Egg Fertilization

The choice of fertilization method at Gynatal is never random; it is based on a deep analysis of the spermogram and patient history to minimize cognitive friction and maximize success. 

Conventional IVF (Standard Fertilization) 

This method mimics natural fertilization. Oocytes are placed in a culture medium with a precisely defined concentration of sperm, where the most vital sperm cell penetrates the egg on its own. This is recommended for cases with optimal semen parameters. 

ICSI (Intracytoplasmic Sperm Injection) 

ICSI is a microsurgical procedure where an embryologist uses a micromanipulator to inject a single, selected sperm cell directly into the cytoplasm of a mature egg. This method is the "Scientific Gold Standard" for overcoming male factor infertility or previous fertilization failures. 

For patients requiring a higher tier of care, such as those with Recurrent Implantation Failure (RIF), we deploy techniques that go beyond standard ICSI: 

• IMSI (6000x Magnification): Allows embryologists to examine the internal structure of the sperm head at extreme magnification to exclude cells with morphological defects. 
• PICSI (Physiological ICSI): Utilizes hyaluronan to select only mature and genetically stable sperm, mimicking the natural selection process within the female reproductive tract. 
• Rescue ICSI: A unique emergency procedure where eggs that failed to fertilize spontaneously during conventional IVF can be fertilized 18–24 hours later, potentially "saving" the treatment cycle.
