Best;More compatible with the ovum sperm
The miscarriage rate is reduced
With PICSI (Physiological Intracytoplasmic Sperm Injection) the most mature, strongest and most fertile spermatozoa are chosen, as they are the most compatible with the egg.
In this way, sperm are selected individually and have low fragmentation rates, which reduces the possibility of genetic alterations.
This is one of the most novel techniques, since in contrast to traditional ICSI, in which sperm selection is carried out through observation by the embryologist, the PICSI technique is a less subjective system and sperm selection is carried out using a molecule similar to that of the natural oocyte.
When is this technique used?
Physiological Intracytoplasmic Sperm Injection or PICSI method is indicated for those couples in which the male has poor sperm quality, in couples who have suffered several repeated miscarriages, in couples with failed in vitro fertilization cycles and when the embryos are of poor quality.
How this technique is performed?
The sperm are placed on a dish with hyaluronic acid gel. The spermatozoa that have adhered to the gel will be the optimal ones and the embryologist will be able to select them easily. The motility and morphology are the characteristics that allow us to know which ones are better qualified.
