“so the concern over this possible problem is genuine. ”
I dont fully understand this? why the concern? Just because it is new ?
I saw a new Oreo flavor “Apple Cider Donut Sandwich” To the best of my knowledge NO study has been done to know whether or not the cookie has any effect on fertility .So it would seem that the concern over this possible problem is genuine.
So here is the easy, halachic question: Is a person who loses fertility by eatign the cookie, and therefore loses the ability to carry out the mitzvah to be fruitful and multiply, in breach of halacha for eating the cookie?
