They were not giving advice. they were mocking men and dismissing male loneliness as a non-issue.
I don’t know the solution for loneliness specifically, but hatred towards men for being virgins or being unsuccessful with women will only exacerbate the issue.
What doesn’t get mentioned about the clinical trials is that some of the men were infertile for a few years after they stopped taking birth control and in one case, he was rendered permanently infertile. Some cases resulted in low sperm count as well.
