Exercise 4

A semen analysis on a vasovasostomy patient has a normal sperm concentration; however, motility is decreased, and clumping is observed on the wet preparation.

a. Explain the possible connection between these observations and the patient’s recent surgery.

b. What tests could be performed to further evaluate the patient’s infertility?

c. Briefly explain the different interpretations offered by these two tests.

d. State three ways in which a positive result on these tests could be affecting male fertility.

Step 1 of 4

a.

Connection between patient’s recent surgery and the laboratory observations:

• A patient has normal sperm concentration even after the vasovasostomy surgery, but the patient’s sperm motility is decreased and clumping is observed

• The possible connection between the recent surgery and the laboratory observations is the formation of male anti-sperm antibodies after the vasovasostomy procedures
