Vector lookup with 2 criteria

I am looking up values L, M, and S from a seperate worksheet based on two factors. age in months, and gender. I have read enough to figure out how to lookup values L,M,S one at a time using a vectorlookup, from one worksheet to another. However, the LMS values being looked up are for females only. I know I must get the gender codes worked in but not sure how to work this in.
I don't know if I need an and If function, to meet the gender (1male, 2 female) or what.

I am attaching a small example. If anyone could assist, I would appreciate.
