possible pregnancy

If a woman swallows semen(oral sex) and it goes in the blood is it possible to get pregnant?

You cannot get pregnant from swallowing semen.

 

Std's are possible, but not pregnancy..

It is totally imposible!  In any event the semen would be digested and the digestive and reproductive systems are completely separate.

The semen has to be deposited in the vagina. The sperms swim up through the womb into the fallopian tube.  If it meets an egg released from the ovary fertilisation may occur.  If so the egg travels on and may implant in the womb = pregnancy

Nothing travels through the blood

It is not possible to get pregnant by swallowing semen.

It's impossible to get pregnant from oral sex. 

But it is very likely to catch STDs so be safe. 

It is - of course - only possible to get an STI through oral sex if the other person has one.

they do not just appear ...
