A Professor of medical science at the University of Ilorin, Musa Yakubu has given reasons why having sex early in the morning is essential to human health.
The professor said such activity lowers blood pressure and reduces risks of heart attack.
The Prof. Yakubu who teaches in the Department of Biochemistry made the assertion in a paper entitled, "Knocking Down the Barriers to Four O'Clock Activities and Reproductive Inadequacies", presented at the 163rd Inaugural lecture of the university, recently.
He also advised that having sexual intercourse, three to four times a week was good for love life.
According to him, "Research has shown that sex boosts immune system by stimulating the body's first line of defence and production of immunoglobulin A (IgA), against cold and fever.
"Antibodies are proteins made by the immune system to fight bacteria, viruses, and toxins. Prof. Yakubu said that sex also regulates menstruation in women by influencing the levels of lutenising hormones that controls menstrual period and promote better sleep."
According to him, the act of sexual intercourse also release the feel-good chemical, known as oxytocin, which enhances closeness with one's partner and makes people feel happier for a longer period of time.
"Lovemaking of about 20 minutes reduces 150 calories."
The professor of Biochemistry postulated that sex is the most powerful creative force given to human by God for pleasure and deep companionship.
He, however, noted that any marriage in which the man or woman could not enjoy sexual intercourse or satisfy their partner in bed was a dead marriage. He also said that lack of sexual satisfaction had led to the collapse of many marriages in Nigeria, and urged couples to seek for solutions to the problem.
"Sexual and reproductive dysfunctions are common among men and women in Nigeria, which necessitates regular screening and check-ups," he said.
He also said that traditional medicines have been authenticated to cure sexual dysfunctions.
