Yellow-green discharge


Recently, I visited a gynecologist due to vaginal itching, and the doctor prescribed an ointment for me.
After applying it, I noticed an increase in discharge, and the itching symptoms improved slightly.
Initially, the discharge was clear and white, which was fine, but today I found a large clump of dried yellow-green discharge on my underwear that had a slightly sour smell, reminiscent of foot odor.
Since I started using the ointment, I have been abstaining from sexual intercourse.
I would like to ask the doctor what condition this might indicate.
Additionally, after each sexual encounter, if my partner does not use a condom, I still experience itching at the vaginal opening even if there is no ejaculation.
Could this be an allergic reaction to his semen?

Dr. Huang Yiwen reply Obstetrics and Gynecology


Hello, Miss Wei: The presence of yellow-green vaginal discharge with an unpleasant odor is typically indicative of bacterial vaginosis, and it is essential to seek treatment from a gynecologist.
It is common to experience itching at the vaginal opening after sexual intercourse due to repeated friction and irritation from vaginal secretions, which usually resolves on its own after some time.
You may try applying a general anti-itch cream to alleviate the discomfort.

Understanding yellow-green vaginal discharge can be concerning, especially when accompanied by symptoms like itching and discomfort. Based on your description, it seems you may be experiencing a type of vaginitis, which is an inflammation of the vagina that can result from various causes, including infections, hormonal changes, or irritants.

The yellow-green discharge you mentioned, particularly if it has a strong odor and is accompanied by itching, could indicate a bacterial vaginosis or a yeast infection. Bacterial vaginosis is characterized by an imbalance of the normal bacteria in the vagina, leading to an overgrowth of certain bacteria. This condition often results in a thin, grayish-white discharge with a fishy odor. On the other hand, a yeast infection typically presents with thick, white, cottage cheese-like discharge, but it can also cause yellow-green discharge in some cases.

The fact that your discharge has changed to a yellow-green color and has a sour smell could suggest that there is an ongoing infection. The increase in discharge after using the medicated cream could be a result of the treatment stimulating the vaginal environment, which sometimes leads to an increase in discharge as the body responds to the treatment. However, if the discharge has changed in color and odor, it may be worth consulting with your healthcare provider again to ensure that the treatment is effective and appropriate for your condition.

Regarding your concern about experiencing itching after intercourse, it is possible that this could be a reaction to your partner's semen, especially if you have a sensitivity or allergy to certain proteins in the semen. This type of reaction is relatively rare but can occur. Alternatively, the itching could be a result of the existing infection or irritation in the vaginal area, which may be exacerbated by sexual activity.

Here are some steps you can take to address your symptoms:
1. Consult a Healthcare Provider: Since your symptoms have changed and you are experiencing new concerns, it is essential to follow up with a healthcare provider. They may recommend a pelvic exam, swabs for laboratory testing, or a different treatment plan based on your current symptoms.

2. Avoid Irritants: Until you can see a healthcare provider, avoid using scented soaps, douches, or other potential irritants in the vaginal area. These can exacerbate symptoms and disrupt the natural balance of bacteria.

3. Maintain Hygiene: Keep the genital area clean and dry. Wearing breathable cotton underwear can help reduce moisture buildup, which can worsen infections.

4. Consider Safe Sexual Practices: If you suspect a sensitivity to your partner's semen, consider using condoms during intercourse to see if this alleviates your symptoms. This can also help prevent the transmission of any potential infections.

5. Hydration and Diet: Ensure you are drinking enough water and maintaining a balanced diet, as this can impact your overall health and potentially your vaginal health as well.

6. Follow Treatment Instructions: If you are using any prescribed medications or creams, follow the instructions carefully. If you notice any worsening of symptoms, inform your healthcare provider.

In summary, the yellow-green discharge you are experiencing, particularly with the accompanying symptoms, suggests that you may have an infection that requires further evaluation. It is crucial to seek medical advice to determine the exact cause and appropriate treatment. Remember that open communication with your healthcare provider about your symptoms and concerns is vital for effective management.
