PCOS becomes PMOS: what does the new name mean?

The new name is more than just a different abbreviation. Many people with PCOS have felt for years that their symptoms were not properly understood or not taken seriously enough. As if it was mainly about "something to do with cysts", while the impact is often much greater.

With the name PMOS, experts want to show more clearly what the condition is really about: a complex hormonal and metabolic condition that deserves attention. Not only around pregnancy or fertility, but throughout life.

Why is the name PCOS changing to PMOS?

The old name PCOS stands for polycystic ovary syndrome. As a result, the emphasis was mainly on cysts on the ovaries. This caused confusion, because PCOS usually does not involve actual cysts.

The name PMOS is therefore a better fit. The new name puts the emphasis on hormones and metabolism, in which the ovaries can also play a role. This broader picture is important, because PMOS can affect various processes in the body, such as the menstrual cycle, ovulation, skin, hair growth, energy and insulin sensitivity. Reduced insulin sensitivity can lead to weight gain and being overweight, which is often difficult to treat.

For many people, this recognition matters. PMOS makes it clearer that this is not a minor or isolated problem, but a condition that deserves good explanation, support and care.

What does PMOS mean for you?

Have you previously been diagnosed with PCOS? Then nothing suddenly changes in your body or your treatment. The condition stays the same. Only the name is different.

For the time being, the names PCOS and PMOS will probably be used side by side. So your doctor, online information or people around you may still use the name PCOS.

What we hope will change is the way the condition is viewed: less as "something to do with cysts" and more as a hormonal and metabolic condition that needs to be taken seriously.

PMOS and getting pregnant

At Nij Clinics, we often see PMOS in relation to a wish to have a child. That makes sense, because PMOS can cause ovulation to be less regular or not to happen at all. This can make it more difficult to get pregnant.

That can be upsetting and frustrating, especially if you have been trying to get pregnant for a while. Fortunately, PMOS does not mean that getting pregnant is impossible. There are various ways to gain more insight into your cycle and, if necessary, to support ovulation.

At Nij Clinics, we look at your cycle, hormones and personal situation. Together, we discuss which step is right for you.

When should you seek help?

Do you have an irregular cycle, do your periods often not come, or are you not getting pregnant? Symptoms such as acne, excessive hair growth or problems with your metabolism can also play a role. In that case, it is wise to have this investigated.

Perhaps you have been living with symptoms for a long time, or have felt in the past that you were not really heard. Know that your symptoms deserve to be taken seriously, even if you do not yet have a clear diagnosis. The first step is to see your GP. Your GP can look into it with you and, if necessary, give you a referral for further tests or treatment.
