Near as I can tell, estrogen is synthesized from estrone, and while estrone was originally isolated from the urine, etc. of pregnant women, it is most likely to be synthesized from chemical precursors today, not extracted from urine.

I'm not a chemist or anything but I don't see anything there that appears on first search to be an animal product. petroleum may be another story, but not one I feel confident in answering
