Green tea might lower testosterone levels and boost aromatase, but it is great for you! If you are worried though you should take a test booster.

Abstract
This study investigated the acute effects of green tea extract (GTE) and its polyphenol constituents, (-)-epigallocatechin-3-gallate (EGCG) and (-)-epicatechin (EC), on basal and stimulated testosterone production by rat Leydig cells in vitro. Leydig cells purified in a Percoll gradient were incubated for 3 h with GTE, EGCG or EC and the testosterone precursor androstenedione, in the presence or absence of either protein kinase A (PKA) or protein kinase C (PKC) activators. The reversibility of the effect was studied by pretreating cells for 15 min with GTE or EGCG, allowing them to recover for 1 h and challenging them for 2 h with human chorionic gonadotropin (hCG), luteinizing hormone releasing hormone (LHRH), 22(R)-hydroxycholesterol or androstenedione. GTE and EGCG, but not EC, inhibited both basal and kinase-stimulated testosterone production. Under the pretreatment conditions, the inhibitory effect of the higher concentration of GTE/EGCG on hCG/LHRH-stimulated or 22(R)-hydroxycholesterol-induced testosterone production was maintained, whereas androstenedione-supported testosterone production returned to control levels. At the lower concentration of GTE/EGCG, the inhibitory effect of these polyphenols on 22(R)-hydroxycholesterol-supported testosterone production was reversed. The inhibitory effects of GTE may be explained by the action of its principal component, EGCG, and the presence of a gallate group in its structure seems important for its high efficacy in inhibiting testosterone production. The mechanisms underlying the effects of GTE and EGCG involve the inhibition of the PKA/PKC signalling pathways, as well as the inhibition of P450 side-chain cleavage enzyme and 17beta-hydroxysteroid dehydrogenase function.

Abstract
Green tea (GT) and its components have been shown to possess antiobesity properties and the corresponding mechanisms of action are being investigated, given the epidemic proportions of obesity incidence. In the current work, we used 12-mo-old male Wistar rats to test the effect of 6 mo of treatment with GT as the sole drinking beverage (52.8 +/- 6.4 mL/d) on adipose tissue (AT). AT aromatase expression was determined by Western blotting, plasma concentrations of 17beta-estradiol and testosterone were determined by RIA, and adipocyte size determined by measuring diameter in tissue sections. Proliferation and apoptosis were also assessed by Ki67 immunostaining and terminal deoxynucleotidyl transferase-mediated deoxyuridine triphosphate nick end-labeling, respectively. Evaluations were made in subcutaneous (sc) AT and visceral (v) AT. Body weight increased over time in both groups (P < 0.001), but the increase was more pronounced in controls (P < 0.001) and food and fluid intake did not influence that effect. At the end of the experiment, aromatase expression increased in the AT (318.5 +/- 60.6% of control in scAT, P < 0.05, and 285.5 +/- 82.9% of control in vAT, P < 0.01). AT of GT-treated rats had a higher percentage of proliferating cells (204.1 +/- 19.5% of control in scAT, P < 0.01, and 246.6 +/- 50.2% of control in vAT, P < 0.01) and smaller adipocytes (78.3 +/- 1.7% of control in scAT, P < 0.001, and 87.9 +/- 3.2% of control in vAT, P < 0.05). GT also increased the number of apoptotic cells in vAT (320.4 +/- 21.9% of control; P < 0.001). These results suggest new mechanisms for GT on body weight and highlight its potential benefit to prevent or treat obesity and the metabolic syndrome.

at my doctors office there is a TV that plays random clips from TV shows and medical info bits & pieces to keep people in the waiting room from going insane from the long wait...
anyhow... one of the medical clips they played was from some early morning daily TV show and it had a nutritionist being interviewed about healthy foods/drinks to consume on a regular basis to lower your risk of cancer and other conditions... and the nutritionist said there was a study done that shows women who drink 3 cups of green tea a day have around a 35% lower risk of developing breast cancer... and while i'm sure most people on this site are men (me included) green tea consumption must have some implications for reduction in cancer risk for men as well, i'd imagine.
so 3 cups a day is what i heard in this one study. i'd say you probably can't hurt yourself by having TOO much although a french writer in the 1800's OD'd on caffeine from drinking 33 cups of coffee/tea in 1 hour...lol so don't do THAT much...

Nice. I used to drink it but it gave me a terrible sore throat and made me feel ill. My body just didn't agree with it at all. Sucks for me I guess.

So it has all these benefits, but it also might accelerate male pattern baldness? Also 1,2,8,9,10 n your fact sheet, have moreso to do with fighting the damage that fast acting sugar does to the body. HDL and LDL aren't even cholesterol. Lowering your cholesterol levels when they need to be up for repairing artery/cell damage could also be a bad thing. especially if you have a ton of sugar in your blood. It should really be stated that reducing sugar intake with regular green tea will increase overall health.

Along with all the benefits listed up to this point, green tea is also very good for gastric problems, such as Gastritis when caused by the Helicobacter Pylori bacteria, present in the gastrointestinal tract of over 50% of the world's population. To those responsive to the bacteria's effects, green tea helps against GERD by reducing inflammation of the stomach lining.

i drink it everyday.. one cup
I think it's good to try different brands and flavors till you get one you can slurp down. The more you drink of it the more accustomed you get too the flavors. It's no half as bad after a while. It may be good for you too esp in moderation. Eat and drink Everything in moderation
