Today is the first burst of the most bizarre news: According to the "Archives of Sexual Behavior," the research report, without using a condom sex (including oral sex) may be beneficial for women's health physical and psychological.
The researchers invited 293 women to fill in two questionnaires: a questionnaire to measure the details of their sex life, another questionnaire analysis of their psychological traits. After that, the researchers measured the women's blood in the seminal plasma content (translation: checked the information on whether the absorption of semen in the female vagina controversy was that women can not absorb the semen, slowly excreted some people think. semen inside the vagina can absorb, for women have certain health effects, according to the study of neurochemicals, semen contains, apparently through vaginal penetration into the capillary blood of women. the study also noted that there are also oral sex kinds of action, these chemicals are also evident through the capillaries oral penetration.), and compared with survey data. It was found that women often do not use condoms exhibit depressive symptoms, significantly less than women who often or always use condoms.
