A. Cosmetic reasons
B. Infertility
C. Risk of malignancy
D. Impotence
E. Abdominal pain
Ans.
(B) Infertility ; (C) Risk of malignancy :
• Early orchidopexy reduces the risk of
primary germ cell tumours of testis
There is no reliable statistics as to whether orchidopexy diminishes the
liability of malignancy. However.it does improve the prospect of early
diagnosis. [LB 24th-1404]
• Orchidopexy decreases the risk of neoplasia when performed before 10
years of age.
• The definite histological changes occur in an undescended testis by age of 6
yrs.
• Orchidopexy
should be done before child goes to school 5 yrs. of age.
After 16 years, irrevesible, destructive changes occur, halt, the
spermtogenesis, limit the androgen production to half the normal output. After
6 years, the percentage of successful operation falls in undescended testis.
— By the age of five years, both the testes should be in the scrotum. After
that age the germinal epithelium is increasingly at risk, and lack of descent
by puberty is associated with infertility. Therefore orchidopexy before
puberty may prevent infertility.
Considering the above points, it is better to do orchidopexy for reasons
— Risk of malignancy and Infertility
