What is CAPA-IVF?

  • CAPA-IVF* is a disruptive new fertility technology.
  • CAPA-IVF enables a more natural way of obtaining mature oocytes for IVF and social freezing without the burden and risks of systemic ovarian stimulation.
  • CAPA-IVF aims to provide an alternative safe and effective option for infertile couples, and when seeking oocytes and embryo preservation for future fertility.
