  • Pregnancy success rate of up to 20%1.
  • Prevention of backflow of semen into the vagina5.
  • Prolonged exposure of the spermatozoa (Sperm cell) to the cervical mucus5.
  • Enables sperm to bypass the vaginal environment quickly, reducing the risk of sperm loss in the vaginal tract5.
  • Considered a less invasive method of aiding in conception with a limited number of risks6.

“In general, the natural chance of pregnancy per month of ovulation depends on the age of the woman, starting at 20% in her 20s for a couple with proven fertility in the past and dropping by 5-10% every ten years (to 15% within her 30s and to just 5% within her 40s).”
