Male infertility is due to low sperm production, misshapen or immobile sperm, or blockages that prevent the delivery of sperm. Over the years, male fertility has decreased worldwide; for example, since the mid-1970s, male sperm density has fallen by 40%. There are causes of male infertility that are known and unknown. Known causes include medical conditions that result in low sperm count or changes in sperm, urogenital infections, immunologic factors (anti-sperm antibodies), sexual/ejaculatory inadequacy, acquired urogenital abnormalities, and endocrine disorders. There also are congenital disorders, such as Kallmann’s and Klinefelter’s syndrome, and others.
Known causes of male infertility tend to have targeted and effective treatment options, but 30-50% of male infertility cases have idiopathic (unknown) causes. In idiopathic infertility, there are unexplained changes in parameters such as low sperm concentration, reduced sperm motility, and abnormal sperm shape. Idiopathic cases of infertility are mostly associated with lifestyle choices—diet, alcohol consumption, weight and smoking—as well as age. To improve fertility after age 35, men should maintain a healthy diet, exercise at least 2-3 times a week, reduce alcohol consumption and smoking, and take the Fruitful for Him fertility supplement.
