When it comes to the topic of infertility, the word "makes infertile" can be quite intense and heavy. Therefore, it may be helpful to have some synonyms on hand to express the same idea in a less direct manner. Some alternative phrasing may include "reduces fertility", "impairs reproductive function", "results in sterility", "renders incapable of reproduction", or "causes a decrease in fertility". It is always important to consider the tone and impact of the words we use, particularly when discussing sensitive issues like infertility. Using synonyms can help us communicate our message with greater sensitivity and respect for those affected by infertility.
