Exploratory scrototomy in 168 azoospermic males.

W F Hendry, J M Parslow, J Stedronska

    British Journal of Urology
    |December 1, 1983
    PubMed
    Summary

    Serum antisperm antibodies are linked to acquired obstructive azoospermia. Surgical treatment success, indicated by pregnancy, was higher in men with fewer antibodies, suggesting an immunological basis for treatment failure.

    Area of Science:

    • Urology
    • Reproductive Medicine
    • Immunology

    Background:

    • Azoospermia affects male fertility, with varying causes including obstruction and spermatogenesis failure.
    • Serum follicle-stimulating hormone (FSH) levels can help differentiate causes of azoospermia.

    Purpose of the Study:

    • To investigate the role of serum antisperm antibodies in azoospermic males with normal or slightly elevated FSH.
    • To correlate antibody presence with the site of obstruction or spermatogenesis failure and surgical outcomes.

    Main Methods:

    • Serum antisperm antibodies were measured in 168 azoospermic males.
    • Exploratory scrototomy, vasography, and testicular biopsy were used to define obstruction or spermatogenesis failure.
    • Surgical reconstruction included epididymovasostomy and vasovasostomy.

    Main Results:

    • Acquired blocks of the cauda epididymis and vas were more frequently associated with antisperm antibodies than congenital absence of vasa or caput epididymis blocks.
    • Young's syndrome (sinusitis, bronchitis, bronchiectasis) was linked to caput epididymis blocks.
    • Surgical reconstruction in acquired blocks resulted in sperm counts >10 million/ml in 45% and pregnancies in 21.5% of cases.
    • Lower antibody levels correlated with successful pregnancies after surgery.

    Conclusions:

    • Serum antisperm antibodies are significantly associated with acquired obstructive azoospermia.
    • An immunological basis may contribute to treatment failure in some azoospermic patients.
    • Surgical intervention shows potential for restoring fertility in specific cases of obstructive azoospermia.
