Donor Conceived People
A donor offspring, or donor conceived person, is conceived via the donation of sperm (sperm donation) or ova (egg donation), or both (either from two separate donors or from a couple). For donor conceived people, the biological parent(s) who "donated" sperm or eggs (though most commonly "donors" are financially compensated so "donor", while the most common term is a misnomer) are not legally recognized as parents and do not appear on their birth certificate. In many countries it is common for donor conceived people to be given no identifying information about their donor, however in some countries anonymous sperm and/or egg donation has been made illegal due to concerns for the medical and emotional needs of donor conceived people. Even in cases with anonymous donors, donor conceived people are sometimes able to connect with biological parent(s) and/or half siblings conceived from the same donor using DNA testing or through online registries for donor conceived people. With the sig ...

Sperm
Sperm is the male reproductive cell, or gamete, in anisogamous forms of sexual reproduction (forms in which there is a larger, female reproductive cell and a smaller, male one). Animals produce motile sperm with a tail known as a flagellum, which are known as spermatozoa, while some red algae and fungi produce non-motile sperm cells, known as spermatia. Flowering plants contain non-motile sperm inside pollen, while some more basal plants like ferns and some gymnosperms have motile sperm. Sperm cells form during the process known as spermatogenesis, which in amniotes (reptiles and mammals) takes place in the seminiferous tubules of the testes. This process involves the production of several successive sperm cell precursors, starting with spermatogonia, which differentiate into spermatocytes. The spermatocytes then undergo meiosis, reducing their chromosome number by half, which produces spermatids. The spermatids then mature and, in animals, construct a tail, or fla ...

Donor Sibling Registry
The Donor Sibling Registry is a website and non-profit US organization serving donor offspring, sperm donors, egg donors and other donor conceived people. It was founded in September 2000 by a mother-and-son team, Wendy Kramer and Ryan Kramer of Nederland, Colorado. Purpose and goals The Donor Sibling Registry (DSR) was founded in 2000 to assist individuals conceived as a result of sperm, egg or embryo donation who are seeking to make mutually desired contact with others with whom they share genetic ties. The DSR has pioneered an international discussion about the donor conception industry and the families, with its research, media appearances, speaking engagements, and interviews. The DSR advocates for the right to honesty and transparency for donor-conceived people, for social acceptance and legal rights, and values the diversity of all families. History The DSR began as a Yahoo! group, which was created in September 2000. It was started by Wendy Kramer and her then 10-yea ...

Human Reproduction
Human reproduction is sexual reproduction that results in human fertilization to produce a human offspring. It typically involves sexual intercourse between a sexually mature human male and female. During sexual intercourse, the interaction between the male and female reproductive systems results in fertilization of the ovum by the sperm to form a zygote. These specialized reproductive cells are called gametes, which are created in a process called gametogenesis. While normal cells contain 46 chromosomes (23 pairs), gamete cells only contain 23 single chromosomes, and it is when these two cells merge into one zygote cell that genetic recombination occurs and the new zygote contains 23 chromosomes from each parent, giving it 46 chromosomes (23 pairs). The zygote then undergoes a defined development process that is known as human embryogenesis, and this starts the typical 9-month gestation period that is followed by childbirth. The fertilization of the ovum may be ac ...

Family Law
Family law (also called matrimonial law or the law of domestic relations) is an area of the law that deals with family matters and domestic relations. Overview Subjects that commonly fall under a nation's body of family law include: * Marriage, civil unions, and domestic partnerships: ** Entry into legally recognized spousal and domestic relationships ** The termination of legally recognized family relationships and ancillary matters, including divorce, annulment, property settlements, alimony, child custody and visitation, child support and alimony awards ** Prenuptial and Postnuptial agreements * Adoption: proceedings to adopt a child and, in some cases, an adult. * Surrogacy: the law and process of giving birth as a surrogate mother * Child protective proceedings: court proceedings that may result from state intervention in cases of child abuse and child neglect * Juvenile law: Matters relating to minors including status offenses, delinquency, emancipation and juven ...

Dibling
A dibling, a portmanteau of donor sibling, or donor-conceived sibling, or donor-sperm sibling, is one of two or more individuals who are biologically connected through donated eggs or sperm. The term is not favored among some donor-conceived people, who prefer the use of half-sibling. People born from anonymous or ID release sperm or egg donation are able to find half-siblings conceived using the same gamete donor online through the Donor Sibling Registry or by using commercially-available DNA test kits. DNA testing is more accurate because it relies on comparison of single-nucleotide polymorphisms instead of gamete donor identification numbers (which may be erroneous). See also *Accidental incest *Artificial insemination * Donor conceived person *Sperm bank A sperm bank, semen bank, or cryobank is a facility or enterprise which purchases, stores and sells human semen. The semen is produced and sold by men who are known as sperm donors. The sperm is purchased by or for other pe ...

Accidental Incest
Accidental incest is sexual activity or marriage between persons who were unaware of a family relationship between them which would be considered incestuous. The laws of many jurisdictions void incestuous marriages, even if entered into without awareness of the kinship. If an incestuous relationship is suspected, DNA testing may be used. Some jurisdictions permit offspring of IVF donations access to donation records or to adoption records. Causes People may be unaware of a kinship relationship between them in a number of circumstances. For example, artificial insemination with an anonymous donated sperm may result in offspring being unaware of any biological relations, such as paternity or half siblings. To reduce the likelihood of accidental incest, fertility clinics usually limit the number of times that a donor's sperm may be used. Some countries have laws limiting the number of children a donor can father, while others limit sperm donations based on family numbers to enable ...

Sperm Donation
Sperm donation is the provision by a man of his sperm with the intention that it be used in the artificial insemination or other 'fertility treatment' of a woman or women who are not his sexual partners in order that they may become pregnant by him. Where pregnancies go to full term, the sperm donor will be the biological father of every baby born from his donations. The man is known as a sperm donor and the sperm he provides is known as 'donor sperm' because the intention is that the man will give up all legal rights to any child produced from his sperm, and will not be the legal father. Sperm donation may also be known as 'semen donation'. A man provides his semen but the purpose of the donation is that his gametes contained within the semen, i.e. the sperm cells, be used to provide pregnancies for third parties. Sperm donation enables a man to father a child for third-party women and is therefore categorized as a form of third-party reproduction. The process of inseminating ...

Egg Donor
Egg donation is the process by which a woman donates eggs to enable another woman to conceive as part of an assisted reproduction treatment or for biomedical research. For assisted reproduction purposes, egg donation typically involves in vitro fertilization technology, with the eggs being fertilized in the laboratory; more rarely, unfertilized eggs may be frozen and stored for later use. Egg donation is a third party reproduction as part of assisted reproductive technology. In the United States, the American Society for Reproductive Medicine has issued guidelines for these procedures, and the Food and Drug Administration has a number of guidelines as well. There are boards in countries outside of the US which have the same regulations. However, egg donation agencies in the U.S. can choose whether to abide by the society's regulations or not. History The first child born from egg donation was reported in Australia in 1983. In July 1983, a clinic in Southern California reported ...

DNA Database
A DNA database or DNA databank is a database of DNA profiles which can be used in the analysis of genetic diseases, genetic fingerprinting for criminology, or genetic genealogy. DNA databases may be public or private, the largest ones being national DNA databases. DNA databases are often employed in forensic investigations. When a match is made from a national DNA database to link a crime scene to a person whose DNA profile is stored on a database, that link is often referred to as a ''cold hit''. A cold hit is of particular value in linking a specific person to a crime scene, but is of less evidential value than a DNA match made without the use of a DNA database. Research shows that DNA databases of criminal offenders reduce crime rates. Types Forensic A forensic database is a centralized DNA database for storing DNA profiles of individuals that enables searching and comparing of DNA samples collected from a crime scene against stored profiles. The most important function of ...

Genetic Genealogy
Genetic genealogy is the use of genealogical DNA tests, i.e., DNA profiling and DNA testing, in combination with traditional genealogical methods, to infer genetic relationships between individuals. This application of genetics came to be used by family historians in the 21st century, as DNA tests became affordable. The tests have been promoted by amateur groups, such as surname study groups or regional genealogical groups, as well as research projects such as the Genographic Project. As of 2019, about 30 million people had been tested. As the field developed, the aims of practitioners broadened, with many seeking knowledge of their ancestry beyond the recent centuries, for which traditional pedigrees can be constructed. History The investigation of surnames in genetics can be said to go back to George Darwin, a son of Charles Darwin and Charles' first cousin Emma Darwin. In 1875, George Darwin used surnames to estimate the frequency of first-cousin marriages and calcul ...
