Found the following bits interesting, maybe something we can somehow measure via bloodtests to see how far off we are after Finasteride usage:
Estrogen production in males is mainly from the peripheral conversion of androgens (testosterone and androstenedione) through the action of the enzyme aromatase, mainly in muscle, skin, and adipose tissue in the forms of estrone and estradiol.
The normal production ratio of testosterone to estrogen is approximately 100:1. The normal ratio of testosterone to estrogen in the circulation is approximately 300:1.
Treatments (more listed in the above link):
Clomiphene, an antiestrogen, can be administered on a trial basis at a dose of 50-100 mg per day for up to 6 months. Approximately 50% of patients achieve partial reduction in breast size, and approximately 20% of patients note complete resolution. Adverse effects, while rare, include visual problems, rash, and nausea.
Tamoxifen, an estrogen antagonist, is effective for recent-onset and tender gynecomastia when used in doses of 10-20 mg twice a day. Up to 80% of patients report partial to complete resolution. Tamoxifen is typically used for 3 months before referral to a surgeon. Nausea and epigastric discomfort are the main adverse effects.
Danazol, a synthetic derivative of testosterone, inhibits pituitary secretion of LH and follicle-stimulating hormone (FSH), which decreases estrogen synthesis from the testicles. The dose used for gynecomastia is 200 mg twice a day. Complete resolution of breast enlargement has been reported in 23% of cases. Adverse effects include weight gain, acne, muscle cramps, fluid retention, nausea, and abnormal liver function test results.
Hypo, perhaps you can comment about your claim Danzol reduces SHBG? If Danazol inhibits LH/FSH as they state above, is this not a problem for us when it comes to blunting our Testosterone/sperm production?
