Effect of Spaceflight Factors on the Reproductive System

At this point of time, effects of spaceflight factors on the male and, particularly, female reproductive systems are actually poorly known. This is because of, likely, low probability that the systems will develop life-threatening pathologies. Importance of this topic grows gradually with extension of mission duration and, on a number of occasions, age of cosmonauts; in great part, healthy aging depends on functioning of the reproductive system. Remote space exploration in future will raise the concern about reproductive health after return from missions beyond Earth’s magnetosphere. The review presents the up-to-date data about the effects of spaceflight factors on the reproductive organs and generative cells of various animal species and the human.
