A recent research study published in the journal Fertility and Sterility has given support to nutritionists who have long advised that eating a healthy diet is important for good sperm quality for couples trying to get pregnant. In essence, men who eat a lot of fruit and vegetables have higher quality sperm that also swims faster.

The Spanish scientists found good quality sperm is a direct result of a diet high in antioxidants found in fruit and vegetables and especially in peppers, citrus fruits and spinach. Alternatively, sperm are fewer and slower in men who eat few antioxidants and instead feast on meat and full-fat dairy products such as cream or cheese.

Lead researcher Jaime Mendiola, of the University of Murcia, Spain, said: “A healthy diet is not only a good way of avoiding illness, but improves the quality of semen.

“Men who eat lots of meat and full-fat dairy products have much poorer quality sperm than those who eat lots of fruits, vegetables and low-fat dairy products. People who eat more fruits and vegetables are ingesting more antioxidants, and this is the important point.”

The scientists spent four years studying men in two fertility clinics in Spain to see if anything in their diets or exposure to pollution at work was making it difficult for some to father children.  The study included 61 men, 30 of whom had reproductive problems and 31 who didn’t.

Many women who are worried about their f ertility will use an ovulation predictor kit to see if they are ovulating ok. A common query that we encounter is about how reliable the kits are. If the result appears postive, does that necessarily mean that ovulation has occurred?

The thing to remember is that ovulation kits predict impending ovulation by detecting the surge of a hormone called LH, or luteinizing hormone. LH is the catalyst that thrusts the egg out of the ovary during ovulation. When the basal body temperature rises as a result, ovulation has occurred because after ovulation, the leftover follicle (the corpus luteum) that encased the egg in the ovary starts producing progesterone, a heat-inducing hormone.

So, the progesterone causes the basal body temperature to rise, usually a day or two after ovulation, and there is usually a two or three day delay from the LH surge to the temperature rise. The LH surge happens first, then ovulation, and then the temperature rise.

This means that it is possible to have an LH surge and then still not ovulate.  If this happens, the ovulation predictor kit will register positive but the body temperature will not rise to a sustained higher level. This is why it is a good idea to track the temperature as well as use the ovulation predictor kit.

Some women who are having trouble getting pregnant get worried at the thought of all the drugs involved in assisted reproduction treatments like IVF. However, it is possible to do IVF in a natural cycle without hormonal stimulation.

A natural IVF cycle basically involves collection of a naturally produced egg, followed by fertilisation in laboratory and subsequent replacement of the embryo. It is less expensive and less invasive than a normal IVF cycle and in addition, because no drugs are used to stimulate the ovaries, it can be easily repeated in following cycles if unsuccessful after the first go.

The only thing is that success rates tend to be low compared to stimulated cycles. However, for women who don’t want to take conventional fertility medicine, or who can’t take fertility medicines, this treatment could be an option to consider. For example, women who are ovulating and have damaged tubes may wish to try a natural cycle of IVF before moving on to stimulated IVF.

Obviously, the natural IVF cycle fits well with the natural approach of acupuncture. No research has yet been done to see if the natural IVF success rates are improved if women also have acupuncture treatment, but based on previous studies of acupuncture and IVF it could be an interesting study to look at.

It takes two to make a baby, and if a couple is infertile the problem is often due to a combination of male and female factors.

Three key measures for sperm health are sperm count (quantity), sperm motility and sperm morphology. The correct medical name for low sperm count is oligospermia, and there are some key nutritional guidelines that can help to improve this condition.

Most people have heard about ‘free radicals’, chemical fragments that contribute to the toxicity of various drugs, aging, and the development of cancer. What one might not know is that free radicals tend to be abundant in the semen of 40% of infertile men. In fact, free radical, or oxidative damage to sperm is one of the major causes of oligospermia.

So how to reduce damage from free radicals? This is where anti-oxidants can work their magic, and some of the best anti-oxidants are vitamin C (found in citrus fruits), beta-carotene (found in red, orange and yellow vegetables) and vitamin E (found in nuts and green leafy veg).

Smoking reduces vitamin C throughout the body - this is one reason why smokers are more likely to have low sperm counts, but non-smokers will benefit from increased vitamin C as much as smokers.

Vitamin E is the main anti-oxidant in sperm membranes, and can enhance the ability of the sperm to fertilize an egg in vitro.

In addition to good levels of antioxidants, it’s important to have the right kind of fats and oils, so saturated or hydrogenated fats should be avoided and replaced with the good Omegas (3, 6 and 9) found in oily fish and seeds like flax, pumpkin and sunflower.

Finally, the most important trace mineral for sperm production is zinc. Zinc deficiency decreases testosterone as well as sperm counts, and studies have shown that men with oligospermia tend to have lower levels of zinc.  15mg a day should do the job, and zinc can be found in high quantities in oysters and other shellfish, chickpeas, baked beans and pumpkin seeds.

If fertility consultants had a way to check collected eggs for chromosome abnormalities, they would be able to reduce the chances of miscarriage or birth defects after implantation. Recently, in Nottingham, doctors collected 9 eggs from a woman undergoing treatment and were successful in using a new screening technique to help identify the best eggs with intact chromosomes. The 41 year old woman had previously had 2 miscarriages and 13 subsequent unsuccessful courses of IVF, but fell pregnant after the cycle that used the new screening process.

The process could also potentially be helpful to doctors wanting to reduce the number of twins and triplets as a result of IVF, as it could improve the chances of selecting the most promising embryo and reducing the need to implant 2 or more in any given cycle.

The technique has not yet been subject to full rigorous trials so will probably not be widely available for some time yet, but seems a promising development in fertility medicine.
