What is the gender ratio in cryonics ?
Two-thirds to three-fifths of signed-up cryonicists are male. But at the Cryonics Institute, the majority of cryonics patients are female, because of the number of sons who cryopreserve their mothers. Cryopreservation of parents is much less frequent at Alcor. Although there are female cryonics activists, the problem of a cryonics activist husband and an anti-cryonics wife has been the subject of frequent concern. See The Hostile Wife Phenomenon in Cryonics.
