The endometrium is the innermost layer of the uterus that contains the lining which is responsible for accepting and nourishing a fetus during the pregnancy process. The lining of this cavity changes with every monthly cycle in response to the primary female hormones produced by the ovaries: estrogen and progesterone.
If one parent is more stable than the other, judges can decide to award primary custody to that parent. As a result, parental fitness is often a mechanism used in custody battles. Each state has its own set of rules regarding what makes a parent unfit.
The best parent for the child should have custody-with adequate rights for the other parent according to their commitment. The law is biased against fathers-people need to recognise that we do care about our children and their upbringing-you don't have to be a mother to be committed.
