That man would not be able to secrete sperm sort of like having a vasectomy
Vas deferens
vas deferens
The body would die.
The structure that runs down the length of the testicle and turns upward into the body where it becomes the vas deferens is the epididymis. It is a tightly coiled tube that stores and transports sperm from the testicle to the vas deferens for ejaculation.

If you were to fall into a black hole, the extreme gravitational forces would stretch and compress your body in a process known as spaghettification, ultimately tearing you apart. As you move closer to the singularity at the center of the black hole, time dilation would cause you to experience time differently compared to someone observing from outside the black hole. Ultimately, you would be pulled into the singularity, where the laws of physics as we know them break down.
Any body falling into a black hole will get completely destroyed. There is no such thing as an absolutely rigid body; a "rigid body" is an approximation that may help with some calculations, and such an approximation is valid (i.e., it's a good approximation) under certain circumstances, but a body will certainly not remain rigid under the extreme circumstances of a black hole.
This is not something that could possibly happen, so there's little point in attempting to speculate on it. A solid body the size of Antares would, however, collapse into a black hole from its own mass.
As you get near a black hole, the force of gravity is much stronger on the side of you nearest the black hole - so much so that your body (or anything else) is ripped into individual molecules. That means that your body cannot travel through a black hole . . . a bunch of molecules is no longer a body.
Then your body would no longer exist.
This cannot possibly happen, so asking what would happen if it did happen is an exercise in stupidity.
No, in cats, the urethra and vas deferens do not join as a single duct. The vas deferens carries sperm from the testes to the urethra, while the urethra carries both urine and semen out of the body through separate openings.
