What is PMOS? The New Name for PCOS
PCOS has been renamed PMOS — Polyendocrine Metabolic Ovarian Syndrome. The new name was adopted to better reflect the true nature of the condition, which extends well beyond the ovaries to affect the endocrine and metabolic systems more broadly.
The condition itself has not changed. The same symptoms, diagnosis criteria and treatment pathways apply. If you have previously been diagnosed with PCOS, that diagnosis remains valid — you may simply see the condition referred to as PMOS going forward.
At Monash IVF, we are transitioning to the PMOS terminology in line with the latest international medical guidance.

Managing and Treating PMOS (PCOS)

How PMOS (PCOS) Affects Fertility and Conception
PMOS (PCOS) is a leading cause of female infertility. As we mentioned above, a woman with the condition may experience irregular periods due to an increase of male-type hormones known as androgens. These hormones can prevent ovulation, which in turn makes it difficult to conceive naturally. Overweight or obese women with PMOS (PCOS) have the most difficulty conceiving - either naturally or with fertility help.
The cheering bit? With the right treatment, 60% of women with PMOS (PCOS) can conceive naturally without any fertility clinic intervention.
