Institute of Space and Astronautical Science, Japan Aerospace Exploration Agency (JAXA)(ISAS)), Sagamihara, Kanagawa Japan, Effect of gravity on reproduction is an important problem for inhabiting in space. We have been investigating the effect of hyper-gravity on male reproductive systems in mouse and found that male reproduction was not affected by hyper-gravity at least 3G. In this paper, we looked at the effect of tail suspension, as a simulation of micro-gravity, in male mouse. We found that tail suspension caused decrease in the weight of testis and suppressed spermatogenesis. In addition, sperm showed low quality comparing with the ground control and hyper gravity. Further experiments are necessary for evaluating if the tail suspension method is appropriate for a simulation of micro-gravity., 形態: カラー図版あり, Physical characteristics: Original contains color illustrations, 資料番号: AA0065129076}, pages = {203--204}, publisher = {宇宙航空研究開発機構宇宙科学研究所 (JAXA)(ISAS), Institute of Space and Astronautical Science, Japan Aerospace Exploration Agency (JAXA)(ISAS)}, title = {尾部懸垂の精子形成における影響}, volume = {27}, year = {2011} }
