The movement to compel heterosexual men to embrace their full responsibility for reproductive choices by limiting themselves to ejaculating only when attempting to create a pregnancy.

Jismists believe that ejaculation begins life and therefore they place the burden of birth-control measures and their attendant failures squarely on the shoulders of the possesors of sperm.

Jismism honours men as being more able to control reproduction than women, who have thus far been given the whole responsibility for it and have, judging from unplanned pregnancy rates, failed miserably.

Jismists also recognize that it has been the male of the species which has thus far made all the rules regarding how and when a woman can engage in various birth-control practices and therefore believe it is only right to go the distance and make the rules for themselves for a change.

Motto: Spread the word, not the seed!

Jismism has no religious affiliation.
Under the new Jismism-inspired law, all unwanted pregnancies are deemed to be the fault of the male who ejaculated without intent to reproduce. Under this new law, all care and expenses of raising the child AND compensation for the inconvenience the pregnancy causes the mother; OR the cost and social stigma of the abortion procedure must be borne by the male who failed in his duty.
