Learn English – pejorative/offensive slang word or phrase for a man who suffers from erectile dysfunction

From the article:

"The club have produced a handbook which highlights common slurs against race, religion, sexual orientation, gender and disability which could cause offence."

Man up, along with a phrase such as You play like a girl, imply that it is better to be a man/male and worse to be a woman/female. Would you tell a woman to "man up?" Using a masculine descriptor as a positive or the feminine as a negative is rather insulting to females/women. Similarly, the club has banned "gay" as an insult, as implying being gay is a bad thing is offensive to actual gay people. Same thing for racial epithets, which the club has already had an issue with.

A friend of mine coined(?) the phrase "grow some ovaries," which I personally like to use.
