Female mate guarding in humans Human mate guarding refers to behaviours employed by both males and females with the aim of maintaining reproductive opportunities and sexual access to a mate. It involves discouraging the current mate from abandoning the relationship whilst also warding off intrasexual (same sex) rivals.
Sex differences in human physiology are distinctions of physiological characteristics associated with either male or female humans. These can be of several types, including direct and indirect, direct being the direct result of differences prescribed by the Y-chromosome (due to the SRY gene ), and indirect being characteristics influenced ...
Human female mating competition is complex and multifaceted and varies across cultures, societies, and individuals. [94] Females may compete for high-quality mates who possess traits that indicate underlying genetic quality, possibly including physical attractiveness and intelligence, [ 95 ] or material resources that can enhance the survival ...
The pelvis is, in general, different between the human female and male skeleton. [12] [13] Although variations exist and there may be a degree of overlap between typically male or female traits, [12] [13] the pelvis is the most dimorphic bone of the human skeleton and is therefore likely to be accurate when using it to ascertain a person's sex ...
Most mammals, including humans, have an XY sex-determination system: the Y chromosome carries factors responsible for triggering male development. In the absence of a Y chromosome, the fetus will undergo female development. This is because of the presence of the sex-determining region of the Y chromosome, also known as the SRY gene. [5]
Mate preferences in humans refers to why one human chooses or chooses not to mate with another human and their reasoning why (see: Evolutionary Psychology, mating).Men and women have been observed having different criteria as what makes a good or ideal mate.

The human equivalent to the SDN-POA is the interstitial nucleus of the anterior hypothalamus, which is also sexually dimorphic and has demonstrated dissimilar sizes between sexualities. [ 6 ] [ 7 ] There are also other POA-like brain structures in the human brain which differ between sexual orientations, such as the suprachiasmatic nucleus and ...
