Can drug irrigation prevent pregnancy?
Medicated douching of the vagina generally cannot prevent pregnancy. It is recommended to choose an appropriate contraceptive method under medical guidance. The detailed explanation is as follows:
Pregnancy occurs when sperm fertilizes an egg, forming a zygote that implants in the uterus and develops. A typical male ejaculation releases approximately 1.5 ml of semen containing a large number of sperm, which are directly deposited into the uterus. Medications used for vaginal douching usually cannot completely remove all semen from the vagina and uterus. If sperm have high motility and the woman is in her ovulation period, there remains a significant chance of pregnancy.
It is recommended to use contraception according to medical advice, such as taking oral contraceptives or using condoms. Additionally, consult a doctor before using any medication for vaginal douching to avoid inappropriate or blind use of drugs.
