I came across this on the 'Lab Work, Blood Testing and Symptoms' sticky thread.
"Prolactin can be a powerful HPTA inhibitor. We some times see high range, which causes problems and some times very high. Pituitary adinomas do happen and are small cancers. These can increase prolactin and/or decrease gonadotrophins - lowering T. Prolactin can contribute to gynomastia. Older men have an expected age related decrease in gonadotrophins [LH & FSH] and a decrease of testicular production of T when properly stimulated by gonadotrophins.
When younger men loose T levels, prolactin is something that should be tested. If not mid range, a pituitary MRI can be performed to see if there is an imageable adinoma. If an adinoma is larger, it will press on one or more of the optic nerves that pass beside the pituitary gland. If that happens, there can be a loss of peripheral vision... and worse if ignored."
I tried to find more info on this through google but couldn't really find anything. Ever since puberty my 20/20 vision worsened dramatically and i had to get glasses.
Serum Prolactin level: 111 mu/L (<= 550.0)
Obviously my Prolaction level isnt in the mid of the range.
It could be a coincidence ofcourse.
