Thyroid health and female fertility: why blood testing matters

It’s not a hormone most people think about when planning for pregnancy, but the thyroid plays a quiet, important role in fertility. Nestled in the neck, this small gland affects everything from energy levels to menstrual cycles.

Understanding your thyroid test results chart

If you’ve ever had a thyroid function test (TFT), you’ve probably stared at a confusing lab report filled with markers like TSH, FT4, and FT3, and wondered what on earth it all means.

Testosterone plays a vital role in nearly every system of the body, including the cardiovascular system. And for men, especially as they age, low testosterone may signal more than fatigue or low mood.

Exercise is good for you, until it isn’t. Most of us are told to move more, train regularly, and push ourselves to get stronger and fitter. But there’s a limit. And for men who regularly train at extreme intensity and volume, consistently going beyond that limit may quietly chip away at one of their most important hormones.
