Recent incidence of urinary tuberculosis: A review.

Relationship of Primary Site of Testis to Final Testicular Size in Cryptorchid Patients

“…It is generally believed that testicular size is the best primary assessment of spermatogenesis, since the tubules and germinal elements account for approximately 98% of the testicular mass (Takihara et al, 1987). A decrease in the number of germ cells leads to testicular hypoplasia and satisfactory spermatogenesis is presumed to be possible only in a testis of normal or near normal size.…”

“…For these reasons it has been recommended that orchiopexy should be performed as early as possible, probably late in the first year, in order to preserve subsequent fertility (Hadziselimovic, 1982;Kogan, 1988). However, the outcome in terms of fertility has not been evaluated adequately by follow-up.The results of semen analysis were reported in men who had undergone orchiopexy for cryptorchism at or after 7 years of age; the important factors in predicting fertility were whether the condition was unilateral or bilateral and whether or not the testes were palpable (Puri and O 'Donnell, 1988).Since the bulk of the testis is composed of seminiferous tubules, measurement of testicular Accepted for publication 7 December 1989 volume has been used to estimate tubular function and a positive correlation has been reported between testicular size and spermatogenesis (Sherinset al, 1978; Comhaire et af., 1987;Takihara et al, 1987). No data are available on testicular volume in men operated on for cryptorchism in childhood.…”
