Men who suffer fertility problems because of low sperm quality may be able to improve their chances of fatherhood by having sex every day, research has suggested.
While those trying for a baby are often told to refrain from ejaculating too often to protect their sperm count, Australian scientists have shown that this can be counterproductive and may lower male fertility.
Among men whose fertility problems stem from genetic damage to their sperm rather than a low sperm count, abstaining from sex can make their difficulties worse, research led by David Greening, of Sydney IVF, has shown.
The pilot study of 42 men whose sperm showed significant DNA damage found that daily ejaculation reduced this by 12 per cent. While the results are preliminary and no direct effect on fertility has yet been measured, they suggest that certain men could benefit from having sex more often, or from abstaining less before providing semen for use in IVF.
