<p><b>New page</b></p><div>[[File:Levonorgestrel acetate.svg|thumb|{{PAGENAME}}]] <br>'''Levonorgestrel acetate''' is a [[synthetic]] [[progestogen]] used in various [[hormonal contraception|contraceptive]] methods. It is a derivative of [[19-nortestosterone]] and is also known as '''17α-acetoxy-18-methyl-19-nor-δ4-testosterone'''.<br />
<br />
==Chemistry==<br />
Levonorgestrel acetate is a synthetic progestogen, specifically a [[17α-alkylated]] 19-nortestosterone derivative. It is structurally related to other 19-nortestosterone progestogens such as [[norgestrel]] and [[norgestimate]].<br />
<br />
==Pharmacology==<br />
Levonorgestrel acetate acts primarily by preventing [[ovulation]] through the suppression of the [[gonadotropin]]s [[luteinizing hormone]] (LH) and [[follicle-stimulating hormone]] (FSH). It also increases the thickness of the [[cervical mucus]], which inhibits [[sperm]] penetration and reduces the likelihood of [[fertilization]].<br />
<br />
==Clinical use==<br />
Levonorgestrel acetate is used in a variety of contraceptive methods, including [[intrauterine devices]] (IUDs), [[contraceptive implant|contraceptive implants]], and [[oral contraceptive pill|oral contraceptive pills]]. It is also used in [[emergency contraception]].<br />
<br />
==Side effects==<br />
Common side effects of levonorgestrel acetate include [[nausea]], [[breast tenderness]], [[headache]], and changes in [[menstrual bleeding]] patterns. Less common side effects include [[mood changes]], [[weight gain]], and [[acne]].<br />
