In previous decades, the ageing process was thought to be correlated with a decline in hormonal function throughout life. Studies were conducted involving the transplantation of animal endocrine glandular extracts into humans.

Hormone levels remain nearly the same. Changes in hormone levels are shown in Table 2.2. Detailed alterations are discussed separately below.
