Guest Room is a short film Written & Directed by Joshua Tate and starring Lauren Potter (“Glee”) and Michael Iovine.  It won the Audience Award (Competition Short) at SXSW 2015.

I think you are going to love this movie.  It’s beautiful, emotional, and honest.  I could easily see this being used in a human sexuality classroom to help discuss parenting, consent, and support from families.  It follows the story of a young couple who are faced in a situation many young couples find themselves in, an unexpected pregnancy.  Like many young couples, the response of their families  is shock and disappointment and this makes it difficult to determine their own feelings, hopes, and wants.

There was one statistic that was mentioned in the film that I had not heard before.  It said that a women with Down Syndrome has a 50% chance of having a child with Down Syndrome.  I did a little digging to see if I could find out more and received some help from The Tech Geneticist a  project from the University of Stanford which seeks to increase the public understanding of genetics.  About half of the eggs of a women with Down Syndrome will have an extra 21st chromosome (similar to what is described in this post http://genetics.thetech.org/ask/ask296).  Her actual chance of having a child with Down Syndrome is less than 50% because fetuses with extra 21st chromosomes are at increased risk of complications.  According to the National Down Syndrome Society only about 50% of women with Down Syndrome are fertile (ovulate).

It’s trickier when it comes to thinking about the father.  Much less is known about the heritability (chance of passing a genetic trait on) of Down Syndrome for men with Down Syndrome, but it may be that their sperm that carry two 21st chromosomes would be less viable than their sperm that only have one.  Both the Tech Geneticist and the National Down Syndrome Society suggested men with Down Syndrome seem to have much lower fertility rates than their same age peers with two 21st chromosomes.
