How Exercise Affects Fertility

Trying to conceive can feel overwhelming. Hormones. Timing. Supplements. Lifestyle changes.

It’s a lot.

One piece that often gets overlooked in all of this? Exercise.

Not extreme workouts. Not marathon training. Just consistent, balanced movement.

Let’s break down how exercise fits into reproductive health.

What Exercise Does for Reproductive Health

When you move your body regularly:

• Blood circulation improves, delivering oxygen and nutrients to the ovaries, uterus and testes
• Insulin sensitivity improves, which is especially important for some people with PCOS
• Inflammation decreases
• Stress hormones come down

For people with ovaries, exercise can support more regular cycles and ovulation.
For people producing sperm, moderate exercise is linked to higher sperm count, movement and shape, and healthier testosterone levels.

And emotionally? Movement can help you feel more grounded and resilient during what can be a stressful journey.

When More Isn’t Better

Too little movement can negatively affect metabolic and hormonal health.
But too much high intensity exercise can also cause problems.

For people with ovaries, excessive endurance or intense training can:

• Disrupt ovulation
• Lead to irregular or missing periods

For people producing sperm, very intense or prolonged training has been linked to:

• Lower testosterone
• Decreased sperm quality

If you’re undergoing IVF or fertility treatment, intense workouts can also increase the risk of ovarian torsion when the ovaries are enlarged from stimulation medications. That’s why providers often recommend modifying activity during certain phases.

One fertility-friendly goal when exercising? It should leave you feeling energized, not depleted.

What Fertility-Friendly Exercise Looks Like

For most adults, a helpful target is:

150 to 300 minutes of moderate intensity activity per week

That can include:

• Brisk walking
• Swimming
• Cycling
• Strength training
• Yoga

You don’t need to work out every day. Three to five days per week is often enough to support heart health, hormone balance and fertility.

Strength training can be especially helpful for metabolic health, but gentle movement like walking and stretching also counts.

Don’t Forget Rest and Fuel

Rest is not optional. Hormones thrive on balance, and your body needs recovery time to rebuild and regulate.

Fueling your body properly is important too. Undereating can disrupt hormone balance and ovulation.

Your body needs:

• Carbohydrates
• Protein
• Healthy fats
• Fruits and vegetables

Exercise and nutrition work together to support reproductive health.

The Bottom Line

Exercise can be a powerful fertility support when done in the right amount.

In moderation, it helps:

• Circulation
• Hormone balance
• Ovulation
• Sperm quality
• Stress management
• Overall metabolic health

In excess, it can disrupt those same systems.

The goal isn’t perfection. It’s consistency, moderation and sustainability.

If you’re unsure what kind of movement is best for you, especially if you’re preparing for or undergoing treatment, talk with your provider. Together, you can create a plan that supports your body, your hormones and your path forward.

The most effective fertility support is steady, supportive and aligned with what your body truly needs.

How to Move in a Fertility-Friendly Way

• Aim for moderate, consistent movement. Structured exercise programs, including strength training, help regulate menstrual cycles and reduce cardiovascular risk.
• Listen to your body. If exercise leaves you feeling exhausted rather than energized, consider reducing the time or intensity or switching to gentler forms of movement.
• Prioritize recovery. Rest days are just as important as workout days. Incorporate them into your routine to allow your body time to recover and rebuild.
• Fuel your body properly. If you exercise regularly, make sure to consume enough nutrient-dense foods and time your caloric intake effectively to support hormone and reproductive function.
