Introduction
In general, postcoital bleeding in women may result from mechanical friction during intercourse, ovulation-related bleeding, cervicitis, cervical polyps, endometritis, or other causes. If any discomfort occurs, it is advisable to seek prompt medical evaluation and treatment at a reputable hospital. In daily life, maintain external genital hygiene and avoid unprotected or unhygienic sexual activity. Refrain from intercourse during menstruation and while recovering from inflammatory conditions.

Generally, post-coital vaginal bleeding in women may result from mechanical friction during intercourse, ovulation-related bleeding, cervicitis, cervical polyps, or endometritis. If associated discomfort or symptoms occur, prompt consultation at a reputable hospital is recommended for proper diagnosis and treatment. A detailed analysis follows:

1. Mechanical Friction During Intercourse

Excessive friction during intercourse may cause minor trauma to the vaginal mucosa, leading to slight bleeding. To prevent this, reduce the frequency of intercourse, use gentler movements, maintain proper genital hygiene, and keep the external genitalia clean and dry.

2. Ovulation-Related Bleeding

Mild hormonal fluctuations during ovulation may cause minimal shedding of the endometrium; sexual stimulation can exacerbate this slight bleeding. Maintain good genital hygiene, limit intercourse frequency during ovulation, and adopt regular sleep patterns to stabilize endocrine function.

3. Cervicitis

Infection by pathogenic organisms triggers inflammation of the cervix, resulting in hyperemic and fragile cervical mucosa that is prone to injury and bleeding upon sexual stimulation. Treatment may include azithromycin dispersible tablets, cefuroxime axetil tablets, or tinidazole tablets, as prescribed by a physician. Sexual abstinence is mandatory during treatment, and daily external genital cleansing is advised.

4. Cervical Polyps

Benign proliferative growths arising from the cervical mucosa—cervical polyps—are soft in texture and easily rupture and bleed upon contact during intercourse. Medication typically yields limited efficacy; therefore, surgical excision of the polyp is usually required. Postoperatively, meticulous genital care is essential, and regular cervical examinations should be scheduled.

5. Endometritis

Inflammatory edema of the endometrium renders it fragile; sexual stimulation may induce minor endometrial shedding and bleeding. Treatment options—under medical supervision—include Fuke Qianjin tablets, clindamycin phosphate tablets, or levofloxacin capsules. Adequate rest is recommended, and pelvic congestion should be avoided.

In daily life, maintain cleanliness of the external genitalia and avoid unprotected or unhygienic intercourse. Refrain from intercourse during menstruation and while recovering from inflammatory conditions. Undergo annual cervical cancer screening (e.g., Pap smear or HPV testing), and seek timely medical evaluation and intervention for any abnormal vaginal bleeding.
