Select the incorrect statement

LH is a Luteinizing hormone produced by the gonadotropic cells in the anterior pituitary gland. It plays an important role in puberty, menstruation, and fertility. It triggers ovulation and development of the corpus luteum. In male, LH triggers the secretion of androgen called as testosterone from the Leydig cells. FSH is follicle-stimulating hormone produced by gonadotropic cells in the anterior pituitary gland. It helps in regulation of development, growth, pubertal maturation and reproductive processes of the body. It stimulates the Sertoli cells of the testicles and helps in spermatogenesis, production of sperm.  During the follicular phase, the LH and FSH increase gradually. They stimulate follicular development and estrogen secretion by follicular cells.

Thus, the correct answer is 'LH and FSH decrease gradually during the follicular phase.'
