Should men abstain from sex before fertility treatment?

New research by Israeli fertility experts has challenged current medical opinion, which holds that refraining from sex for up to a week at least is beneficial for men prior to undergoing some types of fertility treatment. Doctors and scientists from Soroka University and Ben-Gurion University of the Negev, Beer-Sheva, tested over 7,200 semen samples for semen volume, sperm concentration and shape, and the percentage and total count of motile (active and moving) sperm. The samples were from around 6,000 men being investigated or treated for infertility who had abstained from sex for periods up to two weeks.

Men, women both crazy jealous

Men are from Mars and women are from Venus, or so we’ve been told, and when it comes to jealousy this is especially true. Men, psychologists have long contended, tend to care more about sexual infidelity while women usually react more strongly to emotional infidelity. This view has long been espoused by evolutionary psychologists who attribute these gender differences to natural selection, which, they say, encouraged the sexes to develop different emotional reactions to jealousy. However, a recent research paper published in Personality and Social Psychology Review by Christine Harris, a psychologist with the Center for Brain and Cognition at the University of California, San Diego, casts serious doubts on this view of gender differences on jealousy and argues that more men and women appear to view sexual and emotional jealousy in the same light.

Young gay males are anxious, depressed and ignorant of HIV status

An alarming number of young gay men appear to be highly anxious and depressed, expressing high levels of self-hatred and low self-esteem, according to new research funded by the ESRC. And whilst they are aware of health warnings, the majority have had unprotected sex and few know their current HIV/AIDS status, says the study led by Dr Debra Bekerian of the University of East London’s School of Psychology. Based on preliminary analyses, the report also suggests that young gays who claim to have been traumatised in the past, perhaps through loss of a friend, abuse or violence, are less likely to engage in unsafe sexual practices once they know their current HIV status.

HIV-positive inmates say often have unprotected sex before, after release

Inmates infected with HIV, the virus that causes AIDS, engaged in unprotected sex both before imprisonment and after their release at “exceedingly high rates,” according to a new University of North Carolina at Chapel Hill School of Medicine study. Seventy-eight percent of N.C. men and women prisoners carrying the virus who had a main sex partner reported unprotected sex with that person in the year before they were locked up, the study showed. Twenty-six percent of them interviewed again soon after release admitted to already having sex without condoms with their main sex partners.
