Family, Pendolo

A father (or dad) is a male parent or Individual progenitor of human offspring. The adjective "paternal" refers to a father and comparatively to "maternal" for a mother. The verb "to father" means to procreate or to sire a child from which also derives the gerund "fathering". Fathers determine the gender of their child through a sperm cell which either contains an X chromosome (female), or Y chromosome (male). Related terms of endearment are dad, daddy, pa, papa, pop and pops

A paternal bond refers to the relationship between a father and his child. In the U.S., legal paternity is presumed for the husband of the mother unless a separate action is taken; an unmarried man may establish paternity by signing a voluntary recognition of paternity or by taking court action. Paternity may also be established between a man and a younger person, commonly in adoption, without the two being biologically related.

The father of a child can develop the bond during the pregnancy of his partner, feeling attachment to the developing child. Research indicates that this may have some biological basis. Statistics show that fathers' levels of testosterone tend to decline several months before the birth of the child. Since high testosterone levels seem to encourage more aggressive behaviour^{[citation needed]}, low levels may enhance the ability to develop a new relationship bond (i.e. with the child).

Fathers find many ways to strengthen the father-child bond with their children, such as soothing, consoling, feeding (expressed breast milk, infant formula, or baby food), changing diapers, bathing, dressing, playing, and cuddling. Carrying the infant in a sling or backpack or pushing him or her in a baby transport can build the bond, as can participating in the baby's bedtime routine.

A parent (from Latin: parēns = parent) is a caretaker of the offspring in their own species. In humans, a parent is of a child (where "child" refers to offspring, not necessarily age). Children can have one or more parents, but they must have two biological parents. Biological parents consist of the male who sired the child and the female who gave birth to the child. In all human societies, the biological mother and father are both responsible for raising their young. However, some parents may not be biologically related to their children. An adoptive parent is one who nurtures and raises the offspring of the biological parents but is not actually biologically related to the child. Children without adoptive parents can be raised by their grandparents or other family members.

A parent can also be elaborated as an ancestor removed one generation.
