What hormones change during the perimenopause (the menopausal transition)?

Your reproductive hormones are the main hormones changing their levels. These include estrogen and progesterone (from your ovaries), and luteinizing hormone (LH) and follicle stimulating hormone (FSH) from your hypothalamus located in your brain. During perimenopause, estrogen levels decrease overall, but might vary between very high or very low levels. These hormonal swings may account for mood disturbances (mood swings) and hot flashes.
