More sports, smoking cessation, healthier eating and homeopathy – even men give everything in their unfulfilled desire to have children to increase fertility.
Causes of poor male fertility
Current estimates suggest that up to 16.7 percent of couples in industrialized countries are affected by infertility.
Up to 50 percent of cases are made up of men who cannot father children. As a rule, fertility problems in men manifest in the form of too little sperm (oligozoospermia) or poorly floating sperm (astenozoospermia).
Another problem that can reduce a man's fertility is seeds of poor size and shape (teratozoospermia).
In rare cases, there may be a combination of all three factors that can now be consumed by the consumption of tomatoes.
What is special about tomatoes?
Lycopene is a carotenoid found in high concentrations in tomatoes, tomato products and other red pigmented foods.
In recent years, there has been a growing emphasis in scientific research as a potential therapist for various health disorders.
Lycopene is also specifically attached to the immune system because it protects against free radicals and thus against cancer. In addition, it should be able to increase male fertility.
The appearance of lycopene in fresh tomatoes is small. However, this is improved by processing and heating the tomatoes with oil – so that the tomato pulp contains more lycopene.
Does lycopene actually increase fertility?
Researchers around Professor Allan Pacey were also aware of the current fertility problem – and began to look for a solution in the nutrition sciences.
For this study, researchers studied 60 healthy men with no known fertility problems between the ages of 19 and 39 over a 12-week period.
The sperm of the subjects were examined for volume, concentration, motility, morphology, DNA damage, and plasma lycopene concentration.
The men were divided into two groups, with one half receiving high-dose lycopene supplementation. The other half were on placebo preparation – both groups were unaware that they were taking lycopene or placebo.
Subjects were given 14 mg of lycopene daily – intake of two kilograms of cooked tomato or two tablespoons of concentrated tomato puree.
Sperm quality can change
The researchers studied the concentration of motile sperm because this variable is related to the likelihood of conception.
In fact, sperm concentration during lycopene administration could not be statistically improved.
However, two other measures of sperm quality have been significantly altered. The proportion of rapidly progressing sperm and the proportion of sperm with normal morphology could be positively increased and improved.
According to the researchers, these are very positive results, but they are still not a new fertility drug.
In order to show results, further broader testing needs to be conducted.
