Partner's lifestyle may help infertile obese females conceive

Improving the diet and weight of males could have a significant impact on the likelihood of their female partner becoming pregnant if they are obese and infertile, a new pilot study suggests.

Preliminary research results, which will be presented at the annual meeting of the Endocrine Society, found a "significant relationship" between men making changes to their diet and weight and conception.

Lead author Matea Belan, a graduate student from the Faculty of Medicine and Health Sciences at the University of Sherbrooke in Quebec, said it was most surprising that this association occurred independently of lifestyle changes from the female.

Classed as being unable to conceive for 12 months, infertility affects between 12 to 16 per cent of people in Canada. Although weight loss is known to be linked to better fertility in women, less is understood about how the impact changes to the male's lifestyle can have.

In their pilot study, the team examined couples who were referred to the fertility clinic. Men in couples who conceived were significantly more likely to lose more weight and eat more breakfasts or 5 or more daily fruits and vegetables than men in couples who did not conceive.
