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.
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 ...
[2] [3] [4] It is distinct from the definition of the biological male sex, [5] [6] as anyone can exhibit masculine traits. [7] Standards of masculinity vary across different cultures and historical periods. In Western cultures, its meaning is traditionally drawn from being contrasted with femininity.

Male expendability, the relative expendability argument, or the expendable male hypothesis, is the idea that the lives of male humans are of less concern to a population than those of female humans because they are less necessary for population replacement.
Gender-based medicine, also called "gender medicine", is the field of medicine that studies the biological and physiological differences between the human sexes and how that affects differences in disease. Traditionally, medical research has mostly been conducted using the male body as the basis for clinical studies.
