Combined injectable birth controlCombined injectable contraceptives (CICs) are a form of hormonal birth control for women. They consist of monthly injections of combined formulations containing an estrogen and a progestin to prevent pregnancy. CICs are different from progestogen-only injectable contraceptives (POICs), such as depot medroxyprogesterone acetate (DMPA; brand names Depo-Provera, Depo-SubQ Provera 104) and norethisterone enantate (NETE; brand name Noristerat), which are not combined with an estrogen and are given once every two to three months instead of once a month.
Pattern hair lossPattern hair loss (also known as androgenetic alopecia (AGA)) is a hair loss condition that primarily affects the top and front of the scalp. In male-pattern hair loss (MPHL), the hair loss typically presents itself as either a receding front hairline, loss of hair on the crown (vertex) of the scalp, or a combination of both. Female-pattern hair loss (FPHL) typically presents as a diffuse thinning of the hair across the entire scalp.
Β-Hydroxy β-methylbutyric acidβ-Hydroxy β-methylbutyric acid (HMB), otherwise known as its conjugate base, β-hydroxy β-methylbutyrate, is a naturally produced substance in humans that is used as a dietary supplement and as an ingredient in certain medical foods that are intended to promote wound healing and provide nutritional support for people with muscle wasting due to cancer or HIV/AIDS. In healthy adults, supplementation with HMB has been shown to increase exercise-induced gains in muscle size, muscle strength, and lean body mass, reduce skeletal muscle damage from exercise, improve aerobic exercise performance, and expedite recovery from exercise.
Pilosité humaineLa pilosité humaine est plus ou moins abondante chez tous les humains au sein même de différentes populations, mais la présence de poils au niveau des aisselles et des organes génitaux est constante. Dans l'espèce humaine il y a de manière invariable le même nombre ainsi que le même emplacement de follicules pileux et de poils qui en résultent. Les seules différences que l'on peut constater chez l'homme proviennent de l'influence des hormones androgènes (testostérone essentiellement) sur les follicules pileux donnant lieu à des variations de type de poil.
Nandrolone phenylpropionateNandrolone phenylpropionate (NPP), or nandrolone phenpropionate, sold under the brand name Durabolin among others, is an androgen and anabolic steroid (AAS) medication which has been used primarily in the treatment of breast cancer and osteoporosis in women. It is given by injection into muscle once every week. Although it was widely used in the past, the drug has mostly been discontinued and hence is now mostly no longer available. Side effects of NPP include symptoms of masculinization like acne, increased hair growth, voice changes, and increased sexual desire.
EthisteroneEthisterone, also known as ethinyltestosterone, pregneninolone, and anhydrohydroxyprogesterone and formerly sold under the brand names Proluton C and Pranone among others, is a progestin medication which was used in the treatment of gynecological disorders but is now no longer available. It was used alone and was not formulated in combination with an estrogen. The medication is taken by mouth. Side effects of ethisterone include masculinization among others.
ÉthinylestradiolL'éthinylestradiol, ou éthinyl estradiol (EE), est un dérivé de synthèse de l'estradiol. C'est l'œstrogène actif par voie orale le plus utilisé au monde. On le trouve dans presque toutes les formulations modernes des pilules contraceptives combinées. L'EE est excrété dans les urines et les fèces. C'est un estrogène de synthèse qui est donc libéré dans la nature sans que l'on en connaisse les conséquences.
NorgestrienoneNorgestrienone, sold under the brand names Ogyline, Planor, and Miniplanor, is a progestin medication which has been used in birth control pills, sometimes in combination with ethinylestradiol. It was developed by Roussel Uclaf and has been registered for use only in France. Under the brand name Planor, it has been marketed in France as 2 mg norgestrienone and 50 μg ethinylestradiol tablets. It is taken by mouth. Norgestrienone is a progestin, or a synthetic progestogen, and hence is an agonist of the progesterone receptor, the biological target of progestogens like progesterone.
HormonothérapieEn médecine, l'hormonothérapie est un traitement médicamenteux à base de différentes hormones parmi lesquelles les hormones de croissance et les hormones sexuelles, les hormones thyroïdiennes et bien d'autres molécules endogènes. Ce traitement visant en principe à remplacer la sécrétion d'une hormone, les termes hormonosubstitution ou traitement hormonal substitutif (THS) sont parfois utilisés pour le désigner.
GynécomastieLa gynécomastie est le développement excessif des glandes mammaires chez l'homme. Elle peut toucher un sein (gynécomastie unilatérale) ou les deux (gynécomastie bilatérale). La gynécomastie est courante de manière éphémère au cours de la puberté. Sa forme persistante peut être en revanche congénitale ou due à une maladie, une tumeur ou à la prise de certains médicaments. vignette|Gynécomastie bénigne chez un garçon en pleine puberté. Les enfants peuvent être concernés dès la naissance, et parfois avec un seul sein hypertrophié.
