Summary of Rebecca M. Jordan-Young & Katrina Karkazis's Testosterone

#1 The definition of testosterone is a hormone made in the testes that stimulates the development of male sex organs, secondary sexual traits, and sperm. However, this definition is misleading, because it makes it seem like T is only made by male bodies for male traits.

#2 The importance of context is crucial when discussing the singularity of T. T is a multiplicity that exists in bodies, and it is in a constant flow of generation and transformation. It is not just found in sex organs, but everywhere else throughout the body.

#3 The first step in the research process is to choose which qualities or behaviors to define aggression. Researchers then have to decide which T to use and how to measure it. T can be extracted from blood, muscle, or other tissues, and it is also found in urine and saliva.

#4 The aggression domain is where salivary T has been used the most. It is a good substitute for testosterone in blood, and it is easier to obtain large numbers of people to participate in studies if they don’t need to have blood drawn.

#1

The definition of testosterone is a hormone made in the testes that stimulates the development of male sex organs, secondary sexual traits, and sperm. However, this definition is misleading, because it makes it seem like T is only made by male bodies for male traits.

#2

The importance of context is crucial when discussing the singularity of T. T is a multiplicity that exists in bodies, and it is in a constant flow of generation and transformation. It is not just found in sex organs, but everywhere else throughout the body.

#3

The first step in the research process is to choose which qualities or behaviors to define aggression. Researchers then have to decide which T to use and how to measure it. T can be extracted from blood, muscle, or other tissues, and it is also found in urine and saliva.

#4

The aggression domain is where salivary T has been used the most. It is a good substitute for testosterone in blood, and it is easier to obtain large numbers of people to participate in studies if they don’t need to have blood drawn.

#5

There are seasonal variations in testosterone, but they aren’t universal. Some people have very low levels of testosterone at one point, but later have a perfectly normal testosterone profile.

#6

The timing of a T study may need to account for whether the underlying mechanism of interest is likely to go through the slower classical pathway or the faster non-genomic pathway. The non-genomic pathway is likely to be most important for emotional and behavioral effects.

#7

T is never just T. It is always bound to sex hormone binding globulin, or SHBG, or albumin, a protein. Free T is the unbound portion of T. Researchers must choose between many laboratory techniques to analyze the samples, and they must choose which substance to study in other research they want
