Intrauterine insemination (IUI) is a fertility treatment that involves placing the washed sperms inside a woman's uterus to facilitate fertilization. It is usually combined with ovulation induction to increase the number of eggs ovulating and hence the chances of becoming pregnant. The husband is asked to give semen sample on the day of the procedure which is processed. This usually takes 30-40 minutes in case of fresh semen sample. If frozen sample is used, it is thawed and processed on the day of the procedure. Since the semen contains prostaglandins which can initiate severe uterine contractions, it needs to be washed. The washed sample is inseminated inside the uterine cavity. This bypasses the cervical mucous barrier increasing the number of sperm that reach the fallopian tubes and subsequently increase the chance of fertilization. The women is asked to rest for 15-20 minutes after the procedure. She can carry out her regular activities after IUI.
