Congenital adrenal hyperplasia mnemonic

Hey, do you know a way to remember the Congenital Adrenal Hyperplasia and it's enzyme deficiencies?

It's the same mnemonic that everyone uses:
The 1 looks like an up arrow for increase

First digit for blood pressure
Second digit for sex hormones

11 hydroxylase deficiency:
1 - BP - High (Hypertension) 
1 - Sex steroids - High (Virilization in females) 

21 hydroxylase deficiency:
2 - BP - Low (Hypotension)
1 - Sex steroids - High (Virilization in females)

17 hydroxylase deficiency:
1 - BP - High (Hypertension) 
7 - Sex steroids - No increase

There was a point in my life where I forgot which digit stood for what. I have a mnemonic for that as well... It's a vulgar mnemonic.
I think of erection, first the blood goes into the corpora cavernosa and then the penis is erect. I remember the sequence of digits by - "First comes the blood, then comes the boner."
First digit - BP
Second digit - sex steroids

An easier alternative submitted by Dev:
Just remember AT
A - Aldosterone
T - Testosterone

I modified it to cat.
