Which hormone is not produced by the anterior lobe of the pituitary gland?

The hormone that is not produced by the anterior lobe of the pituitary gland is testosterone. Testosterone is actually produced primarily in the testes in males and in smaller amounts in the ovaries and adrenal glands in females. It is a steroid hormone responsible for the development of male secondary sexual characteristics and reproductive functions.

In contrast, the hormones that are produced by the anterior lobe of the pituitary gland include luteinizing hormone (LH), follicle-stimulating hormone (FSH), and prolactin. These hormones play crucial roles in regulating various bodily functions, such as the menstrual cycle, ovulation, and milk production in females. The anterior pituitary is responsible for synthesizing and secreting these hormones in response to signals from the hypothalamus.
