The University of Science and Technology in Shenzhen said he did not know the research project and will now launch a research.
And other scientists say that the statements are true, the Professor has gone too far, trying to justify healthy recreation.
Professor Robert Winston, Professor Emeritus on Opportunity of Opportunity and Professor of Science and Society at Imperial College London, said: "If this is a false report, it is scientific and irrelevant misconduct.

Professor Julian Savulescu, a specialist at the University of Oxford, said: "If it's true, this test is very spectacular. The minds were healthy – there are no known diseases.
"Generation is self-tested and is still associated with targeted tenants, which can cause genetic problems in the early and later stages of life, and include cancer development.
"These exams produce healthy normal children to genital behavioral risks for any necessary benefit."
Scientists say that a single-generation parent generator can be easy to use, but more studies and measurements are needed before they can do it.
Dr Yalda Jamshidi, a humanitarian expert in St George's, University of London, said: "We do not know much about the long-term effects, Some would have trials on people to simply avoid a state for morally and morally improperly improperly improvised.
