The International Olympic Committee insist there is no evidence to support claims that some of China's female gymnasts at the Games were underage.
Largely due to a blog investigation which unearthed online documents suggesting some gymnasts were too young, the International Olympic Committee asked the sport's governing body, the International Gymnastics Federation, to look into the claims.
However, the IOC said: "So far, everything that has been received demonstrates we have no problem for the eligibility of the competitors."
The Chinese women won gold in the all-round team event and, significantly for Great Britain, He Kexin and Yang Yilin both won medals in the uneven bars - a discipline which saw Briton Beth Tweddle finish fourth.
He, who won gold, and bronze medallist Yang are among those linked to the story, with reports suggesting they could be just 14. Gymnasts need to celebrate their 16th birthday during Olympic year to be eligible.
Satisified
IOC spokeswoman Giselle Davies said the IGF had been asked to investigate "what have been a number of questions and apparent discrepancies" and were satisfied with their reply.
"We believe the matter will be put to rest and there's no question on the eligibility," she said. "The information we have received seems satisfactory in terms of the correct documentation, including birth certificates."
Some online records - including some from the General Administration of Sport of China - suggest three Chinese gymnasts, He, Yang and Jiang Yuyuan, could be underage.
