Be in the Know. Intrauterine Insemination at a Glance.
Intrauterine insemination, often called IUI, is an office-based fertility treatment that inserts sperm directly into the uterus around the time of ovulation. IUI assists sperm in traveling to the egg for fertilization by placing it high in the uterine cavity, past the vagina and cervix. IUI is often the first treatment individuals and couples receive for infertility due to its ease, affordability, and efficacy in treating several causes of infertility, including unexplained infertility, mild-to-moderate male factor infertility, mild endometriosis, and anovulation (the absence of ovulation) as well as for women wishing to use donor sperm to conceive. Reproductive endocrinologists can perform IUI in cases where a woman has produced eggs through her own menstrual cycle or with the help of ovulation-inducing medications.
