contraception
(noun)
The use of a device or procedure to prevent conception as a result of sexual activity.
Examples of contraception in the following topics:
-
Hormonal Methods
- Hormonal contraception is a type of birth control method that acts on the endocrine system.
- The original hormonal method—the combined oral contraceptive pill—was first marketed as a contraceptive in 1960.
- Altogether, 18% of the world's contraceptive users rely on hormonal methods.
- Combined hormonal contraceptives prevent ovulation by suppressing the release of gonadotropins.
- Oral contraceptives typically come in foil packets with designated pills for each day.
-
Spermicides
- Spermicide is a contraceptive substance that eradicates sperm and is inserted vaginally prior to intercourse to prevent pregnancy.
- Spermicide is a contraceptive substance that eradicates sperm and is inserted vaginally prior to intercourse to prevent pregnancy.
- As a contraceptive, spermicide may be used alone.
- Usually spermicides are combined with contraceptive barrier methods such as diaphragms, condoms, cervical caps, and sponges.
- Spermicides are believed to increase the contraceptive efficacy of condoms.
-
Intrauterine Devices (IUDs)
- Names and descriptors of intrauterine contraceptive devices vary by location.
- In the United States, two types of intrauterine contraceptive (both referred to as IUDs) are available: the copper Paragard and the hormonal Mirena.
- Hormonal intrauterine contraceptives are considered to be a different type of birth control, and they are distinguished with the term intrauterine system or IUS.
- Although use of the Mirena results in much lower systemic progestogen levels than other very-low-dose progestogen-only hormonal contraceptives, it may still have some of the same side effects as low does progesterone-only hormonal contraceptives.
- Unlike oral contraceptives, with the use of the Mirena the hormones are localized to the uterine area.
-
Barrier Methods
- Barrier contraception methods prevent pregnancy by physically preventing sperm from entering the uterus.
- Barrier contraception methods prevent pregnancy by physically preventing sperm from entering the uterus.
- The cervical cap is a form of female barrier contraception.
- The diaphragm has become an increasingly unpopular method of birth control, replaced with oral contraceptives and IUDs.
- In 2002, only 0.2% of American women were using a diaphragm as their primary method of contraception.
-
Periodic Abstinence
- Of commonly known methods of birth control, only the cervical cap and contraceptive sponge have comparably high failure rates.
- However, the length of the pre-ovulatory phase can vary significantly, depending on the woman's typical cycle length, stress factors, medication, illness, menopause, breastfeeding, and whether she is just coming off hormonal contraception.
- This schematic of a typical female menstrual cycle shows that periods of ovulation are taken in account to be a period of abstinence in calendar-based contraception methods.
-
Ovarian Cancer
- Use of combined oral contraceptive pills is a protective factor.
- Early age at first pregnancy, older age of final pregnancy and the use of low dose hormonal contraception have also been shown to have a protective effect.
-
Testes Ducts
- The procedure of deferentectomy, also known as a vasectomy, is a method of contraception in which the vasa deferentia are permanently cut, though in some cases it can be reversed.
- Research in male contraception have focused primarily on the vas deferens with the use of the intra-vas device and reversible inhibition of sperm under guidance.
-
Raynaud's Phenomenon
- Raynaud's may be aggravated by hormones and hormone regulators, such as hormonal contraception.
- Contraception that is low in estrogen is preferable, and the progesterone-only pill is often prescribed for women with Raynaud's.
-
Vulvovaginal Candidiasis
- The evidence of the effect of oral contraceptives is controversial.
-
Carpal Tunnel Syndrome
- Some common conditions that can lead to CTS include obesity, oral contraceptives, hypothyroidism, arthritis, diabetes, and trauma.
