Now with all these side effects they are finding with use in women, who is to tell what it is doing to us men, besides some bogus studies done in Hong Kong????

Gynecomastia. A bothersome but readily treatable problem.

Although breast enlargement in boys and men can cause both psychological and physical distress, the disorder is rarely serious and is readily treatable. Several factors can lead to the estrogenic excess that causes growth of breast tissue.
Dr Jacobs describes a patient with gynecomastia related to cirrhosis of the liver who responded promptly to a brief course of tamoxifen citrate therapy..

OBJECTIVES: Current therapies for advanced prostate carcinoma lead to a marked decrease in serum testosterone levels, which renders patients impotent. In preliminary studies, combination therapy with flutamide and finasteride has been used as an alternative therapy for the treatment of prostate carcinoma because potency can be preserved. Both of these agents can cause gynecomastia and breast/nipple tenderness. METHODS: Six men being treated for advanced prostate carcinoma with flutamide/finasteride combination therapy developed painful gynecomastia, which was treated with tamoxifen 10 to 30 mg/day for 1 month. Clinical follow-up included breast measurements and determination of prostate-specific antigen (PSA), testosterone, and estradiol levels. RESULTS: While on this
combination therapy for prostate carcinoma, 4 of 6 patients experienced a decrease in PSA level to less than 0.5 ng/mL. All patients remained potent. Serum testosterone increased in each patient who had a baseline level drawn. Estradiol levels were noted to be elevated in 4 of 6 patients at the time of evaluation for gynecomastia. After treatment with tamoxifen, circulating estradiol levels increased in 3 patients from 1.3 to 2.2 times the baseline level. .
Five patients experienced complete resolution of breast and nipple pain on tamoxifen 10 mg/day within the first month. The other patient had to be treated with 30 mg/day for 1 additional month, which subsequently resulted in pain resolution. . CONCLUSIONS: These preliminary results suggest that low-dose tamoxifen is useful in treating painful gynecomastia for those patients on flutamide/finasteride combination therapy for advanced prostate carcinoma.

[Testosterone and estradiol levels in male gynecomastia. Clinical and endocrine findings during treatment with tamoxifen]
[Article in German]

Oestradiol-(E2) levels in serum were significantly higher in a group of 91 males with gynaecomastia than in a control group. The levels were highest in patients with testicular tumour, hyperprolactinaemia and idiopathic gynaecomastia. In gynaecomastia of puberty and primary or secondary hypogonadism, the E2 level was within normal limits, but the testosterone/oestradiol ratio was significantly reduced. Tamoxifen, at a daily dose of 20 mg, was administered over 2-4 months to 16 patients with gynaecomastia. Of twelve patients with painful gynaecomastia ten became painfree. .
Gynaecomastia regressed partially or completely in 14 patients, in only 2 was it unchanged. There was no recurrence of gynaecomastia after discontinuing tamoxifen. Side-effects did not occur. It is concluded that tamoxifen is a promising alternative to the surgical treatment of gynaecomastia.
I could go on, but I think the point has been made.
BTW, I guess I should throw out my tren because it "does not have FDA approval for use in humans" and has some side effects.
