None, as long as there was no contact with the interior of the vagina by anything that came into contact with the semen.
If the semen of the male comes in contact with the vagina of a female, there is always a chance of pregnancy.
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.
The first is the concentration of sperm cells in semen - the higher the concentration better the possibility of conception. The second is the percentage of normal sperm cells - the lesser the number of abnormal sperm cells, the better the possibility of conception.
At 13-years-old a boy may not yet be producing any semen. Puberty ranges are different for every boy so it is not possible to be precise for individuals. It can be anywhere from nothing to full adult production !
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.
Viagra will have no effect on the semen and chances of getting pregnant
Yes you can. Chances are not as high as to is you were not on your menstrual cycle but, you still can.
if a man has been on that stuffed animal naked and some...residue...came off, then u can be pregnent by humping it naked
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?
Yes you can get pregnant this way, as all it takes is one sperm to enter her vagina to get pregnant. As they move fast and can not be seen with the naked eye.
No she can not get pregnant from semen on her hand.
Semen has to be inside the vagina for you to get pregnant.
Generally, no. Although pre-cum can contain sperm, there is not a lot of it. Sperm require fluids to move in, and this is restricted by clothing. Unless there is penetration, and his pre-cum or semen enters your vagina directly, the chances of pregnancy are fairly low.
Oh no. As long as semen can find its way inside the girl's vagina she can get pregnant. Doesn't matter if she's entirely naked or have some clothes on. You need to do a lot of homework before you're ready to start having sex.
