I cannot create a summary of the requested article because the full text of the article titled "Opinion: U.S. government must invest more in research around men's sexual and reproductive health" is not found in the search results provided. The search results only contain links to various Slovak documents related to reproductive health, sexual violence and gender equality, but not the article itself that you asked to summarize. Without access to the full content of the article, I cannot comply with your request to write only verified facts from it. If you could provide me with the full text of the article or relevant parts of it, I would be happy to create an accurate and factual summary in the format you require.
