What is the reasoning for this? Not following what is "wrong" in the original.
Worth noting is that there is no equivalent term to "female" when referring to men, who are almost always referred to as "men." This is because there is an underlying cultural assumption that men are the default and women are the exception. While the use of the word "female" to describe a woman is not inherently wrong, using the term "woman" is more accurate and respectful, and nobody would use the term "male" to describe a man in the same way.
“Male” is the word, and it is used in lots of books in exactly the same way as it’s being used here.
I have read tons of books that said something along the lines of “he was an excellent male specimen” or “a member of the male species”
Using the word female/male has a specific effect on the way the sentence reads, it gives it a clinical feel and is very useful. Rewriting usages to the approved, politically correct, version just smacks of 1984 style newspeak.
The right example would be "He was a boisterous male."
