In the new comedy movie, «Delivery Man», which hits theaters today, an anonymous sperm donor played by Vince Vaughn finds out that he has contributed to the birth of 533 children. As this film garners more and more attention, many people are wondering: Can this happen?

Well, in theory, yes. And I’m sure it has happened – though perhaps to a lesser extent – and we just don’t know anything about it.

For years, anonymous sperm donors have been helping women get pregnant.

Most sperm banks monitor or limit donors when they notice that they have produced around 25 children.

However, it can be difficult to monitor the number of children a donor has fathered. While most patients and their delivering physicians should report their pregnancy outcome to the sperm bank after utilizing donor sperm, not all do.

Each year, it is estimated that anywhere from 30,000 to 60,000 children in the United States are born with the help of artificial insemination. Over the years, as sperm donation has increasingly become a public matter, more of the children born from donor sperm are attempting to find their biological fathers.

This movie will open up some broader questions about how we can better regulate this industry.  The film should also raise discussions about just how much information should be available to children born from donors in order for them to better explore their own identity, says dr.Manny Alvarez, Fox News reports.

Sperm donation is something that gives tremendous happiness to couples who truly have a great desire to bring life into this world.
