desbalanço hormonal

Andei dando uma lida, que só é possivel a prolactina subir, se o estrogeno estiver presente, confere?

Não, acredito que tenha lido que só é possível ter problemas como uma ginecomastia com prolactina se o estrogenio estiver presente.

Mas prolactina subir indepente do estrogeno.

Basicamente , vc acumula gordura qd tem estrogenio alto , sem estrogenio as chances da ginecomastia aparecer é bem baixa , se for letro ou exemest eu diria impossivel , ai qd vc para q vem a surpresa rsrs

Então, tinha lido o mesmo a respeito, mais achei esse artigo no Steroid Fórum, vou procurar e postar...

PROGESTERONE AND PROLACTIN INDUCED GYNECOMASTIA

Before delving into this subject, I’d like to say first and foremost, that in users of anabolic /androgenic steroids (AAS) the first step in combating the development of gynecomastia, or male breast enlargement, is to eliminate the causative agent: the anabolic steroid . Drug-induced gynecomastia almost invariably resolves on its own when a person quits taking the drugs responsible for it, if caught before permanent fibrosis develops. Unfortunately, most AAS users don’t want to employ this simple approach, for obvious reasons, so the foregoing will all be under the assumption that a person wants to prevent or treat gyno and still continue steroid use .

In the belief that certain anabolic steroids increase prolactin levels as well as act as agonists at the progesterone receptor, some have advocated the use of antiprolactin agents, like bromocriptine, or progesterone receptor blockers like RU-486 to treat AAS related gynecomastia, in lieu of more traditional drugs like tamoxifen .

In truth, the etiology of gynecomastia is unknown and a number of agents including estrogens, progestins, GH, IGF -1, and prolactin may be involved. However, most authorities believe that a decreased (T+DHT)/E ratio is central to the development of gyno, and that blocking the effects of estrogen, or increasing T + DHT levels, is central to ameliorating the problem.

Regarding prolactin, androgens decrease prolactin levels whereas estrogens increase prolactin. Non-aromatizing androgens have never been shown to elevate prolactin levels in humans, but testosterone has, due to its aromatization to estradiol (19). Prolactin secreting tumors, or prolactinomas, are often associated with gyno. But in these cases the prolactin is believed to induce gyno by suppressing testosterone production: “Prolactinomas that are sufficiently large to cause gynecomastia do so as a result of impairment of gonadotropin secretion and secondary hypogonadism”. (20). However, this is a moot issue in AAS users whose gonadotropin secretion is already blunted.

According to research cited in (20), prolactin may have a direct stimulatory effect on mammary tissue development, but only in the presence of high estrogen levels:

The presence of mild hyperprolactinaemia is therefore not uncommon in patients with estrogen excess. Significant primary hyperprolactinaemia, on the other hand, may directly stimulate epithelial cell proliferation in an estrogen-primed breast, causing epithelial cell proliferation and gynaecomastia.

So rather than focusing solely on lowering prolactin levels which may be elevated in users of aromatizing androgens, attacking estrogen should be the first line of action.

GH and IGF-1 are considered critical to the proliferation of mammary tissue. An excellent review of the role played by these hormones, as well as a general overview of gynecomastia can be found here:

Since elevated GH and IGF-1 are considered important to the anabolic effect of AAS, it would be impractical and counterproductive to attempt to prevent gynecomastia by blocking GH/IGF.

Progesterone acts in concert with estrogen to promote breast development, and at least part of any role played by synthetic progestins may be to stimulate IGF-1 production in the breast. But again, blocking the action of progesterone or synthetic progestins is not practical. Specific progesterone receptor antagonists like RU-486 block not only the progesterone receptor, but the androgen receptor as well, and have actually been associated with the development of gynecomastia (21). In any case, progesterone is thought to act on the breast to enhance the effects of estrogen (22) so once again, attacking estrogen is the easiest and most logical approach.

DHT gel (Andractim) or a generic knockoff might help as well. DHT is thought to act as an aromatase inhibitor (23) and perhaps compete directly with estrogen for binding at the estrogen receptor (24). DHT has been used in several case reports and controlled trials to successfully treat gynecomastia. So perhaps a viable strategy would be to combine DHT gel with tamoxifen. I would recommend tamoxifen rather than an aromatase inhibitor due to the simple fact that tamoxifen has been widely used in numerous controlled studies to succesfully treat gynecomastia, whereas the evidence to support the efficacy of aromatase inhibitors is scanty at best.

Então, tinha lido o mesmo a respeito, mais achei esse artigo no Steroid Fórum, vou procurar e postar...

Isso, esse texto ta dizendo o que eu falei.

O fator limitante para se ter uma ginecomastia parece ser o estrogeno. se tiver com a prolactina bem alta, mas com o estrogeno bem baixo, vc não terá.

Mas isso não significa que a prolactina só irá subir se os estrogenos subirem.
