Embryology Lab in Lucknow & Kanpur

An embryology lab is a specialised, climate-controlled laboratory that forms the scientific core of every IVF and ICSI cycle. Inside the embryology lab, eggs and sperm are fertilised, embryos are cultured in CO₂ incubators, graded daily by clinical embryologists, and prepared for uterine transfer or cryopreservation. The quality of the embryology lab — its equipment, air purity, and the skill of its technicians — is the single most important determinant of IVF success rates. Javitri Hospital’s embryology lab is NABH-certified and fully equipped for all procedures including ICSI, blastocyst culture, vitrification, and PGT.

An embryology lab technician (clinical embryologist) is the specialist who performs all the hands-on laboratory work in IVF. This includes: processing retrieved eggs, preparing the sperm sample, performing ICSI (injecting a single sperm into each egg), daily embryo observation and grading, managing incubators and culture conditions, vitrifying (freezing) excess embryos and eggs, warming frozen embryos for transfer, and maintaining chain-of-custody documentation. At Javitri Hospital, our senior embryology lab technicians have extensive clinical experience and perform all procedures using advanced, calibrated embryology lab equipment.

Javitri Hospital’s embryology lab equipment includes: computerised ICSI micromanipulation systems, tri-gas CO₂ incubators with independent temperature and gas control, high-magnification inverted microscopes, VOC-filtered air purification systems (ISO Class 5), laminar airflow workstations, advanced vitrification (rapid-freeze) systems, liquid nitrogen cryostorage dewars with alarm systems, computer-assisted sperm analysis (CASA), and an electronic embryo witnessing system. All equipment is calibrated, serviced on schedule, and operated under NABH quality protocols.

The embryology lab is where fertilisation, embryo development, and selection happen — all outside the body. Even with excellent clinical stimulation and retrieval, poor lab conditions (temperature variation, CO₂ fluctuation, VOC contamination, or inadequate culture media) can halt embryo development entirely. Consequently, two clinics using the same stimulation protocol can have very different IVF outcomes purely because of lab quality. This is why choosing an IVF centre with a NABH-certified embryology lab and experienced embryology lab technicians is as important as choosing the right doctor.

Vitrification is a rapid-freeze cryopreservation technique used in the embryology lab to preserve embryos and eggs. By cooling cells so rapidly (approximately 20,000°C per minute), water within cells is converted to a glass-like state — preventing ice crystal formation that would otherwise damage cell structures. Vitrification achieves embryo and egg survival rates above 95% and has largely replaced slow-freezing. Yes, Javitri Hospital’s embryology lab offers vitrification for Day 3 embryos, Day 5 blastocysts, and eggs (oocyte cryopreservation for fertility preservation).

Blastocyst culture is the process of growing embryos in the embryology lab for 5–6 days (rather than the standard 2–3 days) until they reach the blastocyst stage — a more advanced developmental state with higher implantation potential. Not all embryos reach the blastocyst stage; consequently, blastocyst selection acts as a natural filter, identifying the strongest embryos. Javitri Hospital’s embryology lab uses tri-gas CO₂ incubators that maintain the precise conditions required for blastocyst development. Blastocyst culture is recommended based on the number and quality of embryos available.

Embryo grading is performed daily by the embryology lab technician (clinical embryologist) using high-magnification inverted microscopy. On Day 3, embryos are assessed for number of cells (ideal: 6–8), degree of fragmentation, and cell uniformity. On Day 5, blastocysts are graded for expansion (1–6), inner cell mass (ICM) quality (A/B/C), and trophectoderm (TE) quality (A/B/C). The highest-graded embryo is selected for transfer. All grading at Javitri Hospital follows established Gardner criteria and is documented with photographic records for every patient’s cycle.

Yes. Javitri Hospital’s embryology lab offers vitrification and long-term cryostorage for both embryos and eggs. Remaining good-quality embryos from an IVF cycle are vitrified and stored in liquid nitrogen dewars — available for frozen embryo transfer (FET) cycles in the future without repeating the full stimulation process. Similarly, eggs can be frozen for fertility preservation — for patients undergoing cancer treatment, or for those who wish to preserve their fertility for personal reasons. Our embryology lab maintains documented cryostorage records and safety systems for all stored gametes and embryos.

Javitri Hospital’s embryology lab combines everything that determines IVF success: NABH-certified quality systems, advanced embryology lab equipment (computerised ICSI, tri-gas incubators, vitrification systems, VOC-filtered air), senior embryology lab technicians with extensive hands-on experience, and 30+ years of clinical IVF expertise under Dr. Rajul Tyagi — trained at Cleveland Clinic USA and University Hospital Brussels Belgium. All processes are performed entirely in-house, with no outsourcing of any laboratory step. Furthermore, our patients receive daily embryo development updates — because transparency is part of our care standard.
