Sudden infant death syndrome and progesterone.
Some victims of sudden infant death syndrome have evidence of chronically defective ventilation as do some members of the victims family and the subsequent siblings. Furthermore, the death seems to occur when the proportion of more vulnerable non-rapid eye movement sleep is increasing and serum progesterone is low. Both endogenous and exogenous progesterone are effective respiratory stimulants. The relationship of these three features does not appear to have been studied.
