You cannot "grow" testicles. But if you are male you should have testicles and they will develop as you grow.

The penis and the testicles will begin to grow more noticably at ages 12-13. If you have foreskin, your penis will begin to "come out" a little bit. If not, the area that is not layered with skin will begin to grow. Your penis length will begin to change noticably. Your scrotum (the sack containing the testicles) will begin to hang lower and enlarge. You should start to grow pubic hair. You should also become more comfortable naturally with showering in Gym or pool locker rooms. Observations of others genitals is healty if it is not done to frequently.
Cryptorchidism is a medical condition wherein the testicles are undescended. Undescended testicles are testicles that don't move lower into the scrotum.
During puberty, hair will grow around the anus and on the buttocks themselves, along with growing on the testicles, base of the penis and around it.
