Os benefícios de manter relações sexuais de forma regular são amplamente noticiados. Agora sabe-se que a atividade sexual regular pode também prevenir doenças de coração. Mas só nos homens, de acordo com o Daily Mail.
Um novo estudo indicou que fazer sexo várias vezes por semana pode diminuir os níveis de homocisteína, um químico prejudicial que se encontra no sangue e que pode espoletar problemas cardíacos.
Acredita-se que atividade sexual frequente nos homens melhora a sua circulação sanguínea e torna os vasos sanguíneos mais saudáveis, o que é crucial para prevenir a acumulação de homocisteína.
As mulheres, dizem os cientistas, beneficiam muito menos nesta situação porque a excitação sexual feminina é menos dependente de uma circulação sanguínea saudável, um fator determinante para manter a homocisteína controlada.

Sex prevents heart disease – but only in men: Making love can protect the heart from a dangerous chemical in the blood, study finds
- Study shows making love several times a week can cut levels of homocysteine
- This is a harmful chemical in the blood which can trigger cardiac problems
- Benefits women less because sexual arousal isn't as dependent on blood flow
- Researchers called on doctors to advise at-risk male patients to have more sex
Regular sex really is the best medicine for preventing life-threatening heart disease – if you're a man, scientists have found.
New research shows making love several times a week can slash levels of homocysteine, a harmful chemical in the blood which can trigger cardiac problems.
It's thought men getting sex often have better circulation and healthier blood vessels. This is crucial for preventing a build-up of homocysteine.
But scientists say women benefit much less because sexual arousal is less dependent on having a healthy blood flow, which is a key factor in keeping homocysteine under control.
Researchers behind the study called on doctors to advise male patients at risk of heart disease to have more sex.

Britain's biggest killer
Every year, around 73,000 people in Britain die from coronary heart disease. It remains the country's biggest killer.
Doctors have suspected for years that frequent sex can reduce the risks.
One previous study found intercourse twice a week halved a man's chances of clogged arteries compared to those indulging less than once a month.
But there has been little scientific evidence to explain why a healthy sex life protects against illness.
The latest findings, published in the Journal of Sexual Medicine, are the first to show it works by driving down homocysteine levels.
What is the chemical?
The chemical is a vital building block of proteins and occurs naturally in the body.
But excess levels, which can be caused by poor diet, are thought to damage blood vessels supplying the heart - raising the risk of a deadly clot forming.
A major review of scientific data in 2015 found raised homocysteine levels increased the risk of death from heart disease by 66 per cent.
And last year experts at Boston University discovered the chances of a stroke jumped by almost a third in those with high readings. It has also been linked with Alzheimer's disease and cancer.

How was the study carried out?
Researchers from the National Defence Medical Centre in Taiwan tracked more than 2,000 men and women, aged from 20 to 59.
They analysed blood samples to measure levels of homocysteine and matched the results up with volunteers' sexual activity.
The results showed the lowest traces of the chemical were found in men claiming to have sex at least twice a week, while the highest readings were found in those restricted to less than once a month.
But in women there was no significant variation.
First study of its kind
In a report on their findings they said: 'This is the first study of its kind to evaluate the correlation between sexual frequency and homocysteine levels.
'A good quality sex life, frequent sex and libido are all related to health in the middle-aged and elderly.
'Increased sexual frequency could have a protective effect on general health and quality of life - especially in men – so doctors should support patients' sexual activity.'
'Interesting result'
Dr Mike Knapton from the British Heart Foundation said the study produced an 'interesting result' but did not prove regular sex reduced homocysteine levels.
He said: 'A relationship does exist between sex and heart disease risk.
'Checking your blood pressure and cholesterol, as well as keeping active and not smoking, remain the best ways to ensure a healthy future.'
THE BENEFITS OF SEX
Many people worry about the impact their sexual experiences may have on their health.
From STIs to unexpected pregnancies, regular sex can come at a cost.
Yet, spending time between the sheets can also seriously boost our wellbeing from strengthening our immune systems to lowering blood pressure and even giving our memories a boost.
Here are 10 proven benefits of regularly making love:
1. A stronger immune system
2. Better heart health
3. Lower blood pressure
4. Natural pain relief
5. A reduced risk of prostate cancer
6. A restful sleep
