Test Details
Limitations
Diagnosis is based on the absence of sperm in the antegrade ejaculate and the presence of sperm in postmasturbatory urine. Retrograde ejaculation may be suspected whenever the semen volume is less than 1 mL. To diagnose retrograde ejaculation, it is necessary to evaluate urine after an ejaculation.
This test was developed, and its performance characteristics determined, by LabCorp. It has not been cleared or approved by the Food and Drug Administration.
Methodology
Visual and microscopic
Additional Information
In males, retrograde ejaculation occurs when the ejaculated fluid, which would normally exit via the urethra, is redirected towards the urinary bladder. Normally, the bladder sphincter contracts and the ejaculate fluid passes through the urethra towards the area of least pressure. In retrograde ejaculation, this sphincter does not function properly. Retrograde ejaculation has multiple causes, including surgical (transurethral resection of the prostate), medication (eg, tamsulosin), complications of diabetes, and in male infertility.
