How PCOS Affects Ovulation and Fertility
PCOS primarily affects a woman’s ability to ovulate regularly, which in turn can reduce fertility. Ovulation is crucial for conception, but in women with PCOS, hormonal imbalances can prevent the regular release of eggs, making it harder to get pregnant.
Here are some key fertility challenges faced by women with PCOS
- Timing Difficulties: Since ovulation is irregular, predicting the best time for conception becomes harder. Tracking ovulation can be a challenge.
- Lower Frequency of Ovulation: Women with PCOS may experience less frequent ovulation, which can reduce the chances of conception.
- Hormonal Environment: The hormonal imbalances in PCOS, such as elevated insulin and androgen levels, can create an unfavourable environment for implantation and early pregnancy development.
Menstrual Cycle Disruption
Irregular periods are one of the most common symptoms of PCOS. This happens due to irregular ovulation (anovulation), where the ovaries don’t release an egg or release them irregularly each month.
For women trying to get pregnant, this can make predicting ovulation tricky and limit the chances of fertilisation. However, this doesn’t mean pregnancy is impossible—it will require more effort checking with scans and tracking.
Hormonal Imbalances and Their Impact
Women with PCOS often have higher levels of androgens (male hormones) like testosterone, which can affect the normal balance of reproductive hormones. This hormonal imbalance can interfere with the growth and release of eggs from the ovaries, leading to the formation of multiple small cysts.
Insulin resistance, another common symptom of PCOS, further disrupts hormonal balance. 65% to 70% of Indian women with PCOS exhibit insulin resistance, which increases fertility issues. Fortunately, managing these hormonal imbalances through treatment can significantly improve fertility.
Luteinizing Hormone (LH) levels in PCOS are often consistently elevated, disturbing the normal balance between LH and Follicle-Stimulating Hormone (FSH). FSH helps eggs develop in the ovaries, and a spike in LH causes ovulation. However, hormonal imbalances disrupt this process, making ovulation less likely to happen regularly.
