PCOS Awareness Month

About

PCOS Awareness Month is observed throughout September to raise understanding of polycystic ovary syndrome (PCOS), a common hormonal and metabolic condition that can affect people in different ways. The observance helps bring attention to symptoms such as irregular periods, acne, excess hair growth, and fertility challenges, while recognizing that experiences vary widely and may change over time.

Throughout the month, communities, healthcare professionals, and advocates encourage open conversations about diagnosis, treatment, mental health, and long-term well-being. PCOS Awareness Month also reminds those living with PCOS that they are not alone and promotes compassionate, informed support for everyone affected by the condition.

History

PCOS Awareness Month is observed throughout September to raise understanding of polycystic ovary syndrome (PCOS), a common hormonal and metabolic condition affecting people of reproductive age. PCOS may involve irregular or absent ovulation, elevated androgen levels, and polycystic-appearing ovaries, although not everyone experiences the same combination of symptoms. The condition was first described medically in 1935 by Irving Stein and Michael Leventhal, whose work gave rise to the earlier term “Stein-Leventhal syndrome.” Over time, medical research has shown that PCOS is more complex and varied than that original description suggested.

The modern awareness observance developed from sustained advocacy by patients, clinicians, researchers, and organizations working to improve recognition of PCOS. PCOS Challenge, a U.S.-based nonprofit organization, helped establish PCOS Awareness Month in 2018, giving advocacy efforts a recurring period for public education and outreach. Its goals include encouraging earlier diagnosis, improving access to appropriate care, and drawing attention to the reproductive, metabolic, and emotional effects associated with the condition. September observances commonly include educational campaigns, online discussions, fundraising initiatives, and opportunities for people with PCOS to share their experiences.

The significance of the month has expanded as understanding of PCOS has evolved. Earlier public discussions often concentrated primarily on fertility or visible symptoms such as excess hair growth and acne. Awareness efforts now emphasize that PCOS can also be connected with insulin resistance, type 2 diabetes, cardiovascular risk factors, sleep difficulties, anxiety, depression, and other long-term health concerns. At the same time, advocates stress that PCOS is not defined by infertility or by a particular body type, and that symptoms and health needs differ widely from person to person.

Culturally, PCOS Awareness Month has helped bring greater visibility to a condition that is frequently underdiagnosed, misunderstood, or diagnosed only after years of symptoms. It creates space for more accurate conversations about menstruation, hormonal health, fertility, weight stigma, mental health, and the need for individualized treatment. By combining medical information with patient advocacy, the September observance encourages people to seek professional guidance while promoting broader recognition of PCOS as a significant and multifaceted health issue.

Timeline

1935
Irving F. Stein Sr. and Michael L. Leventhal published their description of seven women with amenorrhea, hirsutism, enlarged polycystic ovaries, and infertility, a landmark account of what became known as polycystic ovary syndrome (PCOS).
1990
A National Institutes of Health conference established influential diagnostic criteria for PCOS, centered on chronic anovulation and clinical or biochemical hyperandrogenism after exclusion of other causes.
2003
The Rotterdam consensus workshop of the European Society of Human Reproduction and Embryology and the American Society for Reproductive Medicine introduced the widely used Rotterdam diagnostic criteria, requiring two of three features: ovulatory dysfunction, hyperandrogenism, and polycystic ovarian morphology.
