To the above posters (2) I could place my answers to your (sometimes ill-informed) comments withi yours which would be best, but I am busy so as a second best refer you to the venomoid FAQ website here:
where all is answered.
The second poster is disingenius when he claims venomoid surgery is not simple. Fact is, to an experienced practitioner it is! Especially as compared to other potential surgeries.
Of course the invasive procedure of probing a snake to determine a snake's sex is simpler, but to allege venomoid surgery is particulary hard is patently false.
