Why does it have to be a male? Yes I typed trail instead of trial. Was tired. Had been up all day working and posting. Please forgive my mistype.
It is not necessarily male. The noun is of indeterminate sex and and the non-PC version of English rule is that a subject of unknown sex takes the masculine. If you accept PC English and insist on using it then ultimately you will not be able to write or say anything that means anything. That is the aim of PC English, to befoul the language and render communication futile.
