Patient's question:
What are the disadvantages of external ejaculation? How can it be improved?Doctor's answer:
1. Safe Period Method: Contraceptive Success Rate: 70%-80%：Avoiding fertile period sexual activity based on ovulation patterns.
：For women with regular menstrual cycles, ovulation typically occurs about 14-16 days before the next expected period. The days immediately before and after this date are considered unsafe, while other days are considered safe.
：During ovulation, some women may experience mild abdominal pain, bloating, clear, stretchy cervical mucus, or slight bleeding, 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: 70%-80%
：A soluble membrane containing spermicide reduces sperm motility.
：Before sexual activity, the membrane is folded into a ball and inserted into the vagina, where it dissolves and becomes effective.
：Some people mistakenly ingest the membrane, while others insert the separator paper between the layers into the vagina. Neither action provides contraceptive protection. Additionally, since the placement of the membrane varies from person to person, its effectiveness is often poor.
3. Male Condom: Contraceptive Success Rate: 80%-90%
：Prevents sperm from meeting with eggs.
：Before intercourse, the condom is placed over the male reproductive organ.
：This is the most commonly used method among young people. Its biggest advantage is that it does not interfere with the woman's physiology and can also prevent sexually transmitted diseases (STIs). The main obstacle to consistent use is that, despite improvements in material quality, some people still feel that the thin film hinders their best enjoyment of sex.
