Pre-ejaculation?

Question

This is purely just out of curiosity so please no comments on how stupid I am to do something like this cause I didn't - what are the statistics on pre-ejaculation causing pregnancy?

Answer 1

There is some sperm in pre-ejaculate, but it's not as high as regular ejaculate. And most of the sperm in pre-ejaculate are not viable.

Some teenage pregnancy sites will put statistics up to scare teenagers. The pullout method is not a good b/c method, but really only because it's used incorrectly a lot of the time. I know several couples who use it and use it correctly and have not had unwanted pregnancies.

Here's an article I found that might help you. It was actually done to study HIV, but they also found that there are not viable sperm in pre-ejaculate:

Researchers find no sperm in pre-ejaculate fluid.

[No authors listed]

PIP: A study in Boston, Massachusetts, and another study in New York City examined samples of pre ejaculate fluid from HIV seropositive and HIV seronegative men to determine whether HIV was or was not present in pre ejaculate fluid. The researchers found macrophages and CD4 lymphocytes in most samples, indicating that HIV was present. The more significant finding, however, was that most pre ejaculate samples did not contain any sperm and those that did had only small clumps of a very small amount of sperm which seemed to be immobile. A larger study is needed to verify these results. If these results are confirmed, they may dispel the myth that pre ejaculate fluid contains sperm. An ongoing WHO/USAID study shows that the pregnancy rate caused by men with 3 million sperm/ml/ejaculation is very low; fertility clinics consider men with a sperm count of no more than 5 million/ml to be infertile, particularly if is there is low motility. The average ejaculation has about 100 million sperm/ml, but about 10 million sperm pass through the cervical mucus, about 1 million make it to the top of the uterine tract, and just about 100,000 sperm reach the fallopian tubes. Thus, only a couple of sperm, assuming motility, would reach the fallopian tubes in the case of the pre ejaculate samples with some sperm, which tended to be immobile (sperm levels only in the 1000s). Thus, the probability of pregnancy is very love if pre-ejaculate fluid enters the vagina. Pre-ejaculate fluid of 6 of the 9 HIV seropositive donors in Boston and 6 of the 14 HIV seropositive donors in New York contained HIV, regardless of symptom status or antiretroviral therapy status. Thus, the risk of HIV transmission may be higher than unplanned pregnancy, so people should use condoms before the penis enters the vagina, mouth, or anus.

Journal of Assisted Reproduction Genetics, 2003 Apr;20(4):157-9. Zukerman asked "Does preejaculatory penile secretion originating from Cowper's gland contain sperm?" - conclusion: "Preejaculatory fluid secreted at the tip of the urethra from Cowper's gland during sexual stimulation did not contain sperm and therefore cannot be responsible for pregnancies during coitus interruptus."

Here's another two studies that were studying the HIV viral load in pre-ejaculate and incidentally showed that there isn't sperm:

What these scientific findings suggest is that precum either does NOT contain sperm AT ALL, or that there is so little that the chances of pregnancy are very VERY low. The chances are not eliminated but they are so low that becoming pregnant from pre-*** easily becomes urban myth.

Also remember, if the man has ejaculated before you have intercourse again, the chances are increased for conception because semen will still be left within the penis itself and further along the male reproductive organ.

Obviously, use contraception and if you miss a period or have signs of pregnancy get tested and find out.

Don't forget your common sense in light of science (e.g. use contraception, always, and every time!). More importantly, don't use other's common sense in place of science (e.g. people think scaring you will make you use contraception and/or stop having sex. Psychology tells us punishment (scaring you) is one of the least effective ways to stop you and change your future behavior - from a behavior stand-point that is. Only you can stop yourself in the end, and only you can discipline yourself. With your actions you will reap your own rewards. Think smart, plan ahead, and act smart.)

Answer 2

You're not stupid, hun. It's an honest question that many people don't know the answer to. Contrary to what some believe, pre-ejac DOES contain sperm, and you can become pregnant. I'm not sure that you'll find exact statistics, but this was the best answer I found through my own research. I hope it helps.

Yes, a woman can get pregnant even when ejaculation doesn't occur within the vagina. This is because pre-ejaculation fluid may contain some sperm.

Withdrawal of the penis from the vagina before ejaculation is one of the oldest methods of birth control. But fewer than 3 percent of adults in the United States use it as their primary method of contraception. The failure (pregnancy) rate is high. About 20 percent to 25 percent of women who rely on the withdrawal method become pregnant each year.

Answer 3

Pre-ejaculate (additionally prevalent as pre-ejaculatory fluid or Cowper's fluid, and colloquially as precum) is the sparkling fluid this is issued from a guy's penis whilst he's sexually aroused. The fluid is oftentimes secreted by skill of Cowper's glands for the period of masturbation, foreplay or at an early point for the period of intercourse, it sluggish in the previous the guy completely reaches orgasm and semen is ejaculated.

Answer 4

I'm not sure of the statistics but I heard it is possible depending on how fertile you are at the time. Here is a link with a similar question. Maybe that will be of some help.

Answer 5

pre, post or ongoing ejaculation can cause pregnancy when the dick is inside you and the egg is ready for fertilization. I trust dad.

Answer 6

You don't need numbers to tell you anything.
All you need to know is it's just as potent as the
full ejaculation.

Answer 7

High. Pre-*** is just as potent as the main ***.
