PCO and Fertility: How Polycystic Ovaries Affect Pregnancy and IVF Success Rates

April 15, 2026

PCO, or polycystic ovaries, is one of the most common conditions affecting women of reproductive age. Many women are told they have PCO during a routine ultrasound, often without fully understanding what it means for their fertility. While PCO can be associated with irregular cycles and difficulty conceiving, the good news is that most women with PCO can achieve pregnancy with the right approach.

At Azoury IVF Clinic, with more than 40 years of experience and tens of thousands of IVF and ICSI cycles performed, we have extensive expertise in managing PCO-related fertility challenges. As one of the highest-volume standalone IVF centers worldwide, our advanced embryology lab, cutting-edge technologies, and personalized care allow us to achieve excellent IVF success rates even in complex PCO cases.

Understanding PCO is the first step toward taking control of your fertility journey.

What Is PCO

PCO refers to the presence of multiple small follicles in the ovaries, often seen on ultrasound. These follicles are not harmful themselves but reflect a pattern of ovarian activity that may be associated with hormonal imbalance.

It is important to distinguish PCO from polycystic ovary syndrome, as not all women with PCO have hormonal symptoms. However, PCO can still affect ovulation and fertility.

Women with PCO often have

  • Irregular ovulation
  • Delayed cycles
  • Difficulty predicting fertile windows

At Azoury IVF Clinic, we carefully evaluate whether PCO is simply an ultrasound finding or part of a broader hormonal condition affecting fertility.

How Does PCO Affect Fertility

PCO can impact fertility primarily by affecting ovulation.

In women with PCO

  • Ovulation may be irregular or absent
  • Egg maturation may be disrupted
  • Hormonal imbalance may interfere with reproductive function

This means that even though the ovaries contain many follicles, the process of releasing a mature egg may not occur regularly.

At Azoury IVF Clinic, we frequently treat patients with PCO who experience delayed conception due to ovulatory dysfunction.

PCO and Ovulation Problems

Ovulation dysfunction is the main reason PCO affects fertility.

In PCO

  • Follicles begin to develop but do not reach full maturity
  • Ovulation may not occur
  • Cycles become irregular

This can make natural conception more challenging. However, with appropriate treatment, ovulation can often be restored.

PCO and Egg Quality

A common concern is whether PCO affects egg quality.

In most cases, egg quality in women with PCO is preserved, especially in younger patients. However, hormonal imbalance and metabolic factors may influence egg development in some cases.

At Azoury IVF Clinic, careful stimulation protocols are used to optimize egg quality and improve IVF success rates in women with PCO.

PCO and IVF Success Rates

PCO patients often respond very well to IVF because of their high number of follicles.

However, managing PCO during IVF requires expertise to avoid complications such as ovarian hyperstimulation.

At Azoury IVF Clinic, IVF success rates in PCO patients are optimized through

  • Individualized stimulation protocols
  • Careful monitoring
  • Advanced embryo culture techniques
  • Freeze-all strategies when needed

With the right approach, women with PCO often achieve excellent outcomes.

PCO and Risk of Ovarian Hyperstimulation

One of the key considerations in PCO patients undergoing IVF is the risk of ovarian hyperstimulation.

Women with PCO are more sensitive to fertility medications and may produce a high number of eggs.

At Azoury IVF Clinic, we use advanced protocols to minimize this risk and ensure patient safety while maintaining high IVF success rates.

Treatment Options for PCO

There are multiple fertility treatment options available for women with PCO.

Lifestyle modifications

  • Weight management
  • Healthy diet
  • Regular exercise

Medical treatments

  • Ovulation induction medications
  • Hormonal regulation

Advanced fertility treatments

  • Intrauterine insemination
  • IVF and ICSI

At Azoury IVF Clinic, treatment is always personalized based on the patient’s specific condition and fertility goals.

When Should Women with PCO Consider IVF

IVF may be recommended in PCO patients when

  • Ovulation induction fails
  • There are additional fertility factors
  • Age is a concern
  • Time to pregnancy is critical

At Azoury IVF Clinic, we guide patients toward the most effective fertility treatment options to maximize success.

Related FAQs

  • The IVF success rate depends on the age of the woman and the cause of infertility. The success rate reaches 70% for every embryo transfer attempt in women younger than 35 years. In vitro fertilization leads to a live-birth in 90% of cases if the couple does not give up.

  • All recent studies show that a woman can get back to her normal life directly after transfer. She can climb stairs, kneel to catch things from the floor, drive for a long distance, take a shower, sleep in any position, catch a flight…

  • This is the question that no IVF specialist can answer. If we knew the cause that will lead to failure, we would have solved it before transferring the embryos. We can only make assumptions about the causes. Embryo implantation in the uterus is a very complex process and multiple factors are involved. We can monitor and control all the factors we know about, like endometrial thickness, the timing of transfer and the absence of uterine problems. Other factors like immunity are known to play a role but cannot be controlled. The majority of factors remain unknown. Whether we like it or not, we always do our best but the final outcome is in God’s hands.

  • IVF is a multiple step procedure. The first step, ovarian stimulation, consists in daily hormonal injections for a period that varies between 8 and 12 days. Of course injections are burdensome, but some people require taking injections daily all their life so few days of injections are not a huge deal. The second step is oocyte pick up. It is performed under sedation and it is a painless procedure. The pain after the procedure is similar to regular period pain. The last step is embryo transfer, that takes less than a minute and that does not require any sedation as it is similar to any gynecological check up.

  • The urine pregnancy test cannot detect pregnancy very early. The pregnancy hormone, bhcg, appears in the blood before it appears in the urine. Blood test needs at least 12 days post-transfer to detect pregnancy. So there is no point in doing a home pregnancy test before that.

  • The goal of this step is to have a high number of eggs (more eggs = more embryos = more chances of having a baby). Each cycle, a woman generally ovulates only one egg. This egg can be of good or bad quality; it can get fertilized by the sperm or not; the embryo obtained can undergo normal early development or not; it can implant or not. Hence, when we undergo a burdensome IVF cycle, we stimulate the ovaries using hormonal injections in order to obtain the biggest number of eggs possible and have better chances in obtaining a good embryo that will lead to a pregnancy.

  • Definitely not! And this is a general misconception! Each day a different group of follicles starts growing in a woman’s ovaries. The recruitment of these follicles and their first phase of growth are independent from hormones. When these follicles reach a certain size, their growth becomes dependent on hormones. The biggest and strongest of these follicles starts “taking all the hormones” produced by the woman’s body and continues to grow alone while the other follicles do not have “enough hormones” and die. The injection of hormones used during ovarian stimulation saves these follicles from dying but does not lead to recruiting more oocytes from the ovaries.

  • Using ultrasound, the doctor can see the follicles and follow up on their growth. The follicles are not the eggs, they are the “bags” that contain the eggs and help them become competent. It is impossible to see the eggs by ultrasound. Some follicles are empty and that’s why there is very often a difference between the number of follicles seen by ultrasound and the number of oocytes retrieved during oocyte pick-up for IVF.

  • Thousands of clinical trials have been trying to answer this question. It is admitted that hormones that are injected during ovarian stimulation are not toxic and are unlikely to cause cancer. On the other hand it is strongly believed that hormones promote cancer in people that are suffering from it without knowing.
