Scientists hope to study the effect of cosmic rays on the pig sperm

China is planning to study the effects of outer space on sperm by sending the semen from pedigree pigs into orbit.

Some 40 grams of pig sperm will be taken on board the Shenzhou VI spacecraft for its October launch.

Some of the sperm will be kept outside the spacecraft's biological capsule and some inside, according to China's Xinhua news agency.

Surviving sperm will be returned to earth and used to compare the effect of microgravity on the semen.

The pigs chosen are a breed called Rongchang, named after an area in the southwest of the country and famed for their physique and for the quality of their meat.

Agricultural experts hope to use the sperm to fertilise pig eggs back on earth and monitor the effects of the journey to space.

China's first manned space flight two years ago made it the third country able to launch a human into space on its own, along with Russia and the United States.

During the mission two astronauts will orbit the planet five or six times.
