As Austin Powers once told Dr. Evil "I can see your nuts."

wtf

That's for n00bs who aren't proficient at taking nut-shots yet. Obviously Rebellion realized during testing the majority would need another mechanism to kill them zombie nazi buggers, so they introduced the head-shot. Much easier to do, and it's proven to be a wise decision, since now not only die-hard old-skool highly skilled nut-shooters are enjoying this game, but also the head-shooting casual tourists.
Besides, there's another head right there where the nuts are.

isn't the goal to shoot them in the head

hmm

Skill. Pure skill. There's no luck involved whatsoever I can assure you.

wtf lucky

These bullet-cam X-ray shots clearly show nuts, therefore zombies have nuts. Furthermore, being a nut-model in daily life, I recently had a photo-shoot, for the proctology insider monthly magazine, which included x-rays from different angles. Comparing these with the nut-textures Rebellion used on their nuts, I can see how they took real nut-x-rays and zombified them with what most likely is a propriety nut-zombification shader technique. Therefore, taking the historical accuracy and eye for detail Rebellion shows with this game into consideration, I must conclude that, at least back in the day, zombies, male ones, indeed had nuts.

theirs no nut shots in this one their zombies
