I found this article today titled “New Gene Identified that Helps Explain Infertility”.  Read through it and see if it is helpful to you.  Obvious not all causes of infertility would be genetically related but here is an excerpt:

The researchers analyzed hundreds of infertile fruit flies (Drosophila oocytes) for the purpose of their study. Results showed that chromosomes do not huddle together without the gene SRPK, which can be found in mammalian and human cells.

According to the team, the absence of SRPK ultimately leads to sterility and low fertility. This huddling process was also previously studied in mice, which allowed scientists to see that it is a critical process that helps eggs stay fertile.

(Perhaps they chose to study fruit flies because of their notoriously easy reproductive qualities.)

If there is a gene that is related to infertility would you want to be tested to see if you were missing it?  Should all women be tested early in their reproductive years? What do you think?
