Artificial insemination is indeed a boon to many and its growing popularity has also led to a lack of regulation and control in the way fertility clinics and sperm banks operate with no limit on the number of children born from a single sperm donor. Innumerable children born from a single sperm donor can lead to a whole lot of problems, like the spread of rare genetic diseases in the population. Many children born from this process are finding that they have dozens of half-siblings in the world.
Indiscriminate use of sperms from popular donors without any control is a serious issue.
It is important that families be informed about the number of children conceived using the sperms from a single donor.
