Can Diabetes Affect Your Fertility? Understanding the Impact and What to Do Next
Diabetes can affect systems throughout the body, yet its impact on fertility is often overlooked. Both type 1 and type 2 diabetes can lead to high blood sugar levels, which can influence reproductive hormones, egg and sperm health, and even the earliest steps of pregnancy. However, with the right care, many people with diabetes go on to conceive and carry healthy pregnancies.
How Diabetes Affects Fertility in Women
When blood sugar runs high, the body often produces extra insulin to compensate. Over time, many people — especially those with type 2 diabetes — develop insulin resistance, meaning their cells don’t respond to insulin as they should. This creates a cycle of elevated insulin and unstable blood sugar. When insulin levels remain consistently high, it can disrupt the hormonal balance needed to maintain regular ovulation. Without regular periods, it can become difficult to achieve conception.
Additionally, chronic high blood sugar can lead to inflammation and create oxidative stress, both of which are known to negatively impact egg quality and even embryo implantation, all of which can impede conception.
How Diabetes Affects Fertility in Men
In men, high blood sugar and insulin resistance can affect testosterone levels, resulting in lower sperm count and reduced sperm quality. Oxidative stress caused by high blood sugar has been found to damage sperm DNA, which can impede fertilization or increase the risk of miscarriage. Over time, diabetes may also harm the nerves and blood vessels involved in sexual function, leading to erectile dysfunction.
Improving Fertility With Diabetes
Managing diabetes doesn’t mean putting your family-building plans on hold. With the right strategies and support, many of the factors that affect fertility can be improved. Here are a few steps that can help strengthen your reproductive health while living with diabetes.
Consistent Blood Sugar Control
Keeping blood sugar in a healthy range supports hormone balance, egg and sperm quality, and implantation. This may include:
- Tracking glucose regularly
- Adjusting insulin or medications
- Working closely with an endocrinologist or diabetes educator
Prioritize Nutrition and Movement
Aim for balanced meals that combine protein, fiber, and healthy fats to prevent rapid spikes in blood sugar.
- Choose slow-digesting carbohydrates (like whole grains, beans, and vegetables) more often than refined ones.
- Eat on a consistent schedule to support stable glucose throughout the day.
- Move regularly, even in small ways, such as a 10–15 minute walk after meals which can help lower post-meal blood sugar.
- Incorporate both cardio and strength training, as building muscle improves insulin sensitivity over time.
You don’t need to overhaul your routines all at once — small, steady adjustments often make the biggest difference over time.
Consider Seeing a Fertility Specialist
For people with diabetes, meeting with a fertility specialist can help pinpoint reproductive challenges and help you determine whether assisted reproductive treatments may be helpful. A fertility specialist can review your diabetes history, assess ovulation, run hormone panels, and evaluate sperm health to see where your fertility may be impacted. Depending on your unique situation, your provider may suggest ovulation-inducing medications and/or treatments such as IUI or IVF, all of which have supported many with diabetes towards conception and healthy pregnancies.
