It would seem the most efficient way to sterilize a population would be to make sperm immotile. Impairment of the cilia would accomplish this, and SARS-CoV-2 does exactly that. However, cilia in the human body are ubiquitous and effect far more processes than have been previously known. 

For example. Long COVID may indeed be "all in your head," and by that, I mean by disruption of the Primary Cilia in the Medulla Oblangata:

Coughing

Heart rate dysfunction

Temperature dysfunction

Acid reflux

Mood dysregulation

All reflex responses

Pain sensing

Coordination

Blood pressure dysregulation

Brain chemical balance - including serotonin

As it turns out, the Primary Cilia are vital for maintaining proper functioning of our brainstems.

Also, the nAChR connection is explained - Inactivating α7 nAChR function in vitro increases cell proliferation during the initial steps of the epithelium regeneration. 

Activating nAChRs stops epithelium regeneration. 

Your lungs cannot repair themselves.
