Polycystic ovary syndrome (PCOS), now also officially known as polyendocrine metabolic ovarian syndrome (PMOS), is described here using the familiar term PCOS.

PCOS can affect fertility mainly by making ovulation irregular. Importantly, many people with PCOS conceive, some naturally, others with support.

This page explains the connection and the options that exist.

How PCOS can affect fertility

Because PCOS can make ovulation irregular or infrequent, it can take longer to conceive. This varies a lot between individuals.

Options that may help

Where ovulation is irregular, options to support it may be discussed, alongside general health measures. These are considered individually with a specialist and framed as options, not guarantees.

When to see a specialist

If you have PCOS and are planning a pregnancy or finding it hard to conceive, it's reasonable to seek advice, earlier if you're over 35.
