A Family Doctor's Tale - UNDESCENDED TESTES

DOC I HAVE UNDESCENDED TESTES

Undescended Testis is incomplete or improper descent of one or both testes through the  canal which is the tunnel which leads the spermatic duct from the abdomen to the testis.

The causes of  Undescended Testis are:
1.Normally the testes in the fetus are in the abdomen and make their way to the inguinal canal by the 23rd week of pregenancy and enter the scrotum by the 39th week of pregnancy.

2.Sometimes one or rarely both testes fail to enter the scrotum before birth.They may remain in the abdomen or may be not fully descended to the scrotum at birth.

3.The undescended testes can either be normal or dyplastic(cells may turn abnormal)

4.Intra-abdominal testes may be unable to produce sperm and also susceptible to malignant change.

5.Testis situated outside the usual course of descent is termed ectopic.

Diagnosis:
All male babies are examined at birth to determine whether their testes have descended into the scrotum normally.

Where the testes are not found in the scrotum an ultrasound scan of the pelvis can determine where the testes are located.

Where there is no testes to be found, a human chorionic gonadotrophin test help to rule out anorchia(complete absence of testes) and whether there is a need for counseling later on at puberty.

The complications for Undescended Testis are:
Untreated undescended testes may have increased risk for

1.infertility

2.testicular torsion

3.malignant change

The treatment of Undescended Testis is:
1.In the absence of both testes, there is nothing that can be done.

2.If there is one Undescended Testis, the testis can be brought down to their scrotum.
Similarly if both testes are undescended the testes can be brought down to the scrotum by surgery.

This surgery is preferably done between 2 to five years old.

3.If there is associated indirect inguinal hernia that should be repaired simultaneously.

4.In some cases descent of the testes may occur up to the 3rd month of age.So hypermobile testes found at birth are observed if they can descend by themselves by that age.

The Prognosis of Undescended Testis is:
Most cases of Undescended Testis usually will recover with proper surgical treatment.

If there is bilateral occurence of undescended testes and test shows that they are intra-abdominal, there is high risk of subfertility or sterilty.

Even a single viable testis can have good prognosis for fertility.

Very rarely there may be complications such as postoperative infections or recurrence.
