👉 The gb fluid, or gonadal-bovine fluid, is a colloidal suspension of cells derived from the testes and ovaries of cattle, used in medical research to study human reproductive biology and diseases. It's composed of a complex mixture of cells, including spermatogonia, spermatocytes, and various other cell types, suspended in a protein-rich matrix. This fluid mimics aspects of human seminal plasma and has been instrumental in understanding male fertility, spermatogenesis, and the effects of various treatments on reproductive health. Researchers use it to investigate conditions like male infertility, test the efficacy of drugs, and develop new therapies for reproductive disorders.
