PCOS in sub-Saharan Africa: review highlights a lack of general population data

Research concentrated in a few countries and focused on infertility

The authors searched for original studies on PCOS in sub-Saharan African populations, with no age restrictions. Their search covered PubMed, Embase, Cochrane and African Journals Online up to August 9, 2026.

Of 1,973 records identified, 40 studies met the inclusion criteria. They came mainly from Nigeria, with contributions from South Africa, Cameroon, the Democratic Republic of the Congo, Tanzania, Benin, Kenya and Ethiopia.

Most were observational and examined PCOS in the context of infertility. This focus leaves other aspects of the syndrome less well documented, including its manifestations and metabolic consequences.

Clinical prevalence figures do not describe the whole population

Thirteen studies reported PCOS prevalence, but they mainly involved selected populations in clinical settings. No general population prevalence study was identified.

This distinction changes how the findings should be interpreted: the frequency observed among people recruited in clinical settings cannot be extrapolated to the entire population. The review therefore cannot establish how many women are affected in the region.

The geographical concentration of the studies also limits their scope. Data drawn mainly from Nigeria are not enough to describe the situation across sub-Saharan Africa.

What this review changes—and what it does not

The authors identify gaps in epidemiology, diagnostic practices, the different presentations of PCOS, its management and metabolic outcomes. They also highlight barriers related to cultural attitudes, cost and access to diagnostic tools and treatments.

These findings help set research priorities, but do not demonstrate the effectiveness of any treatment or nutritional intervention. This review provides a map of missing knowledge, not a new management protocol.

What we can take away

The main finding is a lack of representative data, not an estimate of how common PCOS is in sub-Saharan Africa. The available studies mainly shed light on clinical populations, often in the context of infertility.
