I've once written a detailed answer on this one. As far as I remember, out of 8, 5 were pregnancy/women's issues related and 3 were genuine bias and basically - discrimination.
Let me find it...
Edit:
...but if you look at it, some really are female-specific, and are mostly related to pregnancy so it's reasonable to restrict them from men, while other are plain discriminatory and misandric.
Of the eight (all of which are listed on the web page linked below), I find the following, more or less, discriminatory:
http://www.healthcare.gov/news/factsheets/2011/08/womensprevention08012011a.html
1.)"HPV DNA testing: Women who are 30 or older will have access to high-risk human papillomavirus (HPV) DNA testing every three years, regardless of Pap smear results"
My comment: though HPV DNA testing for men hasn't even been developed yet, other forms of diagnosing HPV in men do exist, and since men get HPV as well (and it's as common as it's with women) restricting it from men is definitely discriminatory.
2.)"STI counseling: Sexually-active women will have access to annual counseling on sexually transmitted infections (STIs)."
My comment: ...all the while STI counseling will only be available to men "at higher risk", whatever that means.
3.)"HIV screening and counseling: Sexually-active women will have access to annual counseling on HIV."
My comment: ...while for men only the screening is available, not the counseling. Given the number of men who get the virus each year, such a restriction is unreasonable and, of course, discriminatory.
4.)"Interpersonal and domestic violence screening and counseling: Screening and counseling for interpersonal and domestic violence should be provided for all adolescent and adult women."
My comment: Not available to men at all. Given that men are victims of domestic violence as well, which is probably best proven by the fact that men represent 38-41% of victims in spouse murders, this is again, discriminatory and even misandric.
To address the issue why, I believe, men are (discriminatively) excluded from the above listed services.
It's a simple issue really. You have insurance companies' lobbyists on one side (who want to cover as little as possible, to have the highest profit possible), women's groups lobbyists on the other side, and in the middle you have politicians who have to determine what to do to get elected yet again.
It's a compromise really, they'll pass some of these privileges for women into law to appease the feminists/women's groups thus getting the "women's vote" (or at least, a significant part of it), at the same time not pissing of the insurance companies too much, who will thank them by continuing to donate money to their campaigns.
Men, as a group, simply don't have groups lobbying in their interests as women do in the form of feminist/women's groups. That's the reason for this and any other law that is discriminatory towards men, that gets passed.
Edit2:
"In fact, those are all health issues that have always been covered by health care insurance."
This is obviously false, dark eyes, otherwise they wouldn't say the following...
"The eight new ADDITIONAL WOMEN'S preventive services that will be covered without cost-sharing requirements include...(then they list the 8 points)"
and
"New private health plans must cover the guidelines on women’s preventive services with no cost sharing in plan years starting on or after August 1, 2012."
