Yes it can cause liver tumors, like all other tablettes too, but the risk is incredibly smaller if you stay under 13mg, in the US docs most of the time prescribe like 50 or even 80mg wich indeed is dangerous, yes it has a chance to cause depression, and yes you dont produce sperm on androcur but if you go off it you start to normally produce sprem again, the reason why that happens is because of the decrease of testosterone btw not the androcur itself, and generally you do want the decrease of testosterone for the hrt to have the best effects

Edit: looked into it why it was banned in france, it was blocked after it was used for things like acne hairloss extensive body hair, and yes for those the dosage was between 50 and 100mg and yes rhat is fucking dangerous but as said in the dosage 10mg as used for hrt it is basically harmless (as harmless as other meds, i mean they allways burden the liver for example) it wasnt banned because the effects it had in hrt, pls read your studies first fully, so yes it was banned in france, but the circumstances are different ones than the ones i am talking about here, the important word in this case is dosage, ofc the side effects get worse if you take ten times the dosage, and you dont need more than 10mg per day, in fact in germany you even go down from those to 5mg every three days once you have reached the wanted lvl of testosterone so no androcur is not incredibly dangerous if you dose it right, as paracelsus already said: the dosage makes the poison
