unless he has a S.T.D, no. but use a condom to be safe
Highly unlikely. No, typically the egg accepts only one sperm. Any sperm during or after the event will have no affect on the pregnancy. No
uneducated female, why would you so such a thing?
It initializes the pregnancy by supplying one half the needed DNA.
Yes it is safe.
Unlikely but not impossible
No, sperm are required for pregnancy.
No, once the egg is fertilized with a sperm and his DNA it can not be changed. The uterus closed and nothing can in in if you are referring to sex during pregnancy.
Conception is the beginning of pregnancy in that it is the joining of the sperm and egg. During implantation, the fertilized egg embeds in the uterine wall.
whoever that the sperm comes from he is the father.... how can there be another father? this situation only happens to external fertilisation organisms
If sperm does not enter the vagina, there is no chance of pregnancy. Pregnancy occurs when sperm fertilizes an egg, and this can only happen if the sperm comes into contact with the vagina and eventually reaches the egg in the fallopian tubes. Without this contact, pregnancy cannot occur.
Oral consumption of sperm will not lead to pregnancy because the sperm will never reach the egg.
A pregnancy begins with the actual act of love making. If the sperm and the egg come together and the egg is fertilised by the sperm a pregnancy begins.
