Follicle Stimulating Hormone (FSH) Blood Test

Measures

FSH, a hormone released by the pituitary gland.

Why it matters

FSH signals to the ovaries or testes. Because the pituitary adjusts its output based on feedback from those organs, FSH describes the signal being sent rather than the response.

Before you collect

Cycle timing is critical for women — FSH varies substantially across the menstrual cycle, and day 2–5 is standard unless your practitioner specifies otherwise. Hormonal contraception affects results.

Suits

People working with a practitioner on reproductive hormone questions.

Your next step

Once you have your results, book with a Canwell naturopath, nutritionist or practitioner to talk them through and build a wellness plan that suits you. Book with Canwell
