Patient's question:
Now at night, I always want to have sex with my husband, but I'm afraid of getting pregnant.Doctor's answer:
1, Safe Period Method: Contraceptive success rate is 70%-80%.：Avoiding fertile period sexual activity based on ovulation patterns.
：For women with regular menstrual cycles, ovulation occurs approximately 14-16 days before the next expected period. The days around this date are considered unsafe, while other days are considered safe.
：During ovulation, symptoms such as mild abdominal pain, bloating, clear, stretchy cervical mucus, or slight bleeding may occur, along with increased libido. However, other factors can cause similar symptoms. Long-term use of this method is not very safe.
2, External Contraceptive Cream/Membrane: Contraceptive success rate is 70%-80%.
：Soluble membranes containing spermicidal drugs reduce sperm mobility.
：Before sexual intercourse, roll the membrane into a ball and place it into the vagina. It becomes effective after dissolving.
：Some people mistakenly ingest the membrane, while others place the separator paper between the membranes into the vagina. Neither action achieves contraception. Additionally, since membrane placement varies among individuals, the effectiveness is relatively poor.
3, Male Condom: Contraceptive success rate is 80%-98%.
：Prevent sperm from meeting with eggs.
：Before intercourse, the male places it over the reproductive organ.
：This is the most commonly used method among young people. Its biggest advantage is that it does not interfere with the female's physiology and also prevents sexually transmitted diseases. The main obstacle to consistent use is that, despite improvements in material quality, some people still feel the thin film hinders their best enjoyment of sex.
4, Liquid Condom: Contraceptive success rate is over 96%.
：This product works through chemical sterilization and physical barriers, killing multiple sexually transmitted disease pathogens and sperm within 1 minute to achieve contraception.
：Use the special applicator. 3 minutes before sleep or sexual activity, inject 4.2 ml of the gel into the vagina in one go. The effect lasts for 8 hours.
：This product has been tested by the National Family Planning Commission Science and Technology Research Institute, ensuring 100% sperm killing within 1 minute. Pregnant women who wish to conceive should not use it. Follow the instructions carefully!
5, Intrauterine Device (IUD): Contraceptive success rate is over 95%.
：Prevent fertilized eggs from implanting in the uterus.
：Inserted into the uterus by a doctor.
：Insertion and removal of the IUD require certain procedures. After insertion, symptoms such as increased menstrual flow, menstrual cramps, uterine perforation, or induced inflammation may occur. It is commonly used for postpartum women. Newly married women planning to avoid pregnancy for 1-2 years can use the "Mirena" IUD.
：Women with gynecological inflammation, irregular or excessive menstruation, or genital tumors should not use an IUD before being examined by a doctor.
