    Repeat semen analyses not always necessary

    Second analysis warranted when sperm concentration is initially abnormal, data show


    Sperm concentration, testicle volume linked

    Analyses of data on testicular volume showed a statistically significant association between sperm concentration and total testicular volume. Sperm concentration did not correlate with volume of the right or left testis or size discrepancy between testes.

    “These findings suggest that testicular volume may be used as a surrogate measure for sperm concentration when semen parameters are not available,” Dr. Derisavifard said.

    In the future, the authors are planning to see if the number of semen analyses performed has an effect on whether a patient undergoes surgery and if there is any correlation with fertility status.

    “The limitations of our study pertain to inadequate follow-up in assessing associations between sperm concentration and clinical practice patterns, rates of clinical pregnancy, and outcomes of surgical intervention. Ultimately, concern about fertility potential is what drives further evaluation of the adolescent with varicocele and the decision to perform surgery,” Dr. Derisavifard said.

    Findings from the study were presented at the 2016 AUA annual meeting in San Diego.
