State-of-the-Art Facilities

Our modern facilities feature state-of-the-art technology that uses embryoscope-assisted IVF, an advanced form of time-lapse imaging to monitor the development of embryos. It allows our fertility specialists to observe embryos continuously throughout their development while minimizing the disturbance to the embryos.

Our IVF laboratory provides:

Optimized Embryo Selection:

By monitoring embryo development in real-time, we identify which embryos have the best chance of implanting successfully. The technology helps in selecting the most viable embryos for transfer based on factors like cell division, symmetry, and developmental milestones.

Non-Invasive Monitoring:

Our non-invasive monitoring process minimizes any disturbance to the embryo.

Improved Success Rates:

GFG’s embryoscope-assisted IVF process helps improve implantation rates and increases pregnancy success rates.
