This work, published online on the website of the journal Mucosal Immunology, could make it possible to test novel HIV/AIDS prevention strategies. http://medicalxpress.com/news/2013-03-sexually-transmitted-hiv-key-mechanisms.html HIV & AIDS Fri, 01 Mar 2013 10:31:04 EST news281356254 A study in Ireland found that women recovering from gynaecological cancer received little advice from healthcare professionals about the effects of the disease on sexuality. This was not as important in initial stages of diagnosis and treatment where patients were dealing with life and death issues.

Parents worry about their kids getting involved in all kinds of risky behavior, but they worry especially about their kids' forays into sexual relationships.
