and then tested about 3 months later for testosterone levels and hes still high does this mean he could be a crypt or can it take longer for the testosterone to leave their body??
Testicular testosterone disapears in a matter of hours when the testicle is removed.
High levels in a gelding means that the horse was either improperly gelded (meaning the stallion's testicles were not removed completely. No other scrotal tissue produces testosterone, ONLY the testicles proper), or it means he has a hyperactive adrenal gland.
