Actually no need to speculate as science has already answered that question. That is, it has nothing to do with what we produce naturally and everything to do with a certain inherited gene. About 30% of males are unable to smell androstenone due to the lack of a particular gene:

But thirty percent of people had a variation of the gene (OR7D4 WM) that made a receptor into which the androstenone could not fit. The difference in the receptor was very small Gene l — just two amino acids differed — but the effects were pronounced. Those with the functional copy were eleven times more sensitive to androstenone than their counterparts. And that marked the first proof that a particular gene was responsible for a person’s ability to smell a certain odor.
