Below are a few tidbits of what you need to know. The video is even more helpful.
– As a baby boy grows inside the womb, his testicles form inside his abdomen and move down (descend) into the scrotum shortly before birth. If that move or descent doesn’t occur, the baby is born with a condition known as undescended testicles. (kidshealth.org)
– An undescended testicle is typically detected shortly after birth. For most boys, the problem corrects itself within the first few months of life. (mayoclinic.com)
– If the testicle hasn’t moved into the scrotum by the time your son is 4 months old, the problem probably won’t correct itself. (mayoclinic.com)
– Surgery (orchiopexy) to bring the testicle into the scrotum is the main treatment. Having surgery early may prevent damage to the testicles that can cause infertility.
– The exact cause of an undescended testicle isn’t known. (mayoclinic.com)

One of our son’s has “one” that likes to creep back up, so we’ve heard about this from the doc. It’s not something you would think of checking on your baby boy, but something to think of the next time your changing diapers. As they get older, you teach them to check themselves. If you start early, it takes the awkwardness out of the conversation. Glad you brought the subject up though, people forget that boys have “issues” too.
Hello! Yes – we had the same issue and it feels sooo taboo to even mention it out loud. Thanks for commenting though – boys do have issues because I’d never even heard of this.
