Question

I need to know if hormones are present in sweat or not.

more specifically, hCG hormone or other hormones associated with pregnancy such as estriol, estrogen or any others.

any help would be much appreciated

Answer 1

Probably some, why would you ask? There's a reason they use urine or blood for pregnancy tests.

Answer 2

SWEAT - Sweat contains mainly water. It also contains minerals, as well as lactate and urea. Mineral composition will vary with the individual, the acclimatisation to heat, exercise and sweating, the particular stress source (exercise, sauna, etc.), the duration of sweating, and the composition of minerals in the body. An indication of the minerals content is: sodium 0.9 gram/liter, potassium 0.2 gram/liter, calcium 0.015 gram/liter, magnesium 0.0013 gram/liter. Also many other trace elements are excreted in sweat, again an indication of their concentration is (although measurements can vary fifteenfold): zinc (0.4 mg/l), copper (0.3 - 0.8 mg/l), iron (1 mg/l), chromium (0.1 mg/l), nickel (0.05 mg/l), lead (0.05 mg/l). Probably many other less abundant trace minerals will leave the body through sweating with correspondingly lower concentrations. In humans sweat is hyposmotic relative to plasma

HCG

After the egg has been fertilised,  it becomes embedded in the wall of the uterus, (see article on becoming pregnant).  This implantation takes place about 8 days after the impregnation.  This action has the effect of releasing the hormone ß-hCG.  It is this hormone that is tested for in home pregnancy tests.

ß-HCG encourages the "yellow body" (corpus luteum) to produce progesterone and estrogen during the early stages of the pregnancy.  This situation remains the same for the first trimester of pregnancy, the placenta will eventually replace the function of the "yellow body" by producing its own progesterone, thus the levels of ß-HCG will drop back quickly in the second trimester to between 10% and 30% of the peak levels.
