IUI, or intrauterine
insemination, ensures that sperm are placed in the reproductive
tract at the time of ovulation. It is used both with and without
fertility medications. For this process, the woman's follicle
maturity is monitored by blood and ultrasound tests or urine
testing. HCG may be given to release the egg when it is mature.
When sperm enter the woman's vagina through intercourse, the
seminal fluid is removed by the woman's cervical mucus. When sperm
are placed directly in the uterus, the seminal fluid is removed in
the lab before insemination to prevent uterine cramping and
infection.
Washed sperm is then placed into the uterus close to the time of
egg release. Insemination may be performed once or twice around the
time of ovulation. A variety of medications and protocols can be
used to time ovulation.
