Intermittent fasting is an emerging field with a growing range of health benefits including weight loss, better blood sugar regulation, improved hormone levels and a healthier gut. As time restricted eating (TRE) has a positive effect on many parts of the body, including female reproductive systems, there is potential that it could influence sperm production, however, this has not yet been investigated.

This trial involves intermittent fasting for a period of 3 months and assessing sperm quality before and after to look for any changes.

We would provide two free of charge semen analysis, plus MiOXSYS testing for seminal oxidative stress which would usually cost more than £500.
