[a] [2] [3] Before adulthood, a male human is referred to as a boy (a male child or adolescent). Like most other male mammals, a man's genome usually inherits an X chromosome from the mother and a Y chromosome from the father. Sex differentiation of the male fetus is governed by the SRY gene on the Y chromosome.
Genetic sequencing is a second way for a scientist to determine biological sex in both humans and animals (distinct from sexing). It became widely available and popular at the turn of the century. [2] Genetic sequencing also allows for the determination of rare genetic events when the y chromosome is incomplete and a male animal has female ...
The symbol of the Roman god Mars (god of war) is often used to represent the male sex. It also stands for the planet Mars and is the alchemical symbol for iron.. Male (symbol: ♂) is the sex of an organism that produces the gamete (sex cell) known as sperm, which fuses with the larger female gamete, [1] [2] [3] or ovum, in the process of fertilisation.

[7] Standards of masculinity vary across different cultures and historical periods. In Western cultures, its meaning is traditionally drawn from being contrasted with femininity.
The human brain. Differences in male and female brain size are relative to body size. [83] Early research into the differences between male and female brains showed that male brains are, on average, larger than female brains. This research was frequently cited to support the assertion that women are less intelligent than men.
Robert Stoller, whose work was the first to treat sex and gender as "two different orders of data", in his book Sex and Gender: The Development of Masculinity and Femininity, [46] uses the term 'sex' to refer to the "male or the female sex and the component biological parts that determine whether one is a male or a female". [47]
Gender symbols intertwined. The red (left) is the female Venus symbol. The blue (right) represents the male Mars symbol.. Gender includes the social, psychological, cultural and behavioral aspects of being a man, woman, or other gender identity.
