When women hear terms like PCOD or PCOS, it often creates confusion. Many people are told they have one of these conditions but receive very little explanation about what it means for their health, hormones, or fertility.
In many countries, the term PCOD (Polycystic Ovarian Disease) is used in everyday conversation. However, modern medical guidelines do not recognise PCOD as a separate diagnosis. Most doctors use the term PCOS (Polycystic Ovary Syndrome).
Understanding this difference is important. It helps women better understand their symptoms, ask the right questions, and make informed decisions about treatment and fertility planning.
In this guide, we will explain what PCOS is, why the term PCOD is sometimes used, and how this condition can affect ovulation, fertility, and long-term health.
PCOD and PCOS – Are they the same?
Many women ask: Are PCOD and PCOS different conditions?
According to international medical guidelines, PCOS is a recognised medical diagnosis. The term PCOD is often used informally or interchangeably with PCOS, especially in some regions (particularly in South Asia and parts of Europe).
Today, most doctors prefer to use PCOS because it better reflects that the condition can affect more than just the ovaries. It involves the hormones, metabolism, and ovulation patterns of the body.
Instead of being two separate diseases, PCOS is now understood as a spectrum of hormonal patterns. This means different women may experience different symptoms and levels of severity.
Some women may have mild symptoms and ovulate occasionally. Others may have more noticeable hormonal changes and irregular ovulation.
What Is PCOS?
PCOS stands for Polycystic Ovary Syndrome. It is a hormonal condition that affects how the ovaries function and how certain hormones are balanced in the body.
In PCOS, several things may happen:
- Ovulation may occur less often
- Hormone levels may become imbalanced
- Body may produce higher levels of androgens (male-type hormones)
- Ovaries may show many small follicles on ultrasound
These follicles are not dangerous cysts. They are small eggs that started to develop but did not complete the ovulation process.
PCOS can also affect how the body uses insulin, which helps control blood sugar. This is why some women with PCOS develop insulin resistance or weight gain more easily.
Common symptoms of PCOS
PCOS symptoms can vary widely. Not every woman will experience the same signs.
Common symptoms include:
- irregular or missed periods
- ovulation that happens infrequently
- acne or oily skin
- excess facial or body hair
- hair thinning on the scalp
- weight gain or difficulty losing weight
- difficulty getting pregnant
Some women may only have mild symptoms, while others may experience several at the same time.
How doctors diagnose PCOS
PCOS is usually diagnosed using the Rotterdam Criteria, which is recommended by international guidelines.
A diagnosis is made when two out of three of the following are present:
- Irregular or absent ovulation
- Higher androgen levels (seen in blood tests or symptoms such as excess hair growth or acne)
- Polycystic ovarian appearance on ultrasound
Because PCOS can look different in each person, doctors often combine medical history, blood tests, and ultrasound results to confirm the diagnosis.
How PCOS affects ovulation and fertility
Many women first learn about PCOS when they are trying to conceive. With PCOS, ovulation may happen less often or at unpredictable times. This can make it harder to know when the fertile window occurs.
However, an important thing to know is that many women with PCOS still ovulate and can conceive naturally. In long term studies, it was found that a significant number of women with PCOS became pregnant naturally over time, especially when ovulation patterns were identified and supported.
Healthy lifestyle habits, medical guidance, and proper cycle tracking can greatly improve fertility outcomes.
Tracking ovulation with PCOS
Tracking ovulation can help women better understand their cycle patterns. Many people use ovulation predictor kits (OPKs) that detect luteinising hormone (LH). A rise in LH usually signals that ovulation may occur soon.
However, women with PCOS sometimes have chronically elevated LH levels, which can make LH tests harder to interpret. This does not mean LH tests cannot be useful. It simply means they often work best when combined with other tracking methods.
Other tracking methods include:
- Basal Body Temperature (BBT): A resting body temperature that stays higher than usual for at least three days may suggest that ovulation has occurred. This shift typically shows a temperature increase of 0.5°C to 1.0°C compared to the six days before the suspected egg release.
- Progesterone (PdG) Rise: Using at-home test urine strips to measure PdG (a marker of progesterone) may help determine if ovulation was likely successful. These strips look for the urine PdG level to reach or exceed 5 μg/mL for three consecutive days during the “implantation window,” which is roughly 7 to 10 days after your LH peak.
Tracking patterns over several cycles is helpful for women with PCOS. Instead of relying on one single test result, observing hormone trends over time can provide clearer insight. Tools like thePremom app allow users to track LH patterns, monitor BBT shifts, and better understand irregular cycles.
Can women with PCOS get pregnant?
Yes, many women with PCOS do become pregnant. While ovulation may not occur every cycle, it still happens occasionally. With proper timing, many couples may conceive naturally.
In some cases, doctors may recommend treatments to regulate ovulation. These can include lifestyle changes, medications, or fertility support when needed.
You must understand that PCOS does not mean pregnancy is impossible. It simply means the body may need a more personalised approach.
Long-term health considerations
PCOS can affect more than fertility. As it influences hormones and metabolism, it may also increase the risk of certain health conditions later in life.
These may include:
- Type 2 diabetes
- high blood pressure
- heart disease
- pregnancy complications such as gestational diabetes
The good news is that early awareness and lifestyle care can greatly reduce these risks. Regular exercise, balanced nutrition, and medical monitoring can help support long-term health.
Frequently asked questions (FAQs) – PCOD vs PCOS: Why the difference matters
No. Modern medical guidelines recognise PCOS as the formal diagnosis. The term PCOD is often used informally, but usually refers to the same condition.
Early signs may include irregular periods, acne, unwanted hair growth, or difficulty ovulating.
Hormonal imbalance and inflammation in PCOS may affect how eggs mature. However, many women with PCOS still produce healthy eggs and achieve successful pregnancies.
PCOS is considered a long-term condition. While it cannot be permanently cured, symptoms can be effectively managed with lifestyle care and medical support.
Start understanding your cycle
If you are unsure about your symptoms or worried about ovulation, learning about your own cycle is a powerful first step.
Tracking ovulation using LH tests, confirming ovulation with basal body temperature, and observing hormone patterns over time can provide valuable insights.
Apps like Premom allow you to monitor LH trends, track BBT changes, and understand irregular cycles more clearly.
If you need personalised guidance, you can also connect with fertility experts through the Ask an Expert section inside the Premom app.
You are not alone on this journey. With the right information and support, many women successfully manage PCOS and achieve their fertility goals.
