Answer:
the movements of sperm cells.
Step-by-step explanation:
The structure of mature sperm can be divided into two regions: the head and the tail or flagella. In the head there is the nucleus and a specialized lysosome, the acrosome, as well as a small amount of cytoplasm and cytoskeleton structures. The tail contains a central axoneme, composed of microtubules and surrounded by dense fibers that extend from the head to near the final end of the flagella. The tail is very important for sperm movement, so we can conclude that if a drug interferes with the formation of one of its structures, such as the microtubules, for example, that drug will completely disrupt the movements of sperm cells.
