Understanding the marker
FSH is made by the pituitary gland at the base of the brain. It helps regulate egg development in the ovaries and sperm production in the testes.
FSH is interpreted with related hormones and the reason for testing. Age and hormone treatment matter. If menstrual-cycle timing is relevant, use the planned collection instructions and the recorded cycle information.
What does high FSH mean?
A high FSH result can reflect a stronger signal to the ovaries or testes. Its meaning depends on age, related hormones and confirmed reproductive or treatment context. It is not a diagnosis by itself.
What does low FSH mean?
A low FSH result can reflect reduced hormone signalling or the effect of hormone treatment. Related hormone results and symptoms help determine whether it is expected in the circumstances.
