I've been around these IF boards for sometime now and I still don't know all the IF related abbreviations. Maybe it's because of my bad memory.

Anyway, I think it might be good to make a list of all the IF abbreviations that you've seen or used.

(I googled this list.)

IVF: In vitro fertilization
IUI: Intra-uterine Insemination
HSG: Hysterosalpingogram
HCG: human Chorionic Gonadotropin AKA trigger shot to induce ovulation

ISCI: Intra-cytoplasmic sperm injection
ART: Assisted Reproductive Technology
ER: Egg Retrieval
ET: Embryo Transfer
FET: Frozen Embryo Transfer

AMH: Anti-Mullerian hormone
SA: Sperm Analysis
SMEP: sperm meets egg plan
PIO: progesterone in oil

B/w: blood work
PGD: Preimplantation genetic diagnosis
WTF appt: It's the appointment where you ask your doctor why the hell all the drugs, perfect timing, IUI, IVF, you name it!, hasn't worked!
CD: cycle day (CD1 is the first day of your period)
MFI: male factor infertility
RE: reproductive endocrinologist

Any others?
