Men have been sadly ignored in the fertility world for far too long. Vets and farmers know the benefits of feeding their animals a diet rich in specific nutrients. In fact, there has probably been more research done on bull and stallion sperm than human sperm (see bull story below). Good sperm means money. However, new research is highlighting the importance of the male role and I am lucky enough to work with some of the best male fertility specialists in the UK. My experience in that field helps me to recognise the need for referral to a specialist and I have studied the relationship between male sub-fertility, obesity and IVF success for my final MSc research project.


An Indian bull, whose semen is worth $3,000, has a meticulously planned diet and vitamin plan. If it works for bulls, it works for human men! But I do recognise that the last thing a man wants is to give up time to discuss his sperm and his diet with a complete stranger – hell! So, I really try to make our consultations easy, laid back, factual, evidence-based and interesting. And I do not make you give up everything, sometimes there is a bit of a time limit to IVF for example so the plan is a little more focused, and sometimes you may just be trying naturally. But couples still need to have a life, a coffee, a pint of beer, a glass of good wine, the gym; good endorphins are essential. There are no outright bans. But it’s still a project, and a team effort. After all the DNA of an embryo is 50% from the man and making the sperm as good as possible is the aim; you want to tick all the boxes and give it your best shot, and nutrition can dramatically improve sperm quality.

Case Study

Here is a case study showing results of sperm tests before and after a nutritional consultation with me. This was a very interesting case as the person concerned wanted to become a sperm donor, but unfortunately there were several problems with the sperm and he was told he couldn’t. However, he was extremely determined and highly motivated and was willing to completely take on board everything, and so it really was fantastic to see such a dramatic change in the sperm quality. He subsequently was accepted as a donor. And recently he has married and has just had a baby!

Before consultation, March 2010  This sample was viscous, showing a slightly high pH. If semen remains too thick this may affect the ability of the sperm to move. If the semen is too alkali it may indicate a problem with the prostate gland which should produce seminal fluid that is slightly acid, or a lower pH. Motility was poor with not enough sperm swimming in a straight line (progressively). There were also some anti-sperm antibodies present in the sample. These can prevent fertilisation by sticking to the sperm, particularly the head. Sperm then can’t recognise the egg or penetrate it, and they also stick to each other.

The vast majority of the sperm in this sample were abnormally shaped, which again causes problems with adherence to and penetration of the egg. However just how many abnormal sperm you have before fertilisation is severely affected depends on the criteria used – the WHO define >85% (so <15% normal) as causing problems, but using strict Kruger criteria > 95% (< 4% normal) is believed to severely impair fertility. And of course, it depends on the count too. If you have a very high count you can afford to have more abnormal sperm than if you have a lower count. This client had a moderate count of 37 million, above the 15 million defined as being in the ‘fertile’ range.

After consultation, October 2010  2010  Here you can see a massive improvement.  Although the semen is still viscous and there is debris, the pH has dropped. The count has almost doubled to a very satisfactory 64 million and the motility is now well within the normal range. There are no longer anti-sperm antibodies and the morphology is within the normal (Kruger) range. The client was absolutely delighted as you can imagine, and went on to donate as many times as he was permitted.

The Mediterranean Diet

This is the diet that is the cornerstone for health for everyone, and research has shown that it is especially relevant for strong, healthy sperm. Full of strongly coloured vegetables, fruit, seeds, wholegrains, pulses, fish, herbs, olive oil and a little red wine.
