SPECIAL LABORATORY METHODS

PICSI (preselected intracytoplasmic sperm injection)

PICSI is able to select the most suitable sperm cells from the sperm sample due to hyaluronan, which is a protein that binds only mature and healthy cells. The collected sperm cells are subsequently used for egg fertilization with ICSI. Success rate of fertilization is around 90%.

This procedure is used in the following cases:

  • high percentage of immotile sperm
  • previous failed fertilizations with ICSI
  • recurrent miscarriages and/or repeated embryo transfers without implantation
