Are babies born with testicles

Male newborns have the same anatomy as an adult male, except in size. The testicles rest inside the abdomen but descend prior to birth to rest inside the scrotum; some newborns can have an undescended testicle (usually one but can be both) which means the testicle never made its way down into the scrotum. This usually requires surgery to move the testicle down into the scrotum.

Female babies have the same anatomy, inside and out, as an adult female. In rare circumstances, a female newborn may have abnormalities involving the outer genitalia which is corrected by surgery.

In some births, the newborn can have external structures of both male and female.

In some births, the genital abnormalities make it difficult to tell whether the baby is male or female; sometimes it takes several weeks or even chromosomal testing to determine the baby's sex.
