Understanding Surrogacy Jargon Part 2
Previously we listed some terms that you’re likely to see before and leading up to transfer. The vocabulary of third party reproduction doesn’t stop at transfer though. With each new phase there are new keywords and shorthand abbreviations as well. Here’s a list of new terms that you may start to hear once the embryo has been transferred.
AZH: Assisted Hatching. This is a procedure wherein a fertilized egg can have a small opening created on it to help encourage the egg to implant in the uterus. This is especially helpful in women older than 37 years, in frozen embryo transfers or in cases where the shell surrounding the embryo may be thick or harder than normal.
2WW– The Two Week Wait. This is the amount of time between when the embryo is transferring into the uterus and when the first blood test (beta) will determine whether or not pregnancy was achieved.
5dp5dt– This combination of letters and numbers represents how far along your surrogate is in her transfer. Translated this means, “5 Days Past 5 Day Transfer.”
Beta– The blood test done to confirm pregnancy. This test is completed several days following the transfer.
hCG, HCG: Human Chorionic Gonadotropin. Commonly referred to as the “Pregnancy Hormone,” hCG is required to produce a mature egg, stimulate the release of that egg during ovulation, and remains present during pregnancy. It is this hormone that causes a pregnancy test to read positive.
EDD: Estimated Due Date. This one is pretty simple. It’s the date we expect a baby to be born.
PIO: Progesterone in Oil. This is a form of injectable medicine delivered into the muscle, typically of the upper outer buttocks quadrant. The hormone progesterone is needed to maintain the pregnancy in the early weeks. The patient will be slowly weaned off of this medicine around the start of the second trimester.
GTT: Glucose Tolerance Test. This is a test used to screen for diabetic tendencies. In most pregnancies the test is done at the start of the third trimester as a precaution to screen for gestational diabetes.
