A giant panda called Lu Lu has become an internet sensation after smashing his species’ sex record with a seven-minute, 45-second lovemaking performance.

With the panda average ranging anywhere from 30 seconds to five minutes, Lu Lu has won internet acclaim and been dubbed ‘The Enduring Brother’ by zookeepers at the Sichuan Giant Panda Research Centre.

Lu Lu and his partner Zhen Zhen were pitted against another panda couple, Yi Bao and Jin Xin, who only managed one minute and 20 seconds.

Getting pandas pregnant is notoriously difficult.

Firstly, zookeepers have found that pandas rarely show interest in mating. Some males have even been dosed with viagra and couples shown porn in an attempt to get them in the mood.

Secondly, a female is only in heat once per year for a maximum of 25 days, and only receptive to mating for two to seven of these days, and only fertile for around 26 hours.
