pcos and egg quality

Polycystic ovary syndrome (PCOS) is a condition that affects a woman’s hormone levels caused by an imbalance of reproductive hormones.

According to CDC (centers for disease control and prevention), PCOS is the common cause of female fertility affecting around 6%-12% of US women of reproductive age.

One of the key challenges associated with fertility is the impact PCOS has on egg quality. 

The quality of eggs produced by a woman’s ovaries plays a crucial role in fertility.

Understanding the relationship between PCOS and egg quality is vital for individuals facing difficulties conceiving. 

In this article, we delve into the intricate connection between PCOS and egg quality, shedding light on the factors that affect it and exploring potential solutions.

Understanding egg quality

Egg quality refers to the health and genetic integrity of the eggs produced by a woman’s ovaries. 

The higher the egg quality, the higher the chances of successful fertilization and a healthy pregnancy. 

Conversely, compromised egg quality can result in difficulties with conception, early pregnancy loss, or an increased risk of chromosomal abnormalities in the offspring.

The influence of PCOS on egg quality

PCOS is characterized by hormonal imbalances, specifically elevated Androgens (male hormones) and Insulin resistance. 

These hormonal irregularities affect the normal development and maturation of ovarian follicles, where eggs reside. 

Consequently, PCOS can lead to poor egg quality due to various factors:

Hormonal imbalances

The main characteristic of PCOS is the presence of elevated levels of androgens, including testosterone, in the body.

These high Androgen levels can disrupt the delicate hormonal balance necessary for normal follicle development and ovulation and compromise egg quality.


One of the hallmark characteristics of PCOS is anovulation, which refers to the absence or irregularity of ovulation. 

Normally, a follicle develops and releases a mature egg for fertilization during each menstrual cycle. 

However, in women with PCOS, ovulation may not occur regularly. 

This irregular or absent ovulation prevents the eggs from developing and maturing properly, resulting in compromised egg quality.

Follicle abnormalities

In PCOS, the ovaries often contain multiple small cysts, which contain immature eggs known as follicles. 

These cysts result from follicles that have started to develop but have not matured or ovulated. 

The presence of these cysts can hinder the growth and development of healthy follicles, further impacting egg quality.

Insulin resistance

Insulin resistance is another characteristic feature of PCOS. 

It refers to a condition in which the body’s cells become less responsive to the hormone insulin, leading to higher insulin levels in the blood. 

Insulin resistance can disrupt the delicate hormonal signaling required for normal follicle development and ovulation, affecting egg quality.

Improving egg quality in PCOS

There are measures women with PCOS can take to enhance their egg quality and increase their chances of getting pregnant. 

Some of these measures are,

Make an appointment with your OB-GYN or fertility specialist to develop a personalized strategy based on your age, health status, and PCOS management. 

They can guide you through the treatment options available to improve egg quality.

Consider Coenzyme Q10 (CoQ10) supplements

CoQ10 is an antioxidant that is important in cell energy production. 

CoQ10 supplementation can enhance egg quality and ovarian health. 

Consult your doctor to determine if CoQ10 supplements suit you.

After considering any potential interactions with other medications and your medical history, they will only recommend it to you.

CoQ10 supplements are commonly used to support heart health and alleviate symptoms of certain conditions, such as migraines and statin-induced muscle pain. While the body naturally produces CoQ10, its levels may decrease with age or due to certain health conditions, making supplementation beneficial for some individuals.

Explore L-carnitine and Clomiphene combination

L-carnitine, an antioxidant, when combined with Clomiphene, a medication commonly used to induce ovulation, can improve ovulation quality and increase the chances of conception. 

Discuss this option with your doctor, ensuring they know of any medications or supplements you take.

N-acetyl-cysteine (NAC) supplementation

NAC is an antioxidant that has shown promise in improving ovulation and pregnancy rates in women with PCOS. 

It may aid in successful conception for some women. 

However, it is important to note that the current evidence supporting the use of NAC in PCOS is still limited, and more research is needed. 

While initial findings are encouraging, there is a further need for systematic clinical trials to establish the efficacy and safety of NAC supplementation specifically for PCOS.

Consult your doctor before starting NAC supplements, as it is essential to ensure safety and discuss potential interactions with other medications.


Dehydroepiandrosterone (DHEA) supplements can boost egg and ovarian health in some women with PCOS. 

It is crucial to talk to your doctor to assess the suitability of DHEA supplementation in your specific case.

DHEA should be used cautiously due to potential side effects like hair loss, high blood pressure, rapid or irregular heartbeat, insomnia, and many more.

Engage in low-stress exercise

Regular physical activity can alleviate PCOS symptoms and can positively impact egg quality. 

Engaging in activities like walking, swimming, yoga, or cycling can be beneficial. 

Work with a healthcare professional experienced in PCOS to develop a suitable exercise regimen that suits your abilities and health condition.

Adopt a balanced diet

A balanced diet is essential for promoting overall health and optimizing egg quality. 

Focus on obtaining essential nutrients rather than restrictive diets. 

Include a variety of nutritious foods like leafy greens, fresh fruits, whole grains, and lean proteins (such as poultry, fish, and legumes).

Additionally, add avocados, nuts, and seeds to your diet. 

Consult a registered dietitian to personalize your nutritional needs and ensure you get all the necessary nutrients.

Consider an anti-inflammatory diet

Inflammation is thought to play a role in PCOS and can negatively impact fertility. 

Following an anti-inflammatory diet may aid in fertility and alleviate PCOS symptoms.

This diet typically includes foods rich in antioxidants and anti-inflammatory properties.

Example of an anti-inflammatory diet is lean proteins, high-fiber vegetables and fruits, whole grains, and anti-inflammatory spices like turmeric and ginger. 

Consult a healthcare professional to ensure proper nutrient intake while following an anti-inflammatory diet.

Maintain a healthy weight

Balanced Diet

Weight management is crucial for women with PCOS, as excess body weight can exacerbate symptoms and hormonal imbalances. 

Losing weight through regular exercise and a balanced diet can help regulate ovulation and improve egg quality. 

Consult a registered dietitian or healthcare professional experienced in PCOS management for personalized guidance if necessary.

Cut out tobacco

Quitting tobacco is highly recommended for overall health, including reproductive health. 

Smoking has been linked to numerous adverse effects on fertility and egg quality. 

The toxins in tobacco smoke can harm and potentially destroy egg cells, reducing the egg supply and increasing the risk of early menopause. 

If you smoke, you must consult your doctor for guidance and support in quitting smoking to protect your reproductive health.

PCOS can negatively affect egg quality due to hormonal imbalances, anovulation, follicle abnormalities, and insulin resistance. 

This can lead to difficulties in conceiving and an increased risk of pregnancy complications. However, there are options to improve egg quality. 

Medical treatments like CoQ10 supplementation, L-carnitine and clomiphene combination, and NAC supplementation may help.  Consult a doctor for the best-suited approach as per your needs.

Lifestyle changes, including low-stress exercise, a balanced and anti-inflammatory diet, weight management, and reduced exposure to toxins, can also positively impact. 

By addressing these factors, women with PCOS can enhance their chances of successful conception and healthy pregnancy.
