A YouTube talk by Dr. Tabatha Barber about hormonal changes in perimenopause for people over 40. The speaker explains that ovaries can continue producing estrogen even when not ovulating or producing progesterone, which can lead to temporary low-estrogen periods followed by estrogen 'spikes' and changing need for estrogen replacement.
I don't want you to be frustrated if you're north of 40 and you feel like you're working with a provider. You maybe even got an estrogen replacement because your estrogen was low for a little while and then you find you no longer need it. That is because your ovaries are still trying to produce estrogen even though they're not ovulating, they're not producing progesterone, they're not doing all those pieces. They're still trying to squeeze out the last bit of estrogen and function they possibly can. And sometimes that looks like estrogen spikes.
