Infertile women had statistically significant higher body mass index (BMI), increased total cholesterol (TC), low\u2010density lipoprotein cholesterol (LDL\u2010C) and triglycerides (TG) compared with fertile women. Fasting glucose, fasting insulin, homeostatic model assessment of insulin resistance (HOMA\u2010IR) and mean arterial pressure were not found to be different between fertile and infertile women. A subgroup analysis revealed that TC, fasting glucose and fasting insulin were increased, and high\u2010density lipoprotein was decreased only in women with polycystic ovarian syndrome compared with fertile women, whereas BMI, TG and LDL\u2010C were statistically significantly increased in women with any indication of infertility compared with fertile women.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>Infertile women have a higher level of cardio\u2010metabolic risk factors compared with fertile women.
