Application of a vibrator of 80 Hz and 2.5 mm amplitude to the lower surface of the glans penis caused ejaculation in less than 20 minutes (usually less than 3 minutes) in 48 of 81 men with spinal cord injuries (mostly complete) of more than 6 months duration. It failed in all the 19 of the 81 who lacked reflex hip flexion on scratching the soles of the feet, and in 14 others. It failed in 11 of 12 men with injuries of less than 6 months' duration. From 21 of 34 men for whom the vibrator failed, semen could be obtained by electroejaculation, which is just as successful within 6 months of injury as subsequently and may succeed even if reflex hip flexion is absent. Eleven pregnancies where the father had a complete or nearly complete spinal cord lesion are reported. Nine healthy children have been born.
对81名脊髓损伤（大多为完全性损伤）超过6个月的男性，将频率80赫兹、振幅2.5毫米的振动器置于阴茎头下表面，48人在不到20分钟（通常不到3分钟）内射精。81人中，19人在搔抓足底时缺乏反射性髋部屈曲，另外14人，振动器刺激均未成功。12名损伤时间不到6个月的男性中，11人刺激失败。34名使用振动器刺激失败的男性中，21人可通过电射精获取精液，损伤后6个月内进行电射精与之后进行同样成功，即使没有反射性髋部屈曲也可能成功。报告了11例父亲患有完全性或近乎完全性脊髓损伤的妊娠情况。已出生9名健康儿童。
