As many of my readers know, the medical industry has been quietly increasing its interest in and clinical trials with so-called “neurosteroids”, most of them members of the pregnane family. I think the term “neurosteroid” as used by mainstream medicine is a misnomer as it is used selectively for only a few of all the known steroids, despite the fact that virtually all of them have been demonstrated to have a central (brain) effect. For example, currently the label “neurosteroid” is applied almost exclusively to steroids such as pregnenolone, progesterone, allopregnanolone and various of their synthetic derivatives, though steroid families such as estrogens, androgens, mineralo\/gluco-corticoids, and even thyroid hormones have all been demonstrated to have potent and rapid central effects as well, with indisputable influence on mood, cognition, various neurological conditions, traumas (e.g. TBI) and even cancer.<\/p>\n
Recently, the FDA approved the progesterone derivative allopregnanolone<\/a> (3\u03b1, 5\u03b1-tetrahydroprogesterone), commonly known as Allo or AlloP, as a treatment for post-partum depression. In addition, multiple companies are running clinical trials with that steroid for wide range of other conditions including dementia (e.g. Alzheimer Disease), anxiety disorders, autism, psychotic states (e.g. schizophrenia), post-traumatic stress disorder (PTSD), and even direct brain damage states such as traumatic brain injury (TBI) as well as its chronic form known as chronic traumatic encephalopathy (CTE). As of now, the only condition for which AlloP has been approved is postpartum depression with expectations that the steroid will soon be also approved for depression of any origin. The currently approved formulation is through IV infusion, but some of the new formulations currently being tested are meant for oral use, and use a preparation very close to the ideas of Dr. Peat for using long-chain fats and vitamin E to circumvent first-pass metabolism of any steroid and ensure most of the steroid gets absorbed through the lymphatic system. As such, selling AlloP has become very legally risky.<\/p>\n Interestingly enough, the first commercial antidepressant of the SSRI class known as fluoxetine (Prozac) was found to increase the activity and expression of an enzyme called 3\u03b1-hydroxysteroid dehydrogenase (3\u03b1-HSD)<\/a>, which is one of the major steps in synthesizing allopregnanolone from progesterone.<\/p>\n https:\/\/www.ucsf.edu\/news\/1999\/11\/97489\/scientists-identify-new-pathway-antidepressant-action<\/a><\/p>\n https:\/\/www.pnas.org\/doi\/10.1073\/pnas.96.23.13512<\/a><\/p>\n Since levels of allopregnanolone have been consistently found to increase after fluoxetine administration, and allopregnanolone levels were found to be universally low in people with depression (as well as many other brain\/mood conditions) the hypothesis was that it was allopregnanolone that was the true antidepressant, with fluoxetine functioning only as a trigger for the synthesis of that “neurosteroid”.<\/p>\n https:\/\/pubmed.ncbi.nlm.nih.gov\/37746458\/<\/a><\/p>\n However, this hypothesis is incomplete since fluoxetine was found to increase activity and expression of mostly 3\u03b1-HSD, and while this MAY results in higher allopregnanolone levels it does not guarantee it, since the cascade has to also pass through the enzyme 5\u03b1-reductase (5-AR) in order to synthesize allopregnanolone. In fact, the steps of allopregnanolone synthesis are as follows: progesterone -> 5\u03b1-dihydroprogesterone (5-AR activity) -> allopregnanolone (3\u03b1-reductase activity). If fluoxetine selectively increases the activity of only 3\u03b1-HSD, then the only thing that can be said for sure is that fluoxetine would increase the levels of a steroid that takes progesterone as input and produces a 3\u03b1-reduced steroid, which is a steroid with a hydroxyl group (OH) on position C-3, in the alpha configuration. Once progesterone goes through 3\u03b1-HSD, and produces a C-3-ol steroid, the reaction terminates there, since that output steroid cannot undergo processing by 5-AR, as the latter can only accept as input steroids with a keto group on C-3 (progesterone, testosterone, cortisol, etc). However, since the enzyme 3\u03b1-HSD is bi-directional (oxido-reductase), the end steroid output may get converted back to progesterone. The output of the progesterone being processed by 3\u03b1-HSD is the steroid 3\u03b1-Dihydroprogesterone (3\u03b1-DHP)<\/a>, and if fluoxetine works primarily by increasing 3\u03b1-HSD activity and levels, then a more appropriate hypothesis would be that the anti-depressant and anti-anxiety effects of fluoxetine may be due more to the increased levels of 3\u03b1-DHP, and not so much on the increased levels of allopregnanolone.<\/p>\n https:\/\/en.wikipedia.org\/wiki\/3%CE%B1-Dihydroprogesterone<\/a><\/p>\n Interestingly enough, 3\u03b1-DHP has been found to have the same affinity and strength as a GABA agonist as allopregnanolone, and the latter is known as the most potent endogenous GABA agonist agent.

The studies below suggest that it has a number of other interesting effects, at least in animals, include unique anti-cancer effects NOT shared by allopregnanolone<\/strong><\/span>. Since one of the tumor cell lines used in many of those cancer studies was the estrogen-sensitive (ER+) line known as MCF-7, a reasonable conclusion may be that 3\u03b1-DHP has anti-estrogenic effects, not shared by its cousin allopregnanolone, as other estrogen antagonists have also showed anti-cancer effects in MCF-7 models. For the record, 3\u03b1-DHP also demonstrated inhibitory effects on tumor growth from estrogen- and progesterone-negative cell likes, which suggests its effects are generic\/systemic and not only focused on a specific steroid pathway.<\/p>\n https:\/\/pubmed.ncbi.nlm.nih.gov\/25927181\/<\/a><\/p>\n “…Onset and growth of ER\/PR-negative human breast cell tumors were significantly stimulated by 5\u03b1P and inhibited by 3\u03b1HP<\/span><\/strong><\/span>.

Understanding what causes these changes in expression could help in designing protocols to prevent or reverse the changes in progesterone metabolism associated with breast cancer.”<\/p>\n Furthermore, another study demonstrated striking spermatogenic effects of 3\u03b1-DHP, which were much stronger than the spermatogenic effects of testosterone. However, unlike testosterone, DHT and other related steroids, 3\u03b1-DHP did not display androgenic effects. Assuming allopregnanolone has similar effects, I would not be surprised if we soon see clinical trials for allopregnanolone (and\/or, God forbid, 3\u03b1-DHP) as treatments for infertility, especially considering the skyrocketing rates of this issue in most Western\/developed countries.<\/p>\n https:\/\/pubmed.ncbi.nlm.nih.gov\/2502196\/<\/a><\/p>\n “…The effect of 3 alpha-hydroxy-4-pregnen-3-one (3HP), a Sertoli cell steroid, on spermatogenesis was examined in normal and gonadotropin-suppressed rats, through s.c. as well as direct intratesticular injections.

\n3\u03b1-DHP<\/u><\/b> is a liquid (very viscous) product containing a bioidentical endogenous neurosteroid known as 3\u03b1-dihydroprogesterone (3\u03b1-DHP). While that steroid has not been as extensively studied as the closely-related neurosteroid allopregnanolone, 3\u03b1-DHP can perhaps be best described as an allopregnanolone mimetic, with similar (though not identical) pharmacological profile and strength (especially on the GABA system). Some of the more unique and interesting properties of 3\u03b1-DHP include its anti-cancer effects demonstrated in animal studies, with the notable finding that those anti-cancer effects are NOT shared by neither allopregnanolone nor its precursor neurosteroid 5\u03b1-dihydroprogesterone (5\u03b1-DHP). In addition, 3\u03b1-DHP has demonstrated potent spermatogenic and pro-sexual effects in some animal studies, with the former fax exceeding the effects of any other known and tested steroid (e.g. androgens).<\/p>\n
