Low Semen Volume
Low semen volume refers to the consistent finding of low volume of ejaculated fluid on semen analysis. This is usually defined as a semen volume consistently less than 1.5 mL. It is important to remember that this semen parameter is highly variable and depends critically upon an appropriate abstinence period of at least 2 days prior to sample collection. Low semen volume (or perceived low semen volume) may be a bothersome symptom for which a man seeks clinical evaluation and treatment, or may be discovered during evaluation for subfertility.
