In our final episode of Season 2, we explore the science of sperm storage. Sperm storage occurs when sperm viability is maintained outside of the male reproductive tract. This process happens, at least for some time period, naturally in all internally-conceiving animals. Sperm storage is also used by humans for assisted reproduction and fertility preservation. We learn about both processes through interviews with Dr. Teri Orr who studies bat reproduction and Matthew Hudnall who is the director of a sperm bank and a fertility preservation center.
