The other day whilst masturbating i noticed a small hard lump on my left testicle. i checked later on and it wasn't there. but it did return next time i masturbated i am slightly worried about this. can anybody advise me or inform me?
thank you

it may be your epidymis which produces your sperm! these are small lumps on top of your testes and sometimes get mistaken for cancerous tumours.
