Birth control pill usage is slowly but inexorably declining as younger demographics start to favor IUDs more; IUDs were virtually unknown circa 2000 but today they're about equal in popularity. If true then we would expect the above trend to reverse within 20 years.

Modern IUDs release hormones.

[kibwen]

They release progestin, not estrogen. And even then they seem to release a 3-7x lower volume of hormones per day than pills.

I also would ask for a source on the relative popularity of the hormonal IUDs vs the non-hormonal copper ones; I haven't seen any source provide that sort of breakdown.

[tachyonbeam]

Progestins suppress testosterone too. I don't have stats but I believe hormonal IUDs are the most popular form nowadays.

Copper IUDs still exist for several reasons and they work pretty well without hormones.
