I get what you're saying, but I think that's an unfortunate conception rather than an immaculate conception. 
It's kind of one of those edge hypotheticals, like a happily married, sexually-active lesbian who has never had penetrative sex with a man gets IVF to have a child. Is that an "immaculate conception" or more specifically a "virgin birth" if a penis was never in the same zip code as her uterus?
I might hypothesize that seminal (including male DNA) penetration would carry the same credentials as penile penetration in canceling out virginity - I'd venture for the Biblical "immaculate conception" a paternity test would have to come up "null" - no human sperm involved.
I'd say this might also fall into the category of placing too much mythical importance on the concept of "physically penetrative virginity" as a measure of a person's worth or a sign of their character as well.
I remember our health teacher once gave us the somewhat cryptic advice: "It doesn't matter so much if an employee makes it to work with everyone on the express train or has to climb up the outside of the building to get into the office; if the employee gets to work he gets to do his job...and you might have a baby."
