On the Sims 2 can a man become pregnant if....?

Okay I was playing the Sims 2 on my laptop last night and my male sim was looking through the high powered telescope when he got abducted by aliens. He came back and the next morning he vomitted into the toilet and he had a bubble above his head that had a baby pacifier and a question mark in it. Did my Sim get inpregnated by aliens? I know when your female Sim is pregnant she has morning sickness... So is my male Sim pregnant? Has this happened to anyone else?
