Preimplantation Genetic Screening (PGS), in conjunction with IVF, can be life changing for someone with recurrent miscarriage, someone who is older or whose ovaries do not work as well as expected, or someone with multiple failed fertility treatments.
In Vitro Fertilization
The basics of IVF include stimulating the ovaries to produce multiple eggs, retrieving them, then fertilizing them in our embryology laboratory. Before transferring one or more of the resultant embryos into the womb, they can be tested for chromosomal abnormalities as well as gender selection.
Screening for Chromosomal Abnormalities
All men and women have some eggs or sperm that are chromosomally abnormal. PGS tests for these chromosomal abnormalities in embryos, specifically looking for too many or too few chromosomes.
Chromosomal numerical abnormalities may lead to spontaneous miscarriage, failure to implant, birth defects, mental retardation, health problems, or disorders such as Down Syndrome.
Screening for Gender Selection
PGS can also test for sex selection. This involved performing a biopsy on Day 5 of embryo development in our laboratory to discover gender and determine which embryo(s) will be placed back into the uterus where it hopefully will implant and grow into a healthy bouncing baby girl or boy.
