About 5 years ago I had a vasectomy. I have just recently, within the last 6 months, begun learning about Catholicism. I am seriously considering conversion. Can I become Catholic and be in communion with the church, even though I’ve had a vasectomy?
Yes, you can become a Catholic even though you previously had a vasectomy. The Church does not require you to have surgery to reverse it. The sin will be forgiven in either baptism or confession (depending on your particular circumstances).
