FIELD: chemistry.
SUBSTANCE: description is given of thiomorpholine derivatives of steroids with general formula I 
. These steroids are characterised by presence of a thiomorpholine fragment, bonded to a C17 steroid skeleton through an alkylene spacer, where R4 and R4' are hydrogen and methyl, under the condition that, both R4 and R4' represent hydrogen at the same time.
EFFECT: invention can be successfully used for stimulating meiosis of human oocyte.
