Eugen Steinach
Eugen Steinach (28 January 1861 – 14 May 1944) was an Austrian physiologist and pioneer in endocrinology. Steinach played a significant role in discovering the relationship between sex hormones (estrogen and testosterone) and human physical identifiers. Life and career Steinach was born on 28 January 1861, in Hohenems, County of Tyrol, Austrian Empire. His family were well-off and had been prominent in Jewish affairs in Hohenems for several generations. His father and his grandfather were both physicians; his father studied under Ernst Wilhelm von Brücke, a leading German physiologist. Steinach was a physiologist, hormone researcher and biology professor who became the Director of Vienna's Biological Institute of the Academy of Sciences in 1912, the year in which he conducted experiments in the transplantation of a male guinea pig's testes into a female and the castration of the male. The testes secretion, now known as testosterone, resulted in the female guinea pig develop ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Castration
Castration is any action, surgical, chemical, or otherwise, by which an individual loses use of the testicles: the male gonad. Surgical castration is bilateral orchiectomy (excision of both testicles), while chemical castration uses pharmaceutical drugs to deactivate the testes. Castration causes sterilization (preventing the castrated person or animal from reproducing); it also greatly reduces the production of hormones, such as testosterone and estrogen. Surgical castration in animals is often called neutering. The term ''castration'' is sometimes also used to refer to the removal of the ovaries in the female, otherwise known as an oophorectomy, or the removal of internal testes, otherwise known as gonadectomy. The equivalent of castration for female animals is spaying. Estrogen levels drop following oophorectomy, and long-term effects of the reduction of sex hormones are significant throughout the body. Castration of animals is intended to favor a desired development of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Nobel Prize
The Nobel Prizes ( ; sv, Nobelpriset ; no, Nobelprisen ) are five separate prizes that, according to Alfred Nobel's will of 1895, are awarded to "those who, during the preceding year, have conferred the greatest benefit to humankind." Alfred Nobel was a Swedish chemist, engineer, and industrialist most famously known for the invention of dynamite. He died in 1896. In his will, he bequeathed all of his "remaining realisable assets" to be used to establish five prizes which became known as "Nobel Prizes." Nobel Prizes were first awarded in 1901. Nobel Prizes are awarded in the fields of Physics, Chemistry, Physiology or Medicine, Literature, and Peace (Nobel characterized the Peace Prize as "to the person who has done the most or best to advance fellowship among nations, the abolition or reduction of standing armies, and the establishment and promotion of peace congresses"). In 1968, Sveriges Riksbank (Sweden's central bank) funded the establishment of the Prize in Economi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
William Butler Yeats
William Butler Yeats (13 June 186528 January 1939) was an Irish poet, dramatist, writer and one of the foremost figures of 20th-century literature. He was a driving force behind the Irish Literary Revival and became a pillar of the Irish literary establishment who helped to found the Abbey Theatre. In his later years he served two terms as a Senator of the Irish Free State. A Protestant of Anglo-Irish descent, Yeats was born in Sandymount and was educated in Dublin and London and spent childhood holidays in County Sligo. He studied poetry from an early age, when he became fascinated by Irish legends and the occult. These topics feature in the first phase of his work, lasting roughly from his student days at the Metropolitan School of Art in Dublin until the turn of the 20th century. His earliest volume of verse was published in 1889, and its slow-paced and lyrical poems display debts to Edmund Spenser, Percy Bysshe Shelley and the poets of the Pre-Raphaelite Brotherhood. F ...

Morris Fishbein Doctor of Medicine, M.D. (July 22, 1889 – September 27, 1976) was an American physician and editor of the ''Journal of the American Medical Association'' (''JAMA'') from 1924 to 1950. Ira Rutkow's ''Seeking the Cure: A History of Medicine in America'' provides a brief overview of Fishbein's influence on American medicine during the Interwar period. Fishbein is vilified in the chiropractic community due to his principal role in founding and propagating the campaign to suppress and end chiropractic as a profession due to its basis in pseudoscientific practices.

Testicle
A testicle or testis (plural testes) is the male reproductive gland or gonad in all bilaterians, including humans. It is homologous to the female ovary. The functions of the testes are to produce both sperm and androgens, primarily testosterone. Testosterone release is controlled by the anterior pituitary luteinizing hormone, whereas sperm production is controlled both by the anterior pituitary follicle-stimulating hormone and gonadal testosterone. Structure Appearance Males have two testicles of similar size contained within the scrotum, which is an extension of the abdominal wall. Scrotal asymmetry, in which one testicle extends farther down into the scrotum than the other, is common. This is because of the differences in the vasculature's anatomy. For 85% of men, the right testis hangs lower than the left one. Measurement and volume The volume of the testicle can be estimated by palpating it and comparing it to ellipsoids of known sizes. Another method is to use caliper ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sperm
Sperm is the male reproductive cell, or gamete, in anisogamous forms of sexual reproduction (forms in which there is a larger, female reproductive cell and a smaller, male one). Animals produce motile sperm with a tail known as a flagellum, which are known as spermatozoa, while some red algae and fungi produce non-motile sperm cells, known as spermatia. Flowering plants contain non-motile sperm inside pollen, while some more basal plants like ferns and some gymnosperms have motile sperm. Sperm cells form during the process known as spermatogenesis, which in amniotes ( reptiles and mammals) takes place in the seminiferous tubules of the testes. This process involves the production of several successive sperm cell precursors, starting with spermatogonia, which differentiate into spermatocytes. The spermatocytes then undergo meiosis, reducing their chromosome number by half, which produces spermatids. The spermatids then mature and, in animals, construct a tail, or flagellum, ...
