Poly Cystic Ovarian Syndrome (PCOS) is a common endocrine disorder among women of reproductive age. Women suffering from PCOS present a group of symptoms associated with menstrual irregularities and androgen(male hormone) excess, which signiﬁcantly impacts their quality of life. They may be at increased risk of multiple complications, including obesity, insulin resistance, type 2 diabetes, heart disease, infertility, cancer, and psychological disorders. (El Hayek et al., 2016)
The economic burden of PCOS is signiﬁcantly huge. Around 4 billion dollars are spent annually in the United States to screen for the disease and treat its various morbidities, including hirsutism, infertility, and diabetes mellitus (Azziz et al. 2005)
Most women with PCOS grow many small cysts on their ovaries. That is why it is called polycystic ovary syndrome. The cysts are not harmful but lead to hormone imbalances.
Accurate and early diagnosis of PCOS is necessary not only to prevent future health problems but also to reduce ﬁnancial cost and burden.
Myo-inositol (MI) and D-chiro-inositol (DCI), two inositol stereoisomers, have been proven to be effective in PCOS treatment. However, only MI has been shown to have beneficial effects on reproductive function, whereas the administration of MI/DCI, in the physiological plasma ratio (i.e., 40:1) ensures better clinical results, such as the reduction of insulin resistance, androgens’ blood levels, cardiovascular risk and regularization of menstrual cycle with spontaneous ovulation.
