Study Notes
Development of Genitalia
- Wolffian duct develops into internal male genitalia in XY individuals
- Müllerian duct develops into internal female genitalia in XX individuals
- Mesonephric duct develops into male internal structures (except prostate) in XY individuals
- Paramesonephric duct develops into female internal structures
Regression of Ducts
- Müllerian duct regresses into a remnant called Gartner duct in females
- Paramesonephric duct regresses in XY individuals due to the action of Müllerian inhibitory factor (MIF)
Hormones and Factors
- Leydig cells secrete androgens that stimulate the development of mesonephric ducts
- Sertoli cells secrete Müllerian inhibitory factor (MIF)
- 5α-reductase deficiency results in undersized genitalia and prostate gland
Syndromes and Anomalies
- Mayer-Rokitansky-Küster-Hauser Syndrome: main characteristic is the absence of the uterus and vagina
- Uterine (Müllerian duct) anomalies: can cause infertility, recurrent miscarriage, and premature birth
- Common treatment for septate uterus is surgery to remove the septum
Formation of Cleft Lip and Palate
- Frontonasal prominence is involved in the formation of cleft lip
- Palatal shelves are involved in the formation of cleft palate
- The secondary palate forms from the palatal shelves
Development of External Genitalia
- Genital tubercle is part of the male external genitalia
- Ovary is part of the female internal genitalia
Genes and Development
- SRY gene on the Y chromosome leads to testes development
- Default development in the absence of the SRY gene leads to female internal genitalia
- In the presence of the SRY gene, male development occurs
