Physiological Changes in Pregnancy
Puberty occurs later in boys than in girls due to all of the following except: (DNB, NOV 2009)
|A||increased level of inhibin|
|B||Decreased level of follistatin|
|C||decreased level of activin|
|D||None of above|
Decreased level of follistatin
“activin stimulates FSH secretion and inhibin inhibits it."
a. "Activin binds to a family of glycoproteins called as FOLL/STATIN and inhibits it"
b. Hence, it is the decreased level of activin which causes increased level of follistatin and thus delays puberty.
