Which is/are true concerning the development of the external genitalia?
| a. |
The clitoris and the penis both arise from the same embryonic structure |
|
| b. |
The male urethra and the female labia minora arise from the same embryonic structure |
|
| c. |
Many male structures form in the presence of testosterone and anti-Mullerian hormone, while many female structures form in the absence of these two hormones. |
|
| d. |
The labia majora and the scrotum both arise from the testis |
Genitalia is defined as the reproductive or sexual organs in males or females. They can be located internally or externally, depending on their function.
The clitoris and the penis both arise from the same embryonic structure because the genital tubercle will become the head or glans of the penis or the glans clitoris.
Therefore, option (a) is correct.
Many male structures form in the presence of testosterone and anti-Mullerian hormone. In contrast, many female structures form in the absence of these two hormones because male structures require testosterone for Wolffian ducts survival and anti-mullerian hormone to remove the Mullerian duct, a female characteristic. In contrast, females do not require these hormones for structural development.
Therefore, option (c) is correct.
