Understanding fertility involves more than simply assessing reproductive organs. Hormones play a central role in ovulation, egg quality, sperm production, stress response, thyroid function, and overall reproductive health. Hormonal imbalances can affect both women and men and may contribute to difficulties with conception, irregular cycles, low fertility potential, or pregnancy challenges.
The Fertility Test is a comprehensive at-home fertility profile designed for both women and men to provide deeper insight into reproductive hormone balance and factors that may influence fertility health. This advanced profile evaluates 15 key hormones and biomarkers associated with fertility, thyroid function, stress response, and hormone regulation to help identify potential underlying issues affecting reproductive wellbeing.
Suitable for individuals trying to conceive, experiencing hormonal symptoms, or wanting a clearer understanding of reproductive health, this profile may provide valuable information before making lifestyle, nutrition, or fertility treatment decisions.

- Hormonal symptoms
