Ejike Orji, chairman, Association for Advancement of Family Planning, says consensual sex boosts the immune system, keeps the skin glowing and reduces stress.
The physician made the disclosure in an interview with NAN on Wednesday in Abuja.
Orji defined consensual sex as one that is permitted by both sexes in the act.
He said the endorphins released during sex helps in boosting the immune system of human beings.
Orji said couples who engage in regular consensual sex were likely to live longer than those “who do not engage in it”.
He noted that the endorphins that are released during sexual intercourse also helps in the improvement of all the organs in the body, saying that it could make a person look younger.
He said research conducted by some scientists in London revealed that men and women, who had an active sex life looked between five and seven years younger than their actual ages.
The expert said the study also showed that men, who had sex at least twice a week, were up to 45 percent less likely to develop life-threatening heart conditions than men, who had sex less than once a month.
He noted that the benefits of sex could be both physical and emotional, saying those who indulge in regular sex were likely to display an increase in cranial nerve growth.
According to him, cranial nerve growth is crucial for mental alertness and improvement in brain functions.
Orji, who said that sex could reduce the risk of prostate cancer development, emphasised that men who had more sexual intercourse were less likely to develop prostate cancer.
“I, therefore, enjoin couples to engage in consensual sex because it helps to reduce stress as well as provide full body exercise.
“Having sex involves all the muscles in the human body, which thereby helps in the improvement and function of the body system,” he said.
