Having sex every day improves the quality of men’s sperm and is recommended for couples trying to conceive, according to new research.

Until now doctors have debated whether or not men should refrain from sex for a few days before attempting to conceive with their partner to improve the chance of pregnancy.

But a new study by Dr David Greening of Sydney IVF, an Australian center for infertility and in vitro fertilisation (IVF) treatment, suggests abstinence is not the right approach.

He studied 118 men with above-average sperm DNA damage and found the quality of their sperm increased significantly after they were told to ejaculate daily for seven days.

On average, their DNA fragmentation index — a measure of sperm damage — fell to 26 percent from 34 percent, Greening told the European Society of Human Reproduction and Embryology in Amsterdam on Tuesday.

Frequent sex does decrease semen volume but for most men this is not a problem.

“It seems safe to conclude that couples with relatively normal semen parameters should have sex daily for up to a week before the ovulation date,” he said in a statement.

“In the context of assisted reproduction, this simple treatment may assist in improving sperm quality and ultimately achieving a pregnancy.”

Greening said it was likely frequent ejaculation improved the quality of sperm by reducing the length of time they were exposed to potentially damaging molecules called reactive oxygen species in the testicular ducts.

Men are much more likely to seek and have casual sex than women, and are far less choosy about the looks of their sex partners.

That’s the conclusion of a new study by British researchers who analyzed questionnaire responses from 860 American, German and Italian students.

The students were asked to imagine being approached by a member of the opposite sex, described as either “slightly unattractive,” “moderately attractive” or “exceptionally attractive.” The participants were then asked what their response would be if such members of the opposite sex offered to go out, go to their apartment, and to go to bed with them.

The 427 men were more likely than the 433 women to agree to casual sex, and the men expressed a greater desire for it than women. The study also found that the men were more likely to go out, go to the apartment, and go to bed with members of the opposite sex in all three categories of attractiveness.

Men needed to be exceptionally attractive to tempt women to consider casual sex, said Dr. Achim Schutzwohl, of the department of psychology at the University of Brunel in the U.K., and colleagues.

German men were less likely to accept date, apartment and sex offers than Italian and American men. Italian men were more likely than Americans to accept an offer of sex.

“While men are not entirely insensitive to their requestor’s attractiveness, women have higher standards and are more likely to engage in casual sex with an exceptionally attractive man than with a less attractive man,” the researchers concluded.

Gays, lesbians and bisexuals are about twice as likely as heterosexuals to seek treatment for mental health issues or substance abuse, a U.S. study finds.

Researchers analyzed data from 2,074 people who took part in the large-scale California Health Interview Survey and found that 48.5 percent of gays, lesbians, bisexuals reported receiving mental health or substance abuse treatment in the past year, compared to 22.5 percent of heterosexuals.

The study also found that lesbian and bisexual women were most likely to receive treatment while heterosexual men were least likely.

“It is well known that health services utilization is greater among women generally. Here we have shown that minority sexual orientation is also an important consideration. Lesbians and bisexual women appear to be approximately twice as likely as heterosexual women to report having received recent treatment for mental health or substance use disorders,” study author Susan Cochran said in a news release.

Greater exposure to discrimination, violence and other stressful life events may explain why gays, lesbians and bisexuals are more likely to seek treatment for these disorders, she said.

“The pervasive and historically rooted societal pathologizing of homosexuality may contribute to this propensity for treatment by construing homosexuality and issues associated with it as mental health problems,” Cochran said.
