Tian Tian, A giant panda lent by China to Edinburgh Zoo, is believed to be pregnant and could produce a cub by the end of the month, the zoo said.

LONDON (AP) — A female giant panda at a Scottish zoo appears to be finally pregnant after months of dashed hopes and anticipation.

Edinburgh Zoo said Tuesday the latest scientific data it has suggests that Tian Tian — Chinese for Sweetie — has conceived following artificial insemination in April, and may give birth at the end of the month.

Experts are closely monitoring the hormone and protein levels in the animal’s urine on a daily basis, but officials cautioned they would not be certain until Tian Tian gives birth.

‘‘This is all very new and complex science and we still have a bit of time to go yet, as like last year, the late loss of a cub remains entirely possible,’’ said Iain Valentine at the Royal Zoological Society of Scotland.

Tian Tian became pregnant last year, also after artificial insemination, but appeared to have reabsorbed the fetus late term. Before that, she was reluctant to mate with male companion Yang Guang — Sunshine — despite encouragement from zoo officials.

Giant pandas have difficulty breeding and their pregnancies are notoriously difficult to follow because the animals experience ‘‘pseudo-pregnancies’’ — their behavior and hormonal changes do not indicate for certain whether they are pregnant or not.

The mammals’ fetuses do not start to develop until the final weeks of gestation.

Tian Tian and Yang Guang, both aged 10, arrived from China in 2011. They are the only pandas in Britain.
