A Anterior lobe of pituitary
FSH (Follicle stimulating hormone) is produced by basophilic cells of anterior lobe of pituitary gland.
In females, it stimulates growth of ovarian follicles until ovulation occurs.
In males, it stimulates development of seminiferous tubules and spermatogenesis i.e. formation of sperms from germ cells.
So, the correct answer is 'Anterior lobe of pituitary'.
