Pressure on men to come up with the goods at precisely the right time of the month for women trying to conceive is causing infidelity and even impotence, according to research.
One in 10 men have succumbed to an affair because of the pressure of women’s narrow window of ovulation and four out of ten men have even blamed their impotence on the stresses it causes them.
Research, carried out in South Korea found that men with previously no sexual problems were experiencing problems producing testosterone which affects their libido.
As a result, experts advise abandoning strictly timed sex after three months for a break before resumption.
“Timed intercourse seems to impose a substantial degree of stress on male partners including erectile dysfunction and in some cases, causing them to seek extramarital sex,” scientists wrote in the Journal of Adrology.
