Why doesn't testosterone inhibit both LH and FSH?

Why wouldn't testosterone inhibit both LH and FSH release if it inhibits GnRH release? Uworld says it doesn't multiple times and it isn't making sense to me. Thanks in advance!

It directly inhibits LH (feedback inhibition) but also inhibits GnRh. So yes it should inhibit both, but if given the choice between them I would def go for LH (direct inhibition). Can you provide a question ID for your claim?

I think only high levels of testosterone exhibit significant feedback on FSH, which is regulated more by inhibin.
