Clinically, if there is vaginal dryness and no secretion, it is mostly due to the decrease of secretion caused by premature ovarian failure or the decline of ovarian function and estrogen level after entering menopause. It is recommended that if the ovarian function is premature failure, you can take oral supplementation and progesterone artificial cycle treatment, and the vaginal secretion will also increase. If there is a decrease in estrogen levels due to menopause, and the vagina is dry and has no discharge, it is recommended that Ovitin ointment be applied intravaginally for treatment. It is also clinically recommended to rule out vaginal dryness, which is treated differently than normal vaginal dryness.
