TTC, assisted reproduction and Infertility Acronyms

Why are there infertility and IVF acronyms?

Like any industry infertility, trying to conceive and assisted reproduction have created their own language of sorts to make communicating quicker. These are used in both communities, hobbyists and professional circles. They are predominantly used in written word but are becoming more and more popular in speech and face to face conversation.

Hence if you are just starting out on your fertility journey then you understand what these acronyms mean. When we use an acronym in an article we always try to define it on the first use, but like anyone we sometimes miss this because we are so comfortable with using them. So if you spot any on the website that you are unfamiliar with then please let us know so that we can amend it.

Infertility, trying to get pregnant and IVF all have their own language but with a lot of cross over.

I remember when I showed Nathan a post from one of my infertility supports groups he was having to ask me every few words what on earth something meant. He has since become an expert. They often read something like this.

My DH and I have been TTC for 14 cycles before being referred for IUI, unfortunately my I have LPD and this leads to AF coming at any time. Sadly IUI didn’t work for us, however on our first IVF cycle we got a beautiful 5AA Blasty and a BFP on 8dp5dt!
