What are the types of Gynecoid pelvis?
Although pelvises can be classified according to diameter, in obstetric practice they are often divided into 4 main types: gynecoid, android, anthropoid, and platypelloid, based mainly on the shape of the pelvic inlet [5].
What are the four types of female pelvis?
The four types of female pelvis:
- The Gynaecoid or genuine female pelvis. It has an almost round brim and will permit the passage of an average-sized baby with the least amount of trauma to the mother and baby in normal circumstances.
- The Android pelvis.
- The Anthropoid pelvis.
- The Platypelloid pelvis.
Who has Platypelloid pelvis?
Some types are more common than others Then, there’s the heart-shaped or android pelvis (yep—just like the phone). About 25 percent of women have this type. Lastly, just 5 percent of women have a platypelloid pelvis, which is oval and has a wide pubic arch.
What is a Gynecoid definition?

What does Platypelloid pelvis mean?
a pelvis having an inlet with a transverse diameter that exceeds the anteroposterior diameter, the inlet thus appearing as a flat oval.
What is a Gynecoid Definition?
What are the features of Gynecoid pelvis?
The gynecoid pelvis is more delicate, wider than, and not as high as the male pelvis. The angle of the female pubic arch is wide and round. The female sacrum is wider than the male’s and the iliac bone is flatter. The pelvic basin of the female is more spacious and less funnel-shaped.
What is a Gynaecoid pelvis?
Gynecoid pelvis: The gynecoid pelvis is one that is generally characteristic of a woman in its bone structure and therefore its shape. Gynecoid means like a woman, womanly, female. The gynecoid pelvis is more delicate, wider than, and not as high as the male pelvis. The angle of the female pubic arch is wide and round.
What do you mean by Malpresentations and malposition?
Malpositions are abnormal positions of the vertex of the fetal head relative to the maternal pelvis. Malpresentations are all presentations of the fetus other than vertex.

What is Gynaecoid?
Gynecoid means like a woman, womanly, female. The gynecoid pelvis is more delicate, wider than, and not as high as the male pelvis. The angle of the female pubic arch is wide and round. The female sacrum is wider than the male’s and the iliac bone is flatter.
What causes Malpresentations?
Common causes of malpresentations/malpositions include: excess amniotic fluid, abnormal shape and size of the pelvis; uterine tumour; placenta praevia; slackness of uterine muscles (after many previous pregnancies); or multiple pregnancy.
What is the difference between Anthropoid and gynecoid pelvis?
An anthropoid pelvis is, like the gynecoid pelvis, basically oval at the inlet, but the long axis is oriented vertically rather than side to side.Subpubic arch may be slightly narrowed. This pelvis favors occiput posterior presentations. Pelvic brim is an anteroposterior ellipse, Gynecoid pelvis turned 90 degrees, Narrow ischial spines.
What is the classification of gynecoid pelvis?
Caldwell-Moloy Classification Gynecoid Pelvis (50%) Pelvic brim is a transverse ellipse (nearly a circle) Most favorable for delivery. Android Pelvis (Male type) Pelvic brim is triangular. Convergent Side Walls (widest posteriorly) Prominent ischial spines. Narrow subpubic arch.
How common is the anthropoid pelvis?
Much more common in black women The anthropoid pelvis is very long and almost “ovoid” in shape. It is more common in non-white females (it makes up about 25% of pelvic type in white women and close to 50% in non-white women).
How does the anthropoid pelvis affect delivery?
The anthropoid pelvis tends to keep the baby in an occiput posterior position. This means that the baby is looking up toward the ceiling. This position is harder to deliver, as the baby would have to extend its neck to come out, rather than flex its neck.
