Polycystic Ovary Syndrome (PCOS) is one of the most prevalent endocrine disorders among women of reproductive age. It is primarily characterized by insulin resistance, leading to elevated insulin levels and an overproduction of androgens like testosterone. This hormonal imbalance disrupts normal ovulation, resulting in the formation of ovarian cysts and ovulation disorders. These ovulatory issues are a significant cause of infertility in women with PCOS, as they lead to infrequent or absent ovulation, poor egg quality, and a less receptive uterine lining, further reducing the chances of conception.
Women with PCOS often have difficulty getting pregnant and may experience symptoms like weight gain, acne, and extra hair growth. Although weight loss can improve these symptoms and enhance fertility, it can be difficult for women with PCOS, as they tend to gain weight more easily and struggle to lose it.
Despite the challenges, several effective treatment options are available for women with PCOS who wish to conceive. The first step of treatment typically involves lifestyle modifications, including weight loss, a balanced diet, and regular exercise. These changes can improve insulin sensitivity and restore hormonal balance, potentially leading to regular ovulation. When lifestyle changes alone are not enough, medical interventions may be necessary.
Ovulation induction is a common treatment strategy for women with PCOS-related infertility. Medications like clomiphene citrate (Clomid) or letrozole are commonly prescribed to stimulate ovulation by encouraging the ovaries to release one or more eggs, thereby increasing the chances of conception. Ovulation induction can be particularly effective for many women with PCOS, especially when it is combined with lifestyle changes such as weight loss and regular exercise. However, the success of ovulation induction can be low, and it may take several cycles to achieve pregnancy.
If ovulation induction fails after multiple attempts, IVF is usually the next step. IVF significantly increases the chances of a successful pregnancy for women with PCOS. However, because of the greater number of eggs that can develop during ovarian stimulation, women with PCOS are at risk of developing Ovarian Hyperstimulation Syndrome (OHSS). OHSS is a condition where the ovaries become enlarged and painful, frequently accompanied by fluid accumulation in the abdomen. Symptoms can range from mild discomfort to severe pain and potentially serious complications. To prevent OHSS, doctors may adjust medication doses, use a “freeze-all” approach where all embryos are frozen for later transfer.
Frozen embryo transfer (FET) is often the preferred choice for women with PCOS. Studies have shown that FET can lead to higher pregnancy rates and better outcomes compared to fresh embryo transfers. This is largely because FET provides a more optimal uterine environment and reduces the risk of complications, making it a preferred option for many patients.
