A number of findings have related dietary habits to fertility in men and women. And they include:
- Excessive carbohydrates intake by men reduce the sperm quality
- Reduced carbohydrate intake and excessive protein intake enhanced chances of pregnancy.
Both these findings have showed a concrete link between dietary habits and fertility and this suggestion has augmented by the studies that was conducted by J. B. Russell endocrinologist and infertility expert at Christiana Care Health Systems in Newark, Del. A pair of studies on which this research was based was conducted by an associate professor of epidemiology and nutrition, Dr. Jorge Chavarro and research associate Myriam Afeiche both of whom were attached to the Harvard School of Public Health. The team led two investigations to assess the reason for the decline of sperm quality of which one focused on the excessive intake of carbs while the other focused on the excessive intake of dairy products.
According to Chavarro, there is a declining trend in sperm count in the whole of the 20th century and continued to the early parts of the 21st century though there is no clear indication as to the reason for this decline. Some of the factors responsible are hypothecated to be environmental factors and obesity.
The results showed that intake of carb did not impact the mobility or the shape of the sperm but it did have an impact on the sperm count. On the other hand, in the case of excessive diary intake, the mobility of the sperm was not affected as also the sperm count. But it showed some changes in the shape of the sperm as the intake dairy products increased. Though there were other determining factors like alcohol consumption, smoking history, intake of caffeine and body weight the results of the tests remained unaffected.
In the case of women with no IVF history and whose dietary habits included high proteins diets and low carb diets were more likely to get pregnant. But in women who had an IVF history and yet failed to conceive underwent analysis of food intake and were also given counseling. It was found that after analysis and counseling on repeated IVF the success rate of pregnancy jumped from 19% of women who got pregnant in the first IVF attempt to almost 45% of women who underwent food counseling.
Hence it can be concluded that nutrition does play an important role in the quality of sperm in men and fertility in women.
