Development of the Sexual Organs in the Embryo and Fetus

4.8K
Development of the reproductive organs in an embryo starts from a bipotential state. This means the early embryo can develop either male or female reproductive organs. The formation of these organs begins with the growth of gonadal ridges that arise from the intermediate mesoderm during the fifth week of development.
Near the gonadal ridges, two duct systems are present: the mesonephric ducts (Wolffian ducts) and paramesonephric ducts (Müllerian ducts). These ducts form the basis for the...

Summary

The subpubic angle in human fetuses remains acute throughout development, with significant widening after 30 weeks of gestation. Sexual dimorphism is noted in early gestation, with females exhibiting a wider angle, similar to adults.

Area of Science:

  • Anatomy
  • Embryology
  • Radiology

Background:

  • The pubic bones form the symphysis pubis, with the inferior rami defining the subpubic angle.
  • The subpubic angle is typically >90° in females and <90° in males.
  • Limited data exists on fetal subpubic angle development.

Purpose of the Study:

  • To measure the fetal subpubic angle across gestational ages.
  • To determine if the subpubic angle is sex-dependent in fetuses.
  • To compare fetal subpubic angles with adult values.

Main Methods:

  • A cross-sectional study of 41 formalin-fixed human fetuses.
  • Fetuses were grouped by gestational age (14-18, 19-22, 23-26, 27-30, >30 weeks).
  • Radiological examination of dissected pubic symphyses was performed to measure the subpubic angle.

Main Results:

  • The subpubic angle ranged from 58°-64° throughout intrauterine life.
  • A significant increase in the subpubic angle was observed in fetuses >30 weeks.
  • Statistically significant sexual dimorphism was found in fetuses aged 14-22 weeks, with females having a wider angle.

Conclusions:

  • The subpubic angle is acute in fetuses, widening significantly after 30 weeks gestation.
  • Sexual dimorphism is evident in early fetal development (14-22 weeks), with females showing a tendency towards a wider angle.
  • Antenatal ultrasonography may aid in diagnosing symphysis pubis abnormalities.
