If you have sex with zero protection is the chance of having a kid over 50% probably? Or are there a bunch of factors that make it impossible to give a percentage?

Say someone goes out todqy and has sex with zero protection with someone. What’s the chance of them having a kid because of that?

    There are just too many factors to predict an accurate percentage.

    One single act of unprotected intercourse, with ejaculation but without knowing where the woman is in her cycle, has a surprisingly low percentage of resulting in conception. Somewhere about 5%. Of course, if you know where the woman is in her cycle and time the intercourse because of that, the odds can be much greater or much less.

    It’s very hard to tell, that’s why they pissed on barley back in the day

    There are many factors, if the woman is like 50 then the chance is probably 0%

  5. Pesec1 Avatar

    Depending on other circumstances, between 0% and about 25% for the single act.

    If they are past ovulation window, it is close to zero.

    If they time it perfectly, there is a myriad of little things that can kill the zygote before pregnancy has chance to proceed, hence only about 1/4 chance if everything is perfect.

    I mean on the surface, the odds are about 4/30 or if you boil that down maybe 1 in 7.5.

    But from there, theres an absolute ton of other factors.

    You’re best off assuming it’s 100% and just don’t.

  8. macdaddee Avatar

    It depends on a lot of factors. For example, if you ejaculate in a man’s anus, there’s a 0% chance of having a kid from that.

    No. You have a 30% chance if everything is lined up perfectly, there’s too many factors to give a true percentage unless we know exactly when they ovulate.

    Let me tell you a story about statistics. During World War II the British had to switch over to night bombing because their daytime bombing loss rate was over five percent.

    That doesn’t sound like much but if you take those losses every day it’s only a matter of weeks or months before you’re out of planes.

    If the result is disaster, sustaining a five percent risk for any length of time is highly unlikely.

    Similarly, without knowing anything else except that your chances of pregnancy are only five percent per day, and you do it every day for thirty days, you wind up with 1 – (1 – 0.05)^30 = 0.872 = EIGHTY SEVEN POINT TWO PERCENT chance of pregnancy.

    You will ruin your life playing this game. It is a statistical certainty.

    Much lower, getting someone pregnant isn’t as likely as it’s made out to be

  12. Frozen_Orange_Juice Avatar

    Don’t know any scientific probabilities or anything like that, but as a woman who has been off birth control for about 1.5 years, remains sexually active, tracks her period (which also tells me when I’m ovulating), and doesn’t use condoms, I’m still not pregnant so I can’t imaging the chances are that high if you have sex one time with no bc/protetction. I also imagine that both the male and female fertility play a role, which I haven’t seen mentioned here (besides age in relation to fertility)

    Depends on where she is in ovulation

    I’ve read that a healthy young couple having regular intercourse will lead to a viable pregnancy in 5 months on average.

    Can be on the first try, can take a while, but 5 months on average.

    Odds go down with age and various health issues.

    NOTE: THIS DOES NOT MEAN THAT YOU CAN HAVE UNPROTECTED SEX FOR A COUPLE OF WEEKS BEFORE YOU RISK PREGNANCY.

    50/50. Either you get pregnant or you do not

  16. okieS_dnarG Avatar

    Is either 0% vs 100%. With condom the odds become 0% vs <1%

    100 percent if you stick it in her ass

    One of the most important factors that nobody ever talks about is this:

    If she’s so caught up in the romance that she’s ready to throw caution to the wind because she just wants to feel you inside of her?

    She’s ovulating.

    If you’re so overcome by chemical attraction beyond what you’ve ever experienced before?

    She’s ovulating.

    It’s when it feels the best and when we feel the freest that the risk is the highest. This is why a lot of people consider forms of birth control that are impulse-proof like IUD. I wait for the day when there’s something similar available for men, too.

    If you’re both under 20 it’s pretty much 109%

  20. levinyl Avatar

    Depends on the women as well if she is ovulating the chances are much higher

  21. chippy-alley Avatar

    Its a bunch of factors

    There are pregnancies that are the result of one hit wonders

    There are people who try for years

    When my BF and I have sex with no protection, there is 0% chance of us having a kid.

  23. L1zoneD Avatar

    With my daughters mom, we only had sex once and my daughter was born. I was boning my sons mom without protection for about 5 years before she got pregnant. I’d say most comments replying with an answer here are wrong. Basically, no one knows the odds. Some people click up, and it’ll happen instantly, and others, it’ll take more time. No one here can give you a truthful percentage or odds.

    Pulling out obviously has a lot to do with this equation.

    Most men are incapable/unwilling to do it properly, but thank Jesus my dumb ass was able to do this 100% of the time when I was 19.

  25. nummakayne Avatar

    If you’re both broke and unprepared the odds are 100%.

  26. Cliffy73 Avatar

    It depends on the ages of the participants, especially the woman. If they’re both in their 20s, then the chance of pregnancy from a single unprotected sex act is somewhere around 20%. That number begins to drop pretty significantly after a woman’s mid 20s.

    Contraceptives protect against more than just pregnancy. You might not wind up with a child, maybe just syphilis. Or herpes. Or Chlamydia. Or HIV. Or anal warts. How about ghonnoreh? HPV? Take your pick

    She could be a dude, the chances drop significantly if so.

    Its most the men that are to blame for weak spermcount.

    If you check your sperm count and the female has decent eggs and is in the window, the change of pregnancy is over 80%.

    But most men have weak sperm count

    50%, either you do or you don’t.

    There is no hard and fast number, because a ton of factors influence chance of conception.

    Closeness to the ovulatory portion of the menstrual cycle has a direct influence on the overarching chances. If you can medically confirm that a woman is more than a few days past her ovulation, and that another won’t be occurring for 5 days (which is technically impossible to perfectly predict) the chances would be essentially zero. No egg, no baby.

    But there are a lot of other things. Body fat of the woman, either high or low, can impact the ability to ovulate at all. Diet, medications, cortisol levels, physical activity, mental health, quality of sperm, and a myriad of other factors all weigh in.

    Suffice to say, there is a non-zero chance of getting someone pregnant every time you have sex, assuming they have all the right physical components, you do too, and they all have the capacity to work as normal. That chance theoretically goes up to a maximum of about 15-20% the closer you get to the actual event of ovulation. This is misleading though, as that statistic is taken from the average time to conception over years by researchers.

    Best advice: always assume any heterosexual act could result in a pregnancy. Make your choices and preparations based on that idea, and you shouldn’t be too surprised with the outcome. Please note: that means that sex with spermicide, a condom, and an IUD can still result in a pregnancy. Take the risks into account before getting into the business.

    Chances are 50% / 50%
    Probability is something different

    A woman has about 20% chance of conceiving each cycle if she has sex during her fertile period. Fertile period lasts about 6 days per cycle. Once she ovulates, that egg lives for roughly 12-24 hours. Sperm has the meet that egg during that time frame. Sperm lives in body for up to 5 days. Highest chance of pregnancy occurs on day of LH peak as you are expected to ovulate within 24-36 hours. Getting pregnant is not as easy as we were led to believe in sex ed 😅

  34. Physical_Complex_891 Avatar

    Much much lower. Ovulation is only 12-24 hours long and the only actual window to get pregnant. Give or take 5 days before ovulation if the conditions are right due to sperm having the potential to live up to 5 days.

  35. remes1234 Avatar

    This can be hard to track statistically, But it is estimated that couples actively trying to concieve have a 30% to be successful in the first month, 85% with a year, and 90% within 2 years. This means that they are having multiple events, and are likely targeting fertile periods. So odds are that conceptions happen in <10% of events.

    It’s always 50/50%.

    Either there is a kid or not

  37. tolgren Avatar

    A woman is only fertile for 6 days out of her cycle. Even if you have sex within those 6 days many other factors come into play to reduce the chances.

    Not even close. A woman is not ovulating 50% of the time so even if eny time she was ovulating it was guaranteed, it would still be way less than 50%

  40. Regarded-Platypus821 Avatar

    Buncha factors. Many many factors. But if youre under age of 50 and getting somebody pregnant would be a big disaster then you gotta play like the odds are 100%.

    If you’re a teen sneaking around it’s like 100% chance.

  43. Maleficent-Flower607 Avatar

    Depends on the day of a woman’s cycle and how predictable her cycle is.

  44. Astroruggie Avatar

    Too many factors at play. When we tried to have a baby, She got pregnant at first try. Then we lost the baby and took a year or something more to conceive again, trying every time around ovulation periodo. The psycological part is underestimated but can drop your chances signficantly
