The Gom Jabbar (or "High-Handed Enemy") is merely the hollowed out poison needle worn on a Sister's finger. It is used because it is easily concealed and produces rapid, lethal results (using "meta-cyanide", according to The Dune Encyclopedia). The Gom Jabbar is used alongside a nerve-induction device contained in a box during a test of "crisis and observation". A "Human" can control pain enough to conquer animal instinct. Failure of this awareness test results in being pricked by the closely held weapon.
Men do get attacked with them: Baron Harkonnen was fatally stabbed with the Gom Jabbar by Alia before being consumed by a sandworm.
The Human Awareness test is used when considering recruits for the Sisterhood, and so is not normally something men are eligible for. Mohiam was using the test on Paul to determine if he was an Abomination, if not an animal or a Human. The use of the test amongst Fremen was due to the isolated development (physically and temporally) of Bene Gesserit religious indoctrination on Arrakis. Similar unique developments occurred famously with the Honoured Matres and their practice of sexual imprinting.
