Birth control includes barrier methods, hormonal contraception, intrauterine devices (IUDs), sterilization, and behavioral methods.

Barrier

Male condoms in the rolled-up position

Barrier contraceptives are devices that attempt to prevent pregnancy by physically preventing sperm from entering the uterus. They include: male condoms, female condoms, cervical caps, diaphragms, and contraceptive sponges with spermicide.

Hormonal

Hormonal contraceptives inhibit ovulation and fertilization.These include oral pills, subdermalimplants, and injectable contraceptives as well as the patch, hormonal IUDs and the vaginal ring. The most commonly used hormonal contraceptive is the combined oral contraceptive pill—commonly known as "the pill"—which includes a combination of an estrogen and a progestin(progestogen)

Intrauterine devices

The contemporary intrauterine device (IUD) is a small 'T'-shaped birth control device, containing either copper or progesterone, which is inserted into the uterus. IUDs are a form of long-acting reversible contraception, the most effective type of reversible birth control.As of 2002, IUDs were the most widely used form of reversible contraception, with nearly 160 million users worldwide.Evidence supports both effectiveness and safety in adolescents

Sterilization

Surgical sterilization is available in the form of tubal ligation for women and vasectomy for men.There are no significant long term side effects and tubal ligation decreases the risk of ovarian cancer.Some women regret such a decision: about 5% over 30 years, and about 20% under 30.Short term complications are less likely from a vasectomy than a tubal ligation.Neither method offers protection from sexually transmitted infections

 

The human population is
increasing tremendously. Therefore, to regulate the population growth by regulating
reproduction has become a necessary demand in the present times. Various
contraceptive devices have been devised to reduce unwanted pregnancies, which
help in bringing down the increased birth rate and hence, in checking population
explosion.
