CONCLUSION
Testicular histology and serum GnRH, LH and FSH levels can further help in arriving at a clear-cut conclusion. At this stage, the only conclusion is that the amlodipine causes a significant drop in absolute testicular weight, GSI and serum testosterone levels. Whether the reduction in absolute testicular weight and GSI has been caused by suppressed testosterone levels or vice versa, that needs to be further determined.[B\]
Man, good info. I am on 140mg of test now, but I do not like that that it causes a significant drop in absolute testicular weight, GSI and serum testosterone levels.
I am taking 5mg norvasc and 10mg quinapril. MY BP is fine now. I will need to see about coming off, at least the norvasc.
Thanks for the info.
