Safe sex, it seems, has gotten a bad rap, with one recent survey showing that a quarter of young men and women consider sex with a condom a "hassle." But there's hope yet, as other new research finds safe sex can be fun.The new study of male condom users finds that certain factors, including a partner's comfort, are linked with sexual pleasure during condom use. The results could help sex educators encourage safe sex, said study researcher Devon Hensel, a professor of adolescent medicine at the Indiana University School of Medicine."The number one take-home message is that safe sex can be pleasurable sex," Hensel said. "The idea that using a condom somehow decreases the fun you have when you have sex is completely a misconception."Beliefs about safe sexA survey released last week by the reproductive health research institute Guttmacher revealed that negative attitudes toward condoms are relatively widespread. Researchers conducted phone surveys with a nationally representative sample … [Read more...] about Study: Safe Sex Can Be Fun
Americans are in the dark about a virus linked to cervical cancer that can kill them, two new studies suggest.A vaccine exists to protect against types of the virus, called human papillomaviruses (HPV). But when presented under the umbrella of sexually-transmitted-disease protection, women are less likely to get vaccinated.Every year in the United States, about 6.2 million people get HPV. Anyone who has ever had genital contact with another person can get HPV. Both men and women can get it — and pass it on to their sex partners — without even realizing it.The studies were presented today at the American Association for Cancer Research's Frontiers in Cancer Prevention Research meeting in Boston.Public awarenessThe National Cancer Institute (NCI) analyzed data collected from 3,000 women ranging from 18 to 75 in age.Only 40 percent of the women had ever heard about the virus.Fewer than half of the participants knew of the link between the virus and cervical cancer.64 percent … [Read more...] about Women Unaware Cervical Cancer Caused by Virus
Women who are genetically predisposed to breast cancer, such as actress Angelina Jolie, face a difficult dilemma in terms of their options, experts say.In a New York Times Op-Ed article, Jolie revealed today (May 14) that she had a double mastectomy to prevent breast cancer. Jolie said she carries a mutation in the BRCA1 gene, which significantly increases her risk of developing the disease.For those with BRCA gene mutations, deciding what to do can have psychological and financial implications, and affect family members as well as the patient, said Dr. Myra Barginear, a breast medical oncologist at the Cancer Institute of North Shore Long Island Jewish Health Systems in New York.Ultimately, the decision is an individual one made by a woman in consultation with her doctor, Barginear said. Factors such as a woman's family history of the disease, and whether she has had children can sometimes play a role in her choice, she said. Jolie's mother died of breast cancer at age 56.According to … [Read more...] about Angelina Jolie & Breast Cancer: What Options Do High-Risk Women Have?
Women who freeze their eggs in hopes of improving their fertility later in life feel positive about the experience, but wish they had done it at an earlier age, a new study finds."Egg banking" — the practice of freezing eggs to circumvent age-related infertility — is becoming common in many countries, according to the researchers. Women may freeze their eggs for medical reasons, such as cancer treatment that may affect their fertility, but the new study involved women who underwent the procedure for social reasons, such as wanting to delay childbearing until they found the right partner, or until later in life.While many women in the study said they did not expect they would ever have to actually use their frozen eggs, most also said they would do it again, according to the study, which was presented today (July 9) at the European Society of Human Reproduction and Embryology in Belgium.
