The infant shape is usually oval which helps it slide through the female pelvis during birth.
A human female's pelvis is wider; a male's pelvis is narrower. The wider pelvis assists if a female becomes pregnant, because hormones allow ligaments to relax, which further widens the pelvic outlet. This allows the baby's head and shoulders more room to pass through the pelvic bones as the infant enters the vaginal canal.
The head of the femur articulates with the os coxa (pelvis) at the acetabulum. The acetabulum is the rounded socket that the head of the femur fits into. It also allows sliding of the pelvic bones and rotation. This joint is a synovial joint and is an example of a "ball-and-socket" joint.
* deep socket in the coxal bone* formed where the ilium, ischium, and pubis bones fuse* the head of the femur, the thigh bone, fits in the acetabulumAcetabulum is the area on the pelvis where the head of the femur joins the pelvis. It is a concave surface that allows for the forming of the hip joint which allows you kick your leg up.The hip has these two bowl shaped regions into which the upper femur fits. This is the hip joint. That bowl shaped region is called the acetabulum.
The cup-shaped depression on the hip join that receives head of the femur is the acetabulum.
The pelvis is made up of three bones; the ilium, the ischium, and the pubic bone. Attached to the back of the pelvis is the sacrum/coccyx which are two bones made of multiple vertebrae that are fused together. Also connected to the pelvic bone is the head of the femur (thigh bone) which sits in the acetabulum of the pelvis and creates the acetabulofemoral joint also known as the hip joint.

The pelvis is the part of the skeleton whose anatomy is most deifferent between sexes. The average male pelvis is much more heavier and thicker than the female's. This is due to the forces exerted on the bones by stronger muscles. The female pelvis is adapted for pregnancy and childbirth. It is much wider and shallower and has a larger pelvic inlet and outlet, which allows passage for the infants head during childbirth. The female's pelvis is also tilted foward while the male's is relatively vertical.Collapse Replies
The female pelvis is shaped like a bowl with the bottom cut off. The top of the pelvis is called the brim and the bottom is called the outlet. Towards the end of pregnancy the part of the baby which is born first (hopefully the head) settles into the pelvis. This is called engagement Relation to brim describes how much of the head can be felt above the pelvis. It is usually measured in fifths. 5/5 means that no part of the head is in the pelvis. 4/5 means that the top part of the head is in the pelvis and so on. By the time the head is 0/5 the baby is almost born at the end of labor. If at the end of a first pregnancy the midwife or ob/gyn can still feel 5/5 of the baby's head it may mean that the baby is too large to be born naturally. With second or later babies the head may not go into the pelvis until the mother goes into labor.

The pelvis is the first bone anthropologist look at because a male can not fit a human head through their pelvis. A female (the one that is pregnant) can fit a babies head through her pelvis because its wide enough and doesnt have anything blocking where the baby comes out at.
A woman's pelvis is shaped like a bowl with the bottom cut off where the top of the pelvis is known as the brim and the bottom is the outlet. At the end of the pregnancy the head of the baby (or w/e part born first) is settled into the bottom of the pelvis. Relation to the brim describes how much of the head can be felt above the pelvis. This is measured in fifths (1 out of 5, 2 out of 5, 3 out of 5 etc). When it's 5 out of 5 it means that no part of the head is in the pelvis and 4 out of 5 means that the top of the head is in the pelvis etc. So your baby's head is halfway. When it's 0 out of 5 the baby is almost born.
Mainly the hip bones which are lower and wider in females. The pelvis has a wider opening to allow for a child's head to pass during birth. Also, females have smaller and more rounded shaped bones then males. The bones of males tend to have more prominences on them, like jaws are more square and eyebrow ridges are more pronounced. Men and women, contrary to popular belief, have the same number of ribs. See the Related Links for "www.bartleby.com: The Pelvis" to the bottom for the answer. For information on ribs and proof that men and women do have the same number, you can go to http://biology.clc.uc.edu/Courses/bio105/ribs.htm.
Nothing you fat head
When a guy moves his head from resting on your knee higher to you thigh, then your pelvis, he is being suggestive, and stop him if you are uncomfortable with it.
The acetabulum is a concave surface of the pelvis. The head of the femur meets with the pelvis at the acetabulum, forming the hip joint
