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 pelvis must be orientated such that the observer is looking at the dorsal aspect of the pubis and ischio-pubic ramus. Phenice describes the subpubic concavity as ‘a lateral recurve which occurs in the ischio-pubic ramus… a short distance below the lower margin of the pubic symphysis.’ This is also only found in female examples.
These eminences are separated by three notches: one in front, the pubic arch, formed by the convergence of the inferior rami of the ischium and pubis on either side.; The other notches, one on either side, are formed by the sacrum and coccyx behind, the ischium in front, and the ilium above; they are called the sciatic notches; in the natural state they are converted into foramina by the ...
The sides of the male pelvis converge from the inlet to the outlet, whereas the sides of the female pelvis are wider apart. [12] The angle between the inferior pubic rami is acute (70 degrees) in men, but obtuse (90–100 degrees) in women. Accordingly, the angle is called subpubic angle in men and pubic arch in women. [10]
“The angle of entry and the pressure against the pubic bone can contribute to intense pleasure,” she says. How to do it: One partner will lie on their back, on a bed or table, with hips at the ...
The pubic bone is made up of a body, superior ramus, and inferior ramus (Latin: branch). The left and right coxal bones join at the pubic symphysis. It is covered by a layer of fat – the mons pubis. The pubis is the lower limit of the suprapubic region. In the female, the pubis is anterior to the urethral sponge.
The female pelvis has also evolved to be much wider and allow for greater room in order to safely deliver a child. After sexual maturation, it can be observed that the pubic arch in females is generally an obtuse angle (between 90 and 100 degrees) while males tend to have more of an acute angle (approximately 70 degrees).

The women who were able to orgasm more frequently tended to be older, had sex more often, and more often participated in the following positions: face to face with the woman on top, sitting face ...
