I wonder what the chemical stability differences are (temporal-wise,
pH-wise, temperature-wise, etc.) between estrogen and testosterone?

If estrogen degrades proportionally faster than testosterone does
over time.....
well, the researchers may come to the conclusion that *all* of our
(very regular) ancestors were male!
Does THAT fit with the Republican Party's idea of a wholesome and
