What are the reasons for the sour smell of leucorrhea during ovulation?

The sour smell of leucorrhea during ovulation may be related to vaginal flora imbalance, vaginitis, changes in hormone levels, poor personal hygiene habits, dietary factors and other reasons. During the ovulation period, estrogen levels in women's bodies increase, and vaginal secretions increase. If accompanied by abnormal sourness, you need to be alert to pathological factors.

1. Vaginal flora imbalance

The reduction of lactobacilli in the vagina may cause other microorganisms to overproduce and produce abnormal metabolites that cause sour taste. It manifests as increased secretion with a distinct odor, which may be accompanied by slight itching of the vulva. It can be adjusted by using vaginal probiotic preparations such as Dingjunsheng vaginal capsules to avoid excessive vaginal flushing on a daily basis.

2. Bacterial vaginosis

Infections by anaerobic bacteria such as Gardnerella will decompose amines to produce a fishy sour smell, and the secretions are often gray-white. Metronidazole effervescent vaginal tablets or clindamycin phosphate vaginal suppositories can be used as directed by your doctor. Sexual intercourse needs to be avoided during treatment.

3. Effects of hormone fluctuations

The estrogen peak during ovulation increases cervical mucus secretion by 2-3 times, and changes in the concentration of acidic components in the secretions may enhance odor perception. This physiological change usually does not require special treatment, just keep the vulva clean and dry.

4. Improper health management

Prolonged use of panty liners and non-breathable chemical fiber underwear will create a humid environment, prompting bacteria to decompose the protein in leucorrhea and produce odor. It is recommended to change pure cotton underwear every day. If there is a lot of secretion during ovulation, the vulva can be washed with warm water 1-2 times a day.

5. Abnormal diet structure

Excessive intake of spicy foods or high-sugar diets may change the vaginal pH. Metabolism of sulfur-containing foods such as onions and garlic will also aggravate the odor of secretions. Appropriately increasing foods rich in probiotics and vitamins such as yogurt and fresh vegetables can help improve the condition.

It is recommended to choose cotton underwear with good breathability and change it daily. Avoid using soap or lotion to clean the vulva excessively. If the sour smell lasts for more than 3 days or is accompanied by itching, burning sensation, or abnormal color of secretions, you should promptly see a gynecologist for routine leucorrhea examination. You can drink an appropriate amount of sugar-free yogurt every day to help maintain the balance of vaginal microecology, but you should be aware that people with lactose intolerance may experience discomfort such as bloating.
