Inadequate intake of zinc rich foods like meat, shell fish, liver gelatin, beans, rice, bread, cereals lentils etc.
Incomplete absorption of zinc from the food due to many barrier likes presence of phytic acid in the diet hampers.
- Reduced appetite
- Retarded growth.
Infertility is one of the most serious social problems facing advanced nations. In general, approximate half of all cases of infertility are caused by factors related to the male partner. To date, various treatments have been developed for male infertility and are steadily producing results. However, there is no effective treatment for patients with nonobstructive azoospermia, in which there is an absence of mature sperm in the testes. Although evidence suggests that many patients with male infertility have a genetic predisposition to the condition, the cause has not been elucidated in the vast majority of cases. This paper discusses the environmental factors considered likely to be involved in male infertility and the genes that have been clearly shown to be involved in male infertility in humans, including our recent finding.
Sperm, which holds the male DNA, must be able to move back and forth and propel itself to penetrate the female egg. Fertile males have healthy sperm that swim well, but males with impaired fertility may have a lower sperm count, or sperm that do not swim as well. Zinc may play a role in the development and overall quality and quantity of sperm.
Zinc has antioxidative properties and plays an important role in scavenging reactive oxygen species. We hypothesized that in the absence of Zn, the possibility of increased oxidative damage exists that would contribute to poor sperm quality. Therefore, measurement of seminal Zn in the seminal plasma of males with a history of subfertility or idiopathic infertility is necessary and can be helpful in fertility assessment.
The mineral zinc is naturally present in certain foods, and it is added to other foods. The National Institutes of Health notes that zinc is involved in immune function, wound healing, protein synthesis, DNA synthesis and cell division. Zinc is the second most common trace mineral in the body, behind iron, and is present in every cell in the body. Males 14 years and up need 11 milligrams of zinc per day -- an amount easily obtained through a healthy diet plus a multivitamin.
Zinc may play an important role in the development of sperm, also known as spermatogenesis. A 2009 a study published on the Proceedings of the National Academy of Sciences website found that the concentration of zinc in the testes increases during spermatogenesis. The study also found that zinc deficiencies reduced sperm motility. The study concluded that zinc is a vital mineral in the development of sperm and the regulation of sperm motility. Still, the extent of zinc's role in spermatogenesis is not fully understood.
Deficiencies and Infertility
A 2009 study published in "Nutrition Research" hypothesized that due to zinc's important antioxidant role, a deficiency would increase oxidative damage and promote lower quality sperm. The study found that seminal zinc, in both fertile and infertile males, correlated significant with sperm count. The conclusion was that zinc deficiency is, in fact, a risk factor for low sperm quality and male infertility, for which there is no other apparent cause.
Zinc Plus Folate
A 2002 study published in "Fertility and Sterility" tested the effects of zinc plus the vitamin folate on fertility-impaired males. The study found that while zinc and folate, each on their own, did not improve sperm count, when combined, the two supplements significantly improved sperm count, as well as the percentage of healthy sperm, in fertility-impaired males. Another study published in the "International Journal of Andrology" also found benefits in combining zinc and folate on fertility-impaired males.
In conclusion zinc is an important element required for healthy sperms and male fertility.
Consume two to three servings of these zinc foods daily to support optimal zinc levels.
1. Lamb: 3 ounces: 6.7 milligrams (45 percent dv)
2. Pumpkin seeds: 1 cup: 6.6 milligrams (44 percent dv)
Pumpkin seeds and pumpkin seed oil are able to reduce the risk of breast cancer in post-menopausal women, according to research published in nutrition and cancer. (2) pumpkin seeds are also good for prostate health, and they promote your mental health.
3. Grass-fed beef: 100 grams: 4.5 milligrams (30 percent dv)
Grass-fed beef nutrition includes omega-3 fatty acids and conjugated linoleic acid, a powerful polyunsaturated fatty acid that has been shown to help fight cancer, reduce the risk of heart disease, improve blood sugar, discourage weight gain and build muscle.
4. Chickpeas (garbanzo beans): 1 cup: 2.5 milligras (17 percent dv)
Chickpeas, like all legumes, are a form of complex carbohydrates that the body is able to slowly digest and use for energy. Chickpeas increase satiety and help with weight loss. (4) they also improve digestion by quickly moving foods through the digestive tract.
5. Cocoa powder: 1 ounce: 1.9 milligrams (13 percent dv)
Cocoa powder is a good source of two flavonoids, epicatechin and catechin, which function as antioxidants that help prevent inflammation and disease. Because of the presence of flavonoids in cocoa powder, it helps improve blood flow and lower blood pressure too.
6. Cashews: 1 ounce: 1.6 milligrams (11 percent dv)
Cashews are rich in unsaturated fatty acids and high in protein. Cashews nutrition helps fight heart disease, reduce inflammation, promote bone health and support healthy brain function. Plus, these nuts help with weight loss or maintenance because they make you feel fuller and curb food cravings.
7. Kefir or yogurt: 1 cup: 1.4 milligrams (10 percent dv) (values vary)
Kefir and yogurt are cultured dairy products that serve as probiotic foods. Both kefir and probiotic yogurt support healthy digestion, boost the immune system, promote cardiovascular health and regulate your mood.
8. Mushrooms: 1 cup: 1.4 milligrams (9 percent dv)
Proven mushroom nutrition benefits include the ability to boost immunity due to its antioxidant activities, reduce inflammation, fight cancer, protect your heart and improve brain function.
9. Spinach: 1 cup: 1.4 milligrams (9 percent dv)
Spinach is one of the most nutrient-dense foods in existence. It contains special protective carotenoids that have been linked with decreasing the risk of many diseases, including heart disease, obesity, diabetes, neurodegenerative diseases and even cancer.
10. Chicken: 100 grams: 1 milligram (7 percent dv)
In addition to the zinc present in chicken, it’s also a good source of b vitamins, including vitamin b12, niacin, vitamin b6 and pantothenic acid. The vitamin b12 in chicken helps maintain energy levels, boost mood, maintain heart health and boost skin health.
ZINC AND IT'S IMPORTANCE FOR HEALTH
Zinc is an trace mineral
It is needed for immunity system proper functioning and plays role in cell division, cell growth, hormone production, wound healing and carbohydrates breakdown. Besides this it is needed for senses of smell and taste and enhances the action of insulin
For growth and development during pregnancy, infancy and childhood zinc is required.
It may reduce the risk of common cold if taken regularly for 5 month( Recent study)
Animal protein e.g. Beef, pork and Lamb other good sources are nuts, grains, legumes and yeast. Fruits and vegetables are not good source of zinc.
It is a supplement of multivitamins in the form of Zinc gluconate, Zinc sulphate or Zinc acetate.
