The nurse knows that if which of the following hormones listed below are not available during embryonic development, a male embryo with an XY chromosomal pattern may develop female external genitalia?
Select all that apply.
A)
Anti-Müllerian hormone (AMH)
B)
Testosterone
C)
Dihydrotestosterone (DHT)
D)
Acrosome
E)
Follicle-stimulating hormone (FSH)
Ans:
B, C
Feedback:
In the absence of testosterone (and DHT), a male embryo with an XY chromosomal pattern develops female external genitalia. AMH suppresses the Müllerian ducts and prevents development of the uterus and fallopian tubes in the male. Acrosome is the outside of the anterior two thirds of the head of a sperm. For spermatogenesis to occur, FSH binds to specific receptors in Sertoli cells.
