Is it safe to masturbate 10 days after a diagnostic curettage?
Generally, masturbation is not recommended within 10 days after a diagnostic curettage. The detailed explanation is as follows:

Dilation and curettage (D&C) is an invasive procedure that may cause damage to the endometrium. Within the first 10 days after surgery, the endometrium is typically still in the healing phase. Masturbation during this period may trigger uterine contractions due to sexual stimulation, potentially leading to increased or recurrent vaginal bleeding, as well as discomfort such as abdominal pain. Additionally, if hygiene is not properly maintained during masturbation, bacteria may enter the reproductive system, increasing the risk of infections such as endometritis or salpingitis. During the first 10 postoperative days, patients have lower immunity and are more susceptible to infections, which could lead to conditions like vaginitis or pelvic inflammatory disease.
During recovery, it's important to maintain external genital hygiene by washing daily with warm water, avoid behaviors that might cause infection such as tub bathing or swimming, refrain from using any items that could introduce infection, and strictly follow all instructions and recommendations provided by the doctor.
