The human male penis contains approximately 8290 ± 2553 axons, distributed across 25–45 loosely packed nerve bundles.
Here's a more detailed breakdown:
- Nerve Bundle Count: There are roughly 25 to 45 nerve bundles located within the penis.
- Axon Count: Each penis contains around 8290 axons, with a standard deviation of approximately 2553. This means that the actual number can vary between individuals.
- Myelination: About half of the nerve bundles are myelinated. Myelination is the process of coating nerve fibers with a fatty substance (myelin) which helps to speed up nerve impulse transmission.
It's important to note that the data on nerve counts comes from studies using donated tissues post-mortem. Tissue degeneration in older individuals may affect the accuracy of these counts. Further research could refine these numbers.
