A primary response by the Leydig cells in the testes to the presence of luteinising hormone is an increase in the synthesis and secretion of ________.

Question

Quizplus · Accepted Answer

Luteinising hormone stimulates the Leydig cells in the testes to increase the synthesis and secretion of testosterone, which is responsible for the development and maintenance of male sexual characteristics. Inhibin is also produced by the Leydig cells, but it acts as a negative feedback mechanism to regulate the secretion of follicle-stimulating hormone (FSH) from the pituitary gland. Oxytocin and progesterone are not produced by the Leydig cells in the testes.
