A substantially pure steroidogenesis inducing protein ("SIP") is disclosed. The protein is characterized by a molecular weight of 60 kd as determined by SDS-PAGE, a pI of 4.7 to 4.9 and a non cAMP linked mechanism of action. The protein stimulates production of sex and adrenal cells, and also stimulates the production of various steroid hormones. The use of the pure protein in various therapeutic contexts as well as pharmaceutical compositions for therapy are also disclosed.
