Researchers are studying whether a particular genetic change in mitochondrial DNA (the energy-producing part of cells) called MT-ND1 m.3700G>A is connected to severe male infertility. This is a retrospective study, meaning researchers are looking back at existing medical records and tissue samples from men with unexplained low or absent sperm production, as well as fertile men for comparison. The goal is to understand if this genetic variant runs in families and whether it affects sperm production.
Many men experience very low or absent sperm production with no clear explanation. Doctors want to know whether genetic changes passed down from mothers through mitochondrial DNA might be responsible for some cases. Understanding this connection could help explain infertility in some men and guide better diagnosis and counseling for affected families.

If you qualify, participation involves allowing researchers to analyze your existing medical records and any tissue or blood samples that were already collected during clinical care. For some participants, family members may also be asked to provide samples or information to help researchers understand inheritance patterns. There are no new treatments given, and no study-related procedures — researchers are simply reviewing what doctors already have on file and examining stored biospecimens.
