The American business magazine Forbes published a new study on sex. Point out that harmonious sex not only makes people happy physically and mentally, but also brings many unexpected benefits. The British "Daily Mail" also wrote an article pointing out that sex can help people detect certain diseases, thereby extending life.

In this regard, Yang Dazhong, an attending physician at the Department of Sexual Medicine at Yuquan Hospital of Tsinghua University, said: "Some symptoms associated with sexual life can indeed help people detect potential diseases early." For men, the following conditions should be paid attention to: .

Sudden ED (erectile dysfunction) suggests heart disease. ED is a local manifestation of a variety of systemic diseases and can occur 2 to 3 years before coronary heart disease. Because the cavernous arteries of the penis are very small, most blood vessel blockages will start from small blood vessels.

Check the urinary system for painful ejaculation. Pain during ejaculation may be caused by inflammation of the urinary system such as prostatitis or urethritis. Inflammation causes local tissue to become congested and swollen, causing pain.

Deterioration in sexual desire and alert to a decrease in hormones. If middle-aged people have symptoms such as low sexual desire and poor sexual function, accompanied by irritability and easy sweating, it may be due to a decrease in male hormones. It is best to go to the andrology department of the hospital for an endocrine examination.

Abnormal semen is associated with a variety of diseases. If the semen appears red, the most likely cause is seminal vesiculitis or prostatitis. Blood vessel rupture caused by high blood pressure, diabetes, etc. cannot be ruled out.

For women, some feelings before and after sex can also help detect gynecological diseases.

Be wary of cervicitis if you bleed during sex. Bleeding during intercourse is often a sign of cervical lesions such as cervicitis and cervical cancer. At this time, you must stop having sex and go to the hospital for examination as soon as possible.

Stomach pain after sex indicates pelvic inflammatory disease. Stomach pain and low back pain after sex may be related to pelvic inflammatory disease, endometriosis, etc. The pain generally lasts for a long time.

Be alert to vaginitis if there is a peculiar smell during sex. If vaginal secretions have a fishy smell and are unclear in color during sex, you may have vaginitis and should be checked in time.
