Anti-Mullerian hormone (AMH) is a protein produced by granulosa cells of the ovaries in females and by Sertoli cells of the testes in males.
In women serum AMH concentration increases with age up until the mid-twenties, after which it begins to decline. AMH correlates well with the number of follicles in the ovary (as measured by ultrasound) in women over the age of 25 and its measurement is used to individualise fertility treatment.
In men serum AMH concentration tends to be high in childhood, then declines through puberty to low levels in adulthood. It is used in the investigation of cryptorchidism and anorchidism.
AMH is elevated in the majority of patients with granulosa cell tumours and may be used to monitor disease progression or recurrence. AMH is also useful in the investigation of disorders of sex development as a marker of testicular activity.
