1. Long-acting contraceptive needles are generally divided into two categories. 1 is intramuscular injection, usually 2-3 times, lasting for three months to half a year, and one is vaginal injection (it is said that it hurts for half a month and sexual intercourse is forbidden). One injection can last up to three years. If you want to stop contraception, you must have sex directly after 3 months, and you must take short-acting or one-time contraception during this period. (mainly to avoid the influence of drug residues on sperm and reduce the occurrence of deformed children, premature babies and stillbirths)
2. Oral contraceptives, similar to female oral long-acting contraceptives, take 1 ~ 2 times a day, and you can't stop taking them, but you only need routine short-acting contraception of 1 month to stop contraception.
3. Ligation. This requires surgery. I didn't hear anyone reply after ligation. It should be permanent.
Two. Short-acting contraception
1. condoms, do I need to say more about this?
2. Emergency contraceptives, such as Yuting and Huiting, are theoretically effective within 72 hours after contraceptive failure, but the earlier they are taken, the greater the protective effect, but they should not exceed 1 time within 30 days. After all, the amount of "inconvenient" bleeding for women in those days is very large (women take it orally)
3. In vaginal contraception, it is common to put the medicated membrane and gel ointment (like LeLe fans) into the private parts of women and enjoy the pleasure of "no condom" after about 10 minutes. Generally, it is necessary to re-apply the medicine about 40 minutes after the drug is released to ensure the success of contraception (for external use by women).
Personally, the safest and most hygienic method for male contraception is condom+female emergency contraception. Although it affects "fun", on the one hand, it can avoid the spread of skin diseases, on the other hand, it does little harm to the body.
