Most of the risk factors for infertility either male of female are similar. The greatest ones are the following:
Age. In men, after they are 35 years old, the gradual decline in fertility begins as a rule. However, the woman’s fertility potential decreases somewhat earlier, after about the age of 32. Older women may suffer from infertility because of the higher rate of chromosomal abnormalities, occurring in the eggs with age. Health problems, which interfere with fertility, may also be in older women. Moreover, the risk of miscarriage also increases as the time goes by.
Tobacco smoking. Those men and women, who smoke tobacco, reduce their chances to conceive and carry their pregnancy to term successfully. Moreover, their chances to benefit from fertility treatment reduce as well. However, it should also be noted, that women, who smoke face the problem of miscarriage more often than those, who do not.
Alcohol use. There exists no safe level of alcohol usage during the period of conception as well as during pregnancy for women. However, reasonable use of alcohol does not seem to influence males’ fertility.
Obesity. One of the risks of infertility, especially concerning women infertility is leading a sedentary lifestyle and being overweight.
Being underweight. Except women, who are overweight, those women, who do not have sufficient body mass are also at risk of having problems with their ability to conceive. Here also belong women, who suffer from some eating disorders, like anorexia and bulimia; and those women, who follow a low – calorie or restrictive diet. Moreover, if a person is a strict vegetarian (no matter whether it is a man or a woman), he may also be infertile, though temporary, because of the lack of important vitamins and minerals, such as Vitamin B – 12, zinc, iron, folic acid, etc. in his organism.
Too much exercise. According to some recently conducted investigations, if a woman makes physical exercises more than seven hours a week (which makes more than one hour a day), this may be associated with her ovulation problems. Moreover, strenuous exercises may also influence the success of an in vitro fertilization in a negative way. However, if a woman does not do any physical exercises at all, she may be suffering from obesity, and then she will also be at risk of infertility. The best decision is to do everything in a reasonable amount.
Caffeine intake. There is no single opinion in whether consuming too much caffeine may have something to do with the fertility problems. There are investigations, which prove that the increase of caffeine intake decreases fertility, however, others prove there is no adverse effect of caffeine on fertility issues. Therefore, if there are any negative influences of caffeine on fertility, this concerns more women, than men. Still, taking a lot of caffeine may cause miscarriage.
