It is generally recommended that men are not advised to have children while taking medication, because many drugs have side effects and whether a person can have children while taking medication depends on the nature of the medication he is taking. If the medication taken will not harm the sperm and will not have any negative impact on the sexual organs, it will not affect pregnancy. However, if the medication a man is taking is for the treatment of the kidneys, improving sperm vitality, treating infectious diseases, treating the sexual organs, etc., it is not advisable to have sex before recovering from the disease. If you want to ensure the safety of the next generation, it is best to wait until the drugs in your body are completely metabolized before preparing for pregnancy. Some drugs can even have a negative impact on sperm production and sperm quality, such as tetracyclines, which can lead to increased sperm malformation, decreased sperm viability and prolonged sperm liquefaction time, so try to avoid this situation.
