HUMAN REPRODUCTION LABORATORY
The laboratory is where parenthood begins. For individuals and couples facing infertility, the quality of the embryology laboratory behind their treatment is one of the most consequential factors in determining success. From the moment eggs are retrieved to the moment embryos are ready for transfer, every procedure depends on the precision, technology, and scientific rigor of the team and facility responsible for their care.
At Chedid Grieco, our human reproduction laboratory in São Paulo, Brazil, operates at the highest level of international reproductive medicine standards. Led by Dr. Silvana Chedid, Head of the Brazilian Technique and a reproductive medicine pioneer with nearly 30 years of clinical experience, our laboratory has supported over 8,780 successful births. We are proud to hold both FDA and New York Department of Health (NYDH) licensing, making us one of only eight facilities outside the United States to carry a New York tissue license. Every cycle performed in our lab reflects our commitment to boutique, individualized care, rigorous quality standards, and the science that makes parenthood possible. Patients can explore our full range of fertility treatments to understand how our laboratory supports each step of their care.
What Happens Inside a Human Reproduction Laboratory
A reproductive medicine laboratory is a highly controlled, specialized environment designed to support the development of human eggs, sperm, and embryos outside the body. According to the American Society for Reproductive Medicine, embryology laboratories must meet strict standards for air quality, temperature control, equipment calibration, staffing, and accreditation to ensure the safety and effectiveness of every assisted reproductive technology procedure.
Inside our São Paulo laboratory, embryologists work under conditions that closely replicate the natural environment of the human body. Incubators maintain precise gas concentrations, humidity, and temperature. Every oocyte retrieval, fertilization, embryo culture, and cryopreservation step is performed following validated protocols, documented quality control, and a double-witness identification system that ensures the integrity of each patient’s specimens at every stage of care. This level of precision is what separates an exceptional reproductive laboratory from an average one.
Laboratory Services and Technologies We Offer
Our laboratory is equipped to support the full spectrum of assisted reproductive technology procedures. Each service is performed by trained embryologists under the oversight of our laboratory director, and all protocols are reviewed and updated regularly to reflect advances in reproductive science. The procedures available through our laboratory include:
- In vitro fertilization (IVF): fertilization of eggs and sperm outside the body, with embryo culture and transfer to achieve pregnancy
- Intracytoplasmic sperm injection (ICSI): a single sperm is injected directly into a mature egg to facilitate fertilization when male factor infertility is present
- Preimplantation genetic diagnosis (PGD): genetic screening of embryos before transfer to reduce the risk of inherited conditions and chromosomal abnormalities
- In vitro maturation (IVM): immature eggs are matured in the laboratory rather than inside the body, eliminating or greatly reducing the need for ovarian stimulation injections
- Blastocyst culture: embryos are cultured to the advanced blastocyst stage, allowing our embryologists to select the strongest candidates for transfer
- Oocyte and embryo cryopreservation: vitrification technology preserves eggs and embryos for future use, supporting fertility preservation and staged treatment cycles
- Assisted hatching: a precise opening is made in the embryo’s outer shell to support implantation in select patients
Each of these procedures is available as part of a personalized treatment plan developed in collaboration with your physician. Our team works to match the right laboratory approach to each patient’s clinical situation, ensuring that the technology used reflects your individual needs rather than a one-size-fits-all protocol.
Why Laboratory Standards Matter for Your Outcome
Not all fertility laboratories operate at the same level of accreditation, staffing, or technical capability. The standards governing reproductive medicine laboratories require ongoing quality management, proficiency testing, and compliance with accrediting bodies including the FDA and state health departments. Our laboratory holds both FDA licensure and NYDH certification, which requires compliance with some of the most stringent reproductive tissue standards in the world. These credentials are not routine — they reflect a sustained commitment to safety, documentation, and laboratory excellence that benefits every patient in our care.
Our team performs more than 1,200 cycles per year in our São Paulo facility, a volume that supports a high level of embryological skill and consistency across procedures. Our laboratory is also equipped to support advanced techniques including preimplantation genetic diagnosis and in vitro maturation, both of which require specialized equipment, training, and protocol development beyond standard IVF. Patients can review our full licensing and professional credentials on our licenses and associations page.
A Laboratory Built for International Patients
Many of our patients travel from the United States and other countries to access care in our São Paulo laboratory. Our team speaks Spanish, Portuguese, French, and English, and we are structured to support international patients at every stage, from initial consultation to laboratory procedures to post-transfer follow-up. Our clinic is proud to be LGBTQI+ friendly and welcomes individuals and couples of all backgrounds on their path to parenthood.
Consultations are held in Miami, Florida, giving patients the opportunity to meet with our team, develop a personalized care plan, and ask questions about laboratory procedures close to home. All treatment and laboratory work then takes place at our accredited facility in Brazil, where patients benefit from world-class reproductive medicine at a fraction of the cost of comparable treatment in the United States.
