単睾丸症の臨床

Abstract

1960年より1981年までに経験した単睾丸症47例について検討を加えた

In the last 22 years (l960~1981), 47 cases of monorchism were experienced at our University ospital, i.e., in 9.6% of the 488 sides operated for cryptorchism. The majority, 24 cases, were under the age of 5 years at the first medical examination. The defect was on the left side in 32 cases and on the right side in 15 cases. Other anomalies besides monarchism were contralateral cryptorchism in 2 cases, hypospadia in 2 cases, ipsilateral inguinal hernia in I case, ipsilateral renal pelvic duplication in 1 case and XO/XY mosaicism of sex chromosome in 1 case. Oligozoospermia and normozoospermia were noted in 2 and 4 adult cases, respectively. Histological findings of contr alateral testes obtained on three adults were germinal aplasia, hypospermatogenesis and normal spermatogenesis.
