If a guy has an orgasm inside a girl , what is the probability of the girl getting pregnant?

Question

please factor in the fact of not wearing any kind of protection , guy or gril.

Answer 1

I don't know if it's really possible to calculate, there are so many factors to consider:

1. How fertile the man's sperm are
2. Where the girl is in her menstral cycle
3. How fertile the girl's eggs are
4. Whether the girl had an orgasm as well and when

The list goes on, sometimes a girl will get pregnant at the same time she loses her virginity, sometimes a married couple can try for years having unprotected sex and not have a single baby. At a guess, I'd say maybe one in ten, but it's probably not worth very much...

EDIT: Okay, I was wrong, but not as wrong as some of the people here. I'm stunned that so many people think the probability is so high, I mean 80-100%??? Give me a break! In the name of the advancement of human knowledge, and proving me to be right (-er), I have done some research! Read on:

"In normally fertile couples there is a 25 percent chance of getting pregnant each cycle, meaning around 75 to 85 percent of women who have sex without using birth control will get pregnant within one year"(1)

So therefore, if you have unprotected sex every day from the time you have one period to the time you have another, there is only a 1 in 4 chance. Another website puts it higher, giving chances based on where a girl is in her menstrual cycle:

"If a woman has unprotected sex 6 or more days before she ovulates, the chance she will get pregnant is virtually zero. If she has unprotected sex 5 days before she ovulates, her probability of pregnancy is about 5%. Then, her probability of pregnancy rises steadily until the two days prior to ovulation. If she has unprotected sex on either of these two days, she has a 25-30% chance of becoming pregnant.

From that point, the probability of pregnancy declines rapidly. By 12-24 hours after she ovulates"(2)

Meaning the chance for one time is somewhere between 0 and 1 in 4, depending on what time of the month it is for you. Yet another website supports the 25% per month value:

"Actually, per month of trying the probability is only 20-25%. Thus, it usually takes a couple about 5 months to get pregnant. By the end of the first year of trying, 85% should have conceived." (3)

Of course, people are right in saying that it only takes one time, so these probabilities might give you a false sense of security, but still...

Answer 2

Well the orgasm is what makes the sperm come out so thats whats starts the whole process. The girl has to be in middle of her cycle 9 to 15 days after the beginning of the last period.

Answer 3

There is a difference bewtween an orgasm and when someone comes. You should definatly get checked out as soon as possible or if it was in the last 2 days- use the morning after pill. Always, always use protection, as you never know.

7/28 = 25%
