The invention relates to the chemistry of peptides, pharmacology and medicine, and specifically to a new group of peptides having the property of stimulating sexual and genital function and having increased storage stability. For this purpose, peptides of general formula (I) are proposed: A-Thr-Lys-Hyp-B-C-D-X, (SEQ ID NO: 8), in which A is 0, Met, Met(0), Thr, Ala, His, Phe, Lys, Gly; B is 0, Gly, Asp, Trp, Gln, Asn, Tyr, Hyp, Arg; C is 0, Arg, Phe, Tyr, Gly, His, Hyp, Lys; D is 0, Val, Gly, Tyr, Trp, Phe, His; X is OH, OCH3, NH2; where 0 is the absence of an amino acid residue, provided that if A≠0, then B and/or C and/or D≠0, if B≠0, then C and/or D≠0, excluding the tetrapeptides, as well as the peptides Phe-Thr-Lys-Hyp-Gly, (SEQ ID NO: 9), Thr-Lys-Hyp-Hyp-Arg (SEQ ID NO: 10) and Thr-Lys-Hyp-Arg-Gly (SEQ ID NO: 11). The invention also relates to pharmaceutical compositions containing the indicated peptides, as well as to the use of the above indicated compositions for the treatment of women with severely decreased libido or with totally absent libido, orgasmic dysfunction, sexual dysfunction not caused by organic disorders or diseases, HSDD, FSAD or FSIAD, and to a method of treating and/or preventing female sexual dysfunction.
