Inositol for Fertility Support

Research suggests that myo-inositol may offer benefits for fertility-related outcomes, particularly in women with polycystic ovary syndrome (PCOS), though the direct evidence from the linked sources is limited to a single registered clinical trial protocol rather than completed study results. The MYPP trial, a multicenter double-blind randomized controlled trial currently underway, was designed specifically to test whether myo-inositol supplementation during pregnancy can reduce complications such as gestational diabetes and preterm birth in women with PCOS — a population that earlier trials and post-hoc analyses suggested may benefit most from this intervention. It is worth noting that the majority of studies provided in this source set are unrelated to inositol or human fertility, covering topics ranging from plant biology to mosquito reproduction to COVID-19 gene expression, and therefore cannot contribute meaningfully to conclusions about inositol's role in human reproductive health. Until the MYPP trial and similar well-designed studies report completed findings, the evidence base for inositol as a fertility support specifically in PCOS populations remains promising but preliminary.
