Q ) Fructose absence in semen analysis suggests
A. B/L vas deferens obstruction
B. Ejaculatory duct obstruction
C. Testicular failure
D. Prostatic urethral obstruction
B ) Fructose is a component of semen produced by the seminal vesicles. The absence of fructose in semen is often indicative of an obstruction at or beyond the level of the seminal vesicles, which is commonly associated with ejaculatory duct obstruction. This obstruction prevents the seminal vesicles from secreting fructose into the semen.
