An 18-year-old has not yet had her menses. She has normal pubic hair, and an ultrasound shows an absent uterus but normal ovaries. What is the most likely karyotype?
A. 46XX
B. 46XY
C. 45X
D. Mosaicism
The correct answer is:
B. 46XY
Explanation:
The presence of normal secondary sexual characteristics (such as pubic hair) combined with the absence of a uterus but normal ovaries on ultrasound suggests Androgen Insensitivity Syndrome (AIS). AIS is a condition where an individual has a 46XY karyotype but is resistant to androgens, leading to the development of female external genitalia despite having male (XY) chromosomes. The absence of a uterus occurs because the Müllerian ducts regress due to the presence of anti-Müllerian hormone (AMH) produced by the testes, which are typically undescended or located in the abdomen or inguinal region. The ovaries mentioned in the question could be a misinterpretation on ultrasound or might refer to streak gonads rather than functional ovaries.
