	~~'''~~Progestogen-only pill''' ('''POP''') is a type of [[contraceptive]] that contains a synthetic version of the hormone [[progestogen]]. It is also known as the '''mini-pill''' and is different from the [[combined oral contraceptive pill]] which contains both progestogen and [[estrogen]].		== Progestogen-only Pill ==

	== Mechanism of ~~action~~ ==		The '''progestogen-only pill''' (POP), also known as the '''mini-pill''', is a type of [[oral contraceptive]] that contains only [[progestogen]] hormones, unlike the [[combined oral contraceptive pill]] which contains both [[estrogen]] and progestogen. The primary function of the progestogen-only pill is to prevent [[pregnancy]] by altering the cervical mucus and the endometrial lining, and in some cases, suppressing [[ovulation]].
	The progestogen-only pill works primarily by thickening the [[cervical mucus]] to ~~prevent~~ [[sperm]] ~~from reaching an~~ [[~~egg~~]]~~. It also thins~~ the lining of the [[uterus]] ~~to make~~ it less ~~likely~~ for a fertilized egg ~~to implant and grow~~. ~~Some types of~~ progestogen-only pill ~~can~~ also ~~stop~~ [[ovulation]].

			== Mechanism of Action ==

			The progestogen-only pill works primarily by thickening the [[cervical mucus]], which acts as a barrier to [[sperm]] penetration. This change in the cervical mucus is the main mechanism by which the POP prevents pregnancy. Additionally, the progestogen-only pill alters the [[endometrium]] (the lining of the [[uterus]]), making it less suitable for [[implantation]] of a fertilized [[egg]]. In some women, the progestogen-only pill also suppresses [[ovulation]], although this is not its primary mechanism of action.

			== Types of Progestogen ==

			There are several types of progestogens used in progestogen-only pills, including [[norethisterone]], [[levonorgestrel]], and [[desogestrel]]. Each of these progestogens has slightly different properties and may be chosen based on individual health needs and side effect profiles.

			== Usage and Administration ==

			The progestogen-only pill is taken orally, once a day, at the same time each day. Consistency in timing is crucial for maintaining its effectiveness. Unlike the combined pill, there is no "pill-free" week, and the POP must be taken continuously.

	== Effectiveness ==		== Effectiveness ==
	The effectiveness of the progestogen-only pill depends on how consistently and correctly it is used. With perfect use, it is over 99% effective at preventing [[pregnancy]]. However, with typical use, the effectiveness is around 92%.

	== Side ~~effects~~ ==		When taken correctly, the progestogen-only pill is over 99% effective at preventing pregnancy. However, typical use, which may include missed pills or taking the pill at varying times, reduces its effectiveness to about 91%.
	Common side effects of the progestogen-only pill include [[menstrual ~~irregularities]]~~, ~~[[mood changes]]~~, [[breast tenderness]], and ~~[[acne]]~~. ~~Less common side effects include [[ovarian cysts]]~~, ~~[[decreased libido]], and [[weight gain]]~~.
			== Side Effects ==

			Common side effects of the progestogen-only pill include irregular menstrual bleeding, headaches, breast tenderness, and mood changes. Some women may experience no periods at all, while others may have more frequent or prolonged bleeding.

	== ~~Contraindications~~ ==		== Advantages and Disadvantages ==
	~~The progestogen-only pill is not suitable for everyone. It should not be used by women who have [[breast cancer]], [[liver disease]], or a history of [[stroke]] or [[blood clots]].~~

	== Advantages ~~and disadvantages~~ ==		=== Advantages ===
	The progestogen-only pill has several advantages over other forms of contraception. It can be used by women who cannot take estrogen, such as those who are [[breastfeeding]] or have a history of [[migraine]] with aura. It also does not interfere with sex and can be stopped at any time.

	~~However, the progestogen-only pill also has some disadvantages~~. ~~It must~~ be ~~taken at the same time every day~~ to ~~be effective, and it does~~ not protect against [[sexually transmitted infections]].		* Suitable for women who cannot take estrogen.
			* Can be used during [[breastfeeding]].
			* Lower risk of [[thrombosis]] compared to combined pills.

			=== Disadvantages ===

			* Requires strict adherence to daily timing.
			* May cause irregular bleeding patterns.
			* Does not protect against [[sexually transmitted infections]] (STIs).
