Low ejaculatory volume may indicate?
- A.
Retrograde ejaculation
- B.
Obstruction of ejaculatory duct
- C.
Incomplete collection
- D.
Androgen deficiency
Correct Answer(s)
A. Retrograde ejaculation
B. Obstruction of ejaculatory duct
C. Incomplete collection
D. Androgen deficiencyExplanation
Low ejaculatory volume may indicate retrograde ejaculation, obstruction of ejaculatory duct, incomplete collection, and androgen deficiency. Retrograde ejaculation occurs when semen is redirected into the bladder instead of being expelled through the penis. Obstruction of the ejaculatory duct refers to a blockage that prevents semen from being ejaculated properly. Incomplete collection refers to the inability to collect a sufficient amount of semen during ejaculation. Androgen deficiency, which is a lack of male sex hormones, can also lead to low ejaculatory volume.Rate this question:
