PURPOSE: The fertility potential of boys with cryptorchidism may be related to the number of adult-dark spermatogonia per tubular transverse section (Ad-S/T) in testicular biopsies taken at orchiopexy. Placental-like alkaline phosphatase (PLAP) positive gonocytes in testes within the first year of life indicate the preserved ability for germ cell transformation. The aim of the study was to relate these parameters to the total tubular germ cell number (S/T) and other factors associated to the fertility potential. METHODS: 89 boys 0.7-3 years (median:1.8) with bilateral testicular biopsy at bilateral orchiopexy and blood samples for gonadotropins and inhibin-B. RESULTS: In boys with Ad-Spermatogonia 58%(44/76) had normal mean S/T compared to 15%(2/13) among boys without Ad-Spermatogonia(p<0.05). In the group with a good fertility potential (n=30) including normal mean S/T, normal gonadotropins and normal inhibin-B the mean Ad-S/T was median 0.081 compared to median 0.031 in the group of patients with low fertility potential (n=38) including impaired S/T, and/or low inhibin-B but no reactive increase of gonadotropins (p<0.05). The group with increased gonadotropins (n=21) had mean Ad-S/T with median 0.063. 60%(12/20) of the patients with normal mean Ad-S/T belonged to the group with good fertility potential including normal mean S/T, normal gonadotropins and inhibin-B compared to only 26%(18/69) of boys with impaired mean Ad-S/T (p<0.05). In boys with a normal mean S/T 57% (26/46) had PLAP positive cells compared to 33%(14/43) in boys with decreased mean S/T, (p<0.05). CONCLUSION: Notification of PLAP positive gonocytes and Ad-S/T are important parameters related to the fertility potential of cryptorchid testes.
