Walnuts 'improve sperm health'
By Anna-Marie Lever
Health reporter, BBC News
Could two handfuls of walnuts a day keep the fertility doctor away?
Sperm 'not affected by lifestyle'
Diet 'linked' to low sperm counts
Chemicals 'damage male fertility'
Eating around two handfuls of walnuts a day improves sperm health in young men,
a study in the journal Biology of Reproduction suggests.
Sperm shape, movement and vitality improved in men who added walnuts to their
diet over 12 weeks.
The fatty acids found in these nuts are thought to have helped sperm
development. It is not known if this would help improve male fertility.
About one in six couples are infertile, with 40% of these due to a male factor.
Dr Allan Pacey, senior lecturer in andrology at the University of Sheffield
said: "It would be relatively easy to poke fun at studies like this, but there
is increasing evidence to show that aspects of a man's diet can affect the
number and quality of sperm produced by his testicles."
The researchers say the next step is to work with couples who are attending
infertility clinics to determine if placing sub-fertile men, with poor semen
quality, on a walnut diet results in better success conceiving.
Walnuts provide a rich source of omega-3, which we suspect may have been
responsible for the improvements we observed.?

It is thought that infertility in men may be a result of too few sperm being
made, or that the sperm have poor swimming ability, size or shape.
Walnut supplement
This study involved 117 men between the ages of 21 and 35, who were divided
into two groups. One group added 2.6 ounces (75 grams) of whole-shelled walnuts
to their daily diet.
The other group continued their usual diet but avoided eating tree nuts. Both
groups ate a typical Western-style diet.
Lead author, Prof Wendie Robbins from UCLA's Fielding School of Public Health
said: "We found a significant improvement in sperm parameters in the group that
consumed the walnuts.
Healthy sperm
"The men who ate no tree nuts saw no change."
Sperm quality improved in terms of concentration, vitality, movement, shape and
chromosome abnormalities.
Dr Pacey said: "The study has been well executed and my only criticism would be
that the men in the walnut-eating arm of the trial could have altered other
aspects of their behaviour to give the results shown in the paper.
"A better trial would be to produce tablets of walnut extract that looked
identical to a placebo so that the study was completely blind.
"In spite of this, the results of the study show a small but statistically
significant improvement in sperm health."
These benefits may be down to the fatty acids in the nuts.
Co-author Catherine Carpenter, from the UCLA Centre for Human Nutrition said:
"Walnuts provide a particularly rich source of a-linolenic acid, a natural
plant source of omega-3, which we suspect may have been responsible for the
improvements we observed."
The walnuts for the study were supplied by the California Walnut Commission and
the study was funded by the UCLA Fielding School of Public Health's Centre for
Occupational and Environmental Health.
