I know that is a spanish question, but Portuguese like a latin language is similar in some words but only exists- Assistente
And is used like a word that have the same meaning in Masc. and Fem.
The women; A assistente
The men; O assistente
Thanks for the question I was a few moments ago thinking in some meanings that are neutral word´s and this is one of them. Cause is not necessary to use a Masc or Fem article. Thanks again

Se oye mejor usando el articulo La, para definir que se trata de una mujer, porque la verdad asistenta, se oye muy feo.
