At first, Katipunan was purely a patriotic society for men. Owing to the growing suspicion of the women regarding nocturnal absences of their husbands, the reduction of their monthly earnings and "long hours of work", Bonifacio had to bring them into the realms of the KKK. A section for women was established in the society: to become admitted, one must be a wife, a daughter, or a sister of a male "katipunero". It was estimated that from 20 to 50 women had become members of the society.
