Preimplantation genetic testing improves embryo selection by identifying chromosomal abnormalities before transfer. This detailed screening process helps lower overall miscarriage risks. Specialists biopsy blastocysts, which are five-day embryos, to select healthy embryos for transfer. This targeted selection increases pregnancy chances for each transfer. Overall success still depends on individual egg quality and uterine health.

PGT-A screens embryos for incorrect chromosome numbers, a condition called aneuploidy. PGT-M tests for specific single-gene inherited disorders, such as cystic fibrosis. Specialists perform trophectoderm biopsy, which removes a few cells from outer embryo walls. Both methods help fertility specialists select unaffected embryos before carrying out transfer. Testing requires close collaboration with certified medical genetics laboratories.

Embryo biopsy carries a very small risk, but skilled embryologists minimize potential damage. Biopsies occur at the blastocyst stage, removing cells only from the outer layer. This outer layer eventually forms the placenta rather than the baby itself. Embryos undergo freezing while genetic analysis occurs in a specialized testing lab. Frozen embryo transfers allow the uterus time to prepare for optimal implantation.

Genetic testing results typically arrive within two to three weeks after embryo biopsy. During this waiting period, embryos remain safely preserved through vitrification, a rapid freezing process. Once genetic reports confirm healthy embryos, your care team schedules the frozen embryo transfer. Pre-travel planning helps international patients coordinate treatment timelines effectively.

PGT expenses depend on the number of embryos biopsied and the specific genetic testing type. PGT-M for single-gene conditions involves custom probe creation, which increases initial laboratory costs. Additional expenses include embryo vitrification, storage fees, and frozen embryo transfer procedures. Patients should request itemised estimates covering both clinical care and lab fees.

PGT-SR detects structural chromosome rearrangements, such as translocations, in developing embryos. Parents carrying balanced chromosomal shifts often face recurrent pregnancy loss or fertility challenges. Testing ensures only embryos with normal chromosomal structure are selected for transfer. This targeted approach reduces miscarriage risks associated with parental chromosomal variations. Fertility specialists work alongside genetic counselors to explain detailed results.

PGT significantly reduces specific genetic risks, but medical procedures cannot guarantee outcomes. Testing screens for targeted chromosomal or genetic conditions rather than every health issue. Routine prenatal care and standard pregnancy monitoring remain necessary throughout pregnancy. Specialists discuss test accuracy and diagnostic limits during preliminary medical consultations. Understanding these limitations helps patients make informed fertility decisions.

PGT can be performed on any number of viable blastocysts created during IVF. Having multiple embryos increases the chances of identifying genetically normal candidates for transfer. Specialists evaluate maternal age and ovarian response when planning stimulation protocols. Your medical team provides realistic expectations based on initial diagnostic findings. Laboratory standards determine how many embryos safely reach the biopsy stage.
