  Sweating - Wikipedia, the free encyclopedia
The sweat glands are controlled by sympathetic cholinergic nerves which are controlled by a centre in the hypothalamus.
These glands are mainly present in the armpits and around the genital area and their activity is the main cause of sweat odour, due to the bacteria that break down the organic compounds in the sweat from these glands.
Asian people have markedly fewer of these glands compared to white or fl people,[[1]] which is why Asian people generally do not emit such odors and foreigners have a reputation among industrialized east Asians as smelling like animals, irrespective of the foreigners' actual hygenic practices.

Being concentrated in apocrine sweat means that the measured chemical concentration (nanograms/ml) of PSA in apocrine sweat is higher than the measured chemical concentration in the blood from which the apocrine sweat was made.
Apocrine sweat from control individuals would be separated by the same chromatography method and a subtraction of results would be done which would then identify the suspected biomarker protein from the cancer patients.

However, their claims that aquatic mammals lose their apocrine glands and sweat-cool via eccrine glands, and that human sebaceous glands are a waterproofing adaptation, are all contradicted by the facts.
The answer undoubtedly lies in her oft-stated belief that apocrine glands disappear in aquatic species (this is a cornerstone of her version of the aquatic ape hypothesis).
Apocrine glands discharge their contents and these must be replenished before they're used again, while eccrine glands can go on and on.

 Body Odor Support
Eccrine glands are distributed over the entire skin surface and primarily are involved in thermoregulation via sweat production.In contrast, apocrine glands have a limited distribution, involving the axilla, genital skin, and breasts; apocrine elements also commonly are found in the periorbital and periauricular areas.
Apocrine glands have no thermoregulatory role but are responsible for characteristic pheromonic odor.
Excessive eccrine secretion may favor the spread of apocrine sweat and contribute further to bromhidrosis or, conversely, may cause a decrease in odor because the eccrine sweat dilutes the apocrine sweat.

Apocrine chromhidrosis was first described by Yonge in 1709 (1) and later attributed to lipofuscin pigments by Shelley and Hurley in 1954 (2).
Apocrine chromhidrosis usually manifests in puberty when these glands become functionally active and is unrelated to dietary, systemic, or metabolic alterations, gender, occupation, or geographical predisposition (1,2).
Under the microscope, the number of apocrine glands is variable and yellow-brown lipofuscin granules may be observed in the apical area of secretory cells with H and E stain.

Ancestral mammary glands usually are assumed to have produced a copious watery secretion like that of human eccrine sweat glands.
Nevertheless, each of the three populations of cutaneous glands exhibit specializations unlikely to be primitive for the mammary gland.
Consequently, ancestral, prototypic lacteal glands may have had the capacity to synthesize and secrete small amounts of organic substances, as do sebaceous and apocrine glands of living mammals.

 International Hyperhidrosis Society HCP: Physiology of Normal Sweating
Eccrine glands are in higher density on the soles of the feet and the forehead, followed by the palms and the cheeks.[48,57] Apocrine sweat glands are located in limited areas—the axilla and urogenital regions—and produce a thick, odorless fluid that undergoes bacterial decomposition, leading to substances with strong odors.
The ratio of apocrine to eccrine glands is one to one in the axillae and one to ten elsewhere.[48]
