Who is a good candidate for this procedure, and are there any contraindications?

Good candidates include women or couples with a history of two or more unexplained miscarriages, recurrent implantation failure, or known chromosomal abnormalities in prior pregnancies. Women over 35 or those with diminished ovarian reserve may also benefit. Contraindications include severe untreated medical conditions (e.g., uncontrolled diabetes or hypertension), active infections, or uterine abnormalities not amenable to correction. A thorough pre-treatment consultation with a reproductive specialist is required to confirm suitability.
