My husband, aged 61, has completely lost his libido. He is taking
testosterone gel at the increased dose and it is nort helping. He does
not feel that he is depressed. He has also developed a little bend in
his penis. I am concerned that our sex life is over because the
testosterone doesn't seem to be working. We have ruled out
anti-depressants and other meds. Help

When you say "we" I hope that includes a doctor who has done a
complete work up on your husband.  Does he sleep well or had a sleep
study test done?  If he finds it hard to wake up in the morning or is
tired during the day he may not be getting a good nights sleep which
can be a sleep disorder that may be affecting his drive.
If this is a big issue to you - and it appears it is - a sex therapist
may be in order if no problem is identified.

Testosterone is a male sex hormone that has a unique effect on a man's
complete physical attributes. It is produced in the testes and in the
adrenal glands. It is to males what estrogen is to females. It helps
to build protein and is essential for normal sexual behavior and
producing erections. It also affects many metabolic activities such as
production of blood cells in the bone marrow, bone formation, lipid
metabolism, carbohydrate metabolism, liver function and prostate gland
growth.

This question to be answered fully literally requires it's own text
book but I think I can give you several guides that will take you to
the right answer...

The testosterone creams can be absorbed at different rates in
different people.  Your doctor should do another blood level to make
sure that levels are adequate.  If not the dose should be increased
again or your husband  should be swapped to an injectable form of
testosterone (or he should go up again on the strength of the cream). 
An estrogen level should also be done to make sure not too high (I
like for testosterone to be 12 to 15 times higher than estrogen).

I'm also a big fan of prescription strength Yohimbine (Yocon).  This
was the drug of choice for erectile dysfunction before Viagra.  It
only improves firmness of erection in only about 20% but the effect of
libido can be great (I often prescribe it for my patients in
conjuntion with Viagra).

For much more on the question (there is much more to be said), go go
my web site (http://TempleRepair.com) and search under "libido &
erection."  I also make reference there to many articles in the
medical literature and a good article done by the NIH on the complete
evaluation of erectile dysfunction and libido.

Good luck.  Most people can be helped and there's a wide variation in
the skill of physicians in every area (including this one) so persist
with another physician if your husband does not improve with the one
he's seeing.
