Leydig cells of fetus testis secretes
a) hCG
b) LH
c) Testosterone
d) Mullerian inhibiting substance
Correct Answer - C
Answer- C. Testosterone
Leydig cells in fetal testis are the cellular site of testosterone
synthesis.
Fetal testis also secretes mullerian inhibiting substance produced by
sertoli cells which acts locally as a paracrine factor to cause
mullerian duct regression. Mullerian duct regression completes by 9
to 10 weeks’ gestation, which is much before testosterone secretion
has commenced.
