Understanding hormones

Hi wray great website
There is two things I don't understand why is it that when I am feeling estrogen dominant ie
Sore breasts I sleep better. When the breast tenderness goes away I can't sleep at all. I do use natpro 2 years now pg 5 years total but can't sleep when I use it late a night I am so confused
Also if progesterone was the hormone for libido why have men's sex drive always higher than females
As we have higher pg

Understanding hormones
by: Wray

Hi there It could be the sore breasts are nothing to do with oestrogen or progesterone, but a lack of iodine. But why iodine should fluctuate, and keep you awake is beyond me. Unless it's ramped up the thyroid! We do have two pages on breasts, something might give you a clue, see Breast Tenderness and Breast Cysts. And insomnia, as you probably know, can be helped by progesterone, see here, here and here. A lack of salt can keep us awake, see here. The amino acid tyrosine can help if the brain is in overdrive. Interestingly one study found insomnia is caused by hyperarousal, see here. But why any of these should fluctuate I don't understand. And as for libido, who says women's sex drive is less than men! We don't talk about it as much, or boast about our exploits, but the women I know have as good a libido as men. I have just done a page on libido, it was fascinating doing it, but it's not been put on the site yet. I've found it seems the main drive behind a good libido is the neurotransmitter dopamine. In fact one paper is entitled "Dopamine: helping males copulate for at least 200 million years"! And certainly not testosterone, which appears a minor player. Oestrogen doesn't feature in any of the studies. Incidentally we have many men using progesterone to increase theirs. We do have higher progesterone than men, but only in the luteal phase. During the follicular phase it's the same as men's. Take care Wray
