What causes blood streaks at the coronary hook, and what should be done?

Generally, the presence of blood streaks in the coronal sulcus may be caused by factors such as sexual activity or masturbation stimulation, improper local hygiene, sexually transmitted infections, balanoposthitis, or a short frenulum of the penis. Maintaining local cleanliness, washing with warm water, and using medications as directed by a physician are recommended. It is advised to seek timely medical consultation to identify the underlying cause and receive appropriate treatment according to medical advice. Specific causes are as follows:

1. Sexual activity or masturbation stimulation: During sexual activity or masturbation, friction and stimulation may cause capillary dilation or minor rupture in the coronal sulcus, resulting in blood streaks. This may be accompanied by mild pain or discomfort. Blood streaks caused by such physiological factors do not require specific treatment. It is recommended to maintain local cleanliness, avoid excessive stimulation, and allow for adequate rest.

2. Improper local hygiene: Inadequate cleaning of the coronal sulcus may lead to accumulation of dirt and bacteria, irritating the local skin and causing capillary dilation or inflammatory reactions, resulting in blood streaks. It may also be accompanied by itching in the coronal sulcus area. Maintaining cleanliness and dryness of the coronal sulcus, washing regularly with warm water, and avoiding the use of harsh cleansers are recommended.

3. Sexually transmitted infections: Sexually transmitted infections may damage the mucocutaneous tissues of the coronal sulcus, causing inflammatory reactions and capillary dilation, resulting in blood streaks. Sexually transmitted infections are typically contagious and can be spread through sexual contact. They may also present with blisters in the coronal sulcus area. Anti-infective treatment with medications such as benzathine penicillin for injection, cefixime capsules, or acyclovir tablets may be used under medical supervision.

4. Balanoposthitis: Balanoposthitis refers to inflammation of the inner layer of the foreskin and the glans penis, which can be caused by various pathogenic infections. Inflammatory stimulation may lead to mucosal congestion, edema, and capillary dilation in the coronal sulcus area, resulting in blood streaks. It may also be accompanied by pain in the coronal sulcus. Treatment under medical guidance with medications such as cefixime tablets, amoxicillin capsules, or clotrimazole cream may be used to achieve anti-inflammatory and antibacterial effects.

5. Short frenulum of the penis: A short frenulum of the penis refers to easy tearing or pulling during penile erection, leading to bleeding or blood streaks in the coronal sulcus. During erection or sexual intercourse, symptoms such as pain, tearing sensation, or bleeding may occur. Treatment options may include surgical procedures such as frenuloplasty, removal of prepubic fat, or excision of penile fibrous dartos fascia, as directed by a physician. Postoperative care should include maintaining local cleanliness and disinfection to prevent infection.

Maintaining good lifestyle habits and personal hygiene is important in daily life.
