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. 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. However conception is achieved, the nature and course of the pregnancy will be the same as one achieved by sexual intercourse, and the sperm donor will be the biological father of every child born from his donations. Sperm donation enables a man to father a child for third-party women, and is therefore, categorized as a form of third party reproduction.

Semen analysis as an integral part of infertility investigations is taken as a surrogate measure for male fecundity in clinical andrology, male fertility, and pregnancy risk assessments. Clearly, laboratory seminology is still very much in its infancy. In as much as the creation of a conventional semen profile will always represent the foundations of male fertility evaluation, the 5th edition of the World Health Organization WHO manual is a definitive statement on how such assessments should be carried out and how the quality should be controlled.
