Yes it could happen coz one sperm cell is needed by the woman's egg cell. the motility of the sperm makes the difference here after God's desire.
No, sperm are required for pregnancy.
No, sperm doesn't cause early miscarriage.
Not unless you can transfer sperm from your mouth down into her eggs.
It is possible for those sperm to find their way into the uterus and cause pregnancy.
Not normally, no. It could only cause pregnancy if there was sperm on his fingers. However, even if he did it would be unlikely to cause pregnancy. Still, it is important to make sure there is no sperm on his fingers if he is going to touch her.
No. For pregnancy to occur there needs to be sperm.
Pre-ejaculate (pre-cum) does have a small amount of sperm in it, so it is possible, but the amount in it is relatively small, so the risk of pregnancy is minimal. The greater risk is in sexually transmitted disease.
No.
Depends where the semen is, if it is inside, yes.
This can be consdiered a form of birth control. Sperm in the mouth does not cause pregnancy. Sperm elsewhere can. Keep the sperm where it will do the least harm.
No. If a woman is infertile, sperm will have no effect on her. Infertile means she cannot get pregnant.
Yes, pre-ejaculate can result in pregnancy. Pre-ejaculate itself doesn't contain sperm, but if the man ejaculates and doesn't urinate sperm can remain in the urethra and thus be carried along by the pre-ejaculate. Although the number of sperm that could be in pre-ejaculate are only small compared to how many are in ejaculate, there is still a risk of pregnancy.
