Hi can I get help with this question please? I am stuck!! Topic is sexual reproduction and its physiology. Scenario: Drew T. is a 22-year old man who has trouble producing sperm. The medical doctors identify that the problem is with the Luteinizing Hormone (LH) receptors on his Leydig cells. He comes to you confused because he thought it was the Sertoli cells that produced sperm. You explain to Drew…(see image)
Too much LH in the
system directly harms
sperm production
He is wrong, Leydig cells
are the production center
of sperm
YES
LH causes Leydig cells to
produce the testosterone
that is necessary for
sperm development
When LH doesn't bind to
Leydig cells, follicle-
stimulating hormone will,
and then there's less
follicle stimulating
hormone available for the
Sertoli cells
