Why sex is good for you?

It makes you more fertile and can help you live longer: Why sex is good for you

When it comes to sex, there's no other month like August. Lingerie retailer Ann Summers reported a 40 per cent rise in sales last August as shoppers took advantage of the holiday period to boost their sex lives. Meanwhile, researchers from Boston State Hospital in the U.S. have found that summer sun at least doubles levels of the sex hormone testosterone, boosting a flagging libido. This is thought to be because the sun's rays trigger vitamin D production, which in turn boosts production of the hormone.

And if another excuse is needed, it's well known that sex burns calories ? just this week a survey found that 87 per cent of women named sex as their favourite way to exercise (shopping came second). But there are many other benefits, too. Here some of the country's leading experts reveal some little-known facts about why sex is good for your health.

Sex relaxes the muscles and alleviates neck and shoulder tension, says Dr Arun Ghosh, a GP specialising in sexual health at the Spire Liverpool Hospital. And surprisingly, it might also tell you whether you need glasses. ?I've had patients complain of poor vision after sex. What's happened is that, like all the other muscles in the body, their eye muscles have relaxed and are performing at their true ability, rather than straining and squinting as they would normally.' So if your sight goes blurry after sex, it's worth going for an eye test.

Having sex three times a week could halve the risk of heart attack or stroke Having sex three times a week could halve the risk of heart attack or stroke Sex can have a protective effect on the heart. A study at Queen's University in Belfast found that having sex three times a week could halve the risk of heart attack or stroke. Another study in Israel found that women who had two orgasms a week were up to 30 per cent less likely to have heart disease than those who didn't enjoy sex or didn't orgasm. Dr Lisa Turner, a sex and relationship therapist, says: ?One theory is that these women may have felt depressed, which has been linked with an increased risk of a heart attack. 'The endorphins released during sex also neutralise the stress hormones in the body, which are linked to heart disease.' And the old cliche of sex causing heart attacks? ?It's a very low risk ? it accounts for less than 1 per cent of all deaths,' says Dr Graham Jackson, consultant cardiologist at the London Bridge Hospital and chairman of the Sexual Advice Association. However, if you're over 50, overweight and unfit, there is a risk to your heart ? just as there would be if you suddenly and vigorously took up any form of exercise. ?What also increases the risk is extra-marital affairs, and this has been proven by three large studies,' says Dr Jackson. ?In fact, this accounts for 75 per cent of heart-related deaths from sex, 90 per cent of which are older men. It's thought the combination of high-fat foods and alcohol ? wining and dining ? combined with vigorous exercise, often with a younger partner, is what tends to trigger the heart event.'

U.S. research found menopausal women who had sex every week had oestrogen levels twice as high as their abstaining counterparts. The hormone has a protective effect in bone health and a lack of it after the menopause has been linked with osteoporosis. ?Regular sex increases the production of oestrogen,' says Dr Peter Bowen-Simpkins of the Royal College of Obstetricians and Gynaecologists.

?I'm often asked whether penis length affects fertility and the good news is no,' says Dr Ghosh. But the amount of sex you have is important. The more often you make love, the better quality your sperm will be. ?If you're trying to conceive, you need the sperm to be as fresh as possible ? not stuff that's been sitting in the prostate for three or four days,' he adds.

Researchers at Nottingham University have found that men who enjoy a regular sex life in their 50s are at lower risk of developing prostate cancer. ?Clearing the prostate out regularly is the reason behind this,' says Dr Ghosh. ?The link was suggested after research showed that monks appear to have a higher chance of developing prostate cancer.'

Here's a simple way to get your man to kick his smoking habit ? remind him that it causes the penis to shrink and can cause impotence. Erections are all about good blood flow, and lighting up worsens blood flow to the spongy tissues in the penis, says Raj Persad, consultant urological surgeon at Bristol Royal Infirmary. ?As a result, they become starved of oxygen and the delicate cells die away. They then become fibrotic ? forming scar tissue ? which is less elastic and less able to expand during an erection than regular healthy tissue.' Smoking is also a known cause of erectile dysfunction as it causes hardening of the arteries and hampers good blood flow. A study of more 7,000 Chinese men, published in the American Journal of Epidemiology, found that the more cigarettes smoked a day, the higher the risk of impotence.
