The pull-out method is not very effective during ovulation and carries a high risk of pregnancy; if you are in your fertile window, it should not be relied on as your only birth control method.

Key facts in simple terms

  • Ovulation (the day the ovary releases an egg) and the 5 days before it are the most fertile days of the cycle; pregnancy is most likely from sex in this window.
  • Even with “perfect” pulling out, pregnancy can still happen because a small amount of semen or sperm can enter the vagina before or during withdrawal.
  • With typical real‑life use over a year, about 1 in 5 couples relying on withdrawal become pregnant (around 78–80% effectiveness), and the risk is higher if sex happens during the fertile window.

Why risk is higher during ovulation

  • The egg is available to be fertilized for about 24 hours, and sperm can live up to 5 days inside the reproductive tract, so any slip during pull‑out in that time has a strong chance of causing pregnancy.
  • Because the fertile window amplifies any small error (pulling out too late, semen on fingers or genitals, or not fully clearing the urethra between ejaculations), withdrawal is especially risky at that time.

How effective is pull out during ovulation (realistically)?

There is no special “safe” effectiveness rate for withdrawal on ovulation day; instead, two things stack together:

  • Typical‑use failure rate of withdrawal (about 20 pregnancies per 100 couples per year).
  • The highest possible fertility window, meaning that if withdrawal fails even slightly, the odds that it leads to pregnancy are much higher than on non‑fertile days.

Put simply: using pull‑out during ovulation is close to “unprotected sex with a small handicap,” not a reliable contraceptive strategy.

What is safer instead?

If pregnancy would be a big problem right now, health organizations strongly recommend using a more reliable method, especially during ovulation:

  • Condoms : Also protect against STIs and are much more effective than withdrawal alone when used correctly.
  • Hormonal birth control (pill, patch, ring, shot): Highly effective when used consistently.
  • Long‑acting methods : IUDs and implants are over 99% effective and remove timing/“pull out” pressure.

If you already had sex with only pull‑out during your fertile days and are worried about pregnancy, emergency contraception (like a copper IUD, or some pills before ovulation has occurred) may be an option depending on timing; this should be discussed with a medical professional as soon as possible.
