progesterone

source - ovaries

ADH (antidiuretic hormone)

source - pituitary gland

effect - controls water reabsorption in kidneys —> more ADH = more water reabsorption

LH (luteinising hormone)

source - pituitary gland

effect - triggers ovulation and progesterone production

FSH (follicle-stimulating hormone)
