Nutrition Lifestyle and Male Fertility: Part 2


 

The Do’s and Don’ts of Male Fertility








As well as a diet consisting of too much saturated fat affecting sperm concentrations and quality, and the continued links between obesity and fertility problems in men, when advising on how to improve diet and lifestyle factors that may be beneficial to male fertility a number of important areas should be considered:

Don’ts


Alcohol: The Mineral Zinc is found in large quantities in sperm as it helps with sperm formation of it’s cells outer layers and importantly of the tail of the sperm. Alcohol massively inhibits the bodies absorption of Zinc and thus can lead to an increase in abnormal sperm quality and without proper tail formation, an inability to fertilize the egg as a strong well formed tail is needed to penetrate the egg, excess alcohol for males can affect this important function in male fertility.
Men wishing to start a family should consider their alcohol intake, and if starting a family is important to them, considering stopping alcohol maybe well be beneficial for the reproductive system.

Smoking:  Various studies and research over a long period of time have associated smoking and low sperm concentrations in males as well as damaging the sperm cells and affecting mobility that is important for fertilization. With the evidence available, the best thing for men wanting to start a family, and for overall general importance of good health, stop smoking.

Smoking and Alcohol intake can affect fertility in men



Nutrition For Fertility


It is Oxidative or Free Radical Damage that can cause damage to sperm, the more of these free radicals that men are exposed to, say from alcohol or smoking, the more likely they are to have abnormal sperm and low sperm counts.
A diet rich in Antioxidants and most importantly good levels of Omega 3 fatty acids instead the many Saturated fats that cause so much of the damage will be important to proper mobility, structure and quality of sperm and the ability to neutralize Free Radicals to stop them damaging the sperm and affecting fertility.

Antioxidants:  Vitamin C, Vitamin E, Beta-Carotene, and minerals such as Zinc, Lycopne and Selenium, all sourced from foods can help combat Free Radical damage in sperm, as well as being important for everyday general nutrition support.


Vitamin C: Protects the DNA of sperm, and low dietary Vitamin C Levels can lead to fertility issues in men and smoking has the affect of reducing Vitamin C in the body. Antibodies bind to sperm affecting fertility but Vitamin C may be effective against this potential problem.
Best Vitamin C Sources can be found in, Peppers, Parsley, Broccoli, Strawberries, Cauliflower, Papaya, Kale, Kiwi Fruits, Oranges, Cabbages, Tomatoes, Raspberries, Celery, Spinach and Green Beans to name but a few


High Levels of Vitamin C and E from diets are essential


Vitamin E: The main Antioxidant present in Sperm helps to protect from free radical damage to Polyunsaturated Fatty Acids and enhances the quality of the sperm and its ability to fertilize the egg.
Best Sources of Vitamin E include, Sunflower Seeds, Almonds, Blueberries, Spinach, Kale, Olives, Peppers, Swiss Chard, Papaya, Kiwi Fruit, Tomatoes, Broccoli are all great in every day diet and packed full with many other beneficial elements as well as Vitamin E.


Beta-Carotene:  Best dietary sources to boost antioxidants levels that are beneficial to sperm count and quality include, Sweet Potatoes, Kale, Spinach, Carrots, Squash, Cantaloupe Melon, Peppers, Broccoli, Asparagus, Tomatoes, Apricots and Watermelon to name but a few


Zinc:  Important trace mineral for hormone metabolism, sperm formation and sperm motility and any Zinc deficiency, which I men maybe caused not only be poor diet but by excess alcohol which depletes Zinc, can decrease testosterone levels and affect sperm count-all important to male sexual function and the ability to have children.

Best dietary sources of Zinc include, Liver, Beef, Spinach, Lamb, squash, Asparagus, Pumpkin Seeds, Peas, Sesame Seeds and Oysters, one of the richest of all dietary sources of zinc.



Nuts and seeds contain, Zinc, Selenium and Amino Acids

Selenium: An important component that protects cells from Free Radical damage, preventing oxidative stress to act as an effective Antioxidant, and works well alongside, Vitamin E, Vitamin C and Vitamin B3.

Best sources of Selenium found in, Mushrooms, Cod, Shrimp, Tuna, Liver, Sardines, Salmon, eggs, Turkey, Lamb, Oats, Chicken, Sunflower Seeds, Brazil Nuts, Broccoli, Brown Rice and Spinach amongst others.


Lycopene: Is found in high concentrations in male reproductive system and sperm, and in males who have fertility issues, levels seem to be low. It can help boost sperm levels, concentration and motility of the sperm.

Best dietary sources include, Tomatoes, Watermelon, Grapefruit, peppers and Carrots amongst others


Vitamin B12: Important for red cell production and development of nerve cells, a deficiency can see reduced sperm count and motility.

Best dietary sources can be found in, Liver, Sardines, salmon, Beef, lamb, Cod, Low fat Milk and Eggs.



Omega 3 Fatty Acids: As has been pointed out Saturated Fats can decrease sperm concentration and affect motility, however increasing Omega 3 FattyAcids, most commonly found in Oily Fish and some seeds and man plant based foods also, will increase the amount of Poly Unsaturated fatty acids, and as research highlights, the Omega Fatty Acid DHA is vitally important to healthy sperm creation necessary for productive Fertility.

Best sources of Omega 3 Fatty Acids include, Salomon, Sardines, Trout, Pilchards, Mackerel, Scallops, Shrimp, Cod, Tuna, Flaxseeds, Walnuts, Cauliflower, Cabbage, Broccoli, Squash, Spinach, Kale, Strawberries amongst many.



Essential Omega3 Fatty Acids, like Salmon important to fertility and general health


Other Great dietary sources of Antioxidants can be sourced from, Blueberries, Apples, Brussels Sprouts, Cayenne Pepper, Cranberries, Figs, Oranges, Blackberries, Blackcurrants, Green Beans are just some of the many beneficial foods that should play a part in our daily diet, and especially for men considering improving their fertility if wishing to start a family.

General information in regards to male fertility may also consider stress reduction, getting some exercise every day and as well as improving diet and lifestyle, some males may look at specific Nutritional supplements, British company Viridian have a created a specfic nutritional supplement for that purpose.


Amino Acids and Fertility

The Amino Acids L-Carnitine and L-Arginine have also been highlighted as being a vital ingrediants to healthy male fertility, providing a  basis for sperm formation and motility.

Amino Acids are the 'building blocks' of proteins and are essential in the body for repair, maintenance and growth of tissue.

L-Carnitine: An Amino Acid but working as a potent Antioxidant, Carnitine levels are high in sperm, the more Carnitine in sperm, the more motility the sperm has and the more likely successful fertilization may take place.
Low Carnitine levels can impact on sperm development, function and motility
Food sources found in Beef, Chicken, Pork, Avocado, Cod, Asparagus and Eggs to name but a few.
L-Carnitine can be found in many antioxidant or Fertility Nutritional Supplement Formulas.


L-Arginine: Essential for sperm formation and best food sources are found in Walnuts, Brazil Nuts, Beef, Chicken, Turkey, Oats, Chickpeas and Chocolate to name but a few.

Again, like L-Carnitine, L-Arginine is now commonly found as a stand alone Nutritional Supplements, or included in a specific male Fertility supplement as seen below.

Oranges. The Whole greater than the Sum of it's parts!

I take it all of you enjoyed those wonderfully nutritious and beneficial stocking fillers on Christmas Day!
For some of us it was the only thing in our Christmas stocking (weep), but the humble Orange packs a mighty punch, and according to recent research, no amount Vitamin C powder, tablet or whatever supplement form gets dreamt up, can in the end replace the simple, peeling, eating, juicing, squeezing of this natural wonder.

An Orange is NOT just for Christmas!


Researchers have been looking why the WHOLE is so much better for you than it's components when taken separately. That would be the 'sum of it's parts' bit then! 

In essence, researchers are looking at the benefits of supplementation that contains vitamins, minerals and other beneficial substances as close to their original food state as possible, which would hopefully have a greater benefit to health than what already exists in the wider market.
For the Orange that would be to capture the best benefits of peeling and eating an Orange, as well as drinking the squeezed juice.

Eat whole, fruit salad, juice, smoothie!!


The team at Brigham Young University, Utah, USA, have been considering what it is in the nature and structure of the Orange that makes it so much better than current Vitamin C supplementation, BYU assistant professor of nutrition, dietetics and food science, Tory Parker:


"There's something about an orange that's better than taking a vitamin C capsule, and that's really what we're trying to figure out. We think it's the particular mixture of antioxidants in an orange that makes it so good for you."

 
Once reserved for special occasions in medieval times due to their expensive nature, and then becoming a staple for the contents of the Christmas Stocking ever since the reign of Queen Victoria, the Orange is now very much affordable and available and one of the most popular and most used fruits in the world.

Not only providing excellent levels of Vitamin C, but also dietary Fibre, Folate, energy producing Vitamin B1 and Calcium amongst other Vitamins and minerals, Oranges also contain more than 60 Flavonoids that provide a powerful anti-inflammatory/antioxidant effect by interacting with Vitamin C and hopefully providing protection against oxidative damage to cell structures, including DNA.

Foods or Supplements.Can they both be effective?

What previous studies have shown prior to BYU's work has suggested that Vitamin C are more readily absorbed when consumed together with other biological active Flavonoids or Phytonutrients contained in citrus fruits than when taken singly as maybe the case with supplement form.
BYU research wanted to look at the large combinations of antioxidants found in the orange at the same proportions they occur naturally with significant results-

"Cases where the effect of two or more antioxidants together was stronger than the sum of them separately."

 
Identifying combinations of antioxidants found not only in Oranges, but also in Blueberries and Strawberries the University team were able to identify specific compounds within the fruit, for instance in Oranges, hesperidin which has been shown to lower high blood pressure as well as Cholesterol in animal studies, and naringenin that together when working with Vitamin C provide the greatest antioxidant punch and hence potential benefit to health.


Whilst the best antioxidant mixtures are further studied and developed by commited teams such as those led by head author Brenner Freeman and Tory Parker at BYU, one thing is for sure, as l point out to my patients and will always hopefully portray in these articles, eating the healthy, hopefully Organic (or well washed) fruit will be more beneficial to the majority than the parts that make up the supplement!

And though l don't calorie count...at just 62 Calories, what better food as part of a well balanced diet could there be!


Find fruits your enjoy-make up a fruit salad on the weekends for the days ahead!
