简要总结
The polycystic ovarian syndrome (PCOS) is a common gynaecological condition that affects women in the reproductive age group. Currently, between 15-20 million couples are affected in India, and PCOS is a common cause of infertility. Apart from infertility, PCOS is associated with long term complications such as cardiovascular diseases, diabetes mellitus as well as endometrial cancer. Commonly, apart from lifestyle intervention, Metformin therapy along with ovulation induction with Letrozole is considered as first-line pharmacological intervention. However, in contemporary practice, Myo inositol has also been used as an alternative to Metformin although the supportive evidence for Myo inositol is weak. Furthermore, there is scare data from the South Asian region. The current trial has been planned to study the effectiveness of Myo inositol in women with PCOS who wish to conceive and compare it against the Metformin as well as placebo.
The main objective of the study is to assess whether fertility-related outcomes improve following Myoinositol compared to Metformin and placebo in women with PCOS who wish to concieve. The secondary objectives include assessing whether there is improvement in endocrinological & metabolic parameters as well as obstetrics outcomes following Myoinositol versus Metformin & placebo. Finally, we also want to asses if there are any epigenetic changes pre and post-intervention.
The study is a multicentre placebo controlled randomized study involving women with PCOS who wish to conceive. The study results will inform us on whether use of Myoinositol is beneficial for women with PCOS who wish to conceive and fill in the knowledge gap in the area. It
