Irenaeus was a "dancer", doing his best to play both sides (Rome and Polycarp-from-apostles) on a number of issues.
He says, " But Eve was disobedient; for she did not obey when
as yet she was a virgin." And we all know Eve gave birth to children (plural).
So too he says of Mary, " And on this account does the law term a woman betrothed to a man, the wife of him who had betrothed her, although she was
as yet a virgin; thus indicating the back-reference from Mary to Eve"
And so knowing too about the brothers of Christ.
He compares, " For what the virgin Eve had bound fast through unbelief, this did the virgin Mary set free through faith."

He calls them both virgins, but knows they both gave birth. Elsewhere in his writings he seems to argue for the ever-virgin idea.
"Ignatius" too picks up the birth-from-Mary's-side idea.
For the body of Adam was made out of the four elements, and that of Eve out of the side of Adam. And, indeed, the altogether
peculiar birth of the Lord was of a virgin alone.
