Masturbating may protect against prostate cancer

will make you go blind. It will make your palms grow hairy. Such myths about masturbation are largely a thing of the past. But the latest research has even better news for young men: frequent self-pleasuring could protect against the most common kind of cancer.
A team in Australia led by Graham Giles of The Cancer Council Victoria in Melbourne asked 1079 men with prostate cancer to fill in a questionnaire detailing their sexual habits, and compared their responses with those of 1259 healthy men of the same age. The team concludes that the more men ejaculate between the ages of 20 and 50, the less likely they are to develop prostate cancer.
The protective effect is greatest while men are in their twenties: those who had ejaculated more than five times per week in their twenties, for instance, were one-third less likely to develop aggressive prostate cancer later in life (
BJU International, vol 92, p 211).
The results contradict those of previous studies, which have suggested that having had many sexual partners, or a high frequency of sexual activity, increases the risk of prostate cancer by up to 40 per cent. The key difference is that these earlier studies defined sexual activity as sexual intercourse, whereas the latest study focused on the number of ejaculations, whether or not intercourse was involved.
The team speculates that infections caused by intercourse may increase the risk of prostate cancer. "Had we been able to remove ejaculations associated with sexual intercourse, there should have been an even stronger protective effect of other ejaculations," they suggest. "Men have many ways of using their prostate which do not involve women or other men," Giles adds.
Macho exaggeration
Giles accepts the possibility that the men who completed the questionnaires could have lied about their habits. But he doubts this skewed the results, since questions about masturbation are unlikely to evoke the same macho exaggeration as questions about, say, number of sexual partners.
But why should ejaculating more often cut the risk of prostate cancer? The team speculates that ejaculation prevents carcinogens building up in the gland. The prostate, together with the seminal vesicles, secretes the bulk of the fluid in semen, which is rich in substances such as potassium, zinc, fructose and citric acid.
Generating the fluid involves concentrating these components from the bloodstream up to 600-fold - and this could be where the trouble starts. Studies in dogs show that carcinogens such as 3-methylcholanthrene, found in cigarette smoke, are also concentrated in prostate fluid.
"It's a prostatic stagnation hypothesis," says Giles. "The more you flush the ducts out, the less there is to hang around and damage the cells that line them."
Sexual repertoire
His findings suggest an intriguing parallel between prostate cancer and breast cancer, as recent studies indicate that lactating reduces a woman's risk of breast cancer, perhaps because this also flushes out carcinogens. Alternatively, ejaculation might induce prostate cells to mature fully, making them less susceptible to carcinogens.
"All these mechanisms are totally speculative," cautions breast cancer expert Loren Lipworth of the International Epidemiology Institute in Rockville, Maryland.
But if the finding is confirmed, future health advice from doctors may no longer be restricted to diet and exercise. "Masturbation is part of people's sexual repertoire," says Anthony Smith, deputy director of the Australian Research Centre in Sex, Health and Society at La Trobe University in Melbourne.
"If these findings hold up, then it's perfectly reasonable that men should be encouraged to masturbate," he says.

What Your Doctor May Say
In general, the medical community considers masturbation to be a normal part of human sexuality, as long as it is not practiced excessively or under inappropriate circumstances. If you are an adult, your doctor probably will not ask you about masturbation unless you bring up the subject. This is because masturbation is a form of normal sexual behavior, and it is not usually a symptom of illness. In adult patients, doctors usually see masturbation as a healthy, acceptable way to relieve sexual tension, especially when a patient's sexual partner is ill, absent, or otherwise uninterested in regular sexual contact. The National Institute on Aging emphasizes that masturbation actually "can help unmarried, widowed or divorced people and those whose partners are ill or away."

Sexual benefits
Some of the known sexual health benefits of masturbation include:
- Solo masturbation is a safe sex practice that carries no risk of sexually transmitted infection and unwanted pregnancy. As part of lovemaking between two people, it is known as 'mutual masturbation'.
- Sexual tension is released. Masturbation allows a person to express their sexuality by themselves and is valuable if, for example, they don't have a partner or if sex with their partner isn't available, or if they want to (or have to) abstain from sex for any reason.
- Being familiar with your own sexual responses allows you to better communicate your wants and needs to your partner.
- Masturbation is a popular treatment for sexual dysfunction; for example, women who don't orgasm can learn by masturbating. Men who suffer from premature ejaculation can use masturbation to practice control.
Health benefits
Some of the known health benefits of masturbation include:
- Eases some of the symptoms of premenstrual syndrome
- Relief from menstrual cramps
- Muscle relaxation
- Helps you to fall asleep
- Promotes release of the brain's opioid-like neurotransmitters (endorphins), which cause feelings of physical and mental wellbeing
- Reduces stress
- Enhances self-esteem.
Masturbation in young children
Boys generally start masturbating at an earlier age than girls, since the clitoris and vagina are harder to find than the penis. Studies show that the way in which parents react to their child's masturbation impacts on the child's sexual attitudes and behaviours in adult life. Suggestions for parents include:
- Young children masturbate for various reasons, including curiosity, exploration and sensory pleasure.
- Reassure yourself that masturbation in young children is normal. It is not a sign of sexual deviancy.
- Focus on the setting, rather than the activity itself. For example, if your child is masturbating in public, tell them that what they're doing is fine if they do it in private, much like toileting and picking one's nose are private activities.
- Young children may turn to masturbation in times of stress. If your child is masturbating to the point where playtime and other activities are curtailed, you need to find out what is making them anxious and upset.
- If you are concerned about your child's masturbatory practices, consult with your doctor or paediatrician.
