beitza "Irishman"

[Douglas G. Wilson]

It is stated at several Websites (including MacBain's dictionary) that Old
Irish "baitsim" = "baptize" or "baptism" (modern Irish "baist[eadh]" I
think). [Pardon me, my ignorance of Irish is virtually total.]

I suppose "non-Jewish Irishman" is similar to "Christian Irishman" which is
similar to "baptized Irishman" ... at least traditionally?

Maybe the testicular connection is just a cute coincidence?
