Oral Form Levonorgestrel Hormone White Powder Oral Tablets Male Health
Levonorgestrel, also known as 17α-ethynyl-18-methyl-19-nortestosterone or as 17α-ethynyl-18-methylestr-4-en-17β-ol-3-one, is a synthetic estrane steroid and a derivative of testosterone. It is the C13β or levorotatory stereoisomer and enantiopure form of norgestrel, the C13α or dextrorotatory isomer being inactive. Levonorgestrel is more specifically a derivative of norethisterone (17α-ethynyl-19-nortestosterone) and is the parent compound of the gonane (18-methylestrane) subgroup of the 19-nortestosterone family of progestins.
Levonorgestrel, synthetic progestogen (any progestational steroid, such as progesterone) that is used as a form of contraception in women.
In addition, levonorgestrel causes the mucus in the cervix to thicken, which blocks the ability of sperm to travel through the uterus and into the fallopian tubes, where fertilization of the egg by a sperm normally takes place.
As a form of progesterone, levonorgestrel exerts its actions on the hypothalamus through a negative feedback mechanism, which causes a decrease in the secretion of luteinizing hormone (LH) and follicle-stimulating hormone (FSH).
Levonorgestrel is the mirror compound (enantiomer) of norgestrel, which was synthesized in the early 1960s by American scientist Herschel Smith at the U.S.-based company Wyeth Pharmaceuticals. Both LH and FSH normally stimulate ovulation. Thus, by reducing their secretion, levonorgestrel serves to inhibit ovulation. The drug also inhibits implantation, the point when a fertilized egg embeds in the uterine wall, where it will grow and develop into an embryo.
