After egg retrieval, our embryologists care for your eggs and embryos through fertilization, embryo development, genetic testing when appropriate, cryopreservation, and preparation for transfer.
At Spring Fertility, our laboratories combine exceptional embryologists, advanced engineering, carefully controlled environments, rigorous safeguards, and continuous scientific improvement, all designed around one responsibility: providing extraordinary care for the eggs and embryos entrusted to us.
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.
Discover the thinking, science, and specialized laboratory environment behind Spring’s uncommon approach to egg and embryo care.
Your physician guides your treatment, performs your retrieval, and transfers your embryo. Between those moments, much of your IVF journey belongs to the laboratory.
This is where eggs are identified and assessed, sperm is prepared, fertilization occurs, embryos develop, biopsies may be performed, and eggs and embryos are cryopreserved.
These are some of the most delicate stages of IVF. Eggs and embryos are sensitive to their surroundings, which is why laboratory quality depends on far more than an incubator or microscope.
It requires experienced people, carefully controlled environments, sophisticated engineering, rigorous processes, and attention to details patients may never see.
At Spring, those details matter.
Experienced embryologists bring scientific expertise, precision, and judgment to every stage of laboratory care.
Purpose-built systems help maintain carefully controlled conditions around eggs and embryos throughout critical laboratory procedures.
Layered identification, monitoring, quality systems, and standardized protocols support consistency and confidence throughout laboratory care.
After retrieval, your eggs begin a carefully orchestrated journey through the embryology laboratory.
Depending on your treatment plan, Spring’s embryologists may:
Behind each of these steps are laboratory systems designed to support precision, consistency, and careful control.

We initially found Spring by following our embryologist. They left our first clinic because Spring had built the lab of their dreams. If the person we trusted most in the lab believed in Spring enough to make that move, we knew we should too.

Spring Fertility operates CAP-accredited IVF laboratories. Accreditation by the College of American Pathologists provides independent evaluation of laboratory quality, safety, personnel competency, equipment, documentation, and quality systems.
For patients, it provides another layer of confidence in the standards behind their laboratory care.
Accreditation is a standard—not a finish line. Our teams continually evaluate laboratory performance, environmental conditions, equipment, protocols, emerging science, and new technologies.
Quality isn’t something we prepare for when an inspection is coming. It’s built into how our laboratories operate every day.
