DNA Testing for Beaver Sexing

At chXout we carry out beaver sexing through DNA analyses of fur samples.

Our beaver sexing service will provide you with accurate and fast results to aid monitoring, re-introductions and ex situ conservation breeding programmes. 

Beavers are monotypic in nature and lack obvious anatomical features for sex identification (except lactating females). Using traditional field methods can be difficult and timely, making sex determination of beavers challenging.


DNA testing for sex determination can improve the accuracy of sexing when the correct determination of gender is essential. DNA analyses for sex identification is also helpful when intact specimens are not available, trapping individuals is not feasible, or projects span large areas.

We use PCR based techniques to amplify selective regions of the X or Y chromosomes to differentiate sexes with high accuracy.

About The Eurasian Beaver

The Eurasian beaver (Castor fiber) is native to the UK and used to be widespread across England, Wales and Scotland. They were hunted to extinction in the UK by the 16th century, for their fur, meat and castoreum which was used in perfumes, food and medicine.

Over the past decade major efforts have been underway to reintroduce beavers into the British countryside. As a result, the Eurasian beaver has shown good recovery across much of its range.

Beavers are now a legally protected species in Scotland. However, they are yet to receive legal protection in England in Wales where they are still threatened by human-wildlife conflict, as well as habitat loss and degradation.

Though the Eurasian beaver appears on the International Union for Conservation of Nature Red List of threatened species, categorised as “Least Concern”, conservation efforts are recommended to ensure this species does not become endangered again.

If current trends continue, we hope the Eurasian beaver will once again be a fairly common mammal in Europe within the next few decades.

If you would like to determine the sex of a Eurasian beaver, you can make use of our fast and professional beaver sexing service today.
