The process whose specific outcome is the progression of the primary male sexual characteristics over time, from their formation to the mature structures. The primary male sexual characteristics are the testes, and they develop in response to sex hormone secretion. A biological process whose specific outcome is the progression of an integrated living unit: an anatomical structure (which may be a subcellular structure, cell, tissue, or organ), or organism over time from an initial condition to a later condition. A developmental process by which a progressive change in the state of some part of an organism specifically contributes to its ability to form offspring. Any biological process, occurring at the level of a multicellular organism, pertinent to its function. The process whose specific outcome is the progression of the secondary male sexual characteristics over time, from their formation to the mature structures. In male humans, these include growth of axillary, chest, and pubic hair, voice changes, and testicular/penile enlargement. Development occurs in response to sex hormone secretion. The establishment of the sex of a male organism by physical differentiation. The process by which the Mullerian ducts, primordia of the oviducts, uterus and upper vagina, undergo regression in male embryos. The biological process whose specific outcome is the progression of a multicellular organism over time from an initial condition (e.g. a zygote or a young adult) to a later condition (e.g. a multicellular animal or an aged adult). The establishment of the sex of an organism by physical differentiation. Establishment of a pattern of pigment in males.
