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 ...
This list of related male and female reproductive organs shows how the male and female reproductive organs and the development of the reproductive system are related, sharing a common developmental path. This makes them biological homologues. These organs differentiate into the respective sex organs in males and females.
The female pelvis is lighter and thinner than the male pelvis. [11] The female inlet is larger and oval in shape, while the male sacral promontory projects further (i.e. the male inlet is more heart-shaped). [10] The sides of the male pelvis converge from the inlet to the outlet, whereas the sides of the female pelvis are wider apart. [12]
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] Thus, male mammals typically have an X and a Y chromosome (XY), while female mammals typically have two X chromosomes (XX).
A subpubic angle of 50–82 degrees indicates a male; an angle of 90 degrees indicates a female. [2] Other sources operate with 50–60 degrees for males and 70–90 degrees in females. [1] Women have wider hips, and thus a greater subpubic angle, in order to allow for child birth.
The Phenice method is a technique of determining the sex of a human skeleton from the innominate pelvis. In the procedure, sex is determined based on three features: the ventral arc, the subpubic concavity, and the medial aspect of the ischio-pubic ramus. As a non-metric absolute method, it relies on the recognition of discrete male and female ...
The pelvic cavity is a body cavity that is bounded by the bones of the pelvis. Its oblique roof is the pelvic inlet (the superior opening of the pelvis). Its lower boundary is the pelvic floor. The pelvic cavity primarily contains the reproductive organs, urinary bladder, distal ureters, proximal urethra, terminal sigmoid colon, rectum, and ...
Sexual differentiation is the process of development of the sex differences between males and females from an undifferentiated zygote. [1] [2] Sex determination is often distinct from sex differentiation; sex determination is the designation for the development stage towards either male or female, while sex differentiation is the pathway towards the development of the phenotype.
