Yes, but that is not really why the birth rate is dropping. The cause is that more women are choosing (who can choose, really) to not have children, or to have fewer children.

And logistically, there wasn't really widespread access to reliable birth control before 1950.

Citation needed. As far as I know that is a wingnut paranoia point and not supported by the data.

Edit: Looks like I've been missing the story on this one.

Interesting that the articles all talk about obesity, unknown chemicals, brief style underwear, and whatnot as a possible cause without stopping to consider that maybe societal attitudes towards masturbation may play a role.

Here's one after a 10 second google for "sperm rates in men"

This article displays pretty much all that is wrong with the reporting on this. A lot of talk about vaguely related sensational commentary, very little on the practical significance (if any).

This is just an well established fact. Sperm count in industrialized nations have dropped considerably over decades.

Uh, no.

Really? Masturbation? Come on.

Just as plausible as any of the other theories they put forth in those articles. Lots of shoulder shrugs from what I saw.
