Intrauterine insemination (IUI) is a fertility treatment that involves placing sperm directly into a woman's uterus during her ovulation period. This procedure increases the chances of sperm reaching the egg, as it bypasses the cervix and allows for a more direct approach. IUI is often used for couples facing infertility issues or for single women and same-sex couples seeking to conceive. The process typically involves monitoring the woman's ovulation cycle, which can be done through blood tests or ultrasound. Once the optimal time is identified, a healthcare provider will insert a thin catheter containing prepared sperm into the uterus. IUI is generally considered a less invasive and more affordable option compared to other fertility treatments like in vitro fertilization (IVF).
