It is not always known why this happens. It is thought to be a problem with the way the testicles develop.
Things that may raise the risk of this problem are:
- Low birth weight
- Being born too early
- A family history of undescended testicles
- Klinefelter syndrome or other chromosomal problems
- Factors in the mother during pregnancy, such as:
- Cigarette smoking
- Gestational diabetes mellitus
- High levels of alpha-fetoprotein
Treatment is needed to avoid problems, such as infertility and testicular cancer.
- Waiting for the testicle to descend on its own
- Surgery to move the testicle down and stitch it into place
- Hormone therapy (not common)
