IUI stands for intrauterine insemination. The troops are collected, washed, and inserted directly into the uterus via catheter.  Normally, only a few hundred troops make it to the uterus.  With IUI, that number can be in the upper millions.

IMG_4067 (1)We did three rounds of IUI early in 2016.  During each round I was prescribed Letrozole to stimulate follicle growth.  Interesting fact about Letrozole (aka Femara) – it is also used as a treatment for breast cancer.  It reduces the body’s estrogen production which, for some reason, causes the pituitary gland to release higher levels of FSH (follicle stimulating hormone). Then, 24-36 hours before the IUI, I was injected with hCG (human chorionic gonadotropin) to trigger the release of the egg(s) from the follicles. Hence the nickname “trigger shot.”
