Question

A boy born in 2007 and a girl born in 2005 had sexual intercourse. How likely is it for them to get pregnant, or is it not possible?

Answer

According to your description, if the girl is about to start her period and the intercourse occurs during the ovulation period, there is a possibility of pregnancy, but the probability is not very high. At 11 years old, the boy’s sperm has not fully matured, and at 13 years old, the girl’s eggs have also not fully matured. In such a case, the probability of pregnancy is low, but it cannot be ruled out. It is recommended not to attempt this lightly.
