Last February, scientists at the Uppsala University, Sweden conducted a study on the effect of estrogen-like pollutants on male born frogs. Two species of frogs were exposed to such pollutants with less than 50% of them being females. The population that received the heaviest dose of estrogen became 95% female in one case and 100% in another. Pollutants used in the study are similar to the ones in the environment (in pesticides, industrial wastes, etc). Because of its effect on frogs, I wonder if it might be possible that these same pollutants can affect the male humans and might also lead to the extinction of the male species entirely.

Frogs are somewhat different from humans, or other mammals. Many species of frogs have always had the ability to change sex in response to environmental triggers. This sounds like a similar event to me.

Male is not a species.

The frogs are effected because they have to live in and absorb polluted water through their skin. The same doesn't happen for human males.
