The very article we're discussing? Remember, it shows 7 times as many women give up as men do.
A generalization is not contradicted by one example to the contrary, it would need a majority of examples to the contrary. Obviously some men do give up. But only 1/7th as many as with women. I am simply supporting the explanation someone else offered: that this is because women have inherent value and men's value is purely based on their current level of success. So men have an additional strong incentive to not give up. And when they do give up, it is often just to pursue another avenue where they feel success is more likely, rather than just giving up altogether.
