What causes lack of lubrication during intercourse?

Generally, "no lubrication during intercourse" refers to vaginal dryness during sex. Vaginal dryness during intercourse may be caused by decreased libido, changes in the ovulation cycle, Sjögren's syndrome, bacterial vaginosis, premature ovarian insufficiency, and other factors. It is recommended to seek medical attention promptly, identify the underlying cause, and receive appropriate treatment under the guidance of a qualified physician. Specific analyses are as follows:

1. Decreased Libido

Psychological stress, fatigue, or emotional fluctuations may reduce sexual desire, leading to diminished sexual response and reduced secretion, resulting in vaginal dryness during intercourse. Usually no specific treatment is required; maintaining a positive mindset and open communication with one's partner is beneficial.

2. Changes in Ovulation Cycle

Vaginal discharge varies around the time of ovulation within the menstrual cycle. Reduced secretions outside the ovulation period may lead to vaginal dryness during intercourse. It is advisable to become familiar with one’s own physiological cycle and maintain good genital hygiene.

3. Sjögren's Syndrome

Sjögren's syndrome is an autoimmune disorder that affects exocrine glands such as salivary and lacrimal glands. In this condition, the immune system attacks the body's own glands, impairing or destroying their ability to secrete fluids, thus causing the aforementioned symptoms. It may also be accompanied by dry mouth, dry eyes, and dry skin. Patients are advised to take medications such as meloxicam tablets, penicillamine tablets, and levamisole hydrochloride tablets under a doctor's supervision.

4. Bacterial Vaginosis

Bacterial vaginosis may result from indirect transmission, sexual transmission, or excessive cleaning. Vaginitis can cause congestion and swelling of the vaginal mucosa, severely affecting vaginal lubrication and leading to vaginal dryness during intercourse. It is often accompanied by symptoms such as vaginal itching, burning pain, and increased vaginal discharge. Patients are advised to take medications such as metronidazole tablets, clindamycin hydrochloride capsules, and ornidazole tablets under medical guidance.

5. Premature Ovarian Insufficiency

Premature ovarian insufficiency is usually caused by genetic factors, diseases, or adverse environmental exposures. Ovarian failure leads to a sharp decline in estrogen levels, impairing the normal function of the vaginal mucosa and potentially causing vaginal dryness during intercourse. It is commonly associated with symptoms such as infrequent menstruation, amenorrhea, and infertility. Patients should follow medical advice to use medications such as progesterone capsules, estradiol valerate tablets, and nylestriol tablets.

In daily life, it is important to drink plenty of water, maintain healthy lifestyle habits, eat more fruits and vegetables, and avoid spicy and irritating foods.
