Hey there! If you’ve been struggling with irregular ovulation, you might be dealing with a common endocrine issue that affects many women of reproductive age. While polycystic ovary syndrome (PCOS) is often the first thing that comes to mind, there’s another condition that can mimic its symptoms: Late-Onset Congenital Adrenal Hyperplasia (CAH).
PCOS affects about 6-8% of women in the general population, leading to symptoms like abnormal bleeding and signs of excess male hormones—think facial hair or acne. But here’s the kicker: Late-Onset CAH can present in women with a very similar symptom profile, including infrequent ovulation and elevated androgen levels. This overlap can lead to misdiagnosis, meaning that some women may not receive the appropriate care they need.
Interestingly, mutations in the 21-hydroxylase enzyme are more common than you might think—affecting anywhere from 1 in 1000 to 1 in 100 Caucasians, with even higher rates in certain ethnic groups. For example, in parts of Turkey, the prevalence among women with PCOS-like symptoms can reach an astonishing 60%.
So, why does this matter? Well, while treatments for PCOS and Late-Onset CAH often overlap (hormonal birth control is a common first-line therapy), the stakes get higher for women wanting to conceive. If a woman with late-onset CAH has a partner who’s also a carrier of a severe mutation, there’s a risk of their child inheriting two different mutations that could lead to the classic—and potentially lethal—form of CAH at birth. This makes preconception genetic testing and counseling crucial.
A simple blood test can distinguish between late-onset CAH and PCOS, making all the difference for those trying to start a family. For more insights on fertility treatments, don’t miss this post about frozen embryo transfers.

In summary, while PCOS is a common diagnosis, it’s essential to consider other conditions like late-onset CAH that can present similarly. Getting the right diagnosis can not only help in managing symptoms but also in making informed decisions about family planning.
