Final answer:
Selection criteria for a semen donor prioritize well-established fertility, good physical health, and a well-built and well-nourished body. Age parameters are also considered, typically ranging from 17 to 75 years. The reception's role is to screen donors to ensure they meet these specific criteria.
Step-by-step explanation:
When selecting a donor for semen collection, there are specific criteria that need to be met to ensure high fertility potential. The donor should be well built, well nourished, and come from a well-established pedigree. This means that the donor must have a proven high degree of fertility, which often includes having sired offspring that are healthy. Additionally, while physical criteria such as height and weight may be considered, they are secondary to factors directly related to fertility, such as sperm quality and genetics.
Age is also a significant factor, and the donor typically needs to fall within certain age parameters, often between 17 to 75 years old, although the acceptable age range could vary depending on different institutions' policies. Other factors like intelligence or fitness may be part of an overall health screening but are not, by themselves, primary criteria for selection in this context. The role of the reception or the donor program is to screen candidates to ensure they meet these criteria, in addition to conducting medical examinations and genetic screenings.
