It is generally believed that women’s fertility will gradually decrease as they age or by factors such as work or emotional stress. Their partners may not have control over all the causes that affect fertility, but at least they can start by adjusting their diet. According to Harvard Medical School nutrition studies related to fertility, in addition to medical infertility treatment interventions, nutrient intake and healthy weight is also a key factor in fertility.

5 Causes of Infertility


Excessive weight is harmful to hormonal secretion and makes women less susceptible to pregnancy. According to the Director of Obstetrics and Gynecology Dr.  William Schlaff from the  Philadelphia University and Thomas Jefferson University Medical School “The heavier women weigh, the worse their ovarian function”.

Chemical pollution

According to a study published in 2013 in Environmental Health Perspectives , high exposure to pollutants, industrial chemicals and pesticides can reduce fertility by up to 29%.


According to a published Journal Environmental Health Perspective in 2013, smoking can increase the chance of infertility by 13% because smoking can harm developing embryos, interfere with hormones, and destroy DNA in the human body.


Exercise is good for health, but overexercising is harmful to female fertility. Dr. William Schlaff also noted that oversports affects women’s ovulation. In 2012, an article published in the Fertility and Sterility has found that women with normal weight who exercise more than 5 hours a week are more difficult to conceive.

Infertility Diseases

The Obstetrician & Gynecologist, the 2015 journal of Obstetrician & Gynecologist, says that thyroid disease can cause ovulation and conception problems. In addition, other reproductive related diseases such as polycystic ovary syndrome, Endometriosis, Uterine fibroids, etc., can cause infertility or miscarriage.
