How Does PCOS Affect Fertility?

Polycystic Ovary Syndrome (PCOS) is a common hormonal disorder among women of reproductive age, affecting about 5-10% of the female population. It is characterised by irregular menstrual cycles, excess androgen levels, and cysts on the ovaries. It not only impacts a woman’s overall health but can also have significant implications for fertility.

Causes of PCOS

It is believed to be complex, with genetic, environmental, and lifestyle factors playing roles. Genetic predisposition, insulin resistance, and hormonal imbalances are key factors contributing to the development of PCOS.

Symptoms of PCOS

The symptoms can vary from person to person but commonly include irregular menstrual cycles, excessive hair growth, acne, and weight gain. Other symptoms may include hair loss, darkening of the skin, and mood changes.

Diagnosis of PCOS

Diagnosis involves a combination of medical history review, physical examination, blood tests to measure hormone levels, and ultrasound imaging to assess the ovaries for cysts.

Understanding Infertility

Infertility is defined as the inability to conceive after one year of regular unprotected intercourse. Various factors can contribute to infertility, including hormonal imbalances, structural issues, and lifestyle factors. Ovulation, the release of an egg from the ovary, is essential for fertility, as it is the process through which pregnancy occurs.

Link Between PCOS and Infertility

It is closely linked to infertility due to its effects on ovulation. Hormonal imbalances, such as elevated levels of insulin and androgens, can disrupt the normal ovulation process. Anovulation, the absence of ovulation, is common in women with PCOS, leading to irregular or absent menstrual periods and difficulty conceiving.

Effects of PCOS on Reproductive Health

It can have several effects on reproductive health that contribute to infertility. Menstrual irregularities, such as oligomenorrhea (infrequent periods) or amenorrhea (absence of periods), are common in women with PCOS. Ovarian cysts, which are fluid-filled sacs on the ovaries, can also interfere with ovulation. Additionally, insulin resistance, a sign of PCOS, can affect fertility by disrupting hormone levels and damaging egg development.

Management and Treatment Options

Managing PCOS is important for improving fertility outcomes. Lifestyle changes, including regular exercise, a balanced diet, and weight management, can help regulate hormone levels and promote ovulation. Medications such as clomiphene citrate or letrozole may be prescribed to induce ovulation in women. In cases where these treatments are unsuccessful, assisted reproductive technologies (ART) such as in vitro fertilization (IVF) may be recommended.

Support and Resources for Women with PCOS

Living with it can be challenging, both physically and emotionally. Fortunately, there are numerous resources available to support women on their fertility journey. Support groups and online communities provide a platform for women to connect with others facing similar challenges and share experiences. Counselling and mental health support can also be beneficial in addressing the emotional aspects of living with PCOS and infertility.

In conclusion, PCOS can have a significant impact on fertility due to its effects on ovulation and reproductive health. However, with proper management and treatment, many women can achieve successful pregnancies. Seeking professional help from healthcare professionals specialising in reproductive medicine is important for women with PCOS who are struggling with infertility.


1. Can women with PCOS get pregnant naturally?

Yes, although women may have difficulty conceiving due to irregular ovulation, many can still get pregnant naturally with proper management and lifestyle changes.

2. Are there any specific dietary recommendations for women with PCOS?

A balanced diet that is low in refined carbohydrates and sugars and high in fibre, protein, and healthy fats is often recommended for women to help manage symptoms and improve fertility.

3. What role does exercise play in managing PCOS-related infertility?

Regular exercise can help improve insulin sensitivity, regulate hormone levels, and promote weight loss, all of which can contribute to improved fertility outcomes in women.

4. Are there any alternative therapies that may help with PCOS-related infertility?

Some women may find acupuncture, herbal supplements, or mindfulness practices beneficial in managing symptoms and improving fertility, although more research is needed to confirm their effectiveness.

5. How long should women with PCOS try to conceive before seeking medical intervention?

Women under 35 who have been trying to conceive for one year without success should consider consulting a healthcare provider specializing in reproductive medicine. For women over 35, it is recommended to seek help after six months of trying unsuccessfully.
