The Effects of Microgravity on Human Sperm


Brief description of study

It has been described that microgravity affects cellular and molecular structures. Cell membrane, cytoskeleton, cytoplasm and nucleus have been found to be sensible to gravitational changes. Alterations in the male and female reproductive systems have also been reported in mouse and other animals. The effects of microgravity on human reproductive cells remain unknown.

The main objective of this experimental study is to investigate the effect of simulated microgravity in human male reproductive cells under in vitro conditions. Induced microgravity conditions will be obtained with a smaller single-engine aerobatic aircraft that can provide parabolic flights.

The main parameters to be analyzed are: sperm motility, vitality, DNA fragmentation and apoptosis.
