This product is a specialized egg retrieval solution designed for follicular lavage and oocyte collection in assisted reproductive technologies. Its core utilizes a HEPES buffering system to ensure sustained pH stability during operations outside incubators. Simultaneously, it incorporates an enhanced HTF medium formulation to provide nutritional support for oocytes that closely mimics the physiological environment of the human fallopian tube. The formulation scientifically incorporates specific chelating agents to reduce potential cellular toxicity from heavy metal ions in the medium. It also integrates antioxidant components to effectively neutralize free radicals, establishing a defense against oxidative stress. This product employs a protein-free formulation to eliminate bubble formation during washing at its source. It omits pre-added heparin to streamline laboratory procedures while preserving flexibility for on-demand addition. Furthermore, it contains non-essential amino acids, collectively establishing a safe, stable, and controllable in vitro platform for oocyte retrieval and initial viability.
