There are literally millions of sperm in each ejaculation - so even a small amount of semen is going to contain more than enough sperm to fertilize a mature egg cell - it only takes one to get the job done.
Always use Birth Control and condoms, they prevent pregnancy and sharing STDs.
About a teaspoon- 5 cc's. Sometimes more, less as you get older.
If the semen of the male comes in contact with the vagina of a female, there is always a chance of pregnancy.
In a one ejaculation there could be anywhere in between 40-600 million sperm. Averaging half a teaspoon. Assuming you are asking about human semen, production ends at death, so the amount of semen production for any one man could be quite large. An average ejaculation is said to produce about 2 ml of semen. Semen is a combination of sperm and fluids produced in the prostate and urinary tract to move the sperm into the vagina. Sperm production can decrease with age due to lessening of testosterone, and the amount of fluids can also deteriorate with age. The prostate starts having problems. I really have no idea how someone came up with the "average" volume of ejaculate. The idea of "sampling" a sufficiently large number of men ejaculating for scientific purposes boggles my mind.
Most 14 year-old guys might be worried about the amount they ejaculate. At this age, you become a man and you can get various amounts of semen, which is normal for teenage boys. But typically, by the time he is 14 a boy will shoot his semen rather than dribble, as he's no longer a little boy. I would say he can shoot around 8 squirts, sometimes less and sometimes more.
There is no specific amount at all. Some will be able to ejaculate a bit, some a bit more and others not at all. It all depends on where you are in Puberty and if you are early or late starter. The average amount for an adult is 5ml or a teaspoon.
Viagra will have no effect on the semen and chances of getting pregnant
the chance of you becoming pregnant from that are slim to none, mainly because you are on birth control, and the only way to become pregnant is if the semen enters the uterus, if there was so semen on your underwear you are not pregnant!
Yes you can. Chances are not as high as to is you were not on your menstrual cycle but, you still can.
There are very less chances of you getting pregnant. But never the less they are there. Sperms do not survive in plane water. They may survive is isotonic saline.
As long as the semen is contained in the condom and none leaked out, then you should not be pregnant,
No, semen is just the transporter fluid, it's the sperm that gets you pregnant.
Think of it this way. If a male has recently ejaculated, the semen comes out. But not all of it. If he were to have sex with a female sometime later, the "pre-cum" would contain the semen that was left behind from the previous ejaculation. The chances of getting pregnant from this is not as high as the whole ejaculation. But why take the risk?
No she can not get pregnant from semen on her hand.
Semen has to be inside the vagina for you to get pregnant.
== == First of all, you can't stick a sperm inside you with your finger. The least amount of semen that you can hold on your finger contains millions of sperms. Though fertilization of the ovum needs millions and millions of sperms, and also depending on their motility, It is possible to get pregnant this way. It has very low probability, but could happen.
No, animal semen cannot get a human female pregnant. Only human semen can impregnate a human female.
Semen is sperm, and all it needs to do to get a girl pregnant is be fresh and be introduced to the vagina. So yes. changes are just as much as if you would have ejaculated in the vagina. There are millions and millions of sperm a droplet of sperm and there only needs to be one to fertilize and egg and get a girl pregnant.
