  • About 20% of cases of infertility are due to a problem in the man.
  • About 40% to 50% of cases of infertility are due to a problem in the woman.
  • About 30% to 40% of cases of infertility are due to problems in both the man and the woman.
  • Age – a woman’s fertility starts to drop after she is about 32 years old, and continues doing so. A 50-year-old man is usually less fertile than a man in his 20s (male fertility progressively drops after the age of 40).

Risk factors of Infertility –
Smoking – smoking dangerously increases the risk of infertility in both men and women. Smoking may also reduce the effects of fertility treatment. Even if a young woman, who smokes, gets pregnant, she has a big risk of miscarriage.
Alcohol – Pregnancy can be seriously affected by any amount of alcohol consumption. Alcohol abuse may reduce male fertility. Moderate alcohol consumption has not been shown to lower fertility in most men, but is thought to lower fertility in men who already have a low sperm count.
Obese or overweight – People who are overweight/obese and live a sedentary lifestyle are often found to be the alarming causes of female infertility. An overweight man has a higher risk of having abnormal sperm.
Eating disorders – Women who are too underweight as a result of an eating disorder may have fertility problems.
Strictly vegan – If your intake of iron, folic acid, zinc and vitamin B-12 is adequate, your fertility won’t be affected.
Over-exercising – A woman who exercises for more than seven hours a week may have ovulation problems.
Sexually transmitted infections (STIs) – Chlamydia can damage the fallopian tubes, also the man’s scrotum has inflammation. Other STIs may also cause infertility.
Chemical exposure – Some pesticides, herbicides, metals like lead and solvents have been linked to fertility problems in both men and women.
Mental stress – Research confirms that female ovulation and sperm production may be affected by mental stress.
