Disclosed are methods for increasing the fertilization rate of an oocyte in a granulosa cell-oocyte complex, and/or the success rate of in-vitro fertilization by using mitochondrial therapies. Also disclosed are methods of identifying compounds for fertility treatment.

Disclosed herein is a method for treating an osteoarthritis in a subject in need thereof. The method mainly includes administering to the subject an effective amount of isolated mitochondria. According to some embodiments of the present disclosure, the isolated mitochondria are administered to the subject in need in the amount of about 1 mg/kg to about 100 mg/kg.

Single nucleotide polymorphic sites of the bovine MAP1B, PPP1R11, and DDX4 genes are associated with improved bull fertility as measured by e.g. sire conception rates. Nucleic acid molecules, arrays, kits, methods of genotyping and marker-assisted bovine breeding methods based on these SNPs are disclosed.

Provided herein are immunomodulatory proteins comprising ICOSL variants and nucleic acids encoding such proteins. The immunomodulatory proteins provide therapeutic utility for a variety of immunological and oncological conditions. Compositions and methods for making and using such proteins are provided.

Methods are described for differentiating stem and post-natal cells into sex hormone-producing cells that can be administered to a patient autologously or allogeneically in order to maintain in balance, or rebalance, their hypothalamic-pituitary-gonadal (HPG) axis.

Non-hormonal contraception compositions and methods for contraception are provided. One embodiment provides an antibody or an antigen binding fragment thereof that specifically binds to one or more sperm antigens and inhibits the ability of anti-body-bound sperm to fertilize an egg. Typically, the antibody is a monoclonal antibody, for example a human or humanized monoclonal antibody. In one embodiment, the antibody or antigen binding fragment thereof specifically binds to CD52g expressed on vertebrate, for example human, sperm cells and inhibits, blocks, or reduces the ability of the antibody-bound sperm to fertilize an egg. In one embodiment the antibody contains a membrane anchor. The membrane anchor can contain transmembrane domains, glycosylphosphatidylinositol anchors, or myristoylation motifs.
