Richard Kieckhefer in European Witch Trials: Their Foundations in Popular and Learned Culture, 1300-1500 surveyed all extant published records of witch trials in England, German, France, Switzerland, Belgium, Holland, Italy^1 for 14^th and 15^th centuries. I've listed the 15^th centuries entries for England below with citations removed.
Men certainly show up in the trials. We can't say how 'easy' it would have been for any gender to be accused (and tried) of witchcraft - the records are incomplete; and we don't know how incomplete they are.
Presented with this list, it would be easy to draw a conclusion that 'attacks' in government and monarchy through sorcery abound; this would be a bias from the sources because royal records having a better chance of survival over 500 years. We could also look at regional patterns; again, a bias from records of certain township archives surviving for whatever reason.
Measured against the multimillion population of England at the time, we see witchcraft accusations being an absolute rarity regardless of gender.
But, we can see that men do feature here far more than they did in the 16^th to 18^th centuries of the early modern period, where there was a significant shift in gender bias in witch trials. Kieckhefer draws attention to the 'political and ecclesiastical character' of the records of the late medieval era - not only in England but across western Europe - and certainly for this reason alone we would see greater inclusion of men. The early modern era sees a shift in gender which emphasizes a turn towards accusations of neighbour against neighbour (see Robin Briggs^2 )
