Yes you did read correctly…..


Could two handfuls of walnuts a day improve the sperm shape, movement and vitality of your sperm?
It seemed appropriate to write about this as September 29th in France is the day people harvest their walnuts and that is what I shall be doing during the next week.

he tao ren | 核桃仁 | Juglandis Semen:walnut

This Chinese herb has been used for many hundreds of years in traditional Chinese medicine (TCM) to reinforce and Tonify the Kidney and Lung Yang. In Western terms this means that if you are ageing, a cold person, tendency to being overweight, backache, knee pain, breathlessness, constipation and infertility. These type of herbs particularly walnuts can gradually ( over a minimum period of 3 months) improve these problems along with other other lifestyle measures.
The Walnut tree is a common sight in the Dordogne,France and it is interesting that it always grows alone or with other walnut trees and has been has been harvested for many years for the nuts or taken to mills to make walnut oil,which is used for salad dressing and is very high in Omega-3 fats with all the health benefits.
imageThe mills are at intervals along the Dronne and are often in the shape of a boat(bateau) and the wiers associated with these mills make exciting canoeing! Most are not in use but there a few which still produce walnut oil. It is possible to take the harvested nuts,after drying them over the winter, to the mill and collect the oil at a later date.Sitting by an open fire cracking nuts in the winter months,watching a good film can be pleasant winter pastime. Old dordogne kitchen tables have large dents in the table surface after years of family nut cracking with a mallet. The new nutcracker is much easier…
imageBut since I read about a small study carried out in Californis and written up in the journal Biology of Reproduction suggesting that eating around two handfuls of walnuts a day improves sperm health in young men harvesting walnuts has a new meaning.
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 shape, movement and vitality in men who added walnuts to their diet over 12 weeks.”
“The men who ate no tree nuts saw no change.”
The fatty acids Omega-3 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.
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.
When I resd this I wondered whether it was a signifant result but 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.”

Moreover,all those young men that need to improve the health of their sperm and potentially their fertility

*Avoid cigarettes and illicit drugs, especially anabolic steroids
*Avoid exposure to toxins such as pesticides and heavy metals
*Limit alcohol intake
*Eat a healthy diet and maintaining a healthy weight
*Take care to keep your scrotum cool, because heat slows sperm production. Avoid hot baths and hot tubs, wear boxers instead of briefs, and avoid pants that are tight or restrictive.
