postscript:
According to the World Health Organization, about 3 million adolescent girls aged 15 to 19 each year worldwide choose unsafe abortion, and complications such as haemorrhage, infection, uterine perforation, genital tract and visceral damage during the termination of childbirth have become a major cause of death in adolescent girls worldwide.
With unintended pregnancies becoming younger and older, and most of the physical and mental pain borne by women alone, scientific contraception is essential. Whether or not to prepare for a new life should be decided by both men and women.

If they are unable to take birth control pills or latex condoms for allergies, women may consider skin burial and birth control rings, and married and postmarital children may consider birth control rings and sterilizations.
Female sterilization: valid for life, contraceptive success rate greater than 99%. Intra-abdominal surgery is required and is more expensive than male sterilization. There are surgical risks, such as bleeding, infection, pelvic inflammatory disease, etc., and require hospital observation after surgery.
Skin burial: A tiny silicone rod containing progestin is implanted into the upper arm, and the progesterone is slowly released into the bloodstream to suppress ovulation. The duration of use is generally 3 to 7 years, and the effective contraceptive rate is about 99%. There will be changes in menstrual patterns (which generally do not affect the body) and there may be hormone-related side effects.
According to the Science sub-journal, there is also a new contraceptive method recently listed: contraceptive microneedle patch, pressed for one minute, effective for a whole month.
