The testing looks at different genetic information depending on your needs.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>PGT-A<\/strong> checks the number of chromosomes in each embryo.<\/li>\n<\/ul>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>PGT-M<\/strong> looks for a known single-gene condition.<\/li>\n<\/ul>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>PGT-SR<\/strong> looks for changes in chromosome structure.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Your&nbsp;healthcare provider&nbsp;may recommend one or more tests based on your family history, genetic screening results, or past experiences.&nbsp;<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What is PGT-A?&nbsp;<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Preimplantation genetic testing for aneuploidy (PGT-A) looks at an embryo\u2019s chromosomes. Most people have 23 pairs of chromosomes, including sex chromosomes (XX, XY). An embryo with missing or extra chromosomes may have a lower chance of developing into a healthy pregnancy.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Why use PGT-A?<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Helps&nbsp;identify&nbsp;embryos with a normal number of chromosomes.&nbsp;<\/li>\n<\/ul>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Supports single-embryo transfer and reduces the chance of twins or triplets.&nbsp;<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">What is PGT-M?&nbsp;<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Preimplantation genetic testing for monogenic conditions (PGT-M) looks for a known single-gene condition. Each test is customized based on your specific gene change. A genetics lab studies a small cell sample from each embryo to learn whether the embryo is affected, a carrier, or unaffected.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Why use PGT-M?<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Your care team may recommend PGT-M if:&nbsp;<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>You, or your partner if applicable, have a single-gene condition that can be passed directly to a child. <br>This includes conditions where one gene change is enough to cause the condition (autosomal dominant) or conditions passed on through the X chromosome (X-linked).\u00a0<\/li>\n<\/ul>\n\n\n\n<ul class=\"wp-block-list\">\n<li>You, or your partner if applicable, both carry one copy of the same gene change.\u00a0<br>When both copies are passed on, the child may have the condition (autosomal recessive).\u00a0<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>How does PGT-M work?&nbsp;<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Testing begins before IVF starts.&nbsp;<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>You and the sperm source provide a DNA sample through blood or cheek swab.&nbsp;<\/li>\n<\/ul>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Sometimes, samples from affected family members are needed.&nbsp;<\/li>\n<\/ul>\n\n\n\n<ul class=\"wp-block-list\">\n<li>The genetics lab uses these samples to create a custom test. This step, called probe creation, usually takes 6 to 10 weeks.&nbsp;<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Once the probe is complete, you can move forward with IVF, and embryos can be tested using this customized approach.\u00a0<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What is PGT-SR?&nbsp;<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Preimplantation genetic testing for structural rearrangements (PGT-SR) looks for changes in chromosome structure, such as translocations or inversions.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Key points<\/strong>&nbsp;<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>These changes can be inherited or happen on their own.&nbsp;<\/li>\n\n\n\n<li>Balanced rearrangements are chromosome changes in which genetic material is rearranged but not missing or extra, meaning the carrier is typically healthy.\u00a0<\/li>\n<\/ul>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Most people with a balanced rearrangement are healthy and may not know they carry it.&nbsp;<\/li>\n<\/ul>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Carriers of balanced rearrangements have a higher chance of embryos with missing or extra genetic material.\u00a0<\/li>\n\n\n\n<li>Embryos with unbalanced rearrangements usually do not result in&nbsp;a live&nbsp;birth.&nbsp;This is because embryos with unbalanced rearrangements have missing or extra pieces of DNA.&nbsp;<\/li>\n<\/ul>\n\n\n\n<ul class=\"wp-block-list\">\n<li>About 5% of recurrent miscarriages are linked to structural rearrangements.&nbsp;<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">If your history suggests this may be a factor, your provider may order a blood test called a chromosome analysis (karyotype). Based on those results, PGT-SR may be recommended.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">How does PGT work during IVF?&nbsp;<\/h2>\n\n\n\n<ol class=\"wp-block-list\">\n<li>You complete your IVF cycle. When embryos reach the blastocyst stage (day 5 to 7), the embryologist removes a few cells from the outer layer of each embryo. These cells would form the placenta. <\/li>\n\n\n\n<li>The biopsy sample goes to a partner genetics lab for testing. The embryos stay frozen in the lab during this process.<\/li>\n\n\n\n<li>The lab studies the DNA to: \n<ul class=\"wp-block-list\">\n<li>Check&nbsp;chromosome&nbsp;number (PGT-A).&nbsp;<\/li>\n\n\n\n<li>Identify&nbsp;embryos not affected by a specific gene condition (PGT-M).<\/li>\n\n\n\n<li>Screen for&nbsp;a structural&nbsp;rearrangement (PGT-SR).<\/li>\n<\/ul>\n<\/li>\n<\/ol>\n\n\n\n<p class=\"wp-block-paragraph\">Because PGT-M looks at a single gene and PGT-A looks at chromosome number, both tests are often used together. Your&nbsp;provider&nbsp;and embryologist review your results along with embryo quality before choosing an embryo for transfer.&nbsp;<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What happens next?&nbsp;<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">If you have embryos available for transfer, you start a frozen embryo transfer cycle.&nbsp;<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>The embryologist selects the embryo based on PGT-A results and, if relevant, PGT-M or PGT-SR findings, plus embryo quality.<\/li>\n<\/ul>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Any remaining embryos stay frozen for future use or may be donated or discarded based on your consent.&nbsp;<\/li>\n<\/ul>\n\n\n\n<ul class=\"wp-block-list\">\n<li>About 2 weeks after the transfer, you take a pregnancy test to learn whether the embryo implanted.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">If you have questions, Progyny is here for you.
