From what I remember I think globally that’s it is/was closer to (just under) 2:1 on the male v female successful suicides. I also believe that women think about it more and attempt it more often but with less success overall. One giant caveat is that there are many places where “she killed herself” is accepted and never investigated so it’s possible a (large) number of murders are improperly counted as female suicide. (Looking especially at you, “cultures” with “honour” killings)
