In certain specific indications, a variant of microinjection (ICSI) may be used to optimize sperm selection. This technique involves choosing sperm under very high magnification microscopy (approximately 6,600×, compared to 400× in standard ICSI), allowing the exclusion of spermatozoa with specific morphological abnormalities.

This procedure, which is more time-consuming and technically demanding, is offered only in well-defined clinical situations where enhanced selection may improve outcomes.

Assisted hatching consists of thinning or weakening the zona pellucida—the protective membrane surrounding the embryo—in order to facilitate its hatching and potentially improve its chances of implantation.

This technique is offered only in specific situations, particularly when the embryonic membrane appears abnormally thick.

Extended culture consists of maintaining fertilized embryos in the laboratory in specialized media for up to six days, allowing them to develop to the blastocyst stage.

1. It facilitates the selection of embryos with the highest implantation potential.
2. It promotes better synchronization between embryonic development and the uterus.
3. Today, it represents the preferred approach in most fertility centers worldwide.

Embryo vitrification is an ultra-rapid freezing technique that preserves embryos under optimal conditions, without the formation of ice crystals.
It ensures excellent embryo survival upon warming.

This method allows embryos that are not transferred to be used at a later stage, according to the couple’s family plan and future reproductive goals.

This approach is intended for women who wish to postpone their plans for motherhood, particularly in situations where medical or genetic conditions may affect ovarian reserve.

After approximately ten days of hormonal stimulation, oocytes are retrieved under light sedation through ultrasound-guided aspiration. They are then vitrified in the laboratory using an ultra-rapid freezing technique, which involves immersing the oocytes in liquid nitrogen at –196 °C, ensuring optimal preservation of their cellular structure.

In most cases, normal daily activities can be resumed the day after the procedure.

The oocytes are safely stored within the center and may be used at a later time, whenever the patient decides to pursue pregnancy.
