How Likely Is the Pregnancy of a Boy and a Girl Who Have Had Intercourse?

Question

A boy born in 2007 and a girl born in 2005 have had intercourse. How likely is the possibility of pregnancy, or is it absolutely impossible?

Answer

Even if the girl is about to start her period and intercourse occurs during the ovulation period, the likelihood of pregnancy is still low because the boy’s sperm is not fully matured at 11 years old, and the girl’s eggs are also not fully matured at 13 years old. However, the possibility of pregnancy cannot be completely ruled out, so it is recommended not to attempt it lightly.
