Few IVF labs in the U.S. maintain a controlled physiologic environment while eggs and embryos are being actively handled outside the incubator. Spring does. Our specialized enclosed workstations maintain carefully controlled temperature, gas, and atmospheric conditions during critical procedures such as egg handling, fertilization, and embryo biopsy. When eggs and embryos are at their most vulnerable, we take extraordinary care to maintain an environment designed around their physiologic needs.
Experienced embryologists bring scientific expertise, technical precision and careful judgment to every stage of fertilization and embryo development. Technology matters, but the expertise of the people using it remains fundamental to laboratory quality.
Purpose-built air filtration, environmental controls and specialized laboratory systems help maintain the clean, stable conditions required for sophisticated embryology. Our laboratories are engineered around the needs of reproductive cells and the embryologists caring for them.
RFID electronic witnessing continuously matches your eggs, sperm and embryos to you throughout critical laboratory steps, while independent manual verification provides an additional human check. Together, these systems create multiple layers of identification and security, maintaining a clear chain of custody and giving you confidence that your eggs, sperm and embryos remain unmistakably yours.
Your frozen eggs and embryos are under constant watch. Multiple layers of continuous monitoring provide constant vigilance over cryostorage conditions, backed by system redundancies, proactive checks, immediate alerts, and rigorous human and technological oversight.
Our laboratory teams continually evaluate performance, emerging science, technologies, protocols and quality systems. That means questioning even small details of how eggs and embryos are handled and looking for opportunities to make an already highly controlled process even better.
