Hormone Replacement Therapy

Hormone Replacement Therapy (HRT) is a medical treatment that involves the use of synthetic hormones to replace the natural hormones that the body no longer produces in sufficient amounts. In the context of space and astronautical engineering, HRT is used to mitigate the negative effects of spaceflight on the human body, particularly in female astronauts. Spaceflight can cause a decrease in bone density, muscle mass, and cardiovascular function, as well as an increase in radiation exposure. HRT can help to maintain bone density, muscle mass, and cardiovascular function, and may also reduce the risk of certain cancers. However, HRT is not without risks, and its use must be carefully monitored to avoid potential side effects such as blood clots and breast cancer.
