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.GnRHâsecreting 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.
