Pregnenolone and Libido

Sexual desire and function declines with advancing age. This is because the levels of many other hormones that regulate sex drive (testosterone and estrogen) also decline gradually. As the “mother of all hormones”, studies show that pregnenolone can help restore youthful levels of other hormones, thereby ramping up sexual power:
1. Pregnenolone is a precursor for the synthesis of testosterone, [118] the primary male sex hormone known to regulate sex drive and erection.
2. Pregnenolone also boosts the production of estrogen and progesterone in women, [199-120] both of which increases sex drive and improves sexual function.
3. In mice, pregnenolone co-treatment restores the production of sex hormones necessary for maintenance of libido. [121]
