Birth control methods can be temporary or permanent. Which is a permanent method of birth control?
Inga [223]

The permanent birth control method is vasectomy. A vasectomy is a procedure to make a man sterile, by blocking sperm from reaching the semen that is ejaculated from the penis. The fluid contains semen, but no sperm, so it prevents the pregnancy.

<h3>Further explanation </h3>

There are many birth control methods, some more effective than others. Some can prevent you from STD (Sexual Transmitted Disease) disease.  

1. Contraceptive pills/birth control pills

Birth control pill contains a combination of progesterone and estrogen hormone to control the ovaries and the uterus. Birth control pill works best when it is taken every single day at the same time of day. A Pill is an effective form of birth control, but even missing one day increases the chance of getting pregnant.

2. Male condoms.

This type of birth control not only prevent pregnancy but also prevent you from STD disease

3. The intrauterine device (IUD)

IUD is a coil and flexible T-shaped device that is placed in the uterus by a physician. There are two types of IUD, a copper, and a hormonal IUD.

4. Injections
