Human males do not naturally possess wombs to gestate offspring. Drilled holes in the hotel materials also encourage insects to leave larvae to gestate. Porpoises and blue whales gestate for about 11 months. Depending on temperature, eggs may gestate for one to three weeks. Females gestate during the dry season, from May through September, when resources are low. The new strain allows an extraterrestrial to gestate inside the host within 96 hours.
