IUI, or intrauterine insemination, is a fertility treatment that involves the direct placement of sperm into a woman's uterus during ovulation. This procedure aims to increase the number of sperm that reach the fallopian tubes and subsequently increase the chance of fertilization.

IUI may be recommended for couples facing certain fertility challenges, including:

• Unexplained infertility
• Mild male factor infertility (such as low sperm count or motility)
• Cervical factor infertility (issues with cervical mucus)
• Endometriosis-related infertility
• Couples using donor sperm

It may also be used in cases where timed intercourse or fertility
medications alone have not resulted in pregnancy.

• Increased Sperm Concentration: IUI bypasses the cervix, depositing
  sperm directly into the uterus, which can be beneficial for couples with low
  sperm count or motility.
• Enhanced Timing: By placing sperm directly into the uterus during
  ovulation, IUI ensures that sperm are available to fertilize the egg at the
  optimal time.
• Reduced Sperm Travel Distance: IUI decreases the distance sperm need
  to travel to reach the egg, improving the chances of successful fertilization.
• Controlled Ovulation: In some cases, fertility medications may be used in
  conjunction with IUI to stimulate ovulation, increasing the number of eggs
  available for fertilization.
• Minimal Invasive Procedure: Compared to other assisted reproductive
  technologies (ART), such as in vitro fertilization (IVF), IUI is a less invasive
  and less costly treatment option.
