Well said Inglorious!
After 2 years just to hear the words I am pregnant from my wife and complications during the 9 months she was pregnant you better believe I was going. IMO your man card should be removed for not going if it is yours.
I agree with Inglorious as well
That being said the only times (twice now) that I've gone to a baby shower (that weren't for my own kids) was to be the excuse as to why my wife had to leave early .... she's not big on them herself (lucky me). Other than that ... she'd never ask.
