Definition, etymology, and use
According to the ''Merriam-Webster Dictionary'', a boy is "a male child from birth to adulthood".
The word "boy" comes from
Middle English ''boi, boye'' ("boy, servant"), related to other
Germanic words for ''boy'', namely
East Frisian ''boi'' ("boy, young man") and
West Frisian ''boai'' ("boy"). Although the exact
etymology is obscure, the English and Frisian forms probably derive from an earlier
Anglo-Frisian *''bō-ja'' ("little brother"), a diminutive of the Germanic root *''bō-'' ("brother, male relation"), from
Proto-Indo-European *''bhā-'', *''bhāt-'' ("father, brother"). The root is also found in
Norwegian dialectal ''boa'' ("brother"), and, through a reduplicated variant *''bō-bō-'', in
Old Norse ''bófi'',
Dutch ''boef'' "(criminal) knave, rogue",
German ''Bube'' ("knave, rogue, boy"). Furthermore, the word may be related to ''Bōia'', an
Anglo-Saxon
The Anglo-Saxons were a Cultural identity, cultural group who inhabited England in the Early Middle Ages. They traced their origins to settlers who came to Britain from mainland Europe in the 5th century. However, the ethnogenesis of the Anglo- ...

Sex determination
Human sex is determined at
fertilization when the

sex of the
zygote has been initialized by a
sperm

girl will develop. A sperm cell carrying a Y chromosome results in an XY combination, and a boy will develop.
In utero development and genitalia
In male embryos at six to seven weeks' gestation, "the expression of a gene on the Y chromosome induces changes that result in the development of the testes". At approximately nine weeks' gestation, the production of testosterone by a male embryo results in the development of the male reproductive system.
The
male reproductive system includes both external and internal organs. The external organs include the
penis, the
scrotum, and the
testicles (or testes). The penis is a cylindrical organ filled with spongy tissue. It is the organ used by boys to expel
urine. The foreskin of some boys' penises is removed in a process known as
circumcision. The scrotum is a loose sac of skin behind the penis which contains the testicles. Testicles are oval-shaped gonads. A boy generally possesses two testicles. Internal male reproductive organs include the
vas deferens, the
ejaculatory ducts

Physical maturation
Puberty is the process by which children's bodies mature into adult bodies that are capable of reproduction. On average, boys begin puberty at ages 11–12 and complete puberty at ages 16–17.
In boys, puberty begins with the enlargement of the testicles and scrotum. The penis also increases in size, and a boy develops pubic hair. A boy's testicles also begin making sperm. The release of semen, which contains sperm and other fluids, is called ejaculation.
During puberty, a boy's erect penis becomes capable of

female.
A boy's first ejaculation is an important milestone in his development. On average, a boy's first
ejaculation occurs at age 13.
[(Jorgensen & Keiding 1991).] Ejaculation sometimes occurs during sleep; this phenomenon is known as a
nocturnal emission.
When a boy reaches puberty,
testosterone triggers the development of secondary sex characteristics. A boy's muscles increase in size and mass, his voice deepens, his bones lengthen, and the shape of his face and body changes.
The increased secretion of testosterone from the testicles during puberty causes the male secondary sexual characteristics to be manifested. Male secondary sex characteristics include:

Gender norms
Boys who defy gender norms may face a higher risk of abuse, and may experience more depression than gender-conforming peers, as well as
social stigma from parents and peers.
In some cultures, the birth of a male child (boy) is considered prosperous.
Boys and child labor
Boys perform the majority of
child labor around the world compared to girls, 88 million are boys and 64 million are girls. Boys are also the primary victims of
hazardous child labor. They are mainly employed in
agriculture,
construction and
mining sectors. Boy workers also account for about 87 percent of those who died on the job between 2003 and 2016 in the US.
Boys are given a basic reading, writing and mathematics skill and then forced to pursue their father's profession in order to alleviate financial burden of the family. This is one of the main reasons why boys are preferred over girl by the rural communities in poor countries. In
India, by contrast, the majority of adopted children are girls even though boys are preferred in general compared to girls.
