These drugs should not be used with certain other medications, including nitroglycerin. When taken with nitroglycerin, a man's blood pressure can become dangerously low. Some men have died after taking these drugs with nitroglycerin.
Erectile Dysfunction Research: An Overview
Patients who express a loss of libido, depression, or any signs of diminished secondary sexual characteristics should have an endocrine evaluation that consists of at least measuring morning serum testosterone levels. The relative merits of measuring total, free, and bioavailable testosterone levels and serum hormone–binding globulin are controversial. At this time, measuring total and free testosterone levels is recommended and should be performed when screening for hypogonadism. These hormone levels are generally higher in the morning than later in the day; therefore, a morning level should be checked whenever possible. Free or bioavailable testosterone is an important component because this is the testosterone that is usable. That portion attached to other proteins, the serum hormone–binding globulins, store testosterone.

The end result: The couple can stop communicating altogether -- not only in the bedroom, but in all aspects of their relationship. And that, say experts, can only make problems worse for both partners.

To exert a measurable antitumor effect, tumor-specific T cells must be present in sufficient numbers and capable of trafficking to their targets. A direct correlation exists between the number of tumor-infiltrating lymphocytes (TILs) and a favorable clinical outcome, as demonstrated in patients with metastatic ovarian cancer (20). Furthermore, the functional status of TILs has been correlated with a favorable prognosis in various human malignancies (20–24). Because PDE5 inhibition augments antitumor immunity, we asked whether sildenafil treatment altered both the number and activation state of TILs. Histological examination of CT26WT tumors revealed a greater intratumoral cellular infiltrate in the sildenafil-treated mice compared with the untreated controls (Fig. 4 A). To better evaluate these differences, C26GM-bearing mice received either tumor-primed or no T cells followed by sildenafil treatment or no additional therapy. The tumors were excised 9 d later, and single cell suspensions were obtained. The T cell infiltrate was analyzed by flow cytometry for CD4+ and CD8+ T cells. This approach enabled us to accurately examine the entire tumor mass and reliably quantify the infiltrating lymphocytic population. Although no increase in CD4+ T cells was observed with PDE5 inhibition (Fig. 4 B, inset), sildenafil treatment greatly increased CD8+ intratumoral infiltration with up-regulation of the activation markers CD69 and CD25 (Fig. 4 C). There were no differences in activation markers between the sildenafil-treated group and sildenafil + ACT, whereas a significant increase in intratumoral T cells were observed in the sildenafil + ACT–treated group compared with sildenafil alone (Fig. 4 B and Fig. S4, available at http://www.jem.org/cgi/content/full/jem.20061104/DC1).
For example, television advertisements for Cialis, Levitra and Viagra have changed the perception of what it is to be a normal, healthy man, Metzl said. In that way, male sexual performance has been "medicalized."

Still, I wanted to learn more from news sites. Maybe they had articles out that Google News hadn’t picked up. So I headed over to CNN.

WEDNESDAY, Nov. 11 (HealthDay News) -- Exposure to high levels of the controversial plastics chemical bisphenol A (BPA) significantly raised the risk of sexual dysfunction, including impotence and low sex drive, among Chinese factory workers, a new study has found.
Obtaining erections which are either not rigid or full (lazy erection), or are lost more rapidly than would be expected (often before or during penetration), can be a sign of a failure of the mechanism which keeps blood held in the penis, and may signify an underlying clinical condition, often cardiovascular in origin.
Dynamic infusion cavernosometry: This test is used for men with ED who have a venous leak. During this test, fluid is pumped into the penis at a predetermined rate. By measuring the rate at which fluid must be pumped to attain a rigid erection, doctors can determine the severity of the venous leak.
