In reply to estrogen and depression, posted by bubblegumchewer on August 12, 2002, at 19:16:21
Actually in human females both progesterone and estrogen decline to very low levels before a period. The highest levels are at ovulation mid-cycle. Its true that progesterone is slightly higher but they both decline to really really low levels.
They find no difference in hormone levels between normal people and people with severe PMS. So they think instead it could be either that some are more sensitive to the decline or that in some the levels decline faster and it is actually the rapidity of change that causes the PMS.
No idea myself.
