The investigation by the Pew Research Center in the US also found that women are more likely than men to see faith as a "very important" part of their life.
The research shows Christian women in the UK are 16 per cent more likely to pray every day.
Responding to the figures on Premier's News Hour, to Dr Jonathan Oloyede, leader of the National Day of Prayer and Worship said he thinks many men do engage in prayer, but they are less likely to admit it.
He's calling on the Church to do more to address the 'gender pray gap'.
He said: "If the Church sets up a construct that allows men to be functional, to be involved and to feel affirmed and appreciated then you'll find that more men will get involved in the Church and with God."
Dr Jonathan Oloyede went on: "I think more men pray than they probably admit to.
"More women will openly confess to pray more - when you pray a lot of men will see prayer as weakness, as leaning on more of an emotional, spiritual crutch."
American women also were also shown to be more likely than American men to say they attend religious services at least once a week (40% vs 32%).
