TTC, IVF, WTF: The Infertility Dictionary

There’s no shortage of things to stress over when you’re going through infertility; but add a bunch of random acronyms into the mix and stuff gets a lot more confusing. This post explores some popular phrases, abbreviations and slang in the fertility lexicon.

Staring down the long road of infertility is massively intimidating for many reasons. First of all, there’s the whole you-have-no-control-over-your-life-and-everything-you-thought-you’d-have-and-would-come-easily-is-nowhere-to-be-found thing. Second of all, there’s basic TTC (Trying to Conceive) vocabulary.

“Infertility” is it’s own language and getting fluent can take a while. I’ve been TTC for 3 years and I still am in the dark with some phrases or medical terms. Aside from there being an intense amount of biological and physiological information that is assumed knowledge by your OBGYN and your RE, there are SO. MANY. ACRONYMS. And unless you’re a compulsive oversharerer on Twitter, Instagram or Tumblr, chances are you don’t know your OPK from your DPO. And that? That’s a problem when trying to decipher the Infertility Code (a much more complicated puzzle to solve than the Da Vinci Code). Understanding the different tests, hormones, dates, and procedures is essential to understanding your body as well as your medical options.

So study up, young grasshopper. Below are the essentials for starting your fertility journey. If you are noticing a glaring omission, please add yours in the comments below.
