Endurance training leads to low testoterone in men, low fertility in women

By now, we all know that exercise is a good thing. But if you're only running or cycling for distance without hitting the weights, you could be doing damage to your sexual performance.

A recent study in the European Journal of Applied Physiology found that intense endurance exercise can cause low testosterone and lowered sex hormone levels in men, which translates into poor reproductive health and low fertility.

Previous studies found comparable fertility issues in women whose fitness routines are endurance focused, most commonly manifested in impaired menstrual cycles.

The good news is, this can be fixed - by getting off the street, spin class, or treadmill, and into the weight room.

Strength training can help reduce these symptoms by improving hormone levels to help counter the stress from cortisol and related catabolic hormones that cause inflammation and damage to the reproductive organs.

Research suggests there is a middle ground to reproductive health such that individuals who like to run and cycle can improve their fertility and overall health by incorporating strength training.
