Children with untreated testicular hiding are at risk of atrophy, twisting, reducing sperm production, even cancer.
Doctor, Doctor Nguyen Hoai Bac, Head of the Department of Namology and Sexual Medicine, Hanoi Medical University Hospital, said that a testicular hiding is a birth defect that makes one or two testicles of a child not located scrotum that is in another unusual position such as a deep groin or in the abdomen.
The rate of full-term boys with testicular latency accounts for 3-5%, about 4 babies out of 100, and 30-45% of premature babies, have this defect. At the age of 6 months to one year and older, the rate of sick children is approximately 1%. Unilateral testicular hiding four times more than bilateral hiding. Specifically, the bilateral hidden testicle accounts for 23% of the cases, the right testicle is hidden 46%, the left testicle is 31% hidden.
Normally, the transfer of the testicles from the abdomen to the scrotum takes place starting from the 10th week of pregnancy and ending, fixing in position by the 35th week of pregnancy.
This process is governed by a number of factors such as endocrine, the role of the scrotum ligament to help move in the correct position. There is also stimulation dependence of the genital femoral nerve impulses to cause rhythmic contraction of the scrotum ligaments, the rapid development of the abdominal organs creates great pressure in the abdomen, helping to push the testicles. scrotum.
Some risk factors such as preterm, low birth weight; a family history of father, brother or sister with hidden testicles; high mother’s age; mother is pregnant many times or has a chronic medical condition; smoking, drinking alcohol or caffeine during pregnancy, or being exposed to endocrine chemicals.
Complications are common when the baby has hidden testicles
The testicles have two main roles: male hormone production and sperm production. However, in infants and pre-puberty children, the role of the testes in the body is very limited. Therefore, the testicles are hidden in this period almost without affecting the physical, as well as intellectual development of the child.
“Children with hidden testicles are still developing normally like many other children”, the doctor emphasized. “But it has consequences and complications as a child reaches puberty and adulthood.”
Usually, the most suitable temperature for testicular growth is 33-35 degrees Celsius. To ensure this temperature, the testicles must be low at the scrotum position. In a higher temperature environment such as groin, thighs, abdomen, testicles will be hampered in growth, degeneration and shrinkage.
High temperatures also cause the germ cells of the spermatogenesis tube (the cells that when a baby will play the role of spermatogenesis) to be damaged and degenerated, leading to a decrease in sperm production.
Testicular located in the inguinal canal are at greater risk of injury from impact than testicles located in the scrotum. When the testicles are not fixed in the scrotum, easily mobile, the risk of torsion is 10 times higher than normal.
In particular, the hidden testicles often have a morphological change in the germ cell. These cells can degenerate and progress into cancer cells. Studies in the world all show that the risk of stem cell cancer increases 5-10 times in patients with latent testicles. About 2 to 6% of men with latent testicles will develop germ cell tumors in the future, meaning that for every 100 children with latent testicles, 2-6 will develop cancer. Approximately 10% of stem cell cancer patients have a history of latent testicles.
Children with hidden testicles without treatment, when growing up with understanding and comparison with other children, see a lack of masculinity, concerns about aesthetics, the future. Children with low self-esteem, guilt, anxiety, depression.
Doctors recommend that hidden testicles should be detected early and treated when the baby is one year old. After one year, the hidden testicles cannot move down on their own, but begin to have structural and functional changes in the worsening direction, requiring surgery.
Parents, if they suspect that their child has hidden testicles, should take them to the hospital for examination and treatment, to help their child develop normally as many other children.
