Postcoital bleeding


Hello, doctor.
In the second half of 2022, I had blood tests showing FSH at 4.92 mIU/ml and LH at 17.60 mIU/ml.
The doctor diagnosed me with mild polycystic ovary syndrome (PCOS).
I underwent six months of ovulation induction treatment without improvement and have recently switched to traditional Chinese medicine treatment.
Before the diagnosis, I experienced light bleeding during sexual intercourse, lasting about two days.
Recently, the bleeding has increased significantly, resembling drops of water, similar to menstrual bleeding, lasting about 3-4 days (with heavier bleeding on the first day).
I would like to know what could be causing this bleeding and what treatment options are available.
Between 2021 and 2022, I had a Pap smear that returned normal results, and I also underwent a pelvic examination, which was normal as well.
The timing of sexual intercourse has not been around my menstrual period.

Common causes of post-coital bleeding include: 1.
Vaginal tissue injury 2.
Vaginal dryness: such as in menopausal genitourinary syndrome, excessive vaginal douching, childbirth, and breastfeeding.
3.
Uterine polyps and fibroids 4.
Infections: including yeast infections, pelvic inflammatory disease, cervicitis, vaginitis, and sexually transmitted infections (such as chlamydia and gonorrhea).
5.
Other causes: cervical ectopia, endometriosis, cervical dysplasia, and cervical cancer.
It is recommended to consult a gynecologist for examination; the physician may diagnose conditions such as endometrial polyps or cervical infections to identify the underlying cause and provide treatment.
Thank you! Wishing you peace and health, Dr.
Zhang.

Post-coital bleeding (PCB) is a condition that can be concerning for many individuals, and understanding its causes and treatment options is essential for effective management. In your case, the history of polycystic ovary syndrome (PCOS) and the recent increase in bleeding after sexual intercourse warrant a thorough evaluation.

Causes of Post-Coital Bleeding:
1. Cervical Issues: Although you mentioned that your Pap smear results were normal, it is still possible to have cervical ectropion (also known as cervical erosion), which is a condition where the cells from the inside of the cervical canal are present on the outside of the cervix. This can lead to bleeding after intercourse, especially if there is friction or irritation.

2. Vaginal Dryness or Atrophy: Hormonal changes, particularly those associated with PCOS or other endocrine disorders, can lead to vaginal dryness. This can cause discomfort and bleeding during or after intercourse.

3. Infections: Sexually transmitted infections (STIs) or other vaginal infections can cause inflammation and bleeding. Even if you have had normal examinations, some infections may not be immediately apparent.

4. Uterine Issues: Conditions such as fibroids or polyps can also lead to post-coital bleeding. These growths can cause irregular bleeding patterns and may require further investigation.

5. Hormonal Imbalances: Given your history of PCOS, hormonal fluctuations can affect the menstrual cycle and lead to unexpected bleeding.
6. Trauma or Injury: Sometimes, the act of intercourse can cause minor trauma to the vaginal or cervical tissues, especially if there is insufficient lubrication.

Treatment Options:
1. Further Evaluation: It is crucial to follow up with your healthcare provider for a comprehensive evaluation. This may include a pelvic ultrasound to assess for any structural abnormalities, such as fibroids or polyps, and possibly a hysteroscopy if indicated.

2. Hormonal Treatment: If hormonal imbalances are contributing to the bleeding, your doctor may consider adjusting your current treatment plan. This could involve hormonal contraceptives to help regulate your menstrual cycle and reduce bleeding.

3. Lubrication: If vaginal dryness is a concern, using a water-based lubricant during intercourse can help reduce friction and irritation, potentially alleviating bleeding.

4. Infection Treatment: If an infection is suspected, appropriate testing and treatment with antibiotics or antifungals may be necessary.

5. Regular Monitoring: Keeping track of your menstrual cycle and any bleeding patterns can provide valuable information for your healthcare provider.
6. Alternative Therapies: Since you are currently exploring traditional Chinese medicine, it may be beneficial to discuss this with your healthcare provider to ensure that any herbal treatments do not interfere with your current medications or conditions.

In conclusion, while post-coital bleeding can be alarming, it is essential to approach it systematically. Given your history of PCOS and the recent changes in your bleeding pattern, a thorough evaluation by a healthcare professional is crucial to determine the underlying cause and appropriate treatment. Do not hesitate to seek a second opinion if you feel that your concerns are not being adequately addressed. Your health and well-being are paramount, and understanding the root cause of your symptoms is the first step toward effective management.
