johnthurtjr FTR I had no idea this was a thing, and was pretty disappointed in myself when the google search had it in big bold letters right in my face. +3

drdoom via @johnthurtjr link: "Testosterone and other androgens have an erythropoietic stimulating effect that can cause polycythemia, which manifests as an increase in hemoglobin, hematocrit, or red blood cell count." https://www.medscape.com/viewarticle/773465 +3

meningitis I guess that's another reason for steroids and doping up. +7

drschmoctor For once I feel like I've been led astray by Pathoma. My instinct was to go with hemoglobin, but I talked myself out of it after remembering Dr. Sattar saying that the reason why women have lower hemoglobin is due to menstruation. +2

hysitron I guessed this one cause men have a higher hemoglobin than women. +10

notadoctor High levels of testosterone will result in amenorrhea. I guessed that since she's not menstruating she will not be losing blood and therefore hemoglobin. Therefore her hemoglobin levels will be higher than expected. +5

meningitis It kinda makes sense knowing testosterone causes catabolism so I was in between Alkaline phosphatase and hemoglobin... +1

enbeemee isn't testosterone anabolic? +4

syoung07 ALK phosph is indicative of osteoclast activity. Testosterone keeps male bones strong just like estrogen does for women. Testosterone builds bone (osteoblast activity) therefore we would not see a rise in ALK phos +

uworld says somewhere that testosterone increases hematocrit, increases LDL, and decreases HDL

passplease Estrogen increases HDL. Testosterone is converted into estrogen. Why doesnt testosterone increase HDL. Why is my logic wrong? +

avocadotoast The woman in this vignette has an increased androgen:estrogen ratio, so the effects of testosterone on lipid levels will be greater than those of estrogen on lipid levels. Boards and beyond also states that testosterone causes an increase LDL, decreased HDL, and increase in hematocrit, which is why males with primary hypogonadism can present with anemia and the use of anabolic steroids can present with erythrocytosis. +

btl_nyc The increased testosterone is metabolized by granulosa cells to estrogen and by adipose tissue into estrone. Both feed back on the hypothalamus to inhibit FSH & LH secretion, but FSH is much more sensitive to feedback inhibition than LH, causing an increased LH/FSH ratio. +1

Men generally have a higher RBC mass (hematocrit, hemoglobin, etc) and it is thought to be attributed to higher testosterone levels. She has high testosterone so you can assume the same for her. This is in Zanki, so it must be in FA or Pathoma.

For all wondering why testosterone doesn’t cause an increase in alk phos, I found this article that basically says men with low testosterone have high alkaline phosphatase and weak bones.

It's an anabolic hormone, muscle mass, RBC mass will increase.
