Which activity would be prevented by blockages at X and Y for Male reproductive system

The blockage of the X and Y structures - which correspond to the vas deferens on each side in the male reproductive system- would prevent the movement of sperm out of the body.

Explanation:

The complete question is:

Which activity would be prevented by blockages

at X and Y (see image)?

In man, sperm are produced in the testicles, from where they pass into the epididymis to complete their maturation. There, in addition, a whitish and viscous liquid is produced that will help transport the sperm to the outside.

The deferential ducts (X and Y in the image) are in charge of leading the sperm to the ejaculatory ducts, to be expelled to the exterior.

Blocking the ejaculatory ducts would prevent the transport of spermatozoa to the ejaculatory ducts, which would prevent them from being expelled out of the body.
