Alow secretion of luteinizing hormone (lh) in the normal male adult would cause a low secretion of luteinizing hormone (lh) in the normal male adult would cause shrinkage of the anterior pituitary gland excessive beard growth increased spermatogenesis decreased testosterone secretion

The correct answer is "decreased testosterone secretion"

Luteinizing hormone is a hormone primarily produced in the anterior pituitary gland that stimulates the Leydig cells in the testes of human males. In stimulation of the Leydig cells, there will be an increase in testosterone secretion. This means that low levels of luteinizing hormones will lead to a decreased testosterone secretion.
