It is entirely possible for a 13 year old to impregnate a 20 year old and it has happened.
But be aware that it would be illegal and probably constitute statutory rape in most states and countries.
No, they cannot because girls cannot get each other pregnant. If you are asking whether a 13 year old can get pregnant by a thirteen year old boy, then the answer is 'yes'. If he is producing sperm and she is producing eggs and they have sex, it is possible for her to get pregnant.
yes
No.
I certainly hope not since it is against the law to have sex with a 13 year old.
A thirteen year old girl can get pregnant if she has started ovulating and has unprotected sex.
yes.
25 or 13 or 81, age difference is not a factor in getting pregnant.
yes Because My stepsister got pregnant when she was 13 so u can 2
Yes
yes it is very possible if the teenager hasn't had her time but i dont think they can marry
A 13-year-old boy absolutely CAN impregnate a girl. Use condoms!
if you are asking can you get pregnant by self masturbation the answer is NO
