IUI (intrauterine insemination)
A fertility treatment in which prepared sperm is placed directly into the uterus around the time of ovulation.
In plain English
It's a simpler treatment than IVF, where washed sperm is placed directly into your womb around when you're ovulating.
Why it matters
It's less invasive and cheaper than IVF but has lower success rates per cycle, so it's usually suggested for specific situations rather than unexplained or severe infertility.
