Menstrual preconditioning for the prevention of pregnancy complications in women with polycystic ovary syndrome (PCOS): Clinical opinion or viewpoint - This is the question

We have read with great interest the Clinical Opinion recently published on menstrual preconditioning for the prevention of pregnancy complications in women with polycystic ovary syndrome (PCOS).1 This paper provides a very interesting and provocative view on the potential role of menstrual shedding on the genesis of the increased incidence of the obstetric and/or neonatal complications observed in women with PCOS.2 Moreover, it seems to be more of a personal viewpoint than a clinical opinion because many statements/topics are not adequately balanced, especially for a reader without sufficient experience in the field.
