In women who suffer from infertility, their difficulty in conceiving is sometimes a sign of underlying health issues. For instance, it will know that women who suffer from infertility have a higher rate of pregnancy complications, even if they conceived without treatment. One of the most common causes for infertility, polycystic ovarian syndrome (PCOS) is often associated with underlying metabolic problems and women with PCOS are more likely to develop medical problems such as diabetes, high blood pressure and heart disease. However, what is less clear whether this is also true in men. A recently published study suggest that men with fertility issues and sperm abnormalities may be more likely to have other seemingly unrelated medical problems.
