Somatostatin is present in high concentrations in human seminal plasma. Semen was obtained from men with spinal cord injury by vibratory-and/or electrostimulation. The seminal somatostatin concentration and sperm motility rate depended on the location of the spinal cord lesion. In men with lesions at or above T6 the seminal plasma concentration was significantly decreased compared to healthy men and to patients with lesions below T6 (P < 0.005). The latter group did not differ from healthy men. Men with spinal cord lesions below T6 had significantly decreased sperm motility rates (P = 0.09) compared to patients with lesions at or above T6. Seminal somatostatin concentrations were similar in vibratory- and electrostimulated ejaculates. The seminal somatostatin concentration, semen volume, sperm count, motility and morphology in each patient was not affected when repeated vibratory ejaculations were performed at home.
生长抑素在人类精浆中含量很高。通过振动和/或电刺激从脊髓损伤男性获取精液。精浆中生长抑素浓度和精子活力率取决于脊髓损伤的位置。与健康男性以及T6以下损伤患者相比，T6及以上损伤男性的精浆浓度显著降低（P < 0.005）。后一组与健康男性无差异。与T6及以上损伤患者相比，T6以下脊髓损伤男性的精子活力率显著降低（P = 0.09）。振动射精和电刺激射精的精浆生长抑素浓度相似。在家中进行重复振动射精时，每位患者的精浆生长抑素浓度、精液量、精子计数、活力和形态均未受影响。
