Explanation:

Dichlorodiphenyltrichloroethane (DDT) is a colorless, odorless, tasteless, crystalline compound. It is an organochloride. It is used as an insecticide. It is associated with damage of biodiversity and several human and animal health complications.

In human males DDT is associated with decrease in fertility. As it results in low sperm count, negatively affects the sperm motility and synthesis.

The uncoupling process will reduce ATP synthesis in the mitochondrial cells of the sperms. This may lead to low sperm motility in the vaginal canal of the female after the insemination process. Thus this will reduce the male fertility.
