Assessment of testicular volume: A comparison of fertile and sub-fertile West African men

Conclusion Testicular volume on scrotal ultrasound correlates well with severity of oligospermia in men with sub-fertility. While the critical mean testicular volume necessary for adequate spermatogenesis has not been determined, it appears there is an optimal testicular volume of 18–20ml at which spermatogenesis is at its peak in sub-fertile Nigerian men.
