr Valentine commented: "Although Tian Tian has not successfully given birth, it is important for her individual biology and for the future of giant panda conservation across the globe that we tried."
Staff continue to monitor the panda and say she is in good health. Data and procedures from this year and last will be reviewed.
The outdoor viewing area of the panda enclosure has once again been opened. Pre-booking will not be required to see the pandas this week, however the zoo recommends booking online if you plan to visit between September 29 and October 31.
