    Abstract: The present inventive concept is related to a modified follicle-stimulating hormone (FSH), in particular, a hypo-glycosylated form of FSH, as well as compositions and formulations including, nucleic acids encoding, cell lines expressing, and methods of using the hypo-glycosylated FSH as disclosed herein. These methods of use include methods of treating infertility, methods of inducing follicle growth and/or maturation, methods of inducing oocyte/egg growth and/or maturation, methods of stimulating sex steroid secretion, methods of treating or preventing bone density loss, and methods of treating or preventing fatty tissue accumulation.

    Abstract: Two long-acting recombinant porcine FSH (follicle-stimulating hormone) fusion proteins, comprising pFSH-Fc-1 and pFSH-Fc-2. α subunit/β subunit is directly or indirectly fused on a Fc fragment by means of a linking component; the β subunit/α subunit is combined with the α subunit/β subunit by means of a Van der Waals force or the linking component. The porcine FSH fusion proteins can be prepared by an eukaryotic expression system based on a gene engineering technology. The two porcine FSH fusion proteins have a good medicinal effect and have a longer half-life period as compared with that of a natural porcine FSH; the two porcine FSH fusion proteins do not generate an undesirable effect on animals and can replace pregnant mare serum gonadotropin (PMSG) to be used in animal breeding production. The two porcine FSH fusion proteins can be used for preparation of medicines in the field of animal breeding.
