23 . A method of treating a human patient undergoing an embryo transfer procedure, wherein the embryo transfer procedure comprises in vitro fertilization, thereby producing one or more embryos, followed by transfer of the one or more embryos to the uterus of the patient, the method comprising administering to the patient a pharmaceutical composition comprising (i) a compound of formula (3Z,5S)-5-(hydroxymethyl)-1-[(2′-methyl-1,1′-biphenyl-4-yl)carbonyl]pyrrolidin-3-one O-methyloxime and (ii) one or more pharmaceutically acceptable carriers, diluents, or excipients, wherein the purity of the compound relative to one or more other stereoisomers of the compound is at least 85%.
24 . The method of claim 23 , wherein the purity of the compound relative to one or more other stereoisomers of the compound is at least 90%.
25 . The method of claim 24 , wherein the purity of the compound relative to one or more other stereoisomers of the compound is at least 95%.
26 . The method of claim 23 , wherein the purity of the compound relative to one or more other stereoisomers of the compound is from about 90% to about 99.9%.
27 . The method of claim 26 , wherein the purity of the compound relative to one or more other stereoisomers of the compound is from about 95% to about 99.9%.
28 . A method of treating a human patient undergoing an embryo transfer procedure, wherein the embryo transfer procedure comprises in vitro fertilization, thereby producing one or more embryos, followed by transfer of the one or more embryos to the uterus of the patient, the method comprising administering to the patient a pharmaceutical composition comprising (i) a compound of formula (3Z,5S)-5-(hydroxymethyl)-1-[(2′-methyl-1,1′-biphenyl-4-yl)carbonyl]pyrrolidin-3-one O-methyloxime and (ii) one or more pharmaceutically acceptable carriers, diluents, or excipients, wherein the purity of the compound relative to its stereoisomer, (3E,5S)-5-(hydroxymethyl)-1-[(2′-methyl-1,1′-biphenyl-4-yl)carbonyl]pyrrolidin-3-one O-methyloxime, is at least 85%.
29 . The method of claim 28 , wherein the purity of the compound relative to (3E,5S)-5-(hydroxymethyl)-1-[(2′-methyl-1,1′-biphenyl-4-yl)carbonyl]pyrrolidin-3-one O-methyloxime is at least 90%.
30 . The method of claim 29 , wherein the purity of the compound relative to (3E,5S) (hydroxymethyl)-1-[(2′-methyl-1,1′-biphenyl-4-yl)carbonyl]pyrrolidin-3-one O-methyloxime is at least 95%.
31 . The method of claim 28 , wherein the purity of the compound relative to (3E,5S) (hydroxymethyl)-1-[(2′-methyl-1,1′-biphenyl-4-yl)carbonyl]pyrrolidin-3-one O-methyloxime is from about 90% to about 99.9%.
32 . The method of claim 31 , wherein the purity of the compound relative to (3E,5S)-5-(hydroxymethyl)-1-[(2′-methyl-1,1′-biphenyl-4-yl)carbonyl]pyrrolidin-3-one O-methyloxime is from about 95% to about 99.9%.
