    high estradiol question

    Do i have high risk of gynecomastia from finasteride?
    Before start taking finasteride i checked my hormonal level: everything is within normal range except estradiol : 234,3 (normal for man: 0-206).

    3 weeks on 0,33mg fin for now and have no problem(maybe only watery semen).

    Before that i've taken 1mg finasteride in april about 1 week. Canceled due ball ashe and probably prostate pain.

    I'd say you're already at risk for gyno. Taking an anti-androgen isn't going to help.

    With estrogen levels that high you should only take finasteride under a doctor's supervision.

    Re: high estradiol question

    After 1 month on fin i checked my estradiol level again.
    And it's 493 pmol / L (normal range 0-206 pmol / L).
    Also i have got a bit of fat between the pectoral muscles and mammary gland (never got before!!).

    I think it's time to quit fin...what do u think?

    That sounds way too high to me. I would probably quit finasteride if I were you.

    If you have hair loss with estrogen levels that high than you probably have severe follicular sensitivity to androgens. Estrogen should help grow hair even on the hairline. It grows other things though...

    Re: high estradiol question - dangers & side effects of propecia

    The problem with FIN is that it only blocks free testosterone from converting to DHT. As a result the free T floating in your bloodstream starts cascading down into estradiol because it naturally wants to be converted into one of these hormones.

    That's why your hormonal system goes out of whack and taking Finasteride makes no sense to me. To keep your system in balance and prevent hair loss you must be able to also block the conversion of free T into estradiol and also block SHBG(Sex Hormone Binding Globulin) from binding to free T to make up for the lack of DHT in the body while using a DHT inhibitor. I would suggest getting off of Finasteride so you don't end up with the side effects that accompany high estrogen levels in men.

    You think T starts "cascading" down into estradiol, just from using finasteride? If that were really true, don't you think the FDA (and Merck) would have been up in arms about that possibility, when finasteride was first approved a long time ago?
    1) No, damnit, finasteride for hairloss was NOT an "accidental discovery".
    2) No, you do NOT have to use minoxidil and Retin-A at the same time.
    3) No, washing your skin does NOT make it produce more sebum.

    Yea, you and I would think Bryan, but we are not the FDA. You would think they would be "up in arms" with the listed side effects alone...

    You can find the warning straight from the Propecia website:
    "In addition, some men may have breast enlargement and/or tenderness. You should promptly report to your doctor any changes in your breasts such as lumps, pain, or nipple discharge."

    Gyno typically only occurs when estrogen levels are high in men like this particular poster and many other cases.
