Dr Tween can undertake pre-implantation genetic diagnosis (PGD) and pre-implantation genetic screening (PGS) to test embryos for genetic conditions and undertake chromosomal screening, identifying the most appropriate ones to transfer.

Couples who have a family history of a genetic condition may choose to avoid passing the condition onto their offspring. PGD can be used to identify the embryos without the genetic condition, before transferring them back to the woman’s womb. PGS is the technology to biopsy and test embryos for chromosomal abnormality. By transferring the normal, tested embryo, you have an improved chance of a successful pregnancy.
