IUI is one of the assisted reproductive techniques in which the sperm is directly injected into a woman's uterus at the time of ovulation in order to make the likelihood of conception better. Sperm preparation is done upon the quality of the sperm to improve and then it is put into the uterine cavity with the help of a catheter. This is recommended in couples who have unexplained infertility, mild male factor infertility, or even cervical problems. It is less invasive and more affordable compared to other assisted reproductive technologies, such as IVF. Maximal proximity of sperm to the oocyte during the so-called IUI will increase the chances of successful fertilization and pregnancy, hence offering a hopeful option for many seeking to conceive.
