Professor Adegboyega Fawole of the University of Ilorin Teaching Hospital, has advised against the practice of oral sex.
Mr. Fawole said the Human Papiloma Virus (HPV) has been found in the throat of people engaging in oral sex.
The professor, who is of the Department of Gynaecology, UITH, told the News Agency of Nigeria in Ilorin on Tuesday that HPV was mostly sexually transmitted.
He said the virus risk the spread of cervical cancer and could cause genital warts and anal cancer.
Mr, Fawole further advised people to ensure they go for regular screening and check-up to guard against cancer of any kind.
“Oral sex has been linked with an increased risk of acquiring HPV infection in the mouth and with an increased risk of developing oral cancers that are caused by HPV.
“However, sex in general has also been linked with these risks,” he said.
The gynaecologist warned that those engaging in oral sex were twice more likely to have oral HPV infection than those who did not engage in oral sex.
He however, said there was no need for individuals in monogamous relationships to restrict their sexual activities if the pair was in good health.
