The evolution of perennially enlarged breasts in women: a critical review and a novel hypothesis

It is proposed that breasts appeared as early as Homo ergaster, originally as a by‐product of other coincident evolutionary processes of adaptive significance, including an increase in subcutaneous fat tissue in response to the demands of thermoregulatory and energy storage, and of the ontogenetic development of the evolving brain.

Gynaecomastia—pathophysiology, diagnosis and treatment

Gynaecomastia (enlargement of the male breast tissue) is a common finding in the general population, and administration of androgens might be helpful, as might antiestrogen therapy in men with endogenous overproduction of estrogens.
