**The synthesis of the [male pheromones](https://phero.com/)..**..

**Cholesterol - \> pregnenolone**

> **[Pregnenolone](https://en.wikipedia.org/wiki/Pregnenolone)**
>
> Pregnenolone (P5), or pregn-5-en-3β-ol-20-one, is an endogenous steroid and precursor/metabolic intermediate in the biosynthesis of most of the steroid hormones, including the progestogens, androgens, estrogens, glucocorticoids, and mineralocorticoids. In addition, pregnenolone is biologically active in its own right, acting as a neurosteroid. In addition to its role as a natural hormone, pregnenolone has been used as a medication and supplement; for information on pregnenolone as a medication or...

**Pregnenolone - \> androstadienol**

> **[Androstadienol](https://en.wikipedia.org/wiki/Androstadienol)**
>
> Androstadienol, or androsta-5,16-dien-3β-ol, is a 16-androstene class endogenous steroid, pheromone, and chemical intermediate to several other pheromones that is found in the sweat of both men and women. Androstadienol and androstadienone are odorless compounds secreted by the apocrine glands, and via conversion into the more powerfully-odorous androstenone and androstenol (catalyzed by aerobic corynebacteria, particularly Corynebacterium xerosis, in men, and Micrococcaceae spp. in women), are c...

**Androstadienol - \> androstadienone (A1)**

> **[Androstadienone](https://en.wikipedia.org/wiki/Androstadienone)**
>
> Androstadienone, or androsta-4,16-dien-3-one, is a 16-androstene class endogenous steroid that has been described as having potent pheromone-like activities in humans. The compound is synthesized from androstadienol by 3β-hydroxysteroid dehydrogenase, and can be converted into androstenone (a more potent and odorous pheromone) by 5α-reductase, which can subsequently be converted into 3α-androstenol or 3β-androstenol (also more potent and odorous pheromones) by 3-ketosteroid reductase. Androstadie...

**Androstenone - \> androstenol (Anol)**

> **[Androstenol](https://en.wikipedia.org/wiki/Androstenol)**
>
> Androstenol, also known as 5α-androst-16-en-3α-ol (shortened to 3α,5α-androstenol or 3α-androstenol), is a 16-androstene class steroidal pheromone and neurosteroid in humans and other mammals, notably pigs. It possesses a characteristic musk-like odor. Androstenol, or a derivative, is found in black truffles. This was offered as an explanation for how pigs locate them deep in the ground: Androstenol is produced in the saliva of male pigs. However, experiments in France using pigs to scent truffle...

**Testosterone - \> androsterone (ERone)**  
Also..  
**Androstedienone (A1) - \> androsterone (ERone)**

> **[Androsterone](https://en.wikipedia.org/wiki/Androsterone)**
>
> Androsterone, or 3α-hydroxy-5α-androstan-17-one, is an endogenous steroid hormone, neurosteroid, and putative pheromone. It is a weak androgen with a potency that is approximately 1/7 that of testosterone. Androsterone is a metabolite of testosterone and dihydrotestosterone (DHT). In addition, it can be converted back into DHT via 3α-hydroxysteroid dehydrogenase and 17β-hydroxysteroid dehydrogenase, bypassing conventional intermediates such as androstanedione and testosterone, and as such, Andr...

(Testosterone also ultimately comes from Cholesterol)
