A recent article published last week in the journal Hormone molecular biology and clinical investigation showed how myo-inositol in addition to folic acid can improve symptoms and infertility in patients with polycystic ovary syndrome (PCOS).
Polycystic ovary syndrome (PCOS) is a complex endocrine disorder with implications for reproductive and metabolic health. It is a very common endocrine condition affecting approximately 5 million of women in the United States (1) and characterized by:
Higher % of high quality embryos in the treated group
It is important to note that rFSH during stimulation was administrated for a significantly shorter time and at a lower dose in the treated group which significantly decreases the risk of hyperstimulation.
In Endometriosis, similarly to PCOS patients, the lipid (2) and glucose (3) metabolisms are disrupted which can favor oxidative stress (through lipid peroxidation).
As in PCOS, oxidative damage is a key component of poor egg quality, parameter commonly found in endometriosis patients (4), thus leading to poor fertilization and implantation rate (5).
Myo-inositol is a well-documented and powerful antioxidant (reducing oxidative stress and its associated oocyte damage) that decreases hyperandrogenism and insulin resistance (6-7).Through its effects on the calcium pathway, myo-inositol plays a direct and key role on the maturation of an oocyte (egg) which leads to better oocyte quality and increased ovulation rate (8-10). Further this has an impact on fertilization and early embryo development (11). Thus, myo-inositol significantly increases fertilization and pregnancy success rate as previously reported (12-13).
Myo-inositol could be safely used as an agent to help restore better oocyte quality leading to better embryo quality and higher chances of getting pregnant, especially in PCOS and Endometriosis patients.
Myo-inositol is one of the several ingredients of our Endo-Optimize supplement.
This formulation has been developed to be the best solution to counteract oxidative stress induced-DNA damage and optimize your egg quality as well as minimizing your symptoms associated with endometriosis and PCOS.
This all in one pill contains many ingredients enhancing mitochondrial activity (a key component in oocyte development) and reducing inflammation thus allowing optimal microenvironment for the oocyte development and maturation. To learn more about the topic, read our blogENDO-optimize: an "all in one" dietary supplement with beneficial effects on egg quality, endometriosis and PCOS.
