Why Fertility Testing Should Look Wider
Hormones matter, but so do the wider health systems that support reproductive wellbeing.
Thyroid function
Thyroid health can play an important role in reproductive wellbeing.
Vitamin status
Nutritional markers including folate, B12 and vitamin D support fertility and pre-conception health.
Inflammation and metabolic balance
Inflammation, metabolic balance and general health can all play an important role.
Beyond a narrow snapshot
A broader panel helps move the conversation beyond a narrow hormonal snapshot.
