Testosterone and adrenaline are human hormones. Epinephrine is commonly referred to as adrenaline. It’s a stress hormone made in similar proportions in both women and men. Essentially, testosterone is a male hormone, despite it being made in women in smaller quantities in their ovaries. In males, testosterone helps with physical development, along with sexual performance and capability. Therefore, people who lack testosterone naturally resort to anabolic steroids or similar techniques to boost their testosterone count synthetically.

Adrenaline Function

The adrenal glands, which are positioned above the kidneys, make adrenaline. The hormone is commonly referred to as epinephrine in the medical and scientific communities. And it’s also often referred to as “flight or fight” hormone, as its release is subjected to threat or severe stress. Adrenaline increases respiration rate, heart rate, availability of glucose and blood flow for fueling muscles, so that the body is prepared to flee or fight when under attack.

Testosterone Function

In females and males, testosterone drives sex drive. In men, the hormone is made in testes’ Leydig cells. In women, on the other hand, the ovaries’ thecal cells make limited testosterone amounts. The hormone helps embryonic boys with male sex organ development, and later during puberty, the hormone causes these sex organs to increase in size and gain complete potential.


Since both adrenaline and testosterone are linked with vigor and energy in some levels – as testosterone can lead to increased adrenaline and musculature and which temporarily increases the muscles’ contractile strength – it is common to conclude that the hormones work in pairs. However, in reality, the testosterone hormone exerts long-term impact on physiological and development function. On the contrary, adrenaline’s effects are short-term and which do not cooperate with testosterone.


Though, in several ways, the functions of adrenaline and testosterone do not significantly overlap, according to a research study made public in 1983, high adrenaline levels in the body could negatively influence men’s testosterone levels. This is courtesy the decreasing LH levels, which reduces testosterone levels subsequently. Though exposure to adrenaline for the short term won’t cause major effects, routine adrenaline exposure and long-term stress could down-regulate the production of testosterone.

Expert Thoughts

Both adrenaline and testosterone levels could spike up shortly after or during exercise. Adrenaline release happens when indulging in major physical activities, and it helps augment muscular strength temporarily. Typically, this effect stays for only a short time period post and during a workout.
