The family is the fundamental social unit that, depending on historical and socio-economic development, gathers individuals bound by marriage and their descendants, as well as potentially broader or narrower circles of kinship, who come together to meet various biological needs, economic needs, social, educational, emotional, and other needs. In a general sense, the family is a social group of a historically variable form within which the process of reproduction takes place, including birth, growth, and death of individuals, on one hand, and occurs through processes of socialization, individualization, and the protection of the psychosocial stability and integrity of adult individuals. According to what marriage means in society, as well as what is prescribed by the Family Law, spouses are obliged to be faithful to one another, to assist each other, respect, and maintain harmonious marital and family relations. These are serious, important, and challenging decisions and obligations for anyone planning to marry and start a family. However, advances in assisted reproductive technologies (artificial insemination) have raised numerous ethical questions. Ethical issues include the risks of some infertility techniques, such as multiple pregnancies and the use of selective abortions. Others revolve around questions of what constitutes a family and the bonds within it, and whether people find it problematic for children to come into a family in ways other than through biological parents having biological children without the aid of technology.
