Puberty Blockers
Puberty blockers, also called puberty inhibitors or hormone blockers, are medicines used to postpone puberty in children. The most commonly used puberty blockers are gonadotropin-releasing hormone (GnRH) agonists, which suppress the production of sex hormones, including testosterone and estrogen. In addition to their use in treating precocious puberty (and sometimes idiopathic short stature) in children, puberty blockers are also used for transgender children to delay the development of unwanted sex characteristics, so as to allow transgender youth more time to explore their gender identity. The use of puberty blockers in transgender youth is supported by twelve major American medical associations, four Australian medical associations, the British Medical Association, and the World Professional Association for Transgender Health (WPATH). In Europe, some medical groups and countries have discouraged or limited the use of puberty blockers, including Sweden's National Board of ...

Puberty
Puberty is the process of physical changes through which a child's body matures into an adult body capable of sexual reproduction. It is initiated by hormonal signals from the brain to the gonads: the ovaries in a girl, the testes in a boy. In response to the signals, the gonads produce hormones that stimulate libido and the growth, function, and transformation of the brain, bones, muscle, blood, skin, hair, breasts, and sex organs. Physical growth—height and weight—accelerates in the first half of puberty and is completed when an adult body has been developed. Before puberty, the external sex organs, known as primary sexual characteristics, are sex characteristics that distinguish boys and girls. Puberty leads to sexual dimorphism through the development of the secondary sex characteristics, which further distinguish the sexes. On average, girls begin puberty at ages 10–11 and complete puberty at ages 15–17; boys generally begin puberty at ages 11–12 and c ...

National Board Of Health And Welfare (Sweden)
The Swedish National Board of Health and Welfare ( sv, Socialstyrelsen) is a Swedish government agency. The agency was the result of a merger between the National Swedish Board of Health and the Swedish Royal Board of Social Affairs in 1968. , it is headed by director-general Olivia Wigzell.

The Board establishes norms by issuing provisions and general advice. It evaluates legislation and activities conducted by municipalities, county councils and local authorities. It also issues certificates of registration to 17 professional groups. Another responsibility are the official national statistics in the social services, medical care, and health and disease.

Hormone
A hormone (from the Greek participle , "setting in motion") is a class of signaling molecules in multicellular organisms that are sent to distant organs by complex biological processes to regulate physiology and behavior. Hormones are required for the correct development of animals, plants and fungi. Due to the broad definition of a hormone (as a signaling molecule that exerts its effects far from its site of production), numerous kinds of molecules can be classified as hormones. Among the substances that can be considered hormones, are eicosanoids (e.g. prostaglandins and thromboxanes), steroids (e.g. oestrogen and brassinosteroid), amino acid derivatives (e.g. epinephrine and auxin), protein or peptides (e.g. insulin and CLE peptides), and gases (e.g. ethylene and nitric oxide). Hormones are used to communicate between organs and tissues. In vertebrates, hormones are responsible for regulating a variety of physiological processes and behavioral activities such as diges ...

Sexual Organ
A sex organ (or reproductive organ) is any part of an animal or plant that is involved in sexual reproduction. The reproductive organs together constitute the reproductive system. In animals, the testis in the male, and the ovary in the female, are called the ''primary sex organs''. All others are called ''secondary sex organs'', divided between the external sex organs—the genitals or external genitalia, visible at birth in both sexes—and the internal sex organs. Mosses, ferns, and some similar plants have gametangia for reproductive organs, which are part of the gametophyte. The flowers of flowering plants produce pollen and egg cells, but the sex organs themselves are inside the gametophytes within the pollen and the ovule. Coniferous plants likewise produce their sexually reproductive structures within the gametophytes contained within the cones and pollen. The cones and pollen are not themselves sexual organs. Terminology The ''primary sex organs'' are the gonads, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Annual Review Of Medicine
The ''Annual Review of Medicine'' is a peer-reviewed medical journal that publishes review articles about all aspects of medicine. It was established in 1950. Its longest-serving editors have been William P. Creger (1974–1993) and C. Thomas Caskey (2001–2019). The current editor is Mary E. Klotman. As of 2022, ''Journal Citation Reports'' gives the journal a 2021 impact factor of 16.048, ranking it seventh of 139 titles in the category "Medicine, Research & Experimental". History The first volume of the journal was published in 1950 by the nonprofit publishing company Annual Reviews. It noted that the more "active" areas of medicine would be covered in each volume, while other subdisciplines would be covered every two or three years. Its first editor was Windsor C. Cutting. In 1996, it was one of the first Annual Reviews journals to be published electronically.
