The aim of this study was to investigate to what extent the fertility potential was impaired in boys with such testes compared to the fertility potential of boys with late referral congenital cryptorchidism. Materials and Methods: A total of 153 consecutive boys underwent bilateral orchiopexy at age 2 to 7 years (median 3.9) between 2011 and 2018. Of the patients 67 were diagnosed with bilateral ascended testes and 86 with late referral bilateral congenital cryptorchidism. We assessed serum levels of inhibin B and gonadotropins and histological parameters, number of germ cells per tubule cross-section and number of type A dark (Ad) spermatogonia per tubule cross-section. All values were compared to our normal material. Results: Number of germ cells per tubule cross-section of boys with ascended testes (median 0.50, range 0 to 2.29) was not significantly higher compared to boys with congenital cryptorchidism (median 0.37, range 0 to 2.57; p=0.11). Mean number of germ cells per tubule cross-section was below normal range in 40 boys with ascending testes (60%) vs 57 boys with late referral congenital cryptorchidism (66%, p=0.40). Biopsies absent of Ad spermatogonia were noted in 31% of boys with ascending testes (21 of 67) vs 34% of boys with congenital cryptorchidism (29 of 86, p=0.76). Serum levels of inhibin B and gonadotropins did not differ between the 2 groups. Conclusions: The fertility potential of boys with bilateral ascended testes was impaired to almost the same level as that of boys with bilateral congenital cryptorchidism and should therefore be surgically corrected as soon as the diagnosis of ascended testes is settled.
