Purpose : To investigate the relationship of MIS and cryptorchidism according to the
descending level of testis into scrotum, we studied expression degree of MIS by
immunohistochemical analysis using anti-human MIS polyclonal antibody in testicular
specimen.
Materials and Methods: MIS were stained in excised testis by trauma on each 8
patients as control group and age-matched abdominal, inguinal and prepubic
cryptorchidism.
The expression were classified as score 1, 2, 3 and 4 according to stained degree of
percentage in randomized 16 fields(x400) under the light microscope.
Results : Of the degree of MIS expression in control group, 87.5% were category 3 or
more. The mean score was 3.13¡¾0.62.
2. Of the degree of MIS expression in abdominal type cryptorchid testis group that
underwent orchiectomies, 68.7% were category 1. The mean score, 1.31 ¡¾ 0.48, showed
significant difference compared to control group(p<0.05).
3. Of the degree of MIS expression in inguinal type,56.2% were category 3 or more.
The mean score, 2.63¡¾ 0.81, showed no significant difference compared to control
group(p>0.05).
4. Of the degree of MIS expression in prepubic type, 75.0% were category 3 or more.
And the mean score, 2.88¡¾0.62, showed no significant difference compared to control
group(p>0.05).
Conclusions: Expression of MIS is different according to descending level of testis and
may play a role in physiologic changes of testicular descent.
