Researchers have recently discovered a new method to create viable frog sperm from frozen tissue samples! It’s a breakthrough that could help us better understand the reproductive biology of amphibians, and also potentially help us conserve species that are threatened or endangered. The process involves thawing the tissue samples, isolating the sperm cells, and then using a process called “capacitation” to make the sperm cells strong swimmers. The researchers tested the process on two frog species, the European common frog and the common midwife toad, and were successful in producing viable sperm from both species. This could lead to the development of new conservation strategies for these species, and potentially others.
