The gonadotropins, FSH and LH, are heterodimeric glycoprotein hormones released in pulses from the pituitary gonadotrope cells. FSH and LH secretion is regulated by hypothalamic GnRH, which itself is pulsatile.GnRHâsecreting neurons originate in the olfactory placode and migrate to the hypothalamus during development; defects affecting neuronal migration can be associated with a lack of smell (anosmia).he gonadotropins, FSH and LH, are heterodimeric glycoprotein hormones released in pulses from the pituitary gonadotrope cells.
