When medical conditions prevent a woman from carrying a pregnancy to term, In Vitro Fertilization (IVF) combined with gestational surrogacy offers a highly successful path to biological parenthood. Understanding when this procedure is recommended, its distinct medical features, and how egg donors are integrated is essential for planning your journey.

When is IVF with Surrogacy Recommended?

Medical indications for this program are strictly regulated by reproductive medicine guidelines. The main indications include:

• Absence or Structural Anomalies of the Uterus: Congenital absence (MRKH syndrome) or surgical removal of the uterus due to medical necessity.

• Repeated IVF Failures: Multiple unsuccessful embryo transfers (usually 3 or more) despite high-quality embryos and a structurally healthy uterus.

• Recurrent Pregnancy Loss: A history of repeated miscarriages that cannot be medically resolved.

• Severe Systemic Diseases: Conditions affecting the heart, kidneys, or oncology status where pregnancy poses a direct threat to the intended mother's life.

Key Medical Features of the Process

IVF in a surrogacy framework differs fundamentally from standard fertility treatments due to several critical features:

• Complete Genetic Separation: Gestational surrogacy guarantees that the surrogate shares 0% DNA with the child. The baby belongs genetically to the intended parents, or to the parents and a chosen donor.

• Synchronization of Cycles: If fresh embryos are used, the menstrual cycles of the intended mother (or egg donor) and the surrogate mother must be precisely aligned using custom hormonal protocols.

• Cryopreservation Advantage: In modern IVF, freezing embryos via vitrification is highly preferred. This allows the embryos to be genetically tested (PGT-A) and transferred during the surrogate’s natural, optimal "implantation window" without time pressure.
