  • Title: Bilateral testicular biopsy in men with varicocele.
    Author: Ibrahim AA, Awad HA, El-Haggar S, Mitawi BA.
    Journal: Fertil Steril; 1977 Jun; 28(6):663-7. PubMed ID: 862978.
    Abstract:
    Fifty-two infertile men with varicoceles were subjected to bilateral testicular biopsy to detect the effect of the varicocele on each testis. The results indicate that varicocele can result in infertility primarily through sloughing of immature cells or through arrest of spermatogenesis at the spermatid or primary spermatocyte stage. The effect is bilateral but is more marked on the varicocele side. However, the presence of a varicocele could not explain the infertility of seven men with normal biopsies and of four men with a normal biopsy on the varicocele side and arrest on the other side.
