My boyfriend and I split up for a small period, he had sex with a girl and now she has had a baby. He is now waiting for a test to see if baby is his. Although this is all happening he claims he did not , but a small amount may have come out. Could this be enough for him to be the father?:confused:

Yes,it only takes one sperm to fertilize an egg.

Sex = possibility to be pregnant. Period.

If he had sex, then yes, it is possible.
