Should she press charges?

My friend is a trans woman, she was born with a penis and testicles though has since been making moves to transition. She has grown her hair out, has has breast implants, everything except the bottom surgery - and she definitely passes for female. You wouldn't know the backstory just looking at her on the street.

Well she went to the pool around a week or two ago (she always does, majorly into swimming) and went into the showers as per usual.

The showers at our local pool are segregated male and female though are communal within that - it's just 2 walls with showerheads coming out of it, no partition or anything. It honestly reminds me of a prison lol

Well she went in there (the female side), got undressed and began showering. After that some woman walked in and yelled a few obscenities (I'm sure you can imagine) before kicking her between the legs.

My friend went to the emergency room the next day after much urging from me and some other friends, and she suffered a ruptured testicle. They said it probably could have been operated on had she went in immediately after, but the delay meant it was too far gone and so it was removed.

She has since been considering pressing charges on the woman who assaulted her, but has some concerns - namely, what if the woman tries to claim she felt threatened, or even outright lie and says my friend tried to assault her and that it was just self defence? Obviously there are no cameras in the showers and as far as I'm aware there are no eyewitnesses, so it would just be one testimony against the other.

Should she go through with trying to prosecute, do you think? Or is it too risky in your opinions?

I understand this is probably not the place for something like this but I spend a lot of time on here and with the amount of political questions and stuff like that I figured asking a more serious question like this would be okay.
