Fertility Language by Dr Kirsten Wolfe

Fertility has a whole language of its own which can be daunting when you’re starting your fertility journey or beginning IVF.  There are many abbreviations and acronyms, I liken it to understanding my teenagers texts to me, I often find myself googling what they hell they mean!  It can feel like some secret club that you don’t yet belong to, but don’t worry before long it will feel totally natural. Much like learning to ride a bike.


Here’s an alphabetical list of the most commonly use terms to help you navigate when talking on forums or to help when talking to other friends that are also going through infertility.
