Female to male transmission of HIV?

I have heard rumors that it is much harder for a male to contract HIV from a female, than vice versa. I was wondering if anyone had statistics on such cases. I had one iffy encounter, and don't honestly think I did contract it. Could anyone explain why it is harder for a male to get it, and if it is harder for a male to contract HIV, how come most the cases of HIV in the u.s.a. are majority male. That doesn't make much sense to me, if it is harder for a male to contract the disease. Any info would be helpful

Actually, this is a pretty straight forward answer (in spite of the other rants on this page)

Yes, it is harder for men to get HIV from women than for women to get it from men.
Men have about 1 in 300 chance per sexual encounter of contracting HIV from a HIV positive women.
Women have about 1 in 150 chance per sexual encounter.

This assumes penis-vagina sex. Anal sex allows for more trauma and small tearing in the mucosa and therefore has a higher rate than penis-vagina sex.

It is equally likely to pass the dreadful HIV virus from a male to a female or vice versa, and also when they belong to the same gender.

Please visit a doctor asap to get tested for HIV, This is the only sure way you can protect yourself and others. Statistics would not help you at all.

Please don't believe this misnomer... though it may be reported by some sources to be statisically harder for men to contract they do contract through unprotected sexual activity with an infected mate all the time. The only way to know for sure is to be tested to put any concerns to rest. I'm not sure about current statistics... best I can recommend is to visit www.aidsonline.com, www.amfar.org or www.aids.org for more accurate information...good luck.

my gynecologist told me that yes it is more difficult for a female to transmit HIV to a male; it is easier for male to female transmission because of two factors one.. the vagina is one "large" mucous membrane, and there are going to be tiny fissures, cuts, and scrapes just from initial penetration, and thus the HIV positive semen has a large ample amount of opportunitiy of getting into the blood stream; and number 2 being that; yes condoms when used properly protect against the spread of hiv correct? 90 something percent or so... well how is it that they are only lower in percent effective against preventing pregnancy? well because there are tiny cracks and microscopic holes in condoms that generally don't pose threat but there is still that chance; hope this helps. and the reason that the most cases of HIV positive in the US is male is generally because men are more apt to have multiple sex partners and not use protection as they should. and no i am not bashing men at all.

All studies do show that to be true. As far as the majority of cases in the US being male...that is false...the majority these days are intraveneous drug users regardless of gender. The male gay community learned all about safe sex in the 1980's and the percentage of gay men with HIV has declined every since.

Semen contains the HIV virus. The vagina is basically a mucus membrane containing many blood vessels. Tearing of the vaginal wall during sex leads to direct blood contact with the HIV infected semen...that is why it is easier for a woman to get HIV from a man than vica versa. For a guy to get HIV from a woman he has to either have a cut somewhere to get blood exposure to the females mucus or participate in high risk activities such as scat eating.

Its less likely to pass HIV from female to male. It is possible tough because vaginal fluids, like semen have one of the highest concentration of the HIV virus parts per million in a given sample. So yes it is possible, but less likely than Male to Female transmission... ALWAYS use a condom!

HIV is not harder to contract from a female. sexually transmitted disease is easy to get. Be careful about your future encounters, since not only can you get HIV or some other serious debilitating disease that will eventually kill you, but you can also get loads of other nasty ones, like chlamydia, gonorrhea, hepatitis C, herpes, human papilloma virus, those last three are permanent buggers, too!
