Sperm in the lumen are unable to move independently and require to move through the tubules of the testes.

I believe the answer would be semen

The correct answer would be smooth muscle contractions.

The testes ducts include seminiferous tubules, rete testis, epididymis, vasa deferens and urethra.

The seminiferous tubules serves as the site of sperm formation. They then migrate to epididymis for storage and maturation.

The sperm then migrate to vasa deferens from epididymis when the penis gets erected.

When sufficient stimulation is achieved, the vasa deferens propels the sperm forward with the help of smooth muscle contractions.

How do will it affect the following with his ability to perform certain activities?

#1-A) If he damaged his Occipital lobe which is the rearmost area of each cerebral hemisphere he will have problems with his vision since the occipital lobe is almost exclusively devoted to the sense of vision.

#2-B) If he damaged his Hippocampus he would have memory problems since it is crucial in memory formation of new long-term declarative memories.

#3-C) If he damaged his Hypothalamus he would have serious problems with maintaining homeostasis functions like eating, drinking, temperature control, sleep/wake and BP,HR. It regulates many of the basic functions of our body. In other words it would be serious if there was damage.

#4-D) If he damaged his Amygdala he would have problems with his emotional state since it is a small temporal lobe structure next to and interconnected with the hippocampus with the crucial roles in acquisition of conditioned emotional responses and encoding storage of emotional memories.

#5-E) If he received damage to the broncos area he would have problems with speech. Since the broncos area functions is to direct the muscles that are involved in speech production. In other words he would not be able to speak words but would not have problems with knowing what he or she wants to say.

#6-F) If he received damage to the Wernicke's area he would have problems with making sente out of written and spoken language. The reason being that its function is involved with the understanding of written and spoken language. He would still be able to form words, but sentences would not make sense.

I hope it helps, Regards.
