Semen Analysis for Evaluation of Fertility in Untreated Unilateral Cryptorchidism / 대한비뇨기과학회지

ABSTRACT

In order to clarify high incidence of impaired fertility associated with unilateral cryptorchidism, this clinical study was made on 21 cases of unilateral cryptorchidism from the Department of Urology National Medical Center during recent 5 years. Fertility was evaluated by seminal quality, testicular gross anatomy and cryptorchid testicular histology. Examination of the seminal fluid that included sperm count, motility and morphology was performed according to the standard method. The result of our seminal studies showed that 38% (<20 millions) or 47.6% (<40 millions) of the unilateral cryptorchids were oligospermic. The incidence of oligospermia is significantly higher in individuals with an apparently normal solitary testis than in the general population.
