EDINBURGH Zoo's male giant panda may be experiencing sympathetic pregnancy symptoms.

Yang Guang was off-show yesterday and may have been having similar symptoms to that of his partner Tian Tian who was revealed as pregnant last Friday.

Zoo officials said the panda was "feeling under the weather" on Tuesday and spent most of the day away from the public.

His poorly condition may be due to Couvade Syndrome which is the medical term for sympathetic pregnancy.

The syndrome causes male partners to experience the same feelings as the mother including sickness and hormone change.

In humans it can cause morning sickness, disturbed sleep patterns and in more extreme cases even labour pain.

Edinburgh Zoo's website has been crashing this week as thousands try to access 'panda-cam' to try and catch the first glimpse of a baby panda.

But some zoo visitors took to social media to express their disappointment at not being able to see the pandas that arrived in 2011 first hand.

They were annoyed the zoo still took bookings to view the pandas despite not being able to see them.

Hannah Whitford wrote: "We got tickets for the 11am viewing and were told it was closed.

“We were told at 1pm to go back at 3:30pm.

“We got into the viewing area at 4pm and were crammed in to see nothing but an empty viewing area.”

Whilst another visitor thought the Edinburgh Festival's closing ceremony may be behind the no show.

Dot Thompson wrote: "Not a panda to be seen.... traumatised by Monday’s fireworks. Never mind."

And just this week adorable photos were released after a baby panda was born at a zoo in France.

An Edinburgh Zoo spokeswoman said: "The outdoor viewing area of the giant panda enclosure has been open to the public all day, with Tian Tian able to move freely between her indoor and outdoor areas as normal.

"Yang Guang was off-show as he was feeling a little under the weather but now has full access to his outdoor area."

Panda experts at Edinburgh Zoo carried out the artificial insemination on the female panda late last year.

Tian Tian had previously given birth to twins in China but all previous attempts to produce a cub here have failed.

If the cub is born in Edinburgh it could bring as much as £30 million to the local economy as visitors flock to see the baby.

However, the cub would be returned back to China when it reaches the age of two.
