Explain the different interpretations offered by these two tests.

1. 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.
