Question

Researchers have noticed that some men who were sterile because their sperm cells were unable to move also had chronic infections of the respiratory tract? What might be the connection between these two symptoms?

Answer 1

Kartegener's disorder

Step-by-step explanation:

The respiratory tract has cilia which move. Sperms also have a tail that moves. They both have the same protein in their structure called microtubules. There is a disorder in which there is the absence of a part in the microtubule. Dynein arms absent in microtubules. Because the respiratory system and sperm both contain cilia that's why these two systems have a connection and not work properly.
