unable to ejaculte after heart surgury August 2009

I had heart surgury in August 2009 for repair of two heart valves. Since then I have have a lack of stamina and get tired easily. My doctors told me to expect these symtoms (symptoms) to last up  to a year.
I am currently using a penis injection mix that provides an erection for up to 90 minutes with success.
If I use a male enhancement product fot two days, I can ejaculate by masturbation only.Even then it is watery  and only moderate volume.
I have been taking Volume plus tabs. for 5 weeks now with no  response.I have just been in to see my Uroligist last week. He did not see why I should be concerned about that and offered no or any helpfull advise. He did not have any positive response on the Volume Plus tabs? Before my surgury and symtoms (symptoms) leading up to I had much more ejaculate seman and certainly thicker as normal again only through masterbation (masturbation)? Is my problem related to my heart surgury? and  will it return to normal. Any suggestions will be helpfull.
in time? Are their any other alternatives to help my condition?

Ejaculatory volume (and force) varies with age, extent of sexual excitement, time from last ejaculation, prostate changes, neurological issues and from individual to individual. Many men are not concerned with the volume, but obviously you are. Unfortunately, there is little of which I am aware that a man can do from the standpoint of medication or diet that can influence this volume. I am quite skeptical, to say the least, of the herbal medication that you have been taking. If there were some published statistics in peer reviewed journals that support their claims, then I'd feel more disposed to trust what they say.
I do not see your problem as related to your heart surgery. There may be some effect from one of the medications that you are using. I would suggest that you have your total testosterone and thyroid function checked. If your TOTAL testosterone is low, then a prolactin level, sex hormone binding globulin level and repeat total testosterone level would be indicated. Free testosterone levels are quite unreliable, so I would not obtain that.
There are testosterone supplements (not pills) that can be prescribed if your levels are low.

Dr. I forgot to mention I am a 65 year old white male in good health. I have clear arteries and excellent cholestrol  numbers. I am taking two meds for chlosterol and two meds for high blood pressure.

is their things in my diet that can contribute to the problem. i heard soft drinks can reduce sperm counts?
